MySQL 33 - Datetime, Date, Time Data Types
 
06:40
Next up on our MySQL to-do list is to learn about storing dates and times. There are various data types in MySQL for storing dates and times. It seems MySQL and databases likes to break everything up into multiple data types to make things more organized at the consequence of being confusing and annoying. This video is going to be talking about the DATETIME, DATE, and TIME data types. These are all used to store, you guessed it, dates and times. The one you choose depends on your needs. If you just need dates, choose DATE. If you just need times, choose TIME, if you need both stored together, choose DATETIME. Now you set a column one of these data types whenever you want every row for this field to have some sort of date, time or both…but how exactly is the data formatted? This requires us to understand some convention. For example, in the USA at least, if you have something like 4:30AM, by convention you know the hour is 4 and the minutes are 30. But this is just an agreed upon convention. MySQL has its own convention…For example 2017-02-02. The first thing is the year, the second is the month, and the third is the day. That is for the DATE. The convention for time is 22:54:30. The first is the hour (military time), the second is the minute, and the third is the seconds. Lastly, there can actually be fractions of seconds…up to microseconds! .123456. To use fractional seconds though you must specify to MySQL the precision of the TIME or DATETIME when you create it, for example DATETIME(6) would allow microsecond precision. How do you actually give a date to MySQL? By that I mean let's say you have a table with a column of DATETIME(6), and you want to give a value for that column, how do you format it? It's quoted. For example: '2017-02-02 22:54:30.333333' MySQL interprets this as a DATETIME. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Support me! http://www.patreon.com/calebcurry Subscribe to my newsletter: http://bit.ly/JoinCCNewsletter Donate!: http://bit.ly/DonateCTVM2. ~~~~~~~~~~~~~~~Additional Links~~~~~~~~~~~~~~~ More content: http://CalebCurry.com Facebook: http://www.facebook.com/CalebTheVideoMaker Google+: https://plus.google.com/+CalebTheVideoMaker2 Twitter: http://twitter.com/calebCurry Amazing Web Hosting - http://bit.ly/ccbluehost (The best web hosting for a cheap price!)

Oracle TO_CHAR Function
 
04:13
https://www.databasestar.com/oracle-to_char/ The Oracle TO_CHAR function is a common and useful string manipulation function. It allows you to convert a number or a date value into a string value. It allows you to take a number or a string, and convert it to a VARCHAR2 data type. The syntax of the function is: TO_CHAR( input_value, [format_mask], [nls_parameter] ) The parameters are: - input_value: this is the value to convert to a VARCHAR2 value. It can be one of many different number or date data types. - format_mask is an optional parameter and allows you to specify the format to display the output as. If this is omitted, the function uses a default format. - nls_parameter: this is also optional and lets you determine a regional parameter for displaying the output value. The format mask helps you determine what your output is displayed as. For example, if you provide the date of May 3rd, and the output is ‘03/05/2018’, how do you know if this is May 3rd or March 5th? Using a format mask can specify which format is used. The function is similar to the TO_NUMBER and TO_DATE functions, in that they both convert a specific data type. For more information about the Oracle TO_CHAR function, including all of the SQL shown in this video and the examples, read the related article here: https://www.databasestar.com/oracle-to_char/

Oracle SQL Tutorial 32 - VARCHAR2 and NVARCHAR2
 
03:06
This video we are going to discuss the VARCHAR2 and the NVARCHAR2 data types. The previous videos are a good foundation to this video. I've actually discussed so much stuff in those videos that I don’t have a whole lot to say. Good for you, right? I discussed over the previous videos that you should prefer to use VARCHAR2 over CHAR. That's because there is not a difference in performance or storage for a VARCHAR2 column. The only difference is that an CHAR column forces each value to take up a certain length even if it's not. There is one difference between the variable length and fixed length data types here that you need to know about, and that is storage limits. CHAR has a limit of 2000 bytes, while VARCHAR2 has a limit of 4000 bytes. That means you can store twice as much junk in a VARCHAR2 column! Other than that, these data types work exactly the same. I recommend you always use the VARCHAR2 data types instead of the CHAR data types, and only use NVARCHAR2 if you have a non-Unicode database. This will allow you to store Unicode characters in a column. Now, the amount of storage you can put in a VARCHAR2 column is twice what you can put in a CHAR column, but 4000 characters is still not very many characters. This is where the LOB data types come in, which we will discuss in the next video! ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Support me! http://www.patreon.com/calebcurry Subscribe to my newsletter: http://bit.ly/JoinCCNewsletter Donate!: http://bit.ly/DonateCTVM2. ~~~~~~~~~~~~~~~Additional Links~~~~~~~~~~~~~~~ More content: http://CalebCurry.com Facebook: http://www.facebook.com/CalebTheVideoMaker Google+: https://plus.google.com/+CalebTheVideoMaker2 Twitter: http://twitter.com/calebCurry Amazing Web Hosting - http://bit.ly/ccbluehost (The best web hosting for a cheap price!)

