Sp_helptext is a special system stored procedure in Microsoft SQL Server that is used to display the source code to an object such as a stored procedure, trigger, or user-defined function. It is a powerful tool that can provide valuable insights to users on how their procedures, triggers, and functions are working and can assist in troubleshooting and debugging. The positive benefits of using sp_helptext are two-fold - it can help users understand the underlying logic and code behind their stored procedures and functions, and it can help prevent potential SQL injection attacks.

First, sp_helptext can help users understand the underlying logic and functionality of their stored procedures and functions. It allows users to examine and analyze the source code of their procedures and functions and can assist in debugging any issues they may be having with the stored logic. For instance, with sp_helptext users can quickly evaluate their stored procedures and functions and troubleshoot any syntax errors or performance issues they may be experiencing. In addition, it allows users to ensure that their procedures and functions are functioning as expected and that any variables they are utilizing are used properly.

Second, sp_helptext can help prevent SQL injection attacks.
