获取sql数据库所有表结构

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 sysobjectsWHERE (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'FROM; syscolumns; a left join systypes b on; a.xtype=b.xusertypeinner join sysobjects d on a.id=d.id; and; d.xtype='U' and; d.name<>'dtproperties'left join syscomments eon a.cdefault=e.idleft join sysproperties gon a.id=g.id AND a.colid = g.smallid; order by object_name(a.id),a.colorder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)
