列出包含给定列名的所有表

Question

如何列出包含给定列名的所有表？我使用的是Mysql版本 4.1.13-nt-日志。我知道小于 5 的版本没有 information_scheme DB。

Answer 1

查找列名称类似于搜索词的所有表和列：

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

Answer 2

试试这个：

mysqldump -u root -p –all-databases –single-transaction > all.sql

然后在文本编辑器中使用 find 以老式方式进行搜索
