Re: [GENERAL] Alias-Error - Mailing list pgsql-sql

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
