- (case when COLUMNPROPERTY( a.id,a.name,'IsIdentity')=1 then '√'else '' end) N'标识',
- (case when (SELECT count(*)
- FROM sysobjects
- WHERE (name in
- (SELECT name
- FROM sysindexes
- WHERE (id = a.id) AND (indid in
- (SELECT indid

- WHERE (id = a.id) AND (colid in
- (SELECT colid
- FROM syscolumns
- WHERE (id = a.id) AND (name = a.name))))))) AND
- (xtype = 'PK'))>0 then '√' else '' end) N'主键',

- isnull(e.text,'') N'默认值',
- isnull(g.[value],'') AS N'字段说明'
- --into ##tx
- FROM syscolumns a left join systypes b
- on a.xtype=b.xusertype
- inner join sysobjects d
- on a.id=d.id and d.xtype='U' and d.name<>'dtproperties'
- left join syscomments e
- on a.cdefault=e.id
- left join sysproperties g
