获取SQL SERVER 2000/2005数据库字段属性

SQL SERVER 2000 和 2005结构是不一样的，所以在获取SQL SERVER 2000/2005字段属性时需要分别来获取。

1。SQL SERVER 2000

1

2SELECT

3 字段名 = a.name,

4 主键 = case when exists(SELECT 1 FROM sysobjects where xtype='PK' and parent_obj=a.id and name in (

5 SELECT name FROM sysindexes WHERE indid in(

6 SELECT indid FROM sysindexkeys WHERE id = a.id AND colid=a.colid))) then '1' else '0' end,

7 标识 = CASE WHEN COLUMNPROPERTY(a.id, a.name,

8 'IsIdentity') = 1 THEN '1' ELSE '0' END,

9 类型 = b.name,

10 占用字节数 = a.length,

11 长度 = COLUMNPROPERTY(a.id,a.name,'PRECISION'),

12 小数 = a.xscale,

13 可空 = a.isnullable,

14 默认值 = isnull(e.text,''),

15 字段说明 = isnull(g.[value],'')

16FROM

17 syscolumns a

18left join

19 systypes b

20on

21 a.xusertype=b.xusertype

22inner join

23 sysobjects d

24on

25 a.id=d.id and d.xtype='U' and d.name<>'dtproperties'

26left join

27 syscomments e

28on

29 a.cdefault=e.id

30left join

31 sysproperties g

32on

33 a.id=g.id and a.colid=g.smallid

34left join

35 sysproperties f

36on

37 d.id=f.id and f.smallid=0

38where

39 d.name='UserAccount'
d.name = 'UserAccount'，UserAccount为你需要查找的数据表。

2。SQL SERVER 2005

1SELECT CASE WHEN EXISTS

2 (SELECT 1

3 FROM sysobjects

4 WHERE xtype = 'PK' AND parent_obj = a.id AND name IN

5 (SELECT name

6 FROM sysindexes

7 WHERE indid IN

8 (SELECT indid

9 FROM sysindexkeys

10 WHERE id = a.id AND colid = a.colid))) THEN '1' ELSE '0' END AS 'key', CASE WHEN COLUMNPROPERTY(a.id, a.name,

11 'IsIdentity') = 1 THEN '1' ELSE '0' END AS 'identity', a.name AS ColName, c.name AS TypeName, a.length AS 'byte', COLUMNPROPERTY(a.id, a.name,

12 'PRECISION') AS 'length', a.xscale, a.isnullable, ISNULL(e.text, '') AS 'default', ISNULL(p.value, '') AS 'comment'

13FROM sys.syscolumns AS a INNER JOIN

14 sys.sysobjects AS b ON a.id = b.id INNER JOIN

15 sys.systypes AS c ON a.xtype = c.xtype LEFT OUTER JOIN

16 sys.syscomments AS e ON a.cdefault = e.id LEFT OUTER JOIN

17 sys.extended_properties AS p ON a.id = p.major_id AND a.colid = p.minor_id

18WHERE (b.name = 'keyfactory') AND (c.status <> '1')
b.name = 'Keyfactory','Keyfactory'为你想要查找的数据表。
