Accessing a temp table from DBUnit - spring

Question

I have a stored procedure in Sybase that returns some data in a temp table (let's call it #results). If I create this table from my own code and call the stored procedure and check the #results everything is fine (I use Python for this purpose). I can generate the expected result set for my test.
However when I try to create a DBUnit test case so that the code
creates the temp table via the Spring JdbcTemplate
calls this procedure and checks the returned data
I get a NoSuchTableException from DbUnit when checking the result set.

Checking the database in parallel with the test code execution (at a breakpoint) I can see that the temp table is indeed created in tempdb and filled with data.
Has anyone done such a thing successfully (eg. used a Sybase temp table from DbUnit)? If yes, how?

Answer 1

If you create temporary tables by using “#” as the first character of the table name:
Temporary tables:
Exist only for the duration of the user session or for the scope of the procedure that creates them
Cannot be shared between user connections
Are automatically dropped at the end of the session or procedure (or can be dropped manually)
You can create regular user tables in tempdb by specifying the database name in the command that creates the table:
Regular user tables in tempdb:
Can persist across sessions
Can be used by bulk copy operations
Can be shared by granting permissions on them
Must be explicitly dropped by the owner (otherwise, they are removed when Adaptive Server is restarted)
