wpQueryBuilder provides a convenient, fluent interface to run database queries. It can be used to perform most database operations in your application.

Instalation

via Composer: composer require alemran/wp-query-builder

 
    require 'vendor/autoload.php';
    
    use wpQueryBuilder\DB;
    
    DB::table('demo')->first()

1. Retrieving A Single Row
   DB::table('users')->first();
2. Retrieving A multiple Row
   DB::table('users')->get();

1. where($column, $value ) :

   DB::table('users')
        ->where('id', 1)
        ->get()

   DB::table('users')
        ->where(function($query){
          $query->where('id', 1);
          $query->orWhere('name', "name");
        })
        ->get()

2. orWhere($column, $value) :

   DB::table('users')
        ->where('id', 1)
        ->orWhere('name', "name")
        ->get()

   DB::table('users')
        ->where('id', 1)
        ->orWhere(function($query){
            $query->where('field', 'value);
            $query->where('field', 'value);
            })
        ->first()

3. whereRaw($query) :

   DB::table('users')
        ->whereRaw('id = 1')
        ->first()

4. orWhereRaw($query) :

   DB::table('users')
        ->whereRaw('id = 1')
        ->orWhereRaw('id = 1')
        ->first()

5. orderBy($columns, $direction) :

   DB::table('users')
        ->orderBy('id', 'desc')

   DB::table('users')
        ->orderBy('id,name', 'desc')

6. groupBy($columns) :

   DB::table('users')
        ->groupBy('id')

   DB::table('users')
        ->groupBy('id,name')

7. limit($number) :

   DB::table('users')
        ->where('id', 1)
        ->limit(number)->get()

8. offset($number) :

   DB::table('users')
        ->where('id', 1)
        ->limit(number)->offset(number)->get()

9. select($fields) :

   DB::table('users')
        ->select('id,name')
           ->get()

10. insert($data) :

    DB::table('users')
         ->insert(['name' => "demo"])

11. update($data,$where) :

    DB::table('users')
         ->where('id', 1)
         ->update(['name' => "demo"])

12. delete($where) :

    DB::table('users')
         ->where('id', 1)
         ->delete()

13. join($table, $first, $operator = null, $second = null) (INNER JOIN):

    DB::table('demo_notes as n')
            ->join('demo_users as u', 'u.id', '=', 'n.user_id')
            ->first()
    

    DB::table('demo_notes as n')
            ->join('demo_users as u', function($query){
              $query->on( 'u.id', '=', 'n.user_id')
              $query->orOn( 'u.id', '=', 'n.user_id')
            })
            ->first()
    

    DB::table('demo_notes as n')
            ->join('demo_users as u', function($query) use($request){
              $query->on( 'u.id', '=', 'n.user_id')
              $query->onWhere( 'u.id', '=', $request->id)
            })
            ->first()
    

    Note: Must use table alias for using join or leftJoin.

14. leftJoin($table, $first, $operator = null, $second = null) (LEFT JOIN): Same as join()
15. transaction():

    DB::startTransaction(function(){
        DB::table('demo_notes')
          ->insert([
             "note" => "Hello",
           ]);
    })

    DB::startTransaction(function(DB $query){
        $query->table('demo_notes')
          ->insert([
             "note" => "Hello",
           ]);
    })
