SQLTables
When restricted to the current database, SQLTables executes the Transact-SQL procedure sp_tables to report table catalog data for Microsoft® SQL Server™.
The following table shows SQLTables parameter mapping for sp_tables stored procedure execution.
| SQLTables parameter name | sp_tables parameter name |
|---|---|
| CatalogName | table_qualifier |
| SchemaName | table_owner |
| TableName | table_name |
| TableType | table_type |
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). SQLTables does not make use of sp_tables in this special case.
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 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.
Example
// 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);
