如何在SQL Server中查找所有数据库中所有表的列名

我想在所有数据库的所有表中查找所有列名。有没有一个查询可以帮我做到这一点？数据库是Microsoft SQL Server 2000。

请尝试以下操作：

select 
    o.name,c.name 
    from sys.columns            c
        inner join sys.objects  o on c.object_id=o.object_id
    order by o.name,c.column_id

对于生成的列名，这将是：

select 
     o.name as [Table], c.name as [Column]
     from sys.columns            c
         inner join sys.objects  o on c.object_id=o.object_id
     --where c.name = 'column you want to find'
     order by o.name,c.name

或了解更多详细信息：

SELECT
    s.name as ColumnName
        ,sh.name+'.'+o.name AS ObjectName
        ,o.type_desc AS ObjectType
        ,CASE
             WHEN t.name IN ('char','varchar') THEN t.name+'('+CASE WHEN s.max_length<0 then 'MAX' ELSE CONVERT(varchar(10),s.max_length) END+')'
             WHEN t.name IN ('nvarchar','nchar') THEN t.name+'('+CASE WHEN s.max_length<0 then 'MAX' ELSE CONVERT(varchar(10),s.max_length/2) END+')'
            WHEN t.name IN ('numeric') THEN t.name+'('+CONVERT(varchar(10),s.precision)+','+CONVERT(varchar(10),s.scale)+')'
             ELSE t.name
         END AS DataType

        ,CASE
             WHEN s.is_nullable=1 THEN 'NULL'
            ELSE 'NOT NULL'
        END AS Nullable
        ,CASE
             WHEN ic.column_id IS NULL THEN ''
             ELSE ' identity('+ISNULL(CONVERT(varchar(10),ic.seed_value),'')+','+ISNULL(CONVERT(varchar(10),ic.increment_value),'')+')='+ISNULL(CONVERT(varchar(10),ic.last_value),'null')
         END
        +CASE
             WHEN sc.column_id IS NULL THEN ''
             ELSE ' computed('+ISNULL(sc.definition,'')+')'
         END
        +CASE
             WHEN cc.object_id IS NULL THEN ''
             ELSE ' check('+ISNULL(cc.definition,'')+')'
         END
            AS MiscInfo
    FROM sys.columns                           s
        INNER JOIN sys.types                   t ON s.system_type_id=t.user_type_id and t.is_user_defined=0
        INNER JOIN sys.objects                 o ON s.object_id=o.object_id
        INNER JOIN sys.schemas                sh on o.schema_id=sh.schema_id
        LEFT OUTER JOIN sys.identity_columns  ic ON s.object_id=ic.object_id AND s.column_id=ic.column_id
        LEFT OUTER JOIN sys.computed_columns  sc ON s.object_id=sc.object_id AND s.column_id=sc.column_id
        LEFT OUTER JOIN sys.check_constraints cc ON s.object_id=cc.parent_object_id AND s.column_id=cc.parent_column_id
    ORDER BY sh.name+'.'+o.name,s.column_id

编辑SQL Server 2000版本

DECLARE @SQL varchar(8000)
SET @SQL=''
SELECT @SQL=@SQL+'UNION
select 
'''+d.name+'.''+sh.name+''.''+o.name,c.name,c.colid
from '+d.name+'..syscolumns            c
    inner join sysobjects  o on c.id=o.id
    INNER JOIN sysusers  sh on o.uid=sh.uid
'
FROM master.dbo.sysdatabases d
SELECT @SQL=RIGHT(@SQL,LEN(@SQL)-5)+'order by 1,3'
--print @SQL
EXEC (@SQL)

编辑
根据一些评论，下面是一个使用

sp\MSforeachdb

的版本：

sp_MSforeachdb 'select 
    ''?'' AS DatabaseName, o.name AS TableName,c.name AS ColumnName
    from sys.columns            c
        inner join ?.sys.objects  o on c.object_id=o.object_id
    --WHERE ''?'' NOT IN (''master'',''msdb'',''tempdb'',''model'')
    order by o.name,c.column_id'

为什么不使用

Select * From INFORMATION_SCHEMA.COLUMNS

您可以使用

Select * From DBNAME.INFORMATION_SCHEMA.COLUMNS

---

在此查询之前，您必须使用

使用[db\u name]

设置当前数据库名称。

对于像我这样的在数据库服务器上获得排序乐趣的人来说，KM解决方案的细微改进

DECLARE @SQL varchar(max)=''

SELECT @SQL=@SQL+'UNION
select 
'''+d.name +'.''+sh.name+''.''+o.name COLLATE SQL_Latin1_General_CP1_CI_AS,c.name COLLATE SQL_Latin1_General_CP1_CI_AS,c.column_id
from '+d.name +'.sys.columns            c
    inner join sys.objects  o on c.object_id=o.object_id
    INNER JOIN sys.schemas  sh on o.schema_id=sh.schema_id
'
FROM sys.databases d

SELECT @SQL=RIGHT(@SQL,LEN(@SQL)-5)+'order by 1,3'
--print @SQL

EXEC (@SQL)

---

（仍然希望我们能找到一种方法来实现这一点，并将其包装到视图中。）

user@KM说出最佳答案

我用这个：

Declare @Table_Name VarChar(100) ,@Column_Name VarChar(100)
Set @Table_Name = ''
Set @Column_Name = ''

