------导出表结构语句
1、执行以下查询
SELECT 表名称 = case when a.colorder=1 then d.name else '' end, 表说明 = case when a.colorder=1 then isnull(f.value,'') else '' end, 序号 = a.colorder, 列名 = a.name, 中文备注 = isnull(g.[value],''), 数据类型 = b.name, 长度 = COLUMNPROPERTY(a.id,a.name,'PRECISION'), 小数位数 = isnull(COLUMNPROPERTY(a.id,a.name,'Scale'),0), 标识 = case when COLUMNPROPERTY( a.id,a.name,'IsIdentity')=1 then '√'else '' end, 主键 = case when exists(SELECT 1 FROM sysobjects where xtype='PK' and parent_obj=a.id and name in ( SELECT name FROM sysindexes WHERE indid in( SELECT indid FROM sysindexkeys WHERE id = a.id AND colid=a.colid))) then '是' else '否' end, 占用字节数 = a.length, 允许空 = case when a.isnullable=1 then '是'else '否' end, 默认值 = isnull(e.text,'')FROM syscolumns aleft join systypes bon a.xusertype=b.xusertypeinner join sysobjects don a.id=d.id and d.xtype='U' and d.name<>'dtproperties'left join syscomments eon a.cdefault=e.idleft joinsys.extended_properties gon a.id=G.major_id and a.colid=g.minor_idleft joinsys.extended_properties fon d.id=f.major_id and f.minor_id=0 where d.name='TableName' --如果只查询指定表,加上此条件order by a.id,a.colorder
