在做个小项目，需要导出表的字段信息，下面是针对，ms sql导出表字段信息的sql语句：
sql 2000:
Code1
SELECT 2
3
(case when a.colorder=1 then d.name else '' end)表名,4
5
a.colorder 字段序号,6
7
a.name 字段名,8
9
(case when COLUMNPROPERTY( a.id,a.name,'IsIdentity')=1 then '√'else '' end) 标识,10
11
(case when (SELECT count(*)12
13
FROM sysobjects14
15
WHERE (name in16
17
(SELECT name18
19
FROM sysindexes20
21
WHERE (id = a.id) AND (indid in22
23
(SELECT indid24
25
FROM sysindexkeys26
27
WHERE (id = a.id) AND (colid in28
29
(SELECT colid30
31
FROM syscolumns32
33
WHERE (id = a.id) AND (name = a.name))))))) AND34
35
(xtype = 'PK'))>0 then '√' else '' end) 主键,36
37
b.name 类型,38
39
a.length 占用字节数,40
41
COLUMNPROPERTY(a.id,a.name,'PRECISION') as 长度,42
43
isnull(COLUMNPROPERTY(a.id,a.name,'Scale'),0) as 小数位数,44
45
(case when a.isnullable=1 then '√'else '' end) 允许空,46
47
isnull(e.text,'') 默认值,48
49
isnull(g.[value],'') AS 字段说明 50
51
52
FROM syscolumns a left join systypes b 53
54
on a.xtype=b.xusertype55
56
inner join sysobjects d 57
58
on a.id=d.id and d.xtype='U' and d.name<>'dtproperties'59
60
left join syscomments e61
62
on a.cdefault=e.id63
64
left join sysproperties g65
66
on a.id=g.id AND a.colid = g.smallid 67
68
order by a.id,a.colorder69
70
71
72
sql 2oo5:
Code1
SELECT2
(case when a.colorder=1 then d.name else '' end) 表名,3
a.colorder 字段序号,4
a.name 字段名,5
(case when COLUMNPROPERTY( a.id,a.name,'IsIdentity')=1 then '√'else '' end) 标识,6
(case when (SELECT count(*)7
FROM sysobjects8
WHERE (name in9
(SELECT name10
FROM sysindexes11
WHERE (id = a.id) AND (indid in12
(SELECT indid13
FROM sysindexkeys14
WHERE (id = a.id) AND (colid in15
(SELECT colid16
FROM syscolumns17
WHERE (id = a.id) AND (name = a.name))))))) AND18
(xtype = 'PK'))>0 then '√' else '' end) 主键,19
b.name 类型,20
a.length 占用字节数,21
COLUMNPROPERTY(a.id,a.name,'PRECISION') as 长度,22
isnull(COLUMNPROPERTY(a.id,a.name,'Scale'),0) as 小数位数,23
(case when a.isnullable=1 then '√'else '' end) 允许空,24
isnull(e.text,'') 默认值,25
g.[value] AS 字段说明26
27
FROM syscolumns a left join systypes b28
on a.xtype=b.xusertype29
inner join sysobjects d30
on a.id=d.id and d.xtype='U' and d.name<>'dtproperties'31
left join syscomments e32
on a.cdefault=e.id33
left join sys.extended_properties g34
on a.id=g.major_id AND a.colid = g.minor_id35
--WHERE d.[name]='AgentMessage' --你要查看的表名，注释掉，查看当前数据库所有表的字段信息36
order by a.id,a.colorder37
38
copy结果到excel或word，就ok了。相当于数据字典了。
