如何在一个 mysql_query 中执行多个 SQL 语句? [英] How do you do multiple SQL statements in one mysql_query?

问题描述

说我想做 UPDATE table SET name = 'bob' 和 UPDATE table SET age = 55 WHERE name = 'jim' 我如何在相同的mysql_query()?

Say I wanted to do UPDATE table SET name = 'bob' and UPDATE table SET age = 55 WHERE name = 'jim' how do I do them in the same mysql_query()?

由于这个问题有相当多的观点，我想指出，从 PHP 5.5 mysql_query 和其他 mysql_* 函数现已弃用，不应使用.

Since this question has a fair amount of views I'd like to point out that as of PHP 5.5 mysql_query and other mysql_* functions are now deprecated and shouldn't be used.

推荐答案

这个我没试过，不过我觉得你可以用 mysqli::multi_query.mysql_query 拒绝多个语句的好处之一是它立即排除了一些更常见的 SQL 注入攻击，例如添加 ';DELETE FROM ... # 到一个语句.因此，您可能需要小心处理多个语句.

I've never tried this, but I think you can use mysqli::multi_query. One of the good things about mysql_query rejecting multiple statements is that it immediately rules out some of the more common SQL injection attacks, such as adding '; DELETE FROM ... # to a statement. You might therefore want to be careful with multiple statements.
