Oracle Database 12c Security - Oracle Virtual Private Database (VPD)
 
12:29
Learn how to use Oracle Virtual Private Database (VPD) to secure your data. See all lessons at http://skillbuilders.com/12c-TSDP-Tutorial First, Virtual Private Database. What is it? Answer: It's a declarative technique for enforcing security. Typically, it's based on user application context. That was the first limitation of 8i. Backed with 8i context were session-specific. The context variables were sort in the PGA. That means you simply couldn't use this in a web environment. However, global context, with use of 9i, Virtual Private Database became usable for web applications with connection pooling. But whether you're using it to client server or on a three tier environment, it's declarative technique rather than a programmatic technique. I can go behind the back of the application as a DBA and generate predicates to get appended to all SQLs. Select, insert, update, delete the end users. Issue the SQL and I will generate a predicate that filters the access. It's impossible to bypass. All users will have predicates appended to all their code. It doesn't matter whether they're using SQL Plus, Discoverer, Business Objects, Crystal Reports, eBusiness Suites, whatever they're using, I as DBA can filter their access to roles. The end result, different users see different data sets while running the same code and accessing the same tables, hence, the name Virtual Private Database. Different users will think they're seeing a totally different set of tables, but in fact it's one column database, one set of tables hosting a single application shared by all the users. The mechanism - you can apply VPD to tables, to views, to synonyms, and a declarative technique. Once the technique you write a function that generates the predicate, you associate the function with the table. From then on whenever the user issue SQL against that table the Cost-Based Optimizer rewrites the code. The Cost-Based Optimizer rewrites the user SQL to call the function to generate the predicate. The predicate is then appended to the SQL and it's the modified SQL that is parsed and executed. Let's see how this actually works. I'm working here by the way. This is just a perfectly normal 12.1 database. But what I'm going to demonstrate at this point will in fact work on 11g as well. I'm not going to be using any of the 12c enhancements to VPD for this little demonstration. I'll work in the scott schema. What do we have to do? We write a function to generate the predicate string. Create function. And I'll my function vpdf. The function must conform to a fixed specification. It must take two varchar arguments. One of the arguments is intended to be the schema to which the function will be applied. The other argument is the object within the schema to which the function will be applied. And it must return a varchar2, which is the generated predicate. Let's begin. Within this function you can do just about anything. There are some limitations. It's impossible for the function to query or update the table against which the VPD calls here is going to be applied or we violate the rules of purity that we come across so often with PL/SQL. But apart from that, it can do just about anything - including a number of dreadful side effects can be introduced by writing VPD functions. I'm going to do a very simple one on this one. I'll shall simple return immediately a predicate. What predicate? Ename, which is the ename column from this scott.emp table. Ename should equal sys_context. I'll go to the local context, my user end context, and just extract session user. We can see that John has tested this earlier today and therefore the object already was suggesting and he's just dropping it now and cleaning up the recreate. I hope you realize these really are live demonstrations. I'm not just running scripts. I've created a function. What's that function going to do? It's going to return this value here. Test it. Always test it and see what it's actually going to do. I'll select vpdf. I have to give it a couple of arguments. This one will do for now.

Oracle SQL Tutorial 1 - Intro to Oracle Database
 
10:18
As illustrated in the video, Oracle Database is a program designed to hold lots of information, or data. There are all kinds of different databases and they all have their uses. Some of the most common ones are MySQL, SQL Server, Sybase, and MongoDB. All of these have different uses. The differences will be easier to understand after you learn more about each kind of database. We did not discuss it much in the video, but if you are wondering what “SQL” means in the title, it stands for structured query language. Structured query language is a human readable computer language that is used to tell databases to do things. We will discuss SQL and Oracle SQL Developer more in future videos. Databases are better than spreadsheets because they allow multiple users at one time, different levels of access given to users, recovery options and transactions, and it is more protected from hacking and malicious destruction. Programming languages often have very useful functions or methods that can be used to communicate to a database and therefore they are a naturally good option for the back end of programs. This course will go over all of the major parts of database programming using Oracle SQL. We will be using Oracle 11g, but these videos should still work with other versions, including the most recent 12c. Q and A ~~~~~~ How much does Oracle cost? The full enterprise edition costs thousands. They have other versions for less and they even have a FREE VERSION! This is known as the XE version (eXpress Edition). That is the one we will be using. How long does it take to learn SQL? You can learn all of the basics and be an efficient beginner database developer in only about a month of practice. To become an intermediate it can take anywhere from an additional 3 - 6 months with a only a few hours of studying and practicing each day. How can I learn SQL faster? Take notes and actually mess around with making your own database. Watch these videos until you understand the concepts within them, read articles and books that teach in more depth.

