如何得到数据库中所有表字段及字段中文描述 以下资料,通过csdn的一位师兄从SQL版主那得到: sql中 SELECT (case when a.colorder=1 then d.name else '' end) N'表名', a.colorder N'字段序号', a.name N'字段名', (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 FROM sysindexkeys 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', b.name N'类型', a.length N'占用字节数', COLUMNPROPERTY(a.id,a.name,'PRECISION') as N'长度', isnull(COLUMNPROPERTY(a.id,a.name,'Scale'),0) as N'小数位数', (case when a.isnullable=1 then '√'else '' end) N'允许空', 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 on a.id=g.id AND a.colid = g.smallid order by object_name(a.id),a.colorder
一个字,爽,还可以省去做DD时的好多麻烦. 如果不是很明白,可以将以上代码放到SQL查询分析器上运行一下就知道了(当然要打开一个数据库啦)
