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
SELECT Sysobjects.name AS TABLE_NAME, syscolumns.Id, syscolumns.name AS COLUMN_NAME,
systypes.name AS DATA_TYPE, syscolumns.length as CHARACTER_MAXIMUM_LENGTH,
sys.extended_properties.[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 sys.extended_properties ON
( sys.extended_properties.minor_id = syscolumns.colid
AND sys.extended_properties.major_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