SQL injection - Getting the table name  ,  column name  and database name from the database
 
12:25
in this video I will tell you how can get the table name and column and database name from the unknown database. As database connection is written in the server language so we need to run some code before we get to that stage of getting the table name, column name and database from the website To run our sql injection we are going to use, UNION query Step – 1 – In the step one we will try to get the number of column, to do that I will type the user which exist in the database Step – 2 – After knowing the number of column, we will try to get the table name and column name from the database, to do that I will use union query, and I will give below value in the form. Step – 3 – After knowing the table name and database name, we will try to get the table name, in the userprivateinfo table, to do that again I will use union query, and I will give below value in the form. Step – 3 – After knowing the table name and database name and column name, we will run one example to do that again I will use union query, and I will give below value in the form. Note – Although I keep on using Tom, as starting value, for every step, but you can use any value, as it does not matter, weather that value exist in the database or not.

We can also say that SQL tables are kind of data structure which are used by database for efficient storage of data. To create a table in our database we use SQL CREATE TABLE command. SQL CREATE TABLE is a type of DATA DEFINITION LANGUAGE also known as DDL. To Create a table in your schema you will require CREATE TABLE system privilege. In our future videos we will see what are system and object privileges and how to grant them to a user. Today for this video we will be using Sample schema HR which already has all the necessary privileges. Ohk Let's see the syntax. CREATE TABLE table name ( column name1 Data-Type(size), column name2 Data-Type(size), ..... ); CREATE TABLE is an oracle reserved word or say an Oracle key word whereas There are 3 different ways of creating a table in Oracle database. Creating a table using Command Line Interface (CLI) in Oracle database For demonstrating how to create table in oracle database using CLI, I'll be using Command prompt. Thats how we create table using command prompt. you can check your table structure by DESCRIBE command for that just write DESC and your table name. Like this Another way of creating a table is by using Graphic user interface (GUI) in Oracle database To demonstrate how to create table using GUI we will use SQL developer. Lets open our SQL developer I am connected to HR schema if you do not know how to create a connection to database using SQL developer please watch my oracle database tutorial 4 that explains database connectivity using SQL developer and command prompt. Link for this video is in the description below. So lets create a table. Creating a table using SQL developer is very easy we do not have to fire any query here. Let's start First of all right click on your connection in which you want to create a table and choose schema browser. This will open a separate schema browser pane or you can expend your connection by clicking this + sign and then right click on table and choose New Table. However I prefer working with schema browser so let's skip to schema browser pane here from the first drop-down list you can choose connection name and in the second drop down list you can choose what database objects you want to work with we want to create a table thus I'll choose table and then click this arrow here and choose option for new table Ok we have created a table wizard first of all give a unique name to your table and add some column as well. For this, click the green plus button. Now we already have a column so give it some name. Also choose a datatype from the list and specify any size you can check this not null column if in case you want to make this a mandatory column you can also specify default value and constraint If you want to make this column a primary key you can click here In my future video i'll show you what are these constraints and different ways of applying them on a column in a table. for this video we will concentrate on create table only so when you are done with all your columns click ok Thats your table You can double click on your table here and can see its structure. Thats it