Oracle SQL Tutorial 24 - Important Data Types
 
06:09
In the upcoming videos we are going to discuss data types in depth, but I don't want to drown you in all of the details. Because of that, I'm giving you this video which is going to introduce you to the most important data types. Then, in the upcoming videos, I'll describe them in more depth. One of the data types we've already discussed in this video is NUMBER. This data type is used to, obviously, store a number. It can be used to store integers (whole numbers), or numbers with decimals. There are two other numeric data types you should know of. BINARY_FLOAT and BINARY_DOUBLE are both numeric data types that are known as floating point numbers. A floating point number is often used for large numbers that have decimal places where it is acceptable to not be completely precise. What I mean by this is that these numbers can only store numbers correctly up to a certain decimal point. If you need perfect precision, you will want to use the NUMBER data type. Now storing numbers is good sometimes, but occasionally you will want to store string data. String data can be any sequence of characters, including numbers. By telling the database that a column is a string data type, the database knows how to treat that column. There are four important string data types that you need to know about. The first two are CHAR and NCHAR. These data types are used to store a fixed-length string. So for example, you can say you want to store 12 characters. This means that every value for this column will be exactly 12 characters. If you insert less than 12 characters, the data will be padded with spaces. This means you will want to use one of these data types when every value in the column is the same length. What is the difference between CHAR and NCHAR? CHAR uses what is known as ASCII while NCHAR uses Unicode. The difference is what characters are allowed and how much space each character takes. ASCII takes up less space but only supports English, numbers, and some symbols. UNICODE allows you to store characters from multiple languages but takes up more space. Those were both fixed-length string. What if you want to store data that changes in length? That is where VARCHAR2 and NVARCHAR2 come in. When it comes to storing dates, the data types that are most important are DATE and TIMESTAMP. Date can be used to store dates and time. Timestamp is a data type that can be used to store an exact moment in time. Lastly, there are interval types. These store a date range. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Support me! http://www.patreon.com/calebcurry Subscribe to my newsletter: http://bit.ly/JoinCCNewsletter Donate!: http://bit.ly/DonateCTVM2. ~~~~~~~~~~~~~~~Additional Links~~~~~~~~~~~~~~~ More content: http://CalebCurry.com Facebook: http://www.facebook.com/CalebTheVideoMaker Google+: https://plus.google.com/+CalebTheVideoMaker2 Twitter: http://twitter.com/calebCurry Amazing Web Hosting - http://bit.ly/ccbluehost (The best web hosting for a cheap price!)

SQL Server 30 - How to INSERT Data
 
05:48
Now that we have our tables created, we need to learn how to actually put data into our tables. That is where the INSERT command comes in. The basic syntax looks like: INSERT INTO TableName VALUES(data…); Data is where we put a value for each column. Strings are single quoted, numbers are left blank with no quotes. Just like when we create tables we try to create the parent tables first, we do the same with inserting data. We always want to insert the parent rows first. So let's add a species to our table. As a reminder, this is what our CREATE TABLE looks like: CREATE TABLE Species( ID INT PRIMARY KEY IDENTITY, Species VARCHAR(50) NOT NULL UNIQUE, FriendlyName VARCHAR(50) NOT NULL ); Now to insert data: INSERT INTO Species VALUES('Pentalagus P. furnessi', 'Bunny'); Now you can see that there may a violation of everything being atomic because we are actually storing the genus and species of this animal in one column. But…YOLO. Now we can view this data by finding the table in the object explorer, right clicking, and selecting Edit Top 200 Rows. Notice that the IDENTITY column is automatically filled. Now, this is a great time to show you some stuff regarding foreign keys. The first thing I want to show you is how they protect our data integrity. Let's insert some data in the Animals table and try to reference an invalid species. Once again, here is what our table creation looks like: CREATE TABLE Animals( ID INT PRIMARY KEY IDENTITY, Name VARCHAR(50) NOT NULL, Species INT NOT NULL REFERENCES Species(ID), ContactEmail VARCHAR(50) NOT NULL UNIQUE ); INSERT INTO Animals VALUES('Sally', 2, '[email protected]'); SQL Server does not let us insert this data. The second thing I wanted to show you is that the name of the constraint that is in violation is being shown here. That is why naming your constraints can come in handy so when this happens you can find it much easier. Last thing is that if you want to INSERT multiple rows, throw a comma after the VALUES, and put another parenthesis with more data: INSERT INTO Animals VALUES('Sally', 1', '[email protected]'), ('Franklin', 1, '[email protected]') ; Maybe someday we will get around to adding a row to our species table for turtles, but for now we are going to make Franklin a bunny. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Support me! http://www.patreon.com/calebcurry Subscribe to my newsletter: http://bit.ly/JoinCCNewsletter Donate!: http://bit.ly/DonateCTVM2. ~~~~~~~~~~~~~~~Additional Links~~~~~~~~~~~~~~~ More content: http://CalebCurry.com Facebook: http://www.facebook.com/CalebTheVideoMaker Google+: https://plus.google.com/+CalebTheVideoMaker2 Twitter: http://twitter.com/calebCurry Amazing Web Hosting - http://bit.ly/ccbluehost (The best web hosting for a cheap price!)

