我使用Laravel雄辩的查询构建器，我有一个查询，我想在多个条件上有一个where子句。它能起作用，但并不优雅。
例子:
$results = User::where('this', '=', 1)
->where('that', '=', 1)
->where('this_too', '=', 1)
->where('that_too', '=', 1)
->where('this_as_well', '=', 1)
->where('that_as_well', '=', 1)
->where('this_one_too', '=', 1)
->where('that_one_too', '=', 1)
->where('this_one_as_well', '=', 1)
->where('that_one_as_well', '=', 1)
->get();
有没有更好的方法，或者我应该坚持这个方法?
当前回答
使用Eloquent很容易创建多个where检查:
首先:(使用简单的where)
$users = User::where('name', $request['name'])
->where('surname', $request['surname'])
->where('address', $request['address'])
...
->get();
第二个:(在数组中分组where)
$users = User::where([
['name', $request['name']],
['surname', $request['surname']],
['address', $request['address']],
...
])->get();
你也可以在里面使用条件(=，<>，等等)，就像这样:
$users = User::where('name', '=', $request['name'])
->where('surname', '=', $request['surname'])
->where('address', '<>', $request['address'])
...
->get();
其他回答
你可以在Laravel 5.3中使用eloquent
所有的结果
UserModel::where('id_user', $id_user)
->where('estado', 1)
->get();
部分结果
UserModel::where('id_user', $id_user)
->where('estado', 1)
->pluck('id_rol');
在Eloquent中，你可以这样做:
$results = User::where('this', '=', 1)
->orWhere('that', '=', 1)
->orWhere('this_too', '=', 1)
->orWhere('that_too', '=', 1)
->orWhere('this_as_well', '=', 1)
->orWhere('that_as_well', '=', 1)
->orWhere('this_one_too', '=', 1)
->orWhere('that_one_too', '=', 1)
->orWhere('this_one_as_well', '=', 1)
->orWhere('that_one_as_well', '=', 1)
->get();
你可以这样做，这是最短的方法。
$results = User::where(['this'=>1,
'that'=>1,
'this_too'=>1,
'that_too'=>1,
'this_as_well'=>1,
'that_as_well'=>1,
'this_one_too'=>1,
'that_one_too'=>1,
'this_one_as_well'=>1,
'that_one_as_well'=>1])->get();
使用Array的条件:
$users = User::where([
'column1' => value1,
'column2' => value2,
'column3' => value3
])->get();
将产生如下查询:
SELECT * FROM TABLE WHERE column1 = value1 and column2 = value2 and column3 = value3
使用匿名函数的条件:
$users = User::where('column1', '=', value1)
->where(function($query) use ($variable1,$variable2){
$query->where('column2','=',$variable1)
->orWhere('column3','=',$variable2);
})
->where(function($query2) use ($variable1,$variable2){
$query2->where('column4','=',$variable1)
->where('column5','=',$variable2);
})->get();
将产生如下查询:
SELECT * FROM TABLE WHERE column1 = value1 and (column2 = value2 or column3 = value3) and (column4 = value4 and column5 = value5)
whereColumn方法可以传递一个包含多个条件的数组。这些条件将使用and操作符进行连接。
例子:
$users = DB::table('users')
->whereColumn([
['first_name', '=', 'last_name'],
['updated_at', '>', 'created_at']
])->get();
$users = User::whereColumn([
['first_name', '=', 'last_name'],
['updated_at', '>', 'created_at']
])->get();
