When working with Oracle Locator Spatial there are a lot of cases that require an alias on a table. This works really well in the "select" statement of the Oracle reader but it limits the update of column names unless the select clause is updated as well. It would be an awesome enhancement to add in an alias option to the where. The table name is not allowed unless you add the where as an alias.
i.e. in the where clause allow
a.shape.sdo_gtype = 4402
