Hier ist ein Code, den ich geschrieben habe, um nicht vertrauenswürdige Einschränkungen in einer Datenbank zu identifizieren und zu korrigieren. Es generiert den Code zur Behebung jedes Problems.
;WITH Untrusted (ConstraintType, ConstraintName, ConstraintTable, ParentTable, IsDisabled, IsNotForReplication, IsNotTrusted, RowIndex) AS
(
SELECT
'Untrusted FOREIGN KEY' AS FKType
, fk.name AS FKName
, OBJECT_NAME( fk.parent_object_id) AS FKTableName
, OBJECT_NAME( fk.referenced_object_id) AS PKTableName
, fk.is_disabled
, fk.is_not_for_replication
, fk.is_not_trusted
, ROW_NUMBER() OVER (ORDER BY OBJECT_NAME( fk.parent_object_id), OBJECT_NAME( fk.referenced_object_id), fk.name) AS RowIndex
FROM
sys.foreign_keys fk
WHERE
is_ms_shipped = 0
AND fk.is_not_trusted = 1
UNION ALL
