Sql 系統資訊操作

1 導表的:

SELECT TOP (100) PERCENT
 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 欄位序號,
 a.name AS 欄位名,
 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 = so.name AND so.xtype = 'PK'
     WHERE sc.id = a.id AND sc.colid = a.colid) THEN '√' ELSE '' END AS 主鍵,
 b.name AS 型別,
 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 預設值,
 ISNULL(g.value, '') AS 欄位說明,
 d.crdate AS 建立時間,
 CASE WHEN a.colorder = 1 THEN d .refdate ELSE NULL END AS 更改時間
FROM dbo.syscolumns AS a LEFT OUTER JOIN
dbo.systypes AS b ON a.xtype = b.xusertype INNER JOIN
dbo.sysobjects AS d ON a.id = d.id AND d.xtype = 'U'  AND d.status >= 0 LEFT OUTER JOIN
dbo.syscomments AS e ON a.cdefault = e.id LEFT OUTER JOIN
sys.extended_properties AS g ON a.id = g.major_id AND a.colid = g.minor_id LEFT OUTER JOIN
sys.extended_properties AS f ON d.id = f.major_id AND f.minor_id = 0
ORDER BY d.name, 欄位序號

2\導索引的
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 建立時間,
 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\匯出主\外來鍵\約束\試圖等物件
SELECT DISTINCT
TOP 100 PERCENT o.xtype,
CASE o.xtype WHEN 'X' THEN '擴充套件儲存過程' WHEN 'TR' THEN '觸發器' WHEN 'PK' THEN
'主鍵' WHEN 'F' THEN '外來鍵' WHEN 'C' THEN '約束' WHEN 'V' THEN '檢視' WHEN 'FN'
THEN '函式-標量' WHEN 'IF' THEN '函式-內嵌' WHEN 'TF' THEN '函式-表值' ELSE '儲存過程'
END AS 型別, o.name AS 物件名, o.crdate AS 建立時間, o.refdate AS 更改時間,
c.text AS 宣告語句
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 '擴充套件儲存過程' WHEN 'TR' THEN '觸發器' WHEN
'PK' THEN '主鍵' WHEN 'F' THEN '外來鍵' WHEN 'C' THEN '約束' WHEN 'V' THEN '檢視'
WHEN 'FN' THEN '函式-標量' WHEN 'IF' THEN '函式-內嵌' WHEN 'TF' THEN '函式-表值'
ELSE '儲存過程' END DESC

這是3個都是匯出這個庫中的相應物件,如果想匯出單個表的,需要你自己修改一下
希望對你有幫助
