php - 大型 MySQL 查询和插入

Question

大家好，我是这里的新手，也是 php 的新手，我只接触了大约 2 个月，边走边学。我现在需要做的是从数据库中大约 16 个不同的表中获取数据并复制这些表。该表适用于申请人，并且具有共同的应用程序 ID 或共同的家庭 ID，这些 ID 只是生成的哈希值。我现在正在做的是单独查询每个表，然后使用数据进行插入，只更改应用程序 ID 和/或系列 ID。有些 table 很大，我想找出一种更简单、更快速的方法来做到这一点，这是为我的一张 table 写的示例文章 iv。

Answer 1

你不需要循环所有的行。
使用这个:

Insert into new_table select * from old_table where {your criteria here}
