Ok. The exact error message is as follows:
SQLException Time : Mon Oct 20 13:15:25 CEST 2003
SQLException ErrorCode : 0
SQLException SQLState : null
SQLException Message : ERROR: Relation "c2" does not exist
SQLException Connection: 4878867
The query is something like this:
SELECT DISTINCT C2.cmc_mchap, C2.cmc_sort
FROM sis_cmca, sis_cmca C2
WHERE cm_status != 'U' AND sis_cmca.cmc_name='INTERN2000' AND
C2.cmc_name='INTERN2000' AND sis_cmca.cmc_mchap=C2.cmc_mchap
