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

The way you have it should work i.e. if the NEW array has a field called
duser in it you will be able to access it using $NEW(duser)
Put in an elog notice and do [array names NEW] in it.
Run the function and see what variables are available to you then you
should be able to call them just like shown below
-bash-2.05b$ tclsh
% set NEW(duser) darren
darren
% set NEW(cuser) carl
carl
% foreach id [array names NEW] { puts $NEW($id) }
carl
darren
% puts $NEW(duser)
darren
% puts $NEW(cuser)
carl

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 everyone,
I have an ArrayList whose members are classes. These classes are derived from a same base class. The base class has a floating point array and a string. How do I access each element in the floating point array in a member of the ArrayList?
Any help would be greatly appreciated.

Hello all,
Is there anyway to store an array to MS Access 2002 without parsing the
entire array row-by-row. For example, Oracle allows you to store BLOBs
(binary large objects). I would like to be able to say in VB/VBA
With rstName

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
