轉換SQL查詢SELECT SUM到laravel 5

Question

我有這樣的SQL查詢

select sum(repayment_borrower.settle_amount+ repayment_borrower.settle_interest + repayment_borrower.settle_penalty) as Total Default 
    FROM repayment_borrower,loans,loan_offer, lender 
    WHERE repayment_borrower.loans_id = loans.id 
    AND loan_offer.loan_id = loans.id 
    AND loans.lnsts <> 999 
    AND loans.lnsts = 810 
    AND loan_offer.lender_id = lender.id 
    and lender.user_id = "3" 

此代碼的工作，當我在SQL phpMyAdmin的申請。但是，當我在laravel轉換這樣

$count_badloans  = DB::select(DB::raw("SELECT sum(repayment_borrower.settle_amount+ repayment_borrower.settle_interest + repayment_borrower.settle_penalty) as Total Default 
                FROM repayment_borrower,loans,loan_offer, lender 
                WHERE repayment_borrower.loans_id = loans.id 
                AND loan_offer.loan_id = loans.id 
                AND loans.lnsts <> 999 
                AND loans.lnsts = 810 
                AND loan_offer.lender_id = lender.id 
                and lender.user_id = $userId ")); 

錯誤發生這樣的

error

我錯了申請查詢到laravel？請幫忙.....

在此先感謝。

Answer 1

嘗試做這樣的，合計設定默認爲Total_Default（無空格）或簡單的總

$count_badloans = DB::select("SELECT sum(repayment_borrower.settle_amount+ repayment_borrower.settle_interest + repayment_borrower.settle_penalty) as Total 
               FROM repayment_borrower,loans,loan_offer, lender 
               WHERE repayment_borrower.loans_id = loans.id 
               AND loan_offer.loan_id = loans.id 
               AND loans.lnsts <> 999 
               AND loans.lnsts = 810 
               AND loan_offer.lender_id = lender.id 
               and lender.user_id = $userId ");

@arbong您可以刪除別名Total Default嗎？

$count_badloans  = DB::select(DB::raw("SELECT 
    SUM(repayment_borrower.settle_amount + repayment_borrower.settle_interest + repayment_borrower.settle_penalty) 
FROM repayment_borrower, 
    loans, 
    loan_offer, 
    lender 
WHERE repayment_borrower.loans_id = loans.id 
AND loan_offer.loan_id = loans.id 
AND loans.lnsts <> 999 
AND loans.lnsts = 810 
AND loan_offer.lender_id = lender.id 
AND lender.user_id = $userId "));
