Hi,
I'm trying to write a plperl function to copy the new row e.g. NEW in
plpgsql into another table. I was looking for a similar effect to the
INSERT INTO blah VALUES (NEW.*)
Syntax that can be used in plpgsql. So fat the best I have come up with
is:
$collist = "";
$vallist = "";
while (($col, $val) = each(%{$_TD->{new}}))
{
$collist .= ($col.",");
#Need to fix issues here with quoting in the value list.
$vallist .= ("'".$val."',");
}
chop($collist);
chop($vallist);
However, this leads to issues with numerical columns being quoted, and
worse still NULL numerical column being entered as '' which results in
"Invalid syntax for integer" errors.
The only solution I can see at present is to look up the type of each
column name in the pg_catalog tables, and based upon this, quote as
necessary.
Does anyone have any better suggestions of how to approach this problem?
Many thanks
Chris
