SQL Server數據庫字典SQL語句

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后，快速的查出SQL Server 2000及SQL Server 2005的全部數據字典。
1. SQL Server 2000數據庫字典（表結構.sql）

SELECT TOP 100 PERCENT --a.id, CASE WHEN a.colorder = 1 THEN d.name ELSE '' END AS 表名, CASE WHEN a.colorder = 1 THEN isnull(f.value, '') ELSE '' END AS 表說明, a.colorder AS 字段序號, a.name AS 字段名, CASE WHEN COLUMNPROPERTY(a.id, a.name, 'IsIdentity') = 1 THEN '√' ELSE '' END AS 標識, CASE WHEN EXISTS (SELECT 1 FROM dbo.sysindexes si INNER JOIN dbo.sysindexkeys sik ON si.id = sik.id AND si.indid = sik.indid INNER JOIN dbo.syscolumns sc ON sc.id = sik.id AND sc.colid = sik.colid INNER JOIN dbo.sysobjects so ON so.name = si.name AND so.xtype = 'PK' WHERE sc.id = a.id AND sc.colid = a.colid) THEN '√' ELSE '' END AS 主鍵, b.name AS 類型, a.length AS 長度, COLUMNPROPERTY(a.id, a.name, 'PRECISION') AS 精度, ISNULL(COLUMNPROPERTY(a.id, a.name, 'Scale'), 0) AS 小數位數, CASE WHEN a.isnullable = 1 THEN '√' ELSE '' END AS 允許空, ISNULL(e.text, '') AS 默認值, ISNULL(g.[value], '') AS 字段說明, d.crdate AS 創建時間, 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 dbo.sysobjects d ON a.id = d.id AND d.xtype = 'U' AND d.status >= 0 LEFT OUTER JOIN dbo.syscomments e ON a.cdefault = e.id LEFT OUTER JOIN dbo.sysproperties g ON a.id = g.id AND a.colid = g.smallid AND g.name = 'MS_Description' LEFT OUTER JOIN dbo.sysproperties f ON d.id = f.id AND f.smallid = 0 AND f.name = 'MS_Description' ORDER BY d.name, a.colorder

◆SQL Server 2005數據庫字典（表結構.sql） 

SELECT TOP 100 PERCENT --a.id, CASE WHEN a.colorder = 1 THEN d.name ELSE '' END AS 表名, CASE WHEN a.colorder = 1 THEN isnull(f.value, '') ELSE '' END AS 表說明, a.colorder AS 字段序號, a.name AS 字段名, CASE WHEN COLUMNPROPERTY(a.id, a.name, 'IsIdentity') = 1 THEN '√' ELSE '' END AS 標識, CASE WHEN EXISTS (SELECT 1 FROM dbo.sysindexes si INNER JOIN dbo.sysindexkeys sik ON si.id = sik.id AND si.indid = sik.indid INNER JOIN dbo.syscolumns sc ON sc.id = sik.id AND sc.colid = sik.colid INNER JOIN dbo.sysobjects so ON so.name = si.name AND so.xtype = 'PK' WHERE sc.id = a.id AND sc.colid = a.colid) THEN '√' ELSE '' END AS 主鍵, b.name AS 類型, a.length AS 長度, COLUMNPROPERTY(a.id, a.name, 'PRECISION') AS 精度, ISNULL(COLUMNPROPERTY(a.id, a.name, 'Scale'), 0) AS 小數位數, CASE WHEN a.isnullable = 1 THEN '√' ELSE '' END AS 允許空, ISNULL(e.text, '') AS 默認值, ISNULL(g.[value], '') AS 字段說明, d.crdate AS 創建時間, 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 dbo.sysobjects d ON a.id = d.id AND d.xtype = 'U' AND d.status >= 0 LEFT OUTER JOIN dbo.syscomments e ON a.cdefault = e.id LEFT OUTER JOIN dbo.sysproperties g ON a.id = g.id AND a.colid = g.smallid AND g.name = 'MS_Description' LEFT OUTER JOIN dbo.sysproperties f ON d.id = f.id AND f.smallid = 0 AND f.name = 'MS_Description' ORDER BY d.name, a.colorder

2.SQL Server數據庫字典（索引.sql）

SELECT TOP 100 PERCENT --a.id, CASE WHEN b.keyno = 1 THEN c.name ELSE '' END AS 表名, CASE WHEN b.keyno = 1 THEN a.name ELSE '' END AS 索引名稱, d.name AS 列名, b.keyno AS 索引順序, CASE indexkey_property(c.id, b.indid, b.keyno, 'isdescending') 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 dbo.sysindexkeys b ON a.id = b.id AND a.indid = b.indid INNER JOIN dbo.syscolumns d ON b.id = d.id AND b.colid = d.colid INNER JOIN dbo.sysobjects c ON a.id = c.id AND c.xtype = 'U' LEFT OUTER JOIN dbo.sysobjects e ON e.name = a.name AND e.xtype = 'UQ' LEFT OUTER JOIN dbo.sysobjects p ON p.name = a.name AND p.xtype = 'PK' WHERE (OBJECTPROPERTY(a.id, N'IsUserTable') = 1) AND (OBJECTPROPERTY(a.id, 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）

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' THEN '函數-標量' WHEN 'IF' THEN '函數-內嵌' WHEN 'TF' THEN '函數-表值' ELSE '存儲過程' END AS 類型, o.name AS 對象名, o.crdate AS 創建時間, o.refdate AS 更改時間, c.text AS 聲明語句 FROM dbo.sysobjects o LEFT OUTER JOIN dbo.syscomments c ON o.id = c.id WHERE (o.xtype IN ('X', 'TR', 'C', 'V', 'F', 'IF', 'TF', 'FN', 'P', 'PK')) AND (OBJECTPROPERTY(o.id, N'IsMSShipped') = 0) ORDER BY 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' THEN '函數-標量' WHEN 'IF' THEN '函數-內嵌' WHEN 'TF' THEN '函數-表值' ELSE '存儲過程' END DESC
