显示某个Sql Server某个数据库中所有表或视图的信息
sql server 2000 与 2005 不同 差别在于 红色字部分
以下语句为获取所有表信息，替换绿色黑体字"U"为"V"为获取所有视图信息。

Sql Server 2000 版本

SELECT Sysobjects.name AS TABLE_NAME, syscolumns.Id, syscolumns.name AS COLUMN_NAME,
systypes.name AS DATA_TYPE, syscolumns.length as CHARACTER_MAXIMUM_LENGTH,
sysproperties.[value] AS COLUMN_DESCRIPTION,  syscomments.text as
COLUMN_DEFAULT,syscolumns.isnullable as IS_NULLABLE FROM syscolumns
INNER JOIN systypes
    ON syscolumns.xtype = systypes.xtype
    LEFT JOIN sysobjects ON syscolumns.id = sysobjects.id
   LEFT OUTER JOIN sysproperties ON
   ( sysproperties.smallid = syscolumns.colid
     AND sysproperties.id = syscolumns.id)
   LEFT OUTER JOIN syscomments ON syscolumns.cdefault = syscomments.id
   WHERE syscolumns.id IN 
    (SELECT id FROM SYSOBJECTS WHERE xtype = 'U') AND (systypes.name <> 'sysname')
    ORDER BY syscolumns.colid

Sql Server 2005版本
