如何用一種很直觀的方式查詢出數據庫中所有表的定義信息以及相關索引信息，針對喜歡中文顯示的童鞋：
SELECT
表名=CASE WHEN C.column_id=1 THEN O.name ELSE N‘‘ END,
表說明=ISNULL(CASE WHEN C.column_id=1 THEN PTB.[value] END,N‘‘),
字段序號=C.column_id,
字段名=C.name,
主鍵=ISNULL(IDX.PrimaryKey,N‘‘),
標識=CASE WHEN C.is_identity=1 THEN N‘√‘ELSE N‘‘ END,
計算列=CASE WHEN C.is_computed=1 THEN N‘√‘ELSE N‘‘ END,
類型=T.name,
長度=C.max_length,
精度=C.precision,
小數位數=C.scale,
允許空=CASE WHEN C.is_nullable=1 THEN N‘√‘ELSE N‘‘ END,
默認值=ISNULL(D.definition,N‘‘),
字段說明=ISNULL(PFD.[value],N‘‘),
