I've finally gotten around to this. It doesn't appear to be
possible using a placeholder.
$list # a string of an unknown number of CS numeric primary keys.
$sql = "insert into table2
(col2, col3, ...)
select col2, col3, ...
from table1
where id in (?)";
$sth = $dbh->prepare($sql);
$sth->execute($list) || die ...
This inserts only the first item from $list.
$sth->execute(2,4) complains about mismatched number of bind variables.
An array (@list) does the same thing (only worse:)
where id in ($list)" returns an SQL syntax error.
Should I just fall back or am I missing something?
foreach $item (@list) {
$sql = "insert into table2 ...
Thanks,
Jon