Oracle SQL Tutorial 13 - How to Add Column Constraints (Attributes)
 
05:55
So far, we have this table declaration: CREATE TABLE users( user_id NUMBER, username VARCHAR(50 CHAR) first_name VARCHAR2(50 CHAR), last_name VARCHAR2(50 CHAR) ) We can run this command see that it works. As we are learning though, we are going to want to be able to recreate our table with different settings and such, but if you try to run this command, it will complain that the table already exists. So we first need to delete this table before we start editing settings. When we get more experienced, we will learn about ways to edit the structure of a table that already exists. To fix this, we can get rid of the table using the DROP TABLE command: DROP TABLE users You can run this every time if you need to practice by adding a semicolon after it. This is how you can tell Oracle that you are putting in another command after it. This is known as a delimiter. When you run the script, it is going to run both commands. Now we can go through and reconsider our table structure. This is fine for starting out because we don't have any important data in our database, but once your database is in production you are not going to want to just drop tables. In the last video we discussed different constraints that you can apply to columns in a database table, but how do you actually apply these when you are creating a table? The first way you define constraints is to put them right after the column in your CREATE TABLE statement. CREATE TABLE users( username VARCHAR2(50 CHAR) NOT NULL ) When we define constraints this way, we usually say we are adding column attributes. If you have two constraints you want to add, you just put one after the other with spaces in between. There is no particular order that is required. CREATE TABLE users( username VARCHAR2(50 CHAR) NOT NULL UNIQUE ) In this situation we have already given the column the NOT NULL and UNIQUE attributes, so we should consider making this a primary key: CREATE TABLE users( username VARCHAR2(50 CHAR) PRIMARY KEY ) As you can see, adding column attributes is super easy. We can add a default like this: CREATE TABLE users( username VARCHAR2(50 CHAR) PRIMARY KEY, account_balance NUMBER DEFAULT 0 ) Note that now we need the comma after the first row. There are a few constraints we did not talk go through an example, specifically foreign keys and check constraints. We will be adding these constraints to our database in future videos. In the mean time, I have a thought for you… Many people prefer to name their column constraints. That way, we can refer to certain constraints by name. For example, we might have a primary key constraint that could be named users_pk. The way we are creating these constraints does not allow for this feature, so in the next video we are going to be discussing different ways to create constraints. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Support me on Patreon! http://www.patreon.com/calebcurry Subscribe to my newsletter: http://bit.ly/JoinCCNewsletter Donate!: http://bit.ly/DonateCTVM2. ~~~~~~~~~~~~~~~Additional Links~~~~~~~~~~~~~~~ More content: http://CalebCurry.com Facebook: http://www.facebook.com/CalebTheVideoMaker Google+: https://plus.google.com/+CalebTheVideoMaker2 Twitter: http://twitter.com/calebCurry Amazing Web Hosting - http://bit.ly/ccbluehost (The best web hosting for a cheap price!)