How To Kill All Database Processes On SQL Server
 
06:42
SQl management studio provides lot of facilities to manage SQL processes. The “Activity monitor screen” which will show you some very useful and important information about SQL processes. It will show you all active processes, there status, number of open transactions for each process, the application by which the process is generated, Wait time CPU and memory utilisation, and the host name, means the host or the machine by which the process is initiated etc. If a process is hanging, it will show the process icon with an hour glass. Refresh it several times, sometimes the icon will turn to sleep mode if the process completes its execution. If the icon remains an hour glass, the process may be hanging. Use other info as well to decide if the process is really hanging. If you double click on the process ID it will show the SQL stamen subjected to the execution of the process. If a process is hanging you can identify which application has originated the process, which SQL stamen is hanging and even more from which machine or the host the process is initiated If some application users are complaining about uneven slowness, uneven timeouts etcetera, the reason behind may be one or more processors are hanging. What can you do now? You can restart the SQL server or the service which will disconnect all databases and all applications disturbing all the users. Or otherwise you can take the database to off line and bring it back to online. Or you can disconnect all connections to the database. The disturbance may be lesser than the previous case but still lot of applications and users can be disturbed, especially in an industrial setup. And still you do not know the real reason for the slowness or the malfunctioning as well. So what can you do? Go and examine the processors. Identify exactly which process is hanging. And most probably you will be identifying how and why. So you can find permanent solution. But the immediate solution is you can kill the troubling process or the few. It will solve the issue with minimum disturbance immediately. After identifying the correct process, you can right click on the process ID and click on ‘Kill process’ button. It will kill the selected process. You can kill processors using SQL statements and, using SQL commands you can kill all processors at once as well. Code for Killing Processes Individually USE master go DECLARE @dbname sysname SET @dbname = 'YourDB' EXECUTE ('KILL 53') Code for killing all Processes USE master go DECLARE @dbname sysname SET @dbname = 'YourDB' DECLARE @spid int SELECT @spid = min(spid) from master.dbo.sysprocesses where dbid = db_id(@dbname) WHILE @spid IS NOT NULL BEGIN EXECUTE ('KILL ' + @spid) SELECT @spid = min(spid) from master.dbo.sysprocesses where dbid = db_id(@dbname) AND spid @spid END

Creating a database, table, and inserting - SQLite3 with Python 3 part 1
 
10:59
Welcome to an SQLite mini-series! SQLite, as the name suggests, is a lite version of an SQL database. SQLite3 comes as a part of the Python 3 standard library. Databases offer, typically, a superior method of high-volume data input and output over a typical file such as a text file. SQLite is a "light" version that works based on SQL syntax. SQL is a programming language in itself, but is a very popular database language. Many websites use MySQL, for example. SQLite truly shines because it is extremely lightweight. Setting up an SQLite database is nearly instant, there is no server to set up, no users to define, and no permissions to concern yourself with. For this reason, it is often used as a developmental and protyping database, but it can and is used in production. The main issue with SQLite is that it winds up being much like any other flat-file, so high volume input/output, especially with simultaneous queries, can be problematic and slow. You may then ask, what really is the difference between a typical file and sqlite. First, SQLite will let you structure your data as a database, which can easily be queried, so you get that functionality both with adding new content and calling upon it later. Each table would likely need its own file if you were doing plain files, and SQLite is all in one. SQLite is also going to be buffering your data. A flat file will require a full load before you can start querying the full dataset, SQLite files don't work that way. Finally, edits do not require the entire file to be re-saved, it's just that part of the file. This improves performance significantly. Alright great, let's dive into some SQLite. https://pythonprogramming.net/sql-database-python-part-1-inserting-database/ Playlist: https://www.youtube.com/playlist?list=PLQVvvaa0QuDezJh0sC5CqXLKZTSKU1YNo https://pythonprogramming.net https://twitter.com/sentdex https://www.facebook.com/pythonprogramming.net/ https://plus.google.com/+sentdex

