Functions can have only input parameters for it whereas Procedures can have input or output parameters. Functions can be called from Procedure whereas Procedures cannot be called from a Function.

Why use stored procedures instead SSIS?

Second, the graphical interface lets you build large, complex and reliable transforms much more easily than hand-crafted T-SQL. And third, SSIS lets you more easily interact with additional external sources, which can be very handy for things like data cleansing.

Why stored procedure is better than query?

First, embedding your query inside of a stored procedure increases the likelihood that SQL Server will reuse that query’s cached execution plan as explained above.
