显示 Sql Server 中所有表或表中行的信息

在MSSQL中显示某个数据库中所有表或视图的信息：

（以下语句为获取所有表信息，将绿色字"U"替换为"V"则获取所有视图信息。）

SELECT sysobjects.name AS TABLE_NAME, syscolumns.Id, syscolumns.name AS COLUMN_NAME,
systypes.name AS DATA_TYPE, syscolumns.length as COLUMN_MAX_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 sysobjects.name

上述代码在 Microsoft SQL Server 2012 (SP1) - 11.0.3128.0 (X64) 中经测试可以使用。

对于 Sql Server 2000 版本或 Sql Server 2005版本请参考：显示 Sql Server 中所有表中的信息

可用上述代码筛选获取某个表中的所有行信息：

declare @TableNamePar varchar(50)
set @TableNamePar = 'TableOne'

SELECT sysobjects.name AS TABLE_NAME, syscolumns.Id, syscolumns.name AS COLUMN_NAME,
systypes.name AS DATA_TYPE, syscolumns.length as COLUMN_MAX_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')
AND sysobjects.name = @TableNamePar
order by sysobjects.name

上述代码同样在 Microsoft SQL Server 2012 (SP1) - 11.0.3128.0 (X64) 中经测试可以使用。
