Reusable: Stored procedures can be executed by multiple users or multiple client applications without the need of writing the code again. Reduced network traffic: When we use stored procedures instead of writing T-SQL queries at the application level, only the procedure name is passed over the network instead of the whole T-SQL code. so, when we want to change the logic inside the procedure we can just do it by simple ALTER PROCEDURE statement. SQL Server Stored procedures eliminate such challenges by storing the code in the database. For example, If the T-SQL queries are written in the application and if we need to change the logic, we must change the code in the application and re-deploy it. It can be easily modified: We can easily modify the code inside the stored procedure without the need to restart or deploying the application. To understand differences between functions and stored procedures in SQL Server, you can refer to this article, Functions vs stored procedures in SQL Server and to learn about Partial stored procedures in SQL Server, click Partial stored procedures in SQL Server.
