Question

誰かが

に、 My Table

SELECT supplier, 
MAX(IF(item_name = 'Lemon', price, NULL)) AS Lemon, 
MAX(IF(item_name = 'Apple', price, NULL)) AS Apple, 
MAX(IF(item_name = 'Durian', price, NULL)) AS Durian,

where status = 'open' 
GROUP BY supplier 

方法Laravel QueryBuilderにより、このクエリを使用するために、この私のデータベースSQLクエリを手伝ってくれるか？ありがとうございました...

Answer 1

$results = DB::table('offer')->select(DB::raw("supplier, 
    MAX(IF(item_name = 'Lemon', price, NULL)) AS Lemon, 
    MAX(IF(item_name = 'Apple', price, NULL)) AS Apple, 
    MAX(IF(item_name = 'Durian', price, NULL)) AS Durian, 
    MAX(IF(item_name = 'Mango', price, NULL)) AS Mango")) 
->where('status', 'open') 
->groupBy('supplier') 
->get(); 

本当に、クエリビルダは複雑なクエリ用に作られていません。彼らはその複雑取得する場合、あなたはそれが簡単だけで生のステートメントを使用して見つけるかもしれない：

$results = DB::select("SELECT supplier, 
    MAX(IF(item_name = 'Lemon', price, NULL)) AS Lemon, 
    MAX(IF(item_name = 'Apple', price, NULL)) AS Apple, 
    MAX(IF(item_name = 'Durian', price, NULL)) AS Durian, 
    MAX(IF(item_name = 'Mango', price, NULL)) AS Mango 
FROM offer 
where status = 'open' 
GROUP BY supplier");
