>The problem is that my triggers refuse modifying a record if a given Temp table is not created before, because one or more fields have their default values from that temp table
So why don't you either use a normal table, or if you need simultaneous use of the trigger with different values, use an array instead of a table. Or you might create the temp table in the trigger function.. If you create a normal table you can still delete it afterwards. hth WBL -- "Patriotism is the conviction that your country is superior to all others because you were born in it." -- George Bernard Shaw
