Hi!
When the following rule is created:
CREATE RULE rule1 AS ON UPDATE TO table1
DO UPDATE table2 SET column7=130 WHERE
column10=NEW.column10
AND column1=(SELECT column1 FROM table3 WHERE column10=NEW.column10 AND column4='N'AND column5=NEW.column1)
AND column6='2'
AND column8=OLD.column7 AND column9=OLD.column2;
then postgresql seems to be confused by the following
SQL such that psql keeps waiting for postgresql's
result:
update table1 set column6=130 where column2=1;
I have to ctrl-c psql to wake up psql.
However, the following rule works without problem:
CREATE RULE rule1 AS ON UPDATE TO table1
DO UPDATE table2 SET column7=130 WHERE
column10=NEW.column10
AND column1='OneConstant' AND column6='2'
AND column8=OLD.column7 AND column9=OLD.column2;
The following SQL also works fine:
update table2 set column7=130 where column10='1'
and column1=(SELECT column1 FROM table3 WHERE
column10='1' AND column4='N' AND column5='ID1') and column6='2' and column8='r'
and column9=1;
Does rule has problem with subselect or the above
problematic rule has bug?
Regards,
cn
