我有2-3个不同的列名,我想在整个数据库中查找,并列出所有具有这些列的表。有没有简单的脚本?

获取数据库YourDatabase中所有列为columnna或ColumnB的表:

SELECT DISTINCT TABLE_NAME 
    FROM INFORMATION_SCHEMA.COLUMNS
    WHERE COLUMN_NAME IN ('columnA','ColumnB')
        AND TABLE_SCHEMA='YourDatabase';

对于那些与此相反的搜索,即寻找不包含特定列名的表,这里是查询…

SELECT DISTINCT TABLE_NAME FROM information_schema.columns WHERE 
TABLE_SCHEMA = 'your_db_name' AND TABLE_NAME NOT IN (SELECT DISTINCT 
TABLE_NAME FROM information_schema.columns WHERE column_name = 
'column_name' AND TABLE_SCHEMA = 'your_db_name');

当我们开始缓慢地实现InnoDB特殊的ai_col列的使用,并需要找出200个表中哪些表还没有升级时,这真的很方便。

使用这一行查询。将desired_column_name替换为列名。

SELECT TABLE_NAME FROM information_schema.columns WHERE column_name = 'desired_column_name';

一个简单的方法:

SELECT *
FROM information_schema.columns
WHERE column_name = 'column_name';
select distinct table_name 
from information_schema.columns 
where column_name in ('ColumnA') 
    and table_schema='YourDatabase';
    and table_name in 
    (
        select distinct table_name 
        from information_schema.columns 
        where column_name in ('ColumnB')
              and table_schema='YourDatabase';
    );

这^^将得到表的列na和ColumnB,而不是列na或ColumnB,就像接受的答案

如果你想“只获取所有的表”,那么使用这个查询:

SELECT TABLE_NAME
FROM INFORMATION_SCHEMA.TABLES
WHERE TABLE_NAME like '%'
and TABLE_SCHEMA = 'tresbu_lk'

如果你想“获取所有带列的表”,那么使用这个查询:

SELECT DISTINCT TABLE_NAME, COLUMN_NAME
FROM INFORMATION_SCHEMA.COLUMNS
WHERE column_name LIKE '%'
AND TABLE_SCHEMA='tresbu_lk'
