查找包含具有指定名称的列的所有表 - MS SQL Server_mssql查找库中所有列名-优快云博客

这篇博客讨论了如何在MS SQL Server中查询包含特定列名的表。多个用户分享了不同的T-SQL查询和技巧，包括考虑架构和视图，以及如何根据需要定制查询。此外，还提到了一些第三方工具，如ApexSQL Search和SSMS Toolkit，以辅助搜索过程。

是否可以查询包含列的表名

LIKE '%myName%'

？

#1楼

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 '%EmployeeID%'
ORDER BY schema_name, table_name;

以下查询将为您提供具有字段名称（如'％myName'）的数据库的确切表名。

SELECT distinct(TABLE_NAME)
  FROM INFORMATION_SCHEMA.COLUMNS    
 WHERE COLUMN_NAME LIKE '%myName%'

#3楼

select  
        s.[name]            'Schema',
        t.[name]            'Table',
        c.[name]            'Column',
        d.[name]            'Data Type',
        c.[max_length]      'Length',
        d.[max_length]      'Max Length',
        d.[precision]       'Precision',
        c.[is_identity]     'Is Id',
        c.[is_nullable]     'Is Nullable',
        c.[is_computed]     'Is Computed',
        d.[is_user_defined] 'Is UserDefined',
        t.[modify_date]     'Date Modified',
        t.[create_date]     'Date created'
from        sys.schemas s
inner join  sys.tables  t
on s.schema_id = t.schema_id
inner join  sys.columns c
on t.object_id = c.object_id
inner join  sys.types   d
on c.user_type_id = d.user_type_id
where c.name like '%ColumnName%'

这里将为您提供有关架构，表和列的一些额外信息，您可能会或可能不会选择在where子句中使用额外条件进行筛选。例如，如果您只想查看必须添加值的字段

and c.is_nullable = 0

您可以添加其他条件，我还以这种垂直方式添加了select子句中的列，因此可以根据您的需要轻松地重新排序，删除，重命名或添加其他条件。或者，您可以使用T.Name搜索表。它非常可定制。

请享用。

如果您更多地使用第三方工具，那里有很多选项，例如：

如果您的数据库包含加密对象（视图，过程，函数），则这些非常方便，因为您无法使用系统表轻松搜索这些对象。

#5楼

SELECT  [TABLE_NAME] ,
        [INFORMATION_SCHEMA].COLUMNS.COLUMN_NAME
FROM    INFORMATION_SCHEMA.COLUMNS
WHERE   INFORMATION_SCHEMA.COLUMNS.COLUMN_NAME LIKE '%NAME%' ;

#6楼

DECLARE @columnName as varchar(100)
SET @columnName = 'ColumnName'

SELECT t.name AS Table, c.name AS Column,
ty.name AS Type, c.max_length AS Length
FROM sys.tables AS t
INNER JOIN sys.columns c ON t.OBJECT_ID = c.OBJECT_ID
INNER JOIN sys.types ty ON c.system_type_id = ty.system_type_id
WHERE c.name LIKE @columnName
ORDER BY t.name, c.name

希望这不是一个重复的答案，但我喜欢做的是在sql语句中生成一个sql语句，这将允许我搜索我正在寻找的值（而不仅仅是具有这些字段名称的表（因为它通常是然后我必须删除与我正在寻找的列名的id相关的任何信息）：

  SELECT  'Select * from ' + t.name + ' where ' + c.name + ' = 148' AS SQLToRun
  FROM sys.columns c, c.name as ColName, t.name as TableName
  JOIN sys.tables t 
     ON c.object_id = t.object_id
  WHERE c.name LIKE '%ProjectID%'

然后我可以复制并粘贴运行我的第一列“SQLToRun”...然后我将'Select * from'替换为'Delete from'，它允许我删除对该给定ID的任何引用！将这些结果写入文件，这样你就可以了有它们以防万一。

注意****确保在运行删除语句之前消除任何bakup表...

