Question

I’m new to SQL Server. Currently I’m working on an existing source code and I have some unclear point the stored procedure

For examples:

My_Stored_Procedure_1

CREATE PROC [dbo].[My_Stored_Procedure_1]
    @ID INT,
    @DATE DATETIME
AS
BEGIN
    UPDATE query...
    PRINT 'ID is ' + CAST(@ID AS VARCHAR(10))
END

My_Stored_Procedure_2

CREATE PROC [dbo].[My_Stored_Procedure_2]
   @RESULT INT
AS
BEGIN
   EXEC @RESULT = My_Stored_Procedure_1 // Unclear point
END

My question is that, I don’t see any return value from the My_Stored_Procedure_1, so what will be returned to @RESULT variable? Maybe a default returned value of the executed stored procedure?

Thank you very much.

Answer 1

@Result will have default value that was passed while executing the Stored Procedure My_Stored_Procedure_2.

The statement EXEC @RESULT = My_Stored_Procedure_1 will execute with error and terminate the execution of My_Stored_Procedure_2 because you have not passing two input parameter to My_Stored_Procedure_1 sp while calling this.