What a transaction is 2. The problems that might arise when tarnsactions are run concurrently 3. The different transaction isolation levels provided by SQL Server to address concurrency side effects First let us understand what is a transaction A transaction is a group of commands that change the data stored in a database. A transaction, is treated as a single unit of work. A transaction ensures that, either all of the commands succeed, or none of them. If one of the commands in the transaction fails, all of the commands fail, and any data that was modified in the database is rolled back. In this way, transactions maintain the integrity of data in a database. Example : The following transaction ensures that both the UPDATE statements succeed or both of them fail if there is a problem with one UPDATE statement. -- Transfer $100 from Mark to Mary Account BEGIN TRY BEGIN TRANSACTION UPDATE Accounts SET Balance = Balance - 100 WHERE Id = 1 UPDATE Accounts SET Balance = Balance + 100 WHERE Id = 2 COMMIT TRANSACTION PRINT 'Transaction Committed' END TRY BEGIN CATCH ROLLBACK TRANSACTION PRINT 'Transaction Rolled back' END CATCH Databases are powerful systems and are potentially used by many users or applications at the same time. Allowing concurrent transactions is essential for performance but may introduce concurrency issues when two or more transactions are working with the same data at the same time. Some of the common concurrency problems Dirty Reads Lost Updates Nonrepeatable Reads Phantom Reads We will discuss what these problems are in detail with examples in our upcomning videos One way to solve all these concurrency problems is by allowing only one user to execute, only one transaction at any point in time. Imagine what could happen if you have a large database with several users who want to execute several transactions. All the transactions get queued and they may have to wait a long time before they could get a chance to execute their transactions. So you are getting poor performance and the whole purpose of having a powerful database system is defeated if you serialize access this way. At this point you might be thinking, for best performance let us allow all transactions to execute concurrently. The problem with this approach is that it may cause all sorts of concurrency problems (i.e Dirty Reads, Lost Updates, Nonrepeatable Reads, Phantom Reads) if two or more transactions work with the same data at the same time. SQL Server provides different transaction isolation levels, to balance concurrency problems and performance depending on our application needs. Read Uncommitted Read Committed Repeatable Read Snapshot Serializable The isolation level that you choose for your transaction, defines the degree to which one transaction must be isolated from resource or data modifications made by other transactions. Depending on the isolation level you have chosen you get varying degrees of performance and concurrency problems. The table here has the list of isoltaion levels along with concurrency side effects. Isolation Level Dirty Reads Lost Update Nonrepeatable Reads Phantom Reads Read Uncommitted Yes Yes Yes Yes Read Committed No Yes Yes Yes Repeatable Read No No No Yes Snapshot No No No No Serializable No No No No If you choose the lowest isolation level (i.e Read Uncommitted), it increases the number of concurrent transactions that can be executed at the same time, but the down side is you have all sorts of concurrency issues. On the other hand if you choose the highest isolation level (i.e Serializable), you will have no concurrency side effects, but the downside is that, this will reduce the number of concurrent transactions that can be executed at the same time if those transactions work with same data. In our upcoming videos we will discuss the concurrency problems in detail with examples

How to disconnect all connections on sql server database |kill all connections |disconnect all users
 
03:06
use master ALTER DATABASE YourDatabase SET SINGLE_USER WITH ROLLBACK IMMEDIATE --do you stuff here ALTER DATABASE YourDatabase SET MULTI_USER This video is about killing or disconnect all connections to a database. The easiest way is bringing the database to single user mode and set it back to multiuser mode. This will disconnect all connections form all the users other than current one who is logged to the database. One important aspect here is, do not close the screen once you set the database to single user mode. Because when a database is in single user mode it will allow only a single connection to the database. If you allow dropping your connection and if any other connects to the database you will not be able to connect the database again. So you may have to Stop the SQL server and start again to connect the database. It is also possible to do this using SQL management studio. Right click on the database, go to properties, go to options and move to restrict access option. There you can select the single user mode or multiple user mode. Now The question is why do you need to do this. I mean when, do you want to kill all connections. It is mainly, when you want to have exclusive access to the database. For example a database is not allowing you to restore a backup on this because you cannot grant the exclusive access, then you can bring the database to single user mode; killing all connections; perform your activates and after that set it to the multi user mode. This way you can maintain the exclusive access while you are completing the work.
