Create table #yourcolumndetails(
DBaseName varchar(100),
TableSchema varchar(50),
TableName varchar(100),
ColumnName varchar(100),
DataType varchar(100),
CharMaxLength varchar(100))
EXEC sp_MSForEachDB @command1='USE [?];
INSERT INTO #yourcolumndetails SELECT
Table_Catalog
,Table_Schema
,Table_Name
,Column_Name
,Data_Type
,Character_Maximum_Length
FROM INFORMATION_SCHEMA.COLUMNS
WHERE COLUMN_NAME like ''origin'''
select * from #yourcolumndetails
Drop table #yourcolumndetails

为了改进上面的答案,我还包括了视图,并将模式和表/视图连接在一起,使结果更加明显。
DECLARE @COLUMNNAME AS VARCHAR(100);
SET @COLUMNNAME = '%Absence%';
SELECT CASE
WHEN [T].[NAME] IS NULL
THEN 'View'
WHEN [T].[NAME] = ''
THEN 'View'
ELSE 'Table'
END AS [TYPE], '[' + [S].[NAME] + '].' + '[' + CASE
WHEN [T].[NAME] IS NULL
THEN [V].[NAME]
WHEN [T].[NAME] = ''
THEN [V].[NAME]
ELSE [T].[NAME]
END + ']' AS [TABLE], [C].[NAME] AS [COLUMN]
FROM [SYS].[SCHEMAS] AS [S] LEFT JOIN [SYS].[TABLES] AS [T] ON [S].SCHEMA_ID = [T].SCHEMA_ID
LEFT JOIN [SYS].[VIEWS] AS [V] ON [S].SCHEMA_ID = [V].SCHEMA_ID
INNER JOIN [SYS].[COLUMNS] AS [C] ON [T].OBJECT_ID = [C].OBJECT_ID
OR
[V].OBJECT_ID = [C].OBJECT_ID
INNER JOIN [SYS].[TYPES] AS [TY] ON [C].[SYSTEM_TYPE_ID] = [TY].[SYSTEM_TYPE_ID]
WHERE [C].[NAME] LIKE @COLUMNNAME
GROUP BY '[' + [S].[NAME] + '].' + '[' + CASE
WHEN [T].[NAME] IS NULL
THEN [V].[NAME]
WHEN [T].[NAME] = ''
THEN [V].[NAME]
ELSE [T].[NAME]
END + ']', [T].[NAME], [C].[NAME], [S].[NAME]
ORDER BY '[' + [S].[NAME] + '].' + '[' + CASE
WHEN [T].[NAME] IS NULL
THEN [V].[NAME]
WHEN [T].[NAME] = ''
THEN [V].[NAME]
ELSE [T].[NAME]
END + ']', CASE
WHEN [T].[NAME] IS NULL
THEN 'View'
WHEN [T].[NAME] = ''
THEN 'View'
ELSE 'Table'
END, [T].[NAME], [C].[NAME];
下面是Sybase数据库的工作解决方案
select
t.table_name,
c.column_name
from
systab as t key join systabcol as c
where
c.column_name = 'MyColumnName'
如果你更喜欢第三方工具,有很多选择,比如:
ApexSQL搜索SSMS工具包红门工具。
如果您的数据库包含加密对象(视图、过程、函数),则这些对象非常有用,因为您无法使用系统表轻松搜索这些对象。
您可以尝试以下查询:
USE AdventureWorks
GO
SELECT t.name AS table_name,
SCHEMA_NAME(schema_id) AS schema_name,
c.name AS column_name
FROM sys.tables AS t
INNER JOIN sys.columns c ON t.OBJECT_ID = c.OBJECT_ID
WHERE c.name LIKE '%myName%'
如果只需要表名,可以运行:
select object_name(object_id) from sys.columns
where name like '%received_at%'
如果你也想要Schema Name(在很多情况下你会这样做,因为你会有很多不同的模式,除非你能记住数据库中的每个表及其所属的位置,否则这可能很有用),运行:
select OBJECT_SCHEMA_NAME(object_id),object_name(object_id) from sys.columns
where name like '%received_at%'
最后,如果你想要一个更好的格式(尽管这是代码(在我看来)变得太复杂而不容易编写的地方):
select concat(OBJECT_SCHEMA_NAME(object_id),'.',object_name(object_id)) from sys.columns
where name like '%received_at%'
注意,您还可以根据我的功能创建一个函数:
CREATE PROCEDURE usp_tablecheck
--Scan through all tables to identify all tables with columns that have the provided string
--Stephen B
@name nvarchar(200)
AS
SELECT CONCAT(OBJECT_SCHEMA_NAME(object_id),'.',object_name(object_id)) AS [Table Name], name AS [Column] FROM sys.columns
WHERE name LIKE CONCAT('%',@name,'%')
ORDER BY [Table Name] ASC, [Column] ASC
GO
值得注意的是,凹入功能是在2012年添加的。对于2008r2和更早版本,使用+连接字符串。
自从我发布这个之后,我已经重新格式化了进程。它现在有点高级了,但看起来更乱了(但它在一个proc中,所以你永远不会看到它),而且格式更好。
此版本允许您将其保存在管理数据库中,然后在任何数据库中进行搜索。将@db的分隔符从“master”更改为您希望的默认数据库(注意:除非将字符串连接更改为使用+运算符,否则使用CONCAT()函数只能用于2012+)。
CREATE PROCEDURE [dbo].[usp_tablecheck]
--Scan through all tables to identify all tables in the specified database with columns that have the provided string
--Stephen B
@name nvarchar(200)
,@db nvarchar(200) = 'master'
AS
DECLARE @sql nvarchar(4000) = CONCAT('
SELECT concat(OBJECT_SCHEMA_NAME(col.object_id,DB_ID(''',@db,''')),''.'',object_name(col.object_id,DB_ID(''',@db,'''))) AS [Table Name]
,col.name AS [Column]
FROM ',@db,'.sys.columns col
LEFT JOIN ',@db,'.sys.objects ob
ON ob.object_id = col.object_id
WHERE
col.name LIKE CONCAT(''%'',''',@name,''',''%'')
AND ob.type =''U''
ORDER BY [Table Name] ASC
,[Column] ASC')
EXECUTE (@sql)
GO
