hi,
1. if you run the very same UPDATE manually, does it work?
2. do you have any triggers on these tables? it's possible that they prevent updates from happening.
3. if you have table with same name but in different schema, and specific search_path, this could be a reason too.
We are facing a strange problem in our 8.2.7 database.
There is a bash shell script that does:-
sql=”select distinct to_char(date_of_issue, ‘YYYYMM’) from yan.int_prod_s_master order by 1;”
YYYYMM=`/usr/local/pgsql/bin/psql -U postgres -h payday -d sandbox -t -c “$sql”`
for x in $YYYYMM
do
$scriptdir/USCS_production_updates.sh $x >>$logdir/USCS_production_updates.log 2>&1
done
The $scriptdir/USCS_production_updates.sh script does updates like:-
YYYYMM=$1
database=”us_audit”
db_user=”postgres”
db_host=”nutrageous”
psql_cmd=”/usr/local/pgsql/bin/psql -U ${db_user} -h ${db_host} -d ${database} -e “;
sql=”
update int_prod_manual_price_${YYYYMM} mp
set …
from int_prod_s_master_${YYYYMM} sm
where …
and not exists ( select 1 from int_prod_stop_${YYYYMM} where …)
and …;
“;
$psql_cmd -c “$SQL”
When these scripts run, the USCS_production_updates.log shows the correct update statement, with values of YYYYMM substituted in the table names, and message like “UPDATE 1025” from postgres indicating 1025 rows got updated.
However, none of these updates actually get applied in the database. Auto commit is on in the database, but it seems the updates do not get committed.
The system logs also show no errors.
Any ideas why above update is not working?
