Question

I am using Sybase DB with TSQL.

I am trying to work between 2 SPROCS, one nested inside the other.

My outer SPROC will create a temp table #temp_table and fill it up with values to 200. Once the temp table has been populated with 200 entries, it will be used by the inner SPROC for a JOIN.

So essentially, my outer SPROC will have the following (simplified):

CREATE TABLE #temp_table 
(
  ... columns ...
)

and my inner SPROC will have the following:

SELECT
  SOME_COLUMNS
FROM
  SOME_TABLE
INNER JOIN
  #temp_table
ON
  SOME_CONDITION

When I try to test this, I run the script for my inner SPROC and it complains of #temp_table not existing, and fails to create the SPROC in the DB. So when I try to go run my outer SPROC, it will also fail.

Could I please get some pointers on how to solve this problem?

Don’t do it in two stored procedures. Do it all in one. A single stored procedure can have as many SQL statements as you need to get the job done, and a temp table is only available within the context of the stored procedure where it’s created.

CREATE PROC DoItAll
AS

   CREATE TABLE #temp_table 
   (
     ... columns ...
   );

   SELECT
     SOME_COLUMNS
   FROM
     SOME_TABLE
   INNER JOIN
     #temp_table
   ON
     SOME_CONDITION;
