This variable is used to specify a table type (TABLE, VIEW, and so forth) that should be looked for when selecting a database table. Using A_ODBC_TABLE_TYPES with other variables, such as USER_PATH and A_ODBC_CATALOG, can speed up the finding of tables in large databases.
This information is passed to the API function call SQLTables() as the TableType parameter. Please refer to your driver’s documentation for supported types.
for example:
A_ODBC_TABLE_TYPES TABLE,VIEW