Session 6: Datatypes In Oracle   ALPHABET           : A-Z , a-z NUMBER              : 0-9 (with precision and scale) DATE / Temporal  : any Date and time (Hours, Minutes, Seconds, Mili-seconds, Timestamp, Timezone etc)   Alphabet + Number = Alphanumeric Data                                     = String / CHARACTER Datatype Category Number                    =  Numeric Datatype Category Date                         = Date Datatype Category 1. CHARACTER Datatype: CHAR, VARCHAR, NCHAR: CHAR is fixed length datatype and VARCHAR is Variable length datatype to store character data. i.e. A-Z , a-z , 0-9 , all keyboard characters etc. The default size is 1 character and it can store maximum up to 2000 bytes. Example : EName, EmpID, PassportNo, SSN, etc. EName CHAR(10) := ‘TOM’; wastage of 7 space after the string EName VARCHAR(10) := ‘TOM’; Spaces can be Reuse which left after the string NCHAR additionally handles NLS(National Language Support). Oracle supports a reliable Unicode datatype through NCHAR , NVARCHAR2 , and NCLOB  VARCHAR2, NVARCHAR2: These are Variable length datatype. VARCHAR2 handles alphanumeric character string whereas NVARCHAR2 handles alphanumeric character string with NLS(National Language Support). The default size is 1 character and it can store maximum up to 4000 bytes.   LONG:  Variable length string.  (Maximum size: 2 GB - 1) Only one LONG column is allowed per table. RAW:    Variable length binary string (Maximum size 2000 bytes) LONG RAW: Variable length binary string (Maximum size 2GB) 2. NUMERIC Datatype: NUMBER: It stores Numeric values and performs numeric calculations. NUMBER,   NUMBER(n),   NUMBER(p,s) It stores Numbers up to 38 digits of precision. SeqNo NUMBER;                     1, 123, 12345678 EmpID NUMBER(4);                 1, 123, 1234 Sal NUMBER(7,2);                     23456.78 , 123.45 — correction in video: Sal NUMBER(a7,2); which is wrong please ignore. 1234567 can be a type of NUMBER, NUMBER(7), NUMBER(7,0) It can store both integer and floating point numbers NUMERIC(p,s) FLOAT:   Ex:  EmpSal FLOAT;    FLOAT(7)       Decimal Points allowed DEC(p,s), DECIMAL(p,s) , REAL, DOUBLE PRECISION INTEGER:   Ex:  SSN INTEGER;       Decimal Points are not allowed INT, SMALLINT 3.

Oracle SQL Tutorial 23 - Intro to Data Types
 
05:03
Every column within a table has to be given what is known as a datatype. A data type is a fairly simple concept when you dissect the word. It is literally the type of data. Why do we use types, though? The biggest benefit is so that Oracle knows how to interpret and work with our data. It also makes the database better at rejecting incorrect data. If we had to concept of a data type, there would be a lot more work involved in forcing data to be of the right format. It would also be harder for us to get the database to treat the data in the correct way. In addition to this, a database can optimize storage and performance for a column if everything is of the same data type. Because of this, each column can only support one data type. There are numerous different data types in Oracle and it helps us if we categorize them. The first types of datatypes we should learn about are: String, Numeric, Temporal Now, there are few more categories we could make, but these are the main ones. We will worry about the other ones another day as I am only introducing the topic. A string data type is anything within quotes. Most databases use single quotes for string data. Inside of the quotes can be any number of characters. What is a character? Think of any letter, number, or symbol you can type. Some people call these letters, numbers, and symbols alphanumeric. Numeric data type includes only numbers. These data types are often used for data that you plan on using for mathematical calculations. Temporal data types are data types that are used for dates and times. Now, each data type is probably going to have some options you'll need to worry about, but one that comes up with every data type is storage. The reason we need to consider storage is because we may end up with millions of rows in a table and the difference between a few bytes for each row will make a huge difference when we look at the whole picture. When a data type gives you the option of size, you will want to a size that will be able to hold what you need, but nothing more. In the upcoming videos we are going to discuss the available data types in more detail. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Support me! http://www.patreon.com/calebcurry Subscribe to my newsletter: http://bit.ly/JoinCCNewsletter Donate!: http://bit.ly/DonateCTVM2. ~~~~~~~~~~~~~~~Additional Links~~~~~~~~~~~~~~~ More content: http://CalebCurry.com Facebook: http://www.facebook.com/CalebTheVideoMaker Google+: https://plus.google.com/+CalebTheVideoMaker2 Twitter: http://twitter.com/calebCurry Amazing Web Hosting - http://bit.ly/ccbluehost (The best web hosting for a cheap price!)

