EXEC sp_fkeys 'TableName'

SELECT
   'ALTER TABLE ['+sch.name+'].['+referencingTable.Name+'] DROP CONSTRAINT ['+foreignKey.name+']' '[DropCommand]'
FROM sys.foreign_key_columns fk
    JOIN sys.tables referencingTable ON fk.parent_object_id = referencingTable.object_id
    JOIN sys.schemas sch ON referencingTable.schema_id = sch.schema_id
    JOIN sys.objects foreignKey ON foreignKey.object_id = fk.constraint_object_id
    JOIN sys.tables referencedTable ON fk.referenced_object_id = referencedTable.object_id

；

SELECT f.name AS 'Name of Foreign Key', OBJECT_NAME(f.parent_object_id) AS 'Table name', COL_NAME(fc.parent_object_id,fc.parent_column_id) AS 'Fieldname', OBJECT_NAME(t.object_id) AS 'References Table name', COL_NAME(t.object_id,fc.referenced_column_id) AS 'References fieldname',

'ALTER TABLE [' + OBJECT_NAME(f.parent_object_id) + '] DROP CONSTRAINT [' + f.name + ']' AS 'Delete foreign key',

'ALTER TABLE [' + OBJECT_NAME(f.parent_object_id) + '] WITH NOCHECK ADD CONSTRAINT [' + f.name + '] FOREIGN KEY([' + COL_NAME(fc.parent_object_id,fc.parent_column_id) + ']) REFERENCES ' + '[' + OBJECT_NAME(t.object_id) + '] ([' + COL_NAME(t.object_id,fc.referenced_column_id) + '])' AS 'Create foreign key' -- , delete_referential_action_desc AS 'UsesCascadeDelete' FROM sys.foreign_keys AS f, sys.foreign_key_columns AS fc, sys.tables t WHERE f.OBJECT_ID = fc.constraint_object_id AND t.OBJECT_ID = fc.referenced_object_id AND OBJECT_NAME(t.object_id) = 'Employees' -- Just show the FKs which reference a particular table ORDER BY 2
