如何在雄辩中结合WHERE子句 [英] How to combine WHERE clauses in Eloquent

问题描述

  SELECT * FROM table WHERE status = 1 AND（type = 2 OR type = 3 OR type = 4）
  

我一直找不到一个简单的方法在雄辩中这样做。如果我使用

  Table :: where（'status'，1） - > orWhere（'type'，2） > orWhere（'type'，3）... 
  

这样转换为：

  SELECT * FROM table WHERE status = 1 OR type = 2 OR type = 3 OR type = 4 
  

哪些不是我需要的。创建'status = 1'的查询范围也可以得到相同的结果。如何在Eloquent中运行此查询？

解决方案

要组合这样的子句，您需要将闭包传递给 where（）方法，并在封闭中添加分组条件。因此，您的代码将如下所示：

  Table :: where（'status'，1） - > where （$ q）{
 return $ q-> where（'type'，2） - > orWhere（'type'，3） - > orWhere（'type'，4）; 
 }）; 
  

这将生成SQL：

  SELECT * FROM tables WHERE status = 1 AND（type = 2 OR type = 3 OR type = 4）
  

I would like to have this kind of query in Eloquent:

SELECT * FROM table WHERE status = 1 AND (type = 2 OR type = 3 OR type = 4)

I've been unable to find an easy way of doing this in Eloquent. If I use

Table::where('status', 1)->orWhere('type', 2)->orWhere('type', 3)...

This this translates to:

SELECT * FROM table WHERE status = 1 OR type = 2 OR type = 3 OR type = 4

Which is not what I need. Creating a query scope for 'status = 1' also gets me the same results. How can I run this query in Eloquent?

解决方案

To group where clauses like that, you need to pass a closure to the where() method, and add your grouped conditions inside the closure. So, your code would look something like:

Table::where('status', 1)->where(function ($q) {
    return $q->where('type', 2)->orWhere('type', 3)->orWhere('type', 4);
});

This will generate the SQL:

SELECT * FROM tables WHERE status = 1 AND (type = 2 OR type = 3 OR type = 4)
