The following are the schema rowsets that have been changed or added to support table-valued parameters.
| Schema rowset | Description |
|---|---|
| DBSCHEMA_PROCEDURE_PARAMETERS | Two new columns were added at the end of the rowset named SS_TYPE_CATALOG_NAME and SS_TYPE_SCHEMANAME. These columns could be re-used for future types. The TYPE_NAME and LOCAL_TYPE_NAME columns will contain the name of the table-valued parameter TABLE type. The DATA_TYPE column will have value DBTYPE_TABLE = 143 for table-valued parameters. |
| DBSCHEMA_TABLE_TYPES | This rowset was added to support table-valued parameters. It is identical to DBSCHEMA_TABLES, except that it returns metadata only for table types, rather than for tables, views, or synonyms. The TABLE_TYPE column will have the value 'TABLE TYPE'. |
| DBSCHEMA_TABLE_TYPE_PRIMARY_KEYS | This rowset was added to support table-valued parameters. It is identical to DBSCHEMA_PRIMARY_KEYS, except that it returns primary keys metadata only for table types, rather than for tables. |
| DBSCHEMA_TABLE_TYPE_COLUMNS | This rowset was added to support table-valued parameters. It is identical to DBSCHEMA_COLUMNS, except that it returns column metadata only for table types, rather than for tables, views, or synonyms. |
