?


当前回答

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'

       END AS [TYPE], '[' + [S].[NAME] + '].' + '[' + CASE
                                                          WHEN [T].[NAME] IS NULL

                                                    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
