Below link may help you to Create new Procedure in SQl Server.

You can have multiple Queries in your SQL Procedure, And it will return you multiple recordsets based on number of select queries you used in your Procedure.

A step by step tutorial[^].
The short of it...

SQL

create procedure [procedure_name]
   -- optionally some params.
   @status char(1)
as
   --your query here
   select someStuff
   from someTable
   where status = @status
end

This SP returns someStuff from someTable where the status is equal to the parameter provided.
Hope that helps! :)

Edit:
I may imply that only simple select statements are possible in an SP. This is not the case however, you can do joins, updates, deletes, use cursors, loops, temp tables, practically do anything in an SP. It doesn't necissarily need a return value either.
