Hi Experts,
1)Is it possible to call a Stored procedure from a SQL query?
2)Is it possible to combine the result of two Stored Procedures that returns result of select statements ?
If so can you give me some examples..
Regards,

To execute a stored procedure, use the syntax below:

exec storedprocedurename parameterlist

For example, if my stored procedure name was usp_GetSalesByState with a parameter of StateID, I would use:

exec usp_GetSalesByState 'GA'

OR

execute usp_GetSalesByState 'GA'

As for joining the results of 2 stored procedures, you may need to clarify. You can return more than 1 result set from a stored procedure. You may also use a union/union all operation within a stored procedure to join 2 data sets. You can also write the results of 2 stored procedures to temporary tables and then union those tables -- all within a 3rd stored procedure.

I hope that this helps. Thanks.

Kind of:

...INSERT INTO...EXEC...

The target table columns must match the output of the stored procedure - sequence and datatype.

INSERT INTO #Table1 EXEC Sproc1

INSERT INTO #Table2 EXEC Sproc2

SELECT t1.*

FROM #Table1 t1

LEFT JOIN #Table2 t2

You can use user defined functions that returns tables and then treat the tables returned from the function as any other table
