Laravel Eloquent "WHERE NOT IN" Query Examples

The wherenotin() database query method takes two parameters. In the first argument, you pass the column name, and the second value you supply is the array id.

Here is the whereNotIn query syntax that you can use in Laravel.

whereIn('column name', 'array')

• Column_name:- Your database table column name.
• Array: – The column’s value is not contained in the given array. Let’s take look at some examples of whereNotIn() eloquent method in laravel.

Example 1: whereNotIn Query Using Simple SQL Query:

SELECT *  FROM users  WHERE id NOT IN (1, 5, 9)

In this SQL query, the data will not be gotten from the DB table. Whose ids will be 1, 5, 9.

Example 2: Eloquent WhereNotIn Query Using Query Builder

public function users()
{
    return DB::table('users')->whereNotIn('id', [1, 5, 9])->get();
}

Example 3: Eloquent WhereNotIn Query Using Laravel Model

public function users()
{
    return User::whereNotIn('id', [1, 5, 9])->get();
}

So far you have seen in the given example. Have used ids for scaping and getting data into DB table. But now for example 4, we will fetch the data by using the DB table column name.

Example 4: Eloquent WhereNotIn Query Using Laravel Model With Different Column Name

public function users()
{
    return User::whereNotIn('email', ["[e-mail]", "[e-mail]"])->get();
}
