I have a trigger function that updates a field in the update/insert table which uses a not so simple sql statement to find the value to update with. I am not getting the results I expect. I expect I'm falling into some classic trigger gotcha. The table being updated is for 'bids'; 'bids has a fkey to the parent 'item' table. The first time a 'bid' row is added for a particular 'item', the trigger returns null. Any subsequent 'bids' on an 'item' find that the trigger has been invoked and a correct calc applied for the new rows. If value the trigger should apply is hard coded, all table updates get the hard coded value. So there seems to be some kind of timing issue when the complex sql gets involved. But, why does it work after the first row is added for the 'item'? If I change the trigger to be invoked after insert/update, a '0' value is always inserted...I also don't understand that. -- View this message in context: http://www.nabble.com/Trigger-not-working-as-expected%2C-first-row-gets-a-null-value-tf4238812.html#a12061101 Sent from the PostgreSQL - general mailing list archive at Nabble.com. ---------------------------(end of broadcast)--------------------------- TIP 5: don't forget to increase your free space map settings
