Hi all
I have two stored procedures which return dynamic columns as result sets.
is there any way to combine both resultsets???????
after searching for solution i got to know that it is possible when stored procedure returns static columns by using table variable...but what about dynamic columns???????
Thanks

create temporary tables using dynamic query base on the resultset. Temporary tables are accessible in another SP and from that SP, you can join the two tables.

Sorry mate but You can not use temporary tables in other SP.

sorry for the confusion. What i mean is even if they are on different SP, as long as they are within the session. It is possible to access the temporary tables.

Try to store the resultset of your SP in a temporary table. then using the query below, you can identify the columns of the resultset of your two SP's

here is the query:

select * from tempdb.dbo.syscolumns a inner join tempdb.dbo.sysobjects b on a.id = b.id

where b.name like '%#TEMP_TABLE%'

Fetch all the columns and do some logic to create dynamic sql to build your tables.

Now you have the tables. Insert the data from the resultset of the two SP and join the tables.

I Hope you understand my explanation 🙂

If you know what the columns will be you can insert the results of each proc into a table assuming the columns are the same in both procs. I have a feeling that the number and datatypes of columns are not consistent from these two procs. If that is the case you are out of luck. As has been said in this thread and the other duplicate thread, you need to provide some details about what you are trying to do.
