You need to make sure that these "temporary" selects are not returning results sets because - as you've already read - iBATIS does not support multiple result sets.
The best way to debug would be to run the SP from something like Squirrel SQL where you can see the results - and make sure that only one result set is coming back.
If the DB is SQL Server, then the "temporary" selects can be avoided by doing something like "select ... into #temp ...". With DB2 you have more explicit control over which queries generate returned result sets.

Hi all,
I have a problem in getting the resultsets from procedure:
basically a few sqls are run before executing main select sql with in the
procedure.
when i execute i will get uncategorized exception. if i comment first sql
and give hard coded value in second sql it works
I suspect it will try to map resultsets of first sql to resultMap object.
And i have read at this point Ibatis doesnt support multiple resultsets,
In my procedure there are lot of temporary select/update/insert sqls are
executed before main sql will be executed.. in that case
how does IBATIS treat those sql and how do i hide those... and how do i
get resultsets from the last select sql?
Following is the sample code where few temporary queries are executed
before the main select sql.
Pls help in this regard:
Thanks
