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
