[!INCLUDE[ssNoVersion](../../includes/ssnoversion-md.md)] returns SQL_CASCADE for UPDATE_RULE and/or DELETE_RULE columns if CASCADE option is specified on the ON UPDATE and/or ON DELETE clause of the FOREIGN KEY constraints. [!INCLUDE[ssNoVersion](../../includes/ssnoversion-md.md)] returns SQL_NO_ACTION for UPDATE_RULE and/or DELETE_RULE columns if NO ACTION option is specified on the ON UPDATE and/or ON DELETE clause of the FOREIGN KEY constraints. When invalid values are present in any **SQLForeignKeys** parameter, **SQLForeignKeys** returns SQL_SUCCESS on execution. **SQLFetch** returns SQL_NO_DATA when invalid values are used in these parameters. **SQLForeignKeys** can be executed on a static server cursor. An attempt to execute **SQLForeignKeys** on an updatable (dynamic or keyset) cursor returns SQL_SUCCESS_WITH_INFO indicating that the cursor type has been changed. The [!INCLUDE[ssNoVersion](../../includes/ssnoversion-md.md)] Native Client ODBC driver supports reporting information for tables on linked servers by accepting a two-part name for the *FKCatalogName* and *PKCatalogName* parameters: *Linked_Server_Name.Catalog_Name*. ## See Also [SQLForeignKeys Function](https://go.microsoft.com/fwlink/?LinkId=59344) [ODBC API Implementation Details](odbc-api-implementation-details.md)
