是否可以查询包含以下列的表名

LIKE '%myName%'

?


当前回答

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。

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%';

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%' 

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%'
