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. There should be neither too little or too much, neither needless loops nor useless variables, neither lack of structure nor overwhelming rigidity." - The Tao of Programming, 4.1 - Geoffrey James My blog: Imperial Deltronics	[reply]
