sql查询表结构，过程，视图，主键，外键，约束_数据库

一、表结构查询

SELECT TOP (100) PERCENT a.name AS zdm,COLUMNPROPERTY(a.id, a.name, 'IsIdentity') AS bs ,
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 '1' ELSE '0' END AS zj , b.name AS lx, a.length AS cd, COLUMNPROPERTY(a.id, a.name,'PRECISION')
 AS jd, ISNULL(COLUMNPROPERTY(a.id, a.name, 'Scale'), 0) AS xsws,a.isnullable AS yxk, ISNULL(e.text, '')
  AS mrz, ISNULL(g.value, '') AS zdsm 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  where d .name='查询的表名'

二、
-- 查询存储过程
select CASE a.xtype  WHEN 'p' THEN '存储过程' end as lx ,a.name, b.text from sysobjects a left outer join syscomments b on a.id = b.id where xtype='p'
--查询视图
select  CASE a.xtype  WHEN 'v' THEN '视图' end as lx,a.name , b.text from sysobjects a left outer join syscomments b on a.id = b.id where xtype='v'

--主键，外键，约束
select
CASE a.xtype  WHEN 'PK' THEN '主键' WHEN 'F' THEN '外键' WHEN 'C' THEN '约束'
END AS lx,a.name AS name,
b.text from sysobjects a left outer join syscomments b on a.id = b.id
where (a.xtype IN ( 'C',  'F','PK')) AND
(OBJECTPROPERTY(a.id, N'IsMSShipped') = 0) and a.parent_obj=(select id from sysobjects where name = 'table_2')

环境是用的sql2008

其中涉及到的表  与视图  过程的名称在帮助中能够查到
