Hi,
I have had a Perl Website working for 7 years and have had no problems
until a few weeks ago I replaced my database server with a newer one.
Database server (old): PostgreSQL 8.4 32bit
Database server (new): PostgreSQL 12.5 64bit
I run following sql in PostgreSQL 8.4 and PostgreSQL 12.5, it returns different
sort results.
--PostgreSQL 8.4
---------------
pg_db=# select ascid from test_order where oo_m.ascid in ('"! ascid"','"001"')
order by ascid;
ascid
-----------
"! ascid"
"001"
(2 rows)
--PostgreSQL 12.5
---------------
pg_db=# select ascid from test_order where oo_m.ascid in ('"! ascid"','"001"')
order by ascid;
ascid
-----------
"001"
"! ascid"
(2 rows)
What is the reason for this and is there any easy way to maintain compatibility?
Regards,
