SQLTables

 

SQLTables can be executed on a static server cursor. An attempt to execute SQLTables on an updatable (dynamic or keyset) cursor will return SQL_SUCCESS_WITH_INFO indicating that the cursor type has been changed.

SQLTables reports tables from all databases when the CatalogName parameter is SQL_ALL_CATALOGS and all other parameters contain default values (NULL pointers).

To report available catalogs, schemas, and table types, SQLTables makes special use of empty strings (zero-length byte pointers). Empty strings are not default values (NULL pointers).

The SQL Server Native Client ODBC driver supports reporting information for tables on linked servers by accepting a two-part name for the CatalogName parameter: Linked_Server_Name.Catalog_Name.

SQLTables returns information about any tables whose names match TableName and are owned by the current user.

When the statement attribute SQL_SOPT_SS_NAME_SCOPE has the value SQL_SS_NAME_SCOPE_TABLE_TYPE, rather than its default value of SQL_SS_NAME_SCOPE_TABLE, SQLTables returns information about table types. The TABLE_TYPE value returned for a table type in column 4 of the result set returned by SQLTables is TABLE TYPE. For more information on SQL_SOPT_SS_NAME_SCOPE, see SQLSetStmtAttr.

Tables, views, and synonyms share a common namespace that is distinct from the namespace used by table types. Although it is not possible to have a table and a view with the same name, it is possible to have a table and a table type with the same in the same catalog and schema.

For more information about table-valued parameters, see Table-Valued Parameters (ODBC).

// Get a list of all tables in the current database.
SQLTables(hstmt, NULL, 0, NULL, 0, NULL, 0, NULL,0);

// Get a list of all tables in all databases.
SQLTables(hstmt, (SQLCHAR*) "%", SQL_NTS, NULL, 0, NULL, 0, NULL,0);

// Get a list of databases on the current connection's server.
SQLTables(hstmt, (SQLCHAR*) "%", SQL_NTS, (SQLCHAR*)"", 0, (SQLCHAR*)"",
    0, NULL, 0);
