Most queries you create using OpenESQL Assistant access one table only. If you remove that table from the query, OpenESQL closes the query and you lose the code you've generated for it. However, if you have created a SELECT query that contains one or more table joins, you can safely remove a table without closing the query. When you initiate the removal of a table from a SELECT query, you're prompted to confirm your decision. Upon confirmation, OpenESQL removes the generated code that pertains to the table from the query. It also removes any code pertaining to columns that belong to that table.