Oracle SQL Tutorial 29 - NCHAR Part 1
 
04:58
NCHAR is another data type available in Oracle database. This data type is very similar to the char data type with some key differences. NCHAR is also known as the national character set. This is a data type that allows us to store Unicode characters. It is really recommended that you watch the two videos over Unicode and UTF-8 because this video is going to talk a lot about it. Why is it that we have an entire data type dedicated to storing Unicode? That will be easily understood once we understand how character sets and encodings are applied to Oracle. They are applied at the database level. That means that you have a character set that applies to the entire database. This is in contrast to some database management systems that allow you to apply a data type at the table and column level. For example, in MySQL you can make a table have a character set, and make a specific column in that table a different character set. That means we can customize everything at the expense of adding potential complexity and confusion. Oracle does not work that way. In Oracle, we define one character set for the entire database. The problem with defining a character set for the entire database is that it may not be the character set we want to use for everything. That is where the NCHAR column comes in. The NCHAR column allows us to have a Unicode column inside of a database that does not use Unicode as the default character set. That is important because it is very often that we want to use Unicode but we may not need to use it for everything, for example if that application is working with ASCII nearly all of the time. If you are using Unicode for the database, then NCHAR is not going to be needed and should not be used. This data type is not as widely accepted, so only use it if you absolutely need to, specifically when you need to store Unicode in a non-Unicode database. Additionally, there is some controversy when it comes to whether or not you should use the CHAR and NCHAR data types in Oracle at all. We will discuss why in an upcoming video. In the next video we are going to go over some specific character sets that Oracle can use. See you then! ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Suppor me! http://www.patreon.com/calebcurry Subscribe to my newsletter: http://bit.ly/JoinCCNewsletter Donate!: http://bit.ly/DonateCTVM2. ~~~~~~~~~~~~~~~Additional Links~~~~~~~~~~~~~~~ More content: http://CalebCurry.com Facebook: http://www.facebook.com/CalebTheVideoMaker Google+: https://plus.google.com/+CalebTheVideoMaker2 Twitter: http://twitter.com/calebCurry Amazing Web Hosting - http://bit.ly/ccbluehost (The best web hosting for a cheap price!)

Oracle SQL Tutorial 27 - CHAR Part 1
 
03:52
This video and the next is going to cover CHAR and NCHAR. Be sure to check out the previous two videos as these are going to introduce you to some foundational knowledge required to understand these data types. CHAR is a fixed-length data type. What that means is that every value for a CHAR column is going to be the same length. You specify the length in parenthesis when you create the table. The thing you need to know though is that the default measurement is in bytes. That means if you specify the length to be CHAR(50), the length of each value will be 50 bytes, by default. If you want to change that to 50 characters, you can pass in the word CHAR as in CHAR(50 CHAR). This is known as a qualifier. Specifically, they are known as length semantics qualifiers (describes the meaning of the given length). Now, I said the default was bytes, but you can actually change the default to characters. In that situation, you can actually use the keyword BYTE to break away from the default. In general, it's best to put CHAR or BYTE even if it is the default. In general, it's best to keep things consistent. It's okay to have these measured in CHAR or BYTE, but it is recommended that every column is the same. It allows you to be more consistent as if some columns measure length in bytes and some measure length in characters, things can get confusing. If you do want to change the default, look up NLS_LENGTH_SEMANTICS as well as the potential problems it may bring. What values are allowed in parenthesis? That is what we are going to discuss in the next video. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Support me! http://www.patreon.com/calebcurry Subscribe to my newsletter: http://bit.ly/JoinCCNewsletter Donate!: http://bit.ly/DonateCTVM2. ~~~~~~~~~~~~~~~Additional Links~~~~~~~~~~~~~~~ More content: http://CalebCurry.com Facebook: http://www.facebook.com/CalebTheVideoMaker Google+: https://plus.google.com/+CalebTheVideoMaker2 Twitter: http://twitter.com/calebCurry Amazing Web Hosting - http://bit.ly/ccbluehost (The best web hosting for a cheap price!)

Use the type conversion functions to change the type of an argument. StringToDate Returns a date from the given string in the given format. You do not have to specify a format string if your string contains a date in the default format yyyy-mm-dd. Input: string (string) [,format (string)] Output: result (date) Examples: If the column mylink.mystring contains the string ″1958--08--18″, then the following function returns the date 1958--08--18. StringToDate(mylink.mystring) If the column mylink.mystring contains the string ″18:08:1958″, then the following function returns the date 1958--08--18. StringToDate(mylink.mystring,"%dd:%mm:%yyyy")

