in reply to Dynamic Query construct based on argument

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

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.
