是否可以查询包含以下列的表名
LIKE '%myName%'

是否可以查询包含以下列的表名
LIKE '%myName%'
?
这应该是有效的:
SELECT name
FROM sysobjects
WHERE id IN ( SELECT id
FROM syscolumns
WHERE name like '%column_name%' )
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;
SELECT COLUMN_NAME, TABLE_NAME
FROM INFORMATION_SCHEMA.COLUMNS
WHERE COLUMN_NAME LIKE '%myName%'
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
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字段名为“%myName”的数据库的确切表名。
SELECT distinct(TABLE_NAME)
FROM INFORMATION_SCHEMA.COLUMNS
WHERE COLUMN_NAME LIKE '%myName%'
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%'
这里将为您提供一些有关架构、表和列的额外信息,您可以选择或不选择在where子句中使用额外条件进行筛选
and c.is_nullable = 0
您可以添加其他条件,我也以这种垂直方式添加了select子句中的列,以便根据您的需要轻松地重新排序、删除、重命名或添加其他列。或者,您可以使用T.Name搜索表格。它非常可定制。
享受
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。
SELECT [TABLE_NAME] ,
[INFORMATION_SCHEMA].COLUMNS.COLUMN_NAME
FROM INFORMATION_SCHEMA.COLUMNS
WHERE INFORMATION_SCHEMA.COLUMNS.COLUMN_NAME LIKE '%NAME%' ;
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,但我想做的是在sql语句中生成一个sql语句,这将允许我搜索我要查找的值(而不仅仅是具有这些字段名称的表(因为通常我需要删除与我要查找列名称的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,以备不时之需。
注意***在运行delete语句之前,请确保消除所有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%'
我刚试过,这个效果很好
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YourDatabaseName更改为数据库,将YourcolumnName更改为您要查找的列名,其余的保持原样。
希望这有所帮助
我不知道为什么很多人建议使用sys.columns加入sys.table。
您可以使用以下代码:
SELECT Object_name(object_id) AS TableName,
*
FROM sys.columns
WHERE NAME LIKE '%MyName%'
or
如果还需要架构名称:
SELECT *
FROM information_schema.columns
WHERE column_name LIKE '%MyName%'
我出于同样的目的使用了这个,它起到了作用:
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];
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 '%Label%'
ORDER BY schema_name, table_name;
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
SQL Server:
SELECT Table_Name, Column_Name
FROM INFORMATION_SCHEMA.COLUMNS
WHERE TABLE_CATALOG = 'YOUR_DATABASE'
AND COLUMN_NAME LIKE '%YOUR_COLUMN%'
神谕:
SELECT owner, table_name, column_name
FROM all_tab_columns
WHERE column_name LIKE '%YOUR_COLUMN_NAME%'
AND OWNER IN ('YOUR_SCHEMA_NAME');
就这么简单!!(SQL,PL/SQL)我一直使用它来查找给定数据库(模式)中列名的所有实例。
像oracle一样,您可以通过以下方式查找表和列:
select table_name, column_name
from user_tab_columns
where column_name
like '%myname%';
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%'
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
要获取完整信息: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%'
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%'
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'
用于显示具有指定列名的所有表的SQL查询:
SELECT SCHEMA_NAME(schema_id) + '.' + t.name AS 'Table Name'
FROM sys.tables t
INNER JOIN sys.columns c ON c.object_id = t.object_id
WHERE c.name like '%ColumnName%'
ORDER BY 'Table Name'
我想要一些不会让我眼睛流血的桌子和视图。
查询
SELECT
t.TABLE_TYPE AS [Type],
c.TABLE_NAME AS [Object],
c.COLUMN_NAME AS [Column]
FROM
INFORMATION_SCHEMA.COLUMNS AS c
LEFT JOIN INFORMATION_SCHEMA.TABLES AS t ON
t.TABLE_CATALOG = c.TABLE_CATALOG AND
t.TABLE_SCHEMA = c.TABLE_SCHEMA AND
t.TABLE_NAME = c.TABLE_NAME
WHERE
c.COLUMN_NAME LIKE '%myName%'
ORDER BY
[Type],
[Object],
[Column]
后果
Type Object Column
----------------------------
BASE TABLE Table1 myName1
BASE TABLE Table2 myName2
VIEW View1 myName1
VIEW View2 myName2
这是你问题的答案
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%';
在MS SQL Server数据库中,使用此查询获取包含输入文本的表和相应的列名:
SELECT t.name AS tableName, c.name AS columnName
FROM sys.tables as t
INNER JOIN sys.columns AS c ON t.object_id=c.object_id
WHERE c.name LIKE '%<your_search_string>%'
在MS SQL中,可以编写以下行来检查特定表的列名:
sp_help your_tablename
或者,您可以先在查询窗口中选择表名(突出显示模式和表名),然后按下下面的组合键:
Alt + F1
此外,还可以找到具有指定模式的列名。
SELECT 'DBName' AS DBName,
column_name,
table_name,
table_schema
FROM dbname.information_schema.columns
WHERE column_name LIKE '%YourColumnName%'
AND table_schema IN ( 'YourSchemaName' )
您还可以在多个数据库中找到同一列。
SELECT 'DBName1' AS DB,
column_name,
table_name,
table_schema
FROM dbname1.information_schema.columns
WHERE column_name LIKE '%YourColumnName%'
UNION
SELECT 'DBName2' AS DB,
column_name,
table_name,
table_schema
FROM dbname2.information_schema.columns
WHERE column_name LIKE '%YourColumnName%'
SELECT table_schema + '.' + table_name,
column_name
FROM [yourdatabase].information_schema.columns
WHERE column_name LIKE '%myName%'
这将为您提供需要查找的列的表名。
这个简单的查询对我有用。
SELECT TABLE_NAME, COLUMN_NAME
FROM INFORMATION_SCHEMA.COLUMNS
WHERE table_schema = 'schemaName'
AND column_name like '%model%';
您可以在SQL Server中使用以下查询。
SELECT column_name AS 'ColumnName',
table_name AS 'TableName'
FROM information_schema.columns
WHERE column_name LIKE '%columnname%'
AND table_schema = 'schema'
ORDER BY tablename,
columnname;
它将返回table_name、schema_name、column_name
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 '%colName%'
ORDER BY schema_name,
table_name;
