BUG: Oracle Driver Fails to Find Delimited Identifiers

SYMPTOMS

When delimited tablenames are passed to the Oracle driver in an escape clause, the delimiters are removed by the driver. Oracle needs the delimiters to find the table in cases where the table was originally created with the delimiters as part of the tablename. The following error will result when the non-delimited tablenames are passed down: The following query:

   select  "Categories"."Category_Name", "Products"."Product_Name" from
     { oj "Categories" left outer join "Products" on
   "Categories"."Category_ID" = "Products"."Category_ID" }
				

produces the ORA-00942 error. But when the query is formed without using an escape clause, it works:

   select  "Categories"."Category_Name" , "Products"."Product_Name" from
   "Categories" ,"Products" where "Categories"."Category_ID" (+)=
   "Products"."Category_ID"
				

This behavior impacts Access users in that Oracle tables created using the Export function of Access cannot be queried on later when the query involved the Access database engine generating Access SQL queries that involve outer joins.
