The NOCOPY parameter hint tells the PL/SQL compiler to pass OUT and IN-OUT parameters "by reference" (meaning: do not copy in, nor copy out). The result is better performance and reduced PGA consumption. ====================================== Practically Perfect PL/SQL with Steven Feuerstein Copyright © 2015 Oracle and/or its affiliates.

https://www.quest.com/products/toad-for-oracle/ Creating unit tests for PL/SQL code is an important developer task that doesn’t often get done because it’s difficult and time consuming. As more companies try to bring database change management into DevOps, the absence of tests and a way to automate their execution becomes a major roadblock. Toad provides a really simple way to overcome that roadblock.

You can also have stored procedures with no/multiple parameters -Execute the newly created stored procedure using SSMS (this generates code to execute a stored procedure automatically) -Modify the generated code (to execute stored procedure) and re-execute the same (multiple number of times).

Microsoft SQL Server is a relational database management system developed by Microsoft. As a database, it is a software product whose primary function is to store and retrieve data as requested by other software applications, be it those on the same computer or those running on another computer across a network (including the Internet). There are at least a dozen different editions of Microsoft SQL Server aimed at different audiences and for workloads ranging from small single-machine applications to large Internet-facing applications with many concurrent users. Its primary query languages are T-SQL and ANSI SQL. This video is targeted to blind users. Attribution: Article text available under CC-BY-SA Creative Commons image source in video

Where databases are more complex they are often developed using formal design and modeling techniques. The database management system (DBMS) is the software that interacts with end users, applications, and the database itself to capture and analyze the data. The DBMS software additionally encompasses the core facilities provided to administer the database. The sum total of the database, the DBMS and the associated applications can be referred to as a "database system". Often the term "database" is also used to loosely refer to any of the DBMS, the database system or an application associated with the database. Computer scientists may classify database-management systems according to the database models that they support. Relational databases became dominant in the 1980s. These model data as rows and columns in a series of tables, and the vast majority use SQL for writing and querying data. In the 2000s, non-relational databases became popular, referred to as NoSQL because they use different query languages.
