How to Create Multiple Where Clause Query Using Laravel Eloquent?

Question

I\'m using the Laravel Eloquent query builder and I have a query where I want a WHERE clause on multiple conditions. It works, but it\'s not elegant.

Answer 1

$projects = DB::table('projects')->where([['title','like','%'.$input.'%'],
    ['status','<>','Pending'],
    ['status','<>','Not Available']])
->orwhere([['owner', 'like', '%'.$input.'%'],
    ['status','<>','Pending'],
    ['status','<>','Not Available']])->get();

Answer 2

In this case you could use something like this:

User::where('this', '=', 1)
    ->whereNotNull('created_at')
    ->whereNotNull('updated_at')
    ->where(function($query){
        return $query
        ->whereNull('alias')
        ->orWhere('alias', '=', 'admin');
    });

It should supply you with a query like:

SELECT * FROM `user` 
WHERE `user`.`this` = 1 
    AND `user`.`created_at` IS NOT NULL 
    AND `user`.`updated_at` IS NOT NULL 
    AND (`alias` IS NULL OR `alias` = 'admin')

Answer 3

The whereColumn method can be passed an array of multiple conditions. These conditions will be joined using the and operator.

Example:

$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();

Answer 4

Without a real example, it is difficult to make a recommendation. However, I've never needed to use that many WHERE clauses in a query and it may indicate a problem with the structure of your data.

It may be helpful for you to learn about data normalization: http://en.wikipedia.org/wiki/Third_normal_form

Answer 5

With Eloquent it is easy to create multiple where check:

First: (Use simple where)

$users = User::where('name', $request['name'])
    ->where('surname', $request['surname'])
    ->where('address', $request['address'])
    ...
    ->get();

Second: (Group your where inside an array)

$users = User::where([
    ['name', $request['name']],
    ['surname', $request['surname']],
    ['address', $request['address']],
    ...
])->get();

You can also use conditional (=, <>, etc.) inside where like this:

$users = User::where('name', '=', $request['name'])
    ->where('surname', '=', $request['surname'])
    ->where('address', '<>', $request['address'])
    ...
    ->get();

Answer 6

You can use array in where clause as shown in below.

$result=DB::table('users')->where(array(
'column1' => value1,
'column2' => value2,
'column3' => value3))
->get();
