我想在所有数据库中找到所有列中的所有列名称。有查询可以帮我吗？该数据库是Microsoft SQL Server 2000。
答案 0 :(得分：88)
试试这个：
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
使用结果列名称，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
或者更多细节：
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

以下是获取所有数据库中所有列的基本示例：
DECLARE @SQL varchar(max)
SET @SQL=''
SELECT @SQL=@SQL+'UNION
select
'''+d.name+'.''+sh.name+''.''+o.name,c.name,c.column_id
from '+d.name+'.sys.columns c
inner join '+d.name+'.sys.objects o on c.object_id=o.object_id
INNER JOIN '+d.name+'.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)
编辑 SQL Server 2000版
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)
修改
根据一些评论，这是一个使用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'
答案 1 :(得分：21)
SELECT *
FROM information_schema.columns
WHERE column_name = 'My_Column'
在此查询之前，您必须使用USE [db_name]设置当前数据库名称。
答案 2 :(得分：20)
为什么不使用
Select * From INFORMATION_SCHEMA.COLUMNS
您可以使用
将其设为特定数据库Select * From DBNAME.INFORMATION_SCHEMA.COLUMNS
答案 3 :(得分：3)
更好的方式
sp_MSForEachDB @command1='USE ?;
SELECT
Table_Catalog
,Table_Schema
,Table_Name
,Column_Name
,Data_Type
,Character_Maximum_Length
FROM INFORMATION_SCHEMA.COLUMNS
WHERE COLUMN_NAME like ''%ColumnNameHere%'''

用户@KM说最好的答案。
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 + '%' )
答案 5 :(得分：1)
通常我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
我在主要查询中添加了一个where子句（例如：B.TABLE_NAME LIKE＆＃39;＆＃39; %%＆＃39;＆＃39; AND B.COLUMN_NAME LIKE＆＃39;＆＃39; %%＆＃39;＆＃39;）以便您可以根据需要搜索特定的表格和/或列。

对所有人：感谢所有的帖子和评论有些是好的，但有些更好。
第一个大脚本是好的，因为它提供了所需的东西。最快和最详细的是从INFORMATION_SCHEMA.COLUMNS ..
中选择的一个建议我的需求是找到大致相同名称和几个数据库的所有错误列。所以，我制作了我的两个版本（见下文）......以下两个脚本中的任何一个工作并在几秒钟内交付货物
此链接上其他帖子的假设是，第一个代码示例可以成功地与for-each-database一起使用，对我来说是不可取的。这是因为信息是在特定的数据库中，而“fedb”的简单使用不会产生正确的结果，它根本就不提供访问权限。 SOOO就是为什么我使用CURSOR来收集数据库并忽略那些离线的数据库，在这种情况下，它是一个实用程序脚本，它是一个很好的用途。
底线，我阅读了所有人的帖子，结合了帖子中的所有更正，并制作了两个非常雄辩的脚本来自其他好作品。我在下面列出了两个，并且还将脚本文件放在OneDrive.com上的公共文件夹中，您可以使用以下链接访问该文件：http://1drv.ms/1vr8yNX

或简单
SELECT DISTINCT NAME FROM SYSCOLUMNS
ORDER BY Name
如果您不关心重复的名称。
另一个选择是SELECT Name FROM SYSCOLUMNS
的SELECT列名
INFORMATION_SCHEMA使用 TableName 和 ColumnName 蚂蚁通常更有趣，下面的查询就是这样做的。
SELECT DISTINCT column_name FROM INFORMATION_SCHEMA.COLUMNS
ORDER BY column_name
结果看起来像
SELECT
