用sql 查询分析器查询表的字段类型长度和表说明

SELECT sysobjects.name AS 表名, syscolumns.name AS 列名, 
systypes.name AS 数据类型, syscolumns.length AS 数据长度, CONVERT(char, 
sysproperties.[value]) AS 注释
FROM sysproperties RIGHT OUTER JOIN
sysobjects INNER JOIN
syscolumns ON sysobjects.id = syscolumns.id INNER JOIN
systypes ON syscolumns.xtype = systypes.xtype ON 
sysproperties.id = syscolumns.id AND 
sysproperties.smallid = syscolumns.colid
WHERE (sysobjects.xtype = 'u' OR
sysobjects.xtype = 'v') AND (systypes.name <> 'sysname')
--and CONVERT(char,sysproperties.[value]) <> 'null' --导出注释不为'null'的记录
--AND (sysobjects.name = 'bbs_bank_log') --逐个关联表名，可以用or连接条件
ORDER BY 表名
