# SQLForeignKeys
[!INCLUDE[appliesto-ss-asdb-asdw-pdw-md](../../includes/appliesto-ss-asdb-asdw-pdw-md.md)]

  [!INCLUDE[ssNoVersion](../../includes/ssnoversion-md.md)] supports cascading updates and deletes through the foreign key constraint mechanism. [!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*.
