今日
整顿
材料时看到有这样一个
查问数据库中的表和字段信息的语句，很强! 便是忘了当初谁写的了，印像中该是邹建所创 。也贴出来以后备用吧 。
1SELECT
2表名= CASE a.colorder WHEN 1 THEN c.name ELSE '' END,
3序= a.colorder,
4字段名 = a.name,
5标识= CASE COLUMNPROPERTY(a.id,a.name,'IsIdentity') WHEN 1 THEN '√' ELSE '' END,
6主键= CASE
7WHEN EXISTS (
8SELECT *
9FROM sysobjects
10WHERE xtype='PK' AND name IN (
11SELECT name
12FROM sysindexes
13WHERE id=a.id AND indid IN (
14SELECT indid
15FROM sysindexkeys
16WHERE id=a.id AND colid IN (
17SELECT colid
18FROM syscolumns
19WHERE id=a.id AND name=a.name
20)
21)
22)
23)
24THEN '√'
25ELSE ''
26END,
27类型= b.name,
28字节数 = a.length,
29长度= COLUMNPROPERTY(a.id,a.name,'Precision'),
30小数= CASE ISNULL(COLUMNPROPERTY(a.id,a.name,'Scale'),0)
31WHEN 0 THEN ''
32ELSE CAST(COLUMNPROPERTY(a.id,a.name,'Scale') AS VARCHAR)
33END,
34同意空 = CASE a.isnullable WHEN 1 THEN '√' ELSE '' END,
35默许值 = ISNULL(d.[text],''),
36
注明= ISNULL(e.[value],'')
37FROM syscolumns a
38LEFTJOIN systypesb ON a.xtype=b.xusertype
39INNER JOIN sysobjectsc ON a.id=c.id AND c.xtype='U' AND c.name<>'dtproperties'
40LEFTJOIN syscommentsd ON a.cdefault=d.id
41LEFTJOIN sysproperties e ON a.id=e.id AND a.colid=e.smallid
42ORDER BY c.name, a.colorder
我
批改一下，变个精简版本的：
1
2select a.name, b.xtype,b.name
3from syscolumns a
4innerJOIN systypesb
5ON a.xtype=b.xusertype
6inner join sysobjects c ON
7a.id=c.id AND c.xtype='U' AND c.name<>'dtproperties' where c.name = 表名
