Useful System Stored Procedures in SQL

In this article we will show you, some of the Useful System Stored Procedures in SQL. These procedures will help you to extract the definition, and dependencies of the existing stored procedures. I suggest you to refer Introduction to Stored Procedure article to understand the basics of the stored procedure.

Following three stored procedures are very useful to deal with user defined procedures:

• sp_help : This procedure will show you the Stored procedure Name, Schema Name, created date and Time. If there are any parameters then, Parameter Name, Data Type, Length, Precision, Scale, Collation etc.
• sp_helptext : Displays the definition of the stored procedure. if the procedure is encrypted then this sp_helptext will not return any definition.
• sp_depends : It will show all the dependencies. This is useful to check on which table the stored procedure is depending on.

For this demonstration, We are going to use the below shown SQL table
