Hi,
I am running a query with alias (a self join) against
version 7.3.4 on Suse Linux 7.3 and on FreeBSD (v5?).
It runs fine on Linux, but produces an error on
FreeBSD: "unknown alias C2". And btw: the query runs
on every other DB I have tried...
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
....
What causes this error? Workarounds?
Jost

The string "unknown alias" appears nowhere in the 7.3 sources.
Are you sure you are talking to a Postgres database?

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

^^^^^^^^^
You're missing a table name here. It could be PG is reporting the wrong error.

You have the alias in upper case: "C2", and postgres complains about a
lower case "c2". May be this some case sensitivity problem ?
Just a thought.
HTH,
Csaba.
