如何查找SQL Server中所有数据库中的所有表的列名称
我想查找所有数据库中所有表中的所有列名称。 有没有可以为我做的查询？ 数据库是Microsoft SQL Server 2000。
尝试这个：
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 或者更多的细节：
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

这里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)

基于一些意见，这里是一个使用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'
SELECT * FROM information_schema.columns WHERE column_name = 'My_Column'
在查询之前，您必须USE [db_name]设置当前的数据库名称。
为什么不使用
Select * From INFORMATION_SCHEMA.COLUMNS
你可以使它具体的数据库
Select * From DBNAME.INFORMATION_SCHEMA.COLUMNS
尝试下面的查询
DECLARE @Query VARCHAR(max) SELECT @Query = 'USE ? SELECT ''?'' AS DataBaseName, sys.columns.name AS ColumnName , sys.tables.name AS TableName , schema_name (sys.tables.schema_Id) AS schemaName FROM sys.columns JOIN sys.tables ON sys.columns.object_id = sys.tables.object_id WHERE sys.columns.name = ''id'' ' EXEC SP_MSFOREACHDB @Query
从所有数据库中提供包含ID列的表的列表。
用户@KM说最好的答案。
我使用这个：
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，但是下面的查询会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_NAME LIKE''%%''和B.COLUMN_NAME LIKE''%%'），以便您可以search特定的表和/或列。
更好的方式给你
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%'''
对于像我这样在数据库服务器上整理好乐趣的人，KM的解决scheme稍作改进。
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find一种方法来做到这一点，可以包装成一个视图。）
对大家：感谢所有的post和评论有些是好的，但有些更好。
第一个大脚本是好的，因为它是提供所需的。 最快和最详细的是从INFORMATION_SCHEMA.COLUMNS中select一个build议。
我的需要是find大致相同的名称和几个数据库的所有错误列。所以，我做了我的两个版本（见下文）…下面的脚本中的任何一个工作，并在几秒钟内交付货物。
在这个链接上的其他post中的假设是，第一个代码示例可以成功地用于每个数据库，对我来说是不可取的。 这是因为信息是在特定的数据库中，并且“fedb”的简单使用不会产生正确的结果，所以根本不会给出访问权限。 所以这就是为什么我用CURSOR来收集数据库而忽略那些脱机的，在这种情况下，这是一个实用程序脚本，这是一个很好的用法。
底线，我读了大家的post，整理了post中的所有更正，做出了两个非常雄辩的脚本，从别人的好作品。 我在下面列出，并且还将脚本文件放置在OneDrive.com的公用文件夹中，您可以通过以下链接访问它： http : //1drv.ms/1vr8yNX
