Re: Access to an element of array NEW in TCL

As long as it is an insert or update trigger that fires your tcl
function, you have access to the NEW array. The foreach loop uses the
tcl command [array names NEW] to suck out the names of the existing
members of the array. If a column called duser exists in the NEW array
(it is part of the inserted tuple, or not updated to null) you should be
able to access it as

$NEW(duser)

What error are you getting? If the duser column is null, there is no
array member called NEW(duser) and you will get an error to that effect.

Hi list,

Is there a way to access an especific element of the array NEW in an
TCL trigger, I have a loop that goes for each field (thanks Ian &
Darren) like this:

foreach id [array names NEW] {

then I can refer to an element with this (inside the loop):
$NEW($id)

I do need to make a reference to an especific column name (duser) in
that array to get its value, I already tried $NEW(duser),
$NEW(\'duser\') but didn't work. I'll appreciate any help from you

Thanks

TIP 2: you can get off all lists at once with the unregister command
(send "unregister YourEmailAddressHere" to majordomo@postgresql.org)
