Laravel雄辯 - 如何創建子查詢的查詢，如果保護 - 諮詢熱點

Question

這裏是我的查詢

SELECT 
    IF((SELECT COUNT(*) FROM tablename t WHERE t.field1 = tablename.field1 AND t.field2 IN (50,55,58,60)) = 0,1,0) AS b, 
    field3, 
    field4, 
FROM tablename 
WHERE ProductId = ? 

如何將其轉換爲laravel口才？

Answer 1

如果你已經顯示你已經嘗試過，那會更好。

那說，這應該工作：

$result = App\TablenameModel::where('ProductId', 'your_value_here') 
    ->select(
     \DB::raw('IF((SELECT COUNT(*) FROM tablename t WHERE t.field1 = tablename.field1 AND t.field2 IN (50,55,58,60)) = 0,1,0) AS b'), 
     'field3', 
     'field4' 
    ) 
    ->get();
