To disable the use of SQL bind variables add DisableBind=1 to DBPARM
e.g.
  SQLCA.DBParm = "DisableBind=1," + "ConnectString='DSN=MyData;UID=DBA;PWD=SQL'"

This will remove the ? in select statements and show the true value which is better for debugging
Bind variables are supposed to be faster, so you may wish to enable them after development.
