Returns the list of table, catalog, or schema names stored in a specific data source. The information is returned as a result set.

Input arguments:

• StatementHandle.
• CatalogName. A search pattern is allowed if the SQL_ODBC_VERSION environment attribute is SQL_OV_ODBC3, but not if it is set to SQL_OV_ODBC2. If a driver supports catalogs for some tables but not others, such as when the driver retrieves data from different DBMSs, an empty string ("") denotes tables without catalogs.
• NameLength1. The length of CatalogName.
• SchemaName. A string-search pattern for schema names. If a driver supports schemas for some tables but not others, such as when the driver retrieves data from different DBMSs, an empty string ("") denotes tables without schemas.
• NameLength2. The length of SchemaName.
• TableName. A string-search pattern for table names.
• NameLength3. The length of TableName.
• TableType. The list of table types to match.
• NameLength4. The length of TableType.