  SELECT  'Delete from ' + t.name + ' where ' + c.name + ' = 148' AS SQLToRun
  FROM sys.columns c, c.name as ColName, t.name as TableName
  JOIN sys.tables t 
     ON c.object_id = t.object_id
  WHERE c.name LIKE '%ProjectID%'

#8楼

我刚尝试过，这完美无缺

USE YourDatabseName
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 '%YourColumnName%'
ORDER BY schema_name, table_name;

只将YourDatbaseName更改为您的数据库，将YourcolumnName更改为您要查找的列名称，保持原样。

希望这有所帮助

我不知道为什么这么多人建议sys.table with sys.columns加入sys.table with sys.columns你可以简单地使用下面的代码：

Select object_name(object_id) as TableName,* from SYS.columns where name LIKE '%MyName%'

要么

如果您还需要模式名称：

Select * from  INFORMATION_SCHEMA.COLUMNS
where COLUMN_NAME LIKE '%MyName%'

#10楼

我用它来达到同样的目的，它起作用了：

  select * from INFORMATION_SCHEMA.COLUMNS
  where TABLE_CATALOG= 'theDatabase'
  and COLUMN_NAME like 'theCol%'

为了改进上面的答案，我还包括了视图，并将Schema和Table / View连接在一起，使结果更加明显。

SET @COLUMNNAME = '%Absence%';

    c.name AS column_name

如果您只想要表名，则可以运行：

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，你将拥有很多不同的模式，除非你能记住数据库中的每个表以及它所属的位置，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（虽然这是代码（在我看来）变得太复杂，易于编写）：

select concat(OBJECT_SCHEMA_NAME(object_id),'.',object_name(object_id)) from sys.columns
where name like '%received_at%'

请注意，您还可以根据我的内容创建一个函数：

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，2012年添加了concat功能。对于2008r2和更早版本，使用+来连接字符串。

自从我发布这个以来，我已经重新格式化了proc。它现在有点高级，但看起来更麻烦（但它在一个proc中，所以你永远不会看到它）并且它的格式更好。

此版本允许您将其置于管理数据库中，然后搜索任何数据库。将@db从'master'更改为您希望默认数据库的@db （注意：使用CONCAT（）函数仅适用于2012+，除非您更改字符串连接以使用+运算符）。

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

SQL Server：

SELECT Table_Name, Column_Name 
FROM INFORMATION_SCHEMA.COLUMNS
WHERE TABLE_CATALOG = 'YOUR_DATABASE'
AND COLUMN_NAME LIKE '%YOUR_COLUMN%'

甲骨文：

SELECT owner, table_name, column_name 
FROM all_tab_columns 
WHERE column_name LIKE '%YOUR_COLUMN_NAME%'
AND OWNER IN ('YOUR_SCHEMA_NAME');

就那么简单！！（SQL，PL / SQL）
我一直用它来查找给定数据库（模式）中列名的所有实例。

#15楼

像oracle一样，你可以找到表格和列：

select table_name, column_name
from user_tab_columns 
where column_name 
like '%myname%';

#16楼

您可以通过column_name过滤器从INFORMATION_SCHEMA.COLUMNS中找到它

Select DISTINCT TABLE_NAME as TableName,COLUMN_NAME as ColumnName
     From INFORMATION_SCHEMA.COLUMNS Where column_name like '%myname%'

#17楼

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

#18楼

获取完整信息：列名，表名以及表的架构。

SELECT COLUMN_NAME, TABLE_NAME, TABLE_SCHEMA
FROM INFORMATION_SCHEMA.COLUMNS 
WHERE COLUMN_NAME LIKE '%col_Name%'

#19楼

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%'

#20楼

这应该工作：

SELECT name 
FROM sysobjects 
WHERE id IN ( SELECT id 
              FROM syscolumns 
              WHERE name like '%column_name%' )

#21楼

搜索表：

SELECT      c.name  AS 'ColumnName'
            ,t.name AS 'TableName'
FROM        sys.columns c
JOIN        sys.tables  t   ON c.object_id = t.object_id
WHERE       c.name LIKE '%MyName%'
ORDER BY    TableName
            ,ColumnName;

搜索表格和视图：

SELECT      COLUMN_NAME AS 'ColumnName'
            ,TABLE_NAME AS  'TableName'
FROM        INFORMATION_SCHEMA.COLUMNS
WHERE       COLUMN_NAME LIKE '%MyName%'
ORDER BY    TableName
            ,ColumnName;

#22楼

SELECT COLUMN_NAME, TABLE_NAME
  FROM INFORMATION_SCHEMA.COLUMNS    
 WHERE COLUMN_NAME LIKE '%myName%'

#23楼

这是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'

#24楼

我们还可以使用以下语法： -

select * from INFORMATION_SCHEMA.COLUMNS 
where COLUMN_NAME like '%clientid%' 
order by TABLE_NAME
