如何查找MySQL中具有特定列名的所有表？

Question

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

Answer 1

要获取包含列columnA或ColumnB数据库的所有表YourDatabase:

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

Answer 2

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

Answer 3

更简单地在一行SQL中完成:

SELECT * FROM information_schema.columns WHERE column_name = 'column_name';

Answer 4

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

Answer 5

在没有的information_schema版本(旧版本或某些ndb)中,您可以转储表结构并手动搜索列.

mysqldump -h$host -u$user -p$pass --compact --no-data --all-databases > some_file.sql

现在some_file.sql使用首选文本编辑器搜索列名,或使用一些漂亮的awk脚本.

还有一个简单的sed脚本来查找列,只需将COLUMN_NAME替换为您的:

sed -n '/^USE/{h};/^CREATE/{H;x;s/\nCREATE.*\n/\n/;x};/COLUMN_NAME/{x;p};' <some_file.sql
USE `DATABASE_NAME`;
CREATE TABLE `TABLE_NAME` (
  `COLUMN_NAME` varchar(10) NOT NULL,

您可以直接在sed中管道转储,但这很简单.

Answer 6

对于那些搜索相反的人,即查找不包含某个列名的表,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');

当我们开始慢慢实现InnoDB特殊ai_col列的使用并且需要弄清楚我们的200个表中哪些尚未升级时,这非常方便.

Answer 7

使用这一行查询。将所需的列名替换为您的列名。

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

Answer 8

如果您想" 仅获取所有表 ",请使用此查询:

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

如果您想要" 获取包含列的所有表 ",请使用以下查询:

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

Answer 9

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';
    );

^^ 将获得带有 ColumnA和ColumnB 而不是 ColumnA或ColumnB的表格，就像接受的答案

Answer 10

SELECT DISTINCT TABLE_NAME FROM INFORMATION_SCHEMA.COLUMNS WHERE COLUMN_NAME LIKE '%city_id%' AND TABLE_SCHEMA='database'
