列出SQL Server上所有用户表的信息

包含表名、字段序号、字段名、标识、主键、类型、占用字节数、长度、小数位数、允许空、默认值和字段说明

直接将下面的内容复制到“查询分析器”执行,可将结果导出为.csv格式。
 
SELECT

       (case when a.colorder=1 then d.name else '' end)表名,

       a.colorder 字段序号,

       a.name 字段名,

       (case when COLUMNPROPERTY( a.id,a.name,'IsIdentity')=1 then '√'else '' end) 标识,

       (case when (SELECT count(*)

       FROM sysobjects

       WHERE (name in

                 (SELECT name

                FROM sysindexes

              (xtype = 'PK'))>0 then '√' else '' end) 主键,

       b.name 类型,

       a.length 占用字节数,

       COLUMNPROPERTY(a.id,a.name,'PRECISION') as 长度,

       isnull(COLUMNPROPERTY(a.id,a.name,'Scale'),0) as 小数位数,

       (case when a.isnullable=1 then '√'else '' end) 允许空,

       isnull(e.text,'') 默认值,

       isnull(g.[value],'') AS 字段说明
