本文主要介紹了三個實用的SQL Server數據庫字典SQL語句，數據庫字典主要包括表結構(分為SQL Server 2000和SQL Server 2005)、索引和主鍵. 外鍵.約束.視圖.函數.存儲過程.觸發器。你可以在查詢分析器、企業管理器中簡單執行後，快速的查出SQL Server 2000及SQL Server 2005的全部數據字典。

CASE WHEN a.colorder = 1 THEN d.refdate ELSE NULL END AS 更改時間
FROM dbo.syscolumns a LEFT OUTER JOIN
dbo.systypes b ON a.xtype = b.xusertype INNER JOIN

f.name = 'MS_Description'
ORDER BY d.name, a.colorder

WHEN 1 THEN '降序' WHEN 0 THEN '升序' END AS 排序, CASE WHEN p.id IS NULL
THEN '' ELSE '√' END AS 主鍵, CASE INDEXPROPERTY(c.id, a.name, 'IsClustered')
WHEN 1 THEN '√' WHEN 0 THEN '' END AS 聚集, CASE INDEXPROPERTY(c.id,
a.name, 'IsUnique') WHEN 1 THEN '√' WHEN 0 THEN '' END AS 唯一,
CASE WHEN e.id IS NULL THEN '' ELSE '√' END AS 唯一約束,
a.OrigFillFactor AS 填充因子, c.crdate AS 創建時間, c.refdate AS 更改時間
FROM dbo.sysindexes a INNER JOIN

N'IsMSShipped') = 0) AND (INDEXPROPERTY(a.id, a.name, 'IsAutoStatistics') = 0)
ORDER BY c.name, a.name, b.keyno
3.SQL Server數據庫字典（主鍵.外鍵.約束.視圖.函數.存儲過程.觸發器.sql）
以下為引用的內容：
SELECT DISTINCT
TOP 100 PERCENT o.xtype,
CASE o.xtype WHEN 'X' THEN '擴展存儲過程' WHEN 'TR' THEN '觸發器' WHEN 'PK' THEN
'主鍵' WHEN 'F' THEN '外鍵' WHEN 'C' THEN '約束' WHEN 'V' THEN '視圖' WHEN 'FN'
