Hi to all ... I'm looking to a way to auto update some fields of a row when other fileds are updated.
the table structure are simple, CREATE TABLE param ( id int4 PRIMARY KEY, val int4, ts timestam(3) DEFAULT CURRENT_TIMESTAMP ); so when a new entry are insert ts areautomatically update, but i would make the same on update ... i would that on UDPATE param SET val=100 WHERE id=1; also ts field have to be updated to CURRENT_TIMESTAMP I try with a RULE but obtain only a loop, seem RULE aren't good to make such things, modify a statment on the same table it's related :( i look for a trigger but I suppose the same problem arise ... how i can solve the problem ??? mhhh does i have to have a VIEW of parm ... called param2 without the ts field and make a rule on param2 that update param.ts ??? seem a bit tricky :( ... thanks in advance ... -- Alessandro GARDICH <[EMAIL PROTECTED]> gremlin.it ---------------------------(end of broadcast)--------------------------- TIP 8: explain analyze is your friend
