in reply to generate self join sql with specified depth level

I've done this at least a couple of times, it's not rocket science.

Something along the lines of...

my $number_of_levels = 5; my $query = 'T1.name AS lev1'; my $join = ''; my $old_table = 'T1'; for(2..$number_of_levels) { $query .= ", T$_.name AS lev$_"; $join .= " LEFT JOIN tab AS T$_ ON T$_.parentID = $old_table.ID"; $old_table = "T$_"; } print $finished_query = "SELECT $query FROM tag AS T1 $join WHERE T1.p +arentID = 0";
That should pretty much do it.
