正则表达式搜索并用Laravel 4的Fluent或Eloquent替换表中的所有行

问题描述

使用Fluent或Eloquent在MySQL数据库中搜索模式并将其替换的最佳方法是什么?

我在Laravel论坛中看到了 能够像这样进行正则表达式选择

// Searching for the word "mypattern"...
Page::where('words', 'regexp', DB::raw('/\bmypattern\b/'))->get();

但是我尝试了这种方法，但似乎没有选择我要的行.无论如何，实际上并不想选择-我实际上想进行搜索并用正则表达式替换.

使用Laravel提供的选项执行此操作的最佳方法是什么?

解决方案

我不认为'regexp'是有效的查询运算符在Laravel 4中.

Taylor实际上已经在Github上的 issue#838下对此问题发表了评论. ，他建议使用whereRaw代替where.

此处是一个有关MySQL Regex Replace的SO问题，它可以帮助您实现这一点. /p>

What's the best way to use Fluent or Eloquent to search for a pattern in a MySQL database and replace it?

I've seen in the Laravel forums that you should be able to do a regex selection like so

// Searching for the word "mypattern"...
Page::where('words', 'regexp', DB::raw('/\bmypattern\b/'))->get();

But I've tried this method and it doesn't seem to select the rows I'm after. In any case, actually don't want to JUST select--I'd like to actually do a search and replace with regex.

What's the best way to do this with the options provided by Laravel?

解决方案

I don't believe that 'regexp' is a valid query operator in Laravel 4.

It seems that Taylor has actually made a comment specific to this issue on Github under issue #838, and he suggests using whereRaw instead of where.

Here is an SO question regarding MySQL Regex Replace, which may help you to implement this.
