Re: Trigger with dynamic SQL - Mailing list pgsql-admin

Sorry for the inconvenience, but no one have ideas to solve this problem? Am I in the wrong list to ask this?
Need I create triggers for each table?

Thanks in advance for any suggestions.

To avoid to delete registers I created one trigger activated "before delete" with lines like that:
UPDATE tableX  set dtExc = 'now', userExc = current_user where idTableX = OLD.idTableX;
return NULL;

but, I need do the same for many tables and I don't catch how.
I created an sql variable to construct the update command using parameters on trigger
      qry := 'UPDATE '||arg_table||' set userexc = ' ||chr(39)||current_user||chr(39)||', dtalt = '||'''now'''||' where ' || arg_id ||' = OLD.'||TG_ARGV[1];

but when "EXECUTE qry" I lost the OLD.variable.

I can't send the bigint id to delete in trigger parameters.

Any suggestions?

Thanks in advance,
