[!INCLUDEssNoVersion] supports cascading updates and deletes through the foreign key constraint mechanism. [!INCLUDEssNoVersion] 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. [!INCLUDEssNoVersion] 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 [!INCLUDEssNoVersion] 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.