Select 
RowNumber = Row_Number() Over( PARTITION BY T.[Name] Order By T.[Name],C.column_id  ),
SCHEMA_NAME( T.schema_id ) As SchemaName ,  
T.[Name] As Table_Name ,
C.[Name] As Field_Name , 
sysType.name ,
C.max_length , C.is_nullable , C.is_identity , C.scale , C.precision  
From Sys.Tables As T
Left Join Sys.Columns As C On ( T.[Object_Id] = C.[Object_Id] )
Left Join sys.types As sysType On ( C.user_type_id = sysType.user_type_id )
Where ( Type = 'U' )
    And ( C.Name Like '%' + @Column_Name + '%' )  
    And ( T.Name Like '%' + @Table_Name + '%' ) 

---

通常，我会尽我所能避免使用游标，但以下查询将为您提供所需的一切：

--Declare/Set required variables
DECLARE @vchDynamicDatabaseName AS VARCHAR(MAX),
        @vchDynamicQuery As VARCHAR(MAX),
        @DatabasesCursor CURSOR

SET @DatabasesCursor = Cursor FOR

--Select * useful databases on the server
SELECT name 
FROM sys.databases 
WHERE database_id > 4 
ORDER by name

--Open the Cursor based on the previous select
OPEN @DatabasesCursor
FETCH NEXT FROM @DatabasesCursor INTO @vchDynamicDatabaseName
WHILE @@FETCH_STATUS = 0
   BEGIN

   --Insert the select statement into @DynamicQuery 
   --This query will select the Database name, all tables/views and their columns (in a comma delimited field)
   SET @vchDynamicQuery =
   ('SELECT ''' + @vchDynamicDatabaseName + ''' AS ''Database_Name'',
          B.table_name AS ''Table Name'',
         STUFF((SELECT '', '' + A.column_name
               FROM ' + @vchDynamicDatabaseName + '.INFORMATION_SCHEMA.COLUMNS A
               WHERE A.Table_name = B.Table_Name
               FOR XML PATH(''''),TYPE).value(''(./text())[1]'',''NVARCHAR(MAX)'')
               , 1, 2, '''') AS ''Columns''
   FROM ' + @vchDynamicDatabaseName + '.INFORMATION_SCHEMA.COLUMNS B
   WHERE B.TABLE_NAME LIKE ''%%''
         AND B.COLUMN_NAME LIKE ''%%''
   GROUP BY B.Table_Name
   Order BY 1 ASC')

   --Print @vchDynamicQuery
   EXEC(@vchDynamicQuery)

   FETCH NEXT FROM @DatabasesCursor INTO @vchDynamicDatabaseName
END
CLOSE @DatabasesCursor
DEALLOCATE @DatabasesCursor
GO

---

我在主查询中添加了一个where子句（例如：B.TABLE_名称，如“”%%“”，B.COLUMN_名称，如“”%%“”），以便您可以根据需要搜索特定的表和/或列。

致所有人：感谢所有帖子和评论，有些不错，但有些更好

第一个大脚本很好，因为它提供了所需的内容。最快和最详细的建议是从SCHEMA.COLUMNS.信息中进行选择

我需要的是找到几乎相同名称和多个数据库的所有错误列。。Sooo，我制作了这两个版本（见下文）…下面两个脚本中的任何一个都可以工作，并在几秒钟内交付货物

在这个链接的其他帖子中，假设第一个代码示例可以成功地用于每个数据库，这对我来说是不可取的。这是因为信息在特定的数据库中，简单地使用“fedb”不会产生正确的结果，它只是不提供访问权限。所以，这就是为什么我使用游标来收集数据库，而忽略那些离线的数据库，在本例中，这是一个实用程序脚本，它是相同的一个很好的用途

总之，我阅读了每个人的帖子，整合了帖子中的所有更正，并从其他优秀作品中写出了两个非常雄辩的脚本。我在下面列出了这两个脚本文件，并将其放置在OneDrive.com上的我的公用文件夹中，您可以通过此链接访问该文件夹：

              WHERE sys.columns.name = ''id'' '
EXEC SP_MSFOREACHDB @Query

提供包含所有数据库中ID列的表的列表。
我刚刚意识到以下查询将提供数据库中表中的所有列名（SQL SERVER 2017）

或者干脆

SELECT Name FROM SYSCOLUMNS

如果你不在乎重复的名字

另一个选项是从
INFORMATION\u SCHEMA

SELECT DISTINCT column_name  FROM INFORMATION_SCHEMA.COLUMNS
ORDER BY column_name

通常更有趣的是有TableName和ColumnName蚂蚁，下面的查询就是这样做的

SELECT 
   Object_Name(Id) As TableName,
   Name As ColumnName
FROM SysColumns

结果是

  TableName    ColumnName
0    Table1    column11
1    Table1    Column12
2    Table2    Column21
3    Table2    Column22
4    Table3    Column23

我用过：

EXEC sp_MSforeachdb 'Use ? Select * From INFORMATION_SCHEMA.COLUMNS '

它似乎满足了我的需要。
你能为SQL Server 2000移植这个例子吗？在SQL Server 2000中没有
sys
对象。用
syscolumns
替换
syscolumns
会有帮助吗？你也可以尝试用sp_MSforeachdbAs运行原始查询，Chris W说，尽管它们没有文档，sp_msforeachdband sp\u msforeachtable在这里很理想。检查一些细节。@Chipmonkey，我修复了这个错误。我将
内部连接sys.objects
更改为
内部连接？.sys.objects
。如果你的名字中有特殊字符，请随意添加方括号。@Davos，谢谢你的建议，如果你遇到问题，是的，这是一个很好的方法o修复它。我讨厌方括号，如果你需要使用它们，你命名项目时出错了。我已更新了我的答案，它将适用于SQL Server 2000上的所有数据库。这是唯一一个不会爆炸的方括号。o
