Description: Catalog Location

Indicates the position of the catalog name in a qualified table name in a text command. One of the following:

• DBPROPVAL_CL_START—The catalog name is at the start of the fully qualified name. For example, a dBASE^® provider returns DBPROPVAL_CL_START because the directory (catalog name) is at the start of the table name—for example, "\EMPDATA\Emp.dbf".
  
  
• DBPROPVAL_CL_END—The catalog name is at the end of the fully qualified name. For example, an Oracle^® server provider returns DBPROPVAL_CL_END because the catalog name is at the end of the table name, as in "mailto: ADMIN.EMP@EMPDATA".
