How can I update the foreign keys to make them ON CASCADE UPDATE ?

# EDIT 2 : In order to script out creation or dropping of all foreign keys in your schema run the following script (taken from here) DECLARE @schema_name sysname; DECLARE @table_name sysname; DECLARE @constraint_name sysname; DECLARE @constraint_object_id int; DECLARE @referenced_object_name sysname; DECLARE @is_disabled bit; DECLARE @is_not_for_replication bit; DECLARE @is_not_trusted bit; DECLARE @delete_referential_action tinyint; DECLARE @update_referential_action tinyint; DECLARE @tsql nvarchar(4000); DECLARE @tsql2 nvarchar(4000); DECLARE @fk Col sysname; DECLARE @pk Col sysname; DECLARE @col1 bit; DECLARE @action char(6); DECLARE @referenced_schema_name sysname; DECLARE FKcursor CURSOR FOR select OBJECT_SCHEMA_NAME(parent_object_id) , OBJECT_NAME(parent_object_id), name, OBJECT_NAME(referenced_object_id) , object_id , is_disabled, is_not_for_replication, is_not_trusted , delete_referential_action, update_referential_action, OBJECT_SCHEMA_NAME(referenced_object_id) from sys.foreign_keys order by 1,2; OPEN FKcursor; FETCH NEXT FROM FKcursor INTO @schema_name, @table_name, @constraint_name , @referenced_object_name, @constraint_object_id , @is_disabled, @is_not_for_replication, @is_not_trusted , @delete_referential_action, @update_referential_action, @referenced_schema_name; WHILE @@FETCH_STATUS = 0 BEGIN IF @action 'CREATE' SET @tsql = 'ALTER TABLE ' + QUOTENAME(@schema_name) + '.' + QUOTENAME(@table_name) + ' DROP CONSTRAINT ' + QUOTENAME(@constraint_name) + ';'; ELSE BEGIN SET @tsql = 'ALTER TABLE ' + QUOTENAME(@schema_name) + '.' + QUOTENAME(@table_name) + CASE @is_not_trusted WHEN 0 THEN ' WITH CHECK ' ELSE ' WITH NOCHECK ' END + ' ADD CONSTRAINT ' + QUOTENAME(@constraint_name) + ' FOREIGN KEY ('; SET @tsql2 = ''; DECLARE Column Cursor CURSOR FOR select COL_NAME(fk.parent_object_id, fkc.parent_column_id) , COL_NAME(fk.referenced_object_id, fkc.referenced_column_id) from sys.foreign_keys fk inner join sys.foreign_key_columns fkc on fk.object_id = fkc.constraint_object_id where fkc.constraint_object_id = @constraint_object_id order by fkc.constraint_column_id; OPEN Column Cursor; SET @col1 = 1; FETCH NEXT FROM Column Cursor INTO @fk Col, @pk Col; WHILE @@FETCH_STATUS = 0 BEGIN IF (@col1 = 1) SET @col1 = 0; ELSE BEGIN SET @tsql = @tsql + ','; SET @tsql2 = @tsql2 + ','; END; SET @tsql = @tsql + QUOTENAME(@fk Col); SET @tsql2 = @tsql2 + QUOTENAME(@pk Col); FETCH NEXT FROM Column Cursor INTO @fk Col, @pk Col; END; CLOSE Column Cursor; DEALLOCATE Column Cursor; SET @tsql = @tsql + ' ) REFERENCES ' + QUOTENAME(@referenced_schema_name) + '.' + QUOTENAME(@referenced_object_name) + ' (' + @tsql2 + ')'; SET @tsql = @tsql + ' ON UPDATE ' + CASE @update_referential_action WHEN 0 THEN 'NO ACTION ' WHEN 1 THEN 'CASCADE ' WHEN 2 THEN 'SET NULL ' ELSE 'SET DEFAULT ' END + ' ON DELETE ' + CASE @delete_referential_action WHEN 0 THEN 'NO ACTION ' WHEN 1 THEN 'CASCADE ' WHEN 2 THEN 'SET NULL ' ELSE 'SET DEFAULT ' END + CASE @is_not_for_replication WHEN 1 THEN ' NOT FOR REPLICATION ' ELSE '' END + ';'; END; PRINT @tsql; IF @action = 'CREATE' BEGIN SET @tsql = 'ALTER TABLE ' + QUOTENAME(@schema_name) + '.' + QUOTENAME(@table_name) + CASE @is_disabled WHEN 0 THEN ' CHECK ' ELSE ' NOCHECK ' END + 'CONSTRAINT ' + QUOTENAME(@constraint_name) + ';'; PRINT @tsql; END; FETCH NEXT FROM FKcursor INTO @schema_name, @table_name, @constraint_name , @referenced_object_name, @constraint_object_id , @is_disabled, @is_not_for_replication, @is_not_trusted , @delete_referential_action, @update_referential_action, @referenced_schema_name; END; CLOSE FKcursor; DEALLOCATE FKcursor; constraint, but you want to have that set up, it is a bit of work.

SQL Server does not support altering the constraints to a new setting.

It is necessary to iterate through each table that has a FK constraint to the PK table.

For each table with the FK: This takes a bit of effort, but would result in your constraint being properly set for your case.

EDIT 2: The information that you need is found in sys.foreign_keys.

You can select from that table to get all the information you need.

This page provides an alternate rendering of the Appendix B - Schema Reference from the user's guide.

It spells out in specific detail, just where each attribute or element belongs.
