I just changed it into a string reference (e.g. \" = drivers.userid")

But this strategy fails if you want to look for a key field. For example, to obtain the following query:

SELECT drivers.username FROM users, drivers WHERE users.userid=drivers
+.userid AND users.userid=1000

You should do something like:

my($stmt2, @bind2) =
  $sql->select("users, drivers",
               ["drivers.username"],
               { "users.userid" => 1000,
                 "users.userid" => \"= drivers.userid"} # <- Overrides
+ previous "users.userid" key
   );

But you end up with 2 identical keys in the anonymous hash and the second will override the first. Yes, one solution is to swap the (key,value) pair in last hash entry to drivers.userid => \"= users.userid", but for doing that automatically (that's the point for using SQL::Abstract after all) I must check all possible keys in the WHERE clause.

Is there a way to overcome this?

Thanks in advance
