Well, DBI, Perl's standard way of interfacing with databases, lets you do just that. You can make an SQL statement with parameters that can be set later: `my $dbh = DBI->connect(...connection parameters...); my $get_foo = $dbh->prepare("select foo from table where bar=?"); $get_foo->execute(3); #select foo where bar=3 $get_foo->execute($baz); #select foo where bar=$baz` [download] Perhaps you meant something different by constructing a query. If so, you need to specify what you mean. SQL is a whole programming language in itself. When's the last time you used duct tape on a duct? --Larry Wall	[reply] [d/l]

Perhaps SQL::Abstract can help you. It transforms a Perl data-structure into valid SQL. CountZero A program should be light and agile, its subroutines connected like a string of pearls. The spirit and intent of the program should be retained throughout.