Oracle SQL Tutorial 11 - CREATE TABLE
 
05:04
The way you create a table is to use the CREATE TABLE command. CREATE TABLE users() So in this situation, the name comes right after the TABLE keyword. The next thing we do is put all of the columns on a line that we want to put in our table. CREATE TABLE users( user_id, username, first_name, last_name ) Notice the naming conventions here. For this series we are going to make columns with what is known as snake casing. This is where each individual word is separated by an underscore. if you have more than one column, all of them have to have commas except the last one. The comma is a way to say that another column is coming, so you don't need to do it on the last one. Now you would think we were done, but we also have to say what data type each column is. Later we will extensively discuss data types so we can focus on them exclusively. For now, here are the data types we are going to use: CREATE TABLE users( user_id NUMBER, username VARCHAR2(50), first_name VARCHAR2(50), last_name VARCHAR2(50) ) Now, inside of the parenthesis for varchar2, we pass in a number... This is the max length of the string. But the question is, what is it measured in? The default is actually in bytes, not characters. For example if we have the string hello, it is 5 characters, but it might take up a total of 10 bytes of storage. So I would recommend adding the keyword char right after the number so it defaults to 50 characters, not bytes. CREATE TABLE users( user_id NUMBER, username VARCHAR(50 CHAR), first_name VARCHAR2(50 CHAR), last_name VARCHAR2(50 CHAR) ) This will work to create a table, but it's really missing a lot of information… which column is the primary key? Are we adding any indexes? Is there any thing else we need to say about these columns? So as you can tell, we are making progress, but there is still so much to learn. The biggest gotcha to remember from this video is that the data type VARCHAR ends in a 2, stupid, right? who would end the name of something with a 2? Once again, this is Caleb from CalebTheVideoMaker2, and we will catch you in the next one! ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ HELP ME! http://www.patreon.com/calebcurry Subscribe to my newsletter: http://bit.ly/JoinCCNewsletter Donate!: http://bit.ly/DonateCTVM2. ~~~~~~~~~~~~~~~Additional Links~~~~~~~~~~~~~~~ More content: http://CalebCurry.com Facebook: http://www.facebook.com/CalebTheVideoMaker Google+: https://plus.google.com/+CalebTheVideoMaker2 Twitter: http://twitter.com/calebCurry Amazing Web Hosting - http://bit.ly/ccbluehost (The best web hosting for a cheap price!)

This video will teach you how to create sequence objects with working examples, within SQL Server, we also look at the benefits of sequence objects and some of the differences between a sequence object and identity. CREATE SEQUENCE 'name' AS 'data type' START WITH 'value' INCREMENT BY 'value' MINVALUE 'value' (optional – will default to data type range) MAXVALUE 'value' (optional – will default to data type range) CYCLE? (optional – will default to NO CYCLE) How to find details of sequence objects within the database: sys.sequences – will show all information regarding sequence objects including current value How to restart the value of a sequence object: ALTER SEQUENCE 'name' RESTART WITH 'value' How to drop a sequence: DROP SEQUENCE 'name' (cannot drop a sequence if it is in use!) How to generate the next value for a sequence: SELECT NEXT VALUE FOR 'name' Sequences are covered in the Microsoft Exam – Querying SQL Server (70-461) 2012 / 2014. SQL Statements used below: CREATE SEQUENCE seq_test AS TINYINT START WITH 1 INCREMENT BY 1 MINVALUE 1 MAXVALUE 100 CYCLE CREATE TABLE Food_Orders ( Id TINYINT DEFAULT NEXT VALUE FOR seq_test , [Date] DATETIME2 , Summary VARCHAR(100) ) CREATE TABLE Food_Orders_2 ( Id TINYINT DEFAULT NEXT VALUE FOR seq_test , [Date] DATETIME2 , Summary VARCHAR(100) ) -- loop to insert data to test sequence DECLARE @N TINYINT = 1 WHILE @N 'less than' 110 BEGIN INSERT INTO Food_Orders([Date], Summary) VALUES (CURRENT_TIMESTAMP, 'Burger and Chips') INSERT INTO Food_Orders_2([Date], Summary) VALUES (CURRENT_TIMESTAMP, 'Burger and Chips') SET @N = @N + 1 END SELECT NEXT VALUE FOR seq_test ALTER SEQUENCE seq_test RESTART WITH 1 DROP SEQUENCE seq_test CREATE SEQUENCE seq_new AS INT START WITH 1 INCREMENT BY -1 SELECT NEXT VALUE FOR seq_new SQL errors covered: The sequence object 'name' has reached its minimum or maximum value. Restart the sequence object to allow new values to be generated Cannot DROP SEQUENCE 'name' because it is being referenced by object 'name'
