sql-server - PK/FKではないSQLServerのすべての制約を一覧表示します

Question

明らかな主キー/外部キーの制約に加えて、データベース内のすべての制約のリストを取得する簡単な方法はありますか？

Answer 1

SQL Server 2005+を想定しています（SQL Serverのバージョンを指定するのに常に役立ちます！）：

SELECT 
  [constraint] = name, 
  [object] = QUOTENAME(OBJECT_SCHEMA_NAME(parent_object_id))
    + '.' + QUOTENAME(OBJECT_NAME(parent_object_id)),
  [definition]
FROM sys.check_constraints
ORDER BY [object], name;

SELECT 
  [constraint] = name,
  [object] = QUOTENAME(OBJECT_SCHEMA_NAME(parent_object_id))
    + '.' + QUOTENAME(OBJECT_NAME(parent_object_id)),
  [definition]
FROM sys.default_constraints
ORDER BY [object], name;

それらを単一の結果セットに結合する場合：

SELECT 
  [constraint] = name, 
  type_desc,
  [object] = QUOTENAME(OBJECT_SCHEMA_NAME(parent_object_id))
    + '.' + QUOTENAME(OBJECT_NAME(parent_object_id)),
  [definition]
FROM sys.check_constraints
UNION ALL
SELECT 
  [constraint] = name,
  type_desc,
  [object] = QUOTENAME(OBJECT_SCHEMA_NAME(parent_object_id))
    + '.' + QUOTENAME(OBJECT_NAME(parent_object_id)),
  [definition]
FROM sys.default_constraints
ORDER BY [object], name;
