Laravel雄辩的查询JSON列与在哪里? [英] Laravel Eloquent query JSON column with Where In?
问题描述
我在查询json列时遇到问题.
I am having trouble querying a json column.
以前我的代码是
$query->whereIn('user', $users);
现在,我已将数据库类型更改为JSON列,并正在尝试修改新版本的代码.
Now i have changed the db type to JSON column and am trying to modify the code for the new version.
在RAW MYSQL中有效
In RAW MYSQL this works
JSON_CONTAINS(user, '"tom","Bill"')
但是当我用雄辩的/php来表示它时,它总是会失败或返回提示.在这里,我传入的是用户数组,以前使用的是在原始SQL中工作的WhereIn
But when i put it in eloquent / php it keeps failing or returning noting. Here i am passing in an array of Users, previous using an WhereIn which works in raw SQL
$leads->whereRaw("JSON_CONTAINS(user, '"$users"')")
任何想法如何使其在Laravel中工作,这样我就可以传递一个字符串数组,并根据包含一个字符串数组的json列查询它们.
Any idea how to make it work in Laravel so i can pass in an array of strings, query them against the json column which contains an array of strings too.
我的Json列有这样的数据
My Json colum has data like so
["Paul", "Tom", "Bob"]
推荐答案
MySQL需要JSON字符串:
MySQL expects a JSON string:
$leads->whereRaw('JSON_CONTAINS(user, ?)', [json_encode($users)])
在Laravel 5.6.24中,您可以使用whereJsonContains()
:
In Laravel 5.6.24 you can use whereJsonContains()
:
$leads->whereJsonContains('user', $users)
