超级有用的SQL语句 (用于SQL SERVER 服务器)
超级有用的SQL语句 ,执行后返回的列分别是:表名、列名、列类型、列长度、列描述、是否主键,语句如下:
(分析SQL SERVER 数据库表结构专用)
以下是SQLSERVER2000
Select Sysobjects.Name As 表名,
Syscolumns.Name As 列名,
Systypes.Name As 列类型,
Syscolumns.Length As 列长度,
Isnull(Sysproperties.Value, Syscolumns.Name) As 列说明,
Case
When Syscolumns.Name In
(Select 主键 = A.Name
From Syscolumns A
Inner Join Sysobjects B On A.Id = B.Id
And B.Xtype = 'U'
And B.Name <> 'Dtproperties'
Where Exists (Select 1
From Sysobjects
Where Xtype = 'Pk'
And Name In
(Select Name
From Sysindexes
Where Indid In
(Select Indid
From Sysindexkeys
Where Id = A.Id
And Colid = A.Colid)))
And B.Name = Sysobjects.Name) Then
1
Else
0
End As 是否主键
From Sysobjects, Systypes, Syscolumns
Left Join Sysproperties On (Syscolumns.Id = Sysproperties.Id And
Syscolumns.Colid = Sysproperties.Smallid)
Where (Sysobjects.Xtype = 'U' Or Sysobjects.Xtype = 'V')
And Sysobjects.Id = Syscolumns.Id
And Systypes.Xtype = Syscolumns.Xtype
And Systypes.Name <> 'Sysname'
And Sysobjects.Name Like '%'
Order By Sysobjects.Name, Syscolumns.Colid
以下是SQLSERVER 2005版本的语句
选择 Sysobjects.Name 作为表名,
Syscolumns.Name 作为列名,
Systypes.Name 作为列类型,
Syscolumns.Length 作为列长度,
Isnull(sys.extended_properties. Value, Syscolumns.Name) As 列说明,
Case
When Syscolumns.Name In
(选择主键 = A.Name
来自 Syscolumns A
在 A.Id 上内连接 Sysobjects B = B.Id
和 B.Xtype = 'U'
和 B.Name 'Dtproperties'
存在的地方(选择 1
来自 Sysobjects
其中 Xtype = 'Pk'
并输入名称
(选择名称
来自系统索引
Indid 在哪里
(选择 Indid
来自 Sysindexkeys
其中 Id = A.Id
且 Colid = A .Colid)))
且 B.Name = Sysobjects.Name) 然后
1
Else
0
End As 是否主键
来自 Sysobject s、系统类型、系统列
左加入 sys.extended_properties On (Syscolumns.Id = sys.extended_properties.major_id And
Syscolumns.Colid = sys.extended_properties.minor_id)
其中 (Sysobjects.Xtype = 'U' 或 Sysobjects.Xtype =“V”)
且 Sysobjects.Id = Syscolumns.Id
且 Systypes.Xtype = Syscolumns.Xtype
且 Systypes.Name 'Sysname'
和 Sysobjects.Name 类似 'XJY%'
按 Sysobjects.Name、Syscolumns.Colid
