mysql - AND を使用する場合

Question

Case When条件付きで使用したいのですがAND、合計が正しく計算されていません。

例えば：

SELECT DATE(`SubmitDate`), 
     SUM(CASE status WHEN 'New' AND `Type` = 'consumer' THEN 1 ELSE 0 END) as new_consumer,
     SUM(CASE status WHEN 'New' AND `Type` = 'business' THEN 1 ELSE 0 END) as new_business
FROM report
WHERE `source` = 'net'
group by DATE(`SubmitDate`) Order by `SubmitDate` DESC

Answer 1

CASE WHEN [Condition] THEN...単純なケース式ではなく、使用する必要があります。

SELECT DATE(`SubmitDate`), 
     SUM(CASE WHEN status = 'New' AND `Type` = 'consumer' THEN 1 ELSE 0 END) as new_consumer,
     SUM(CASE WHEN status = 'New' AND `Type` = 'business' THEN 1 ELSE 0 END) as new_business
FROM report
WHERE `source` = 'net'
group by DATE(`SubmitDate`) Order by `SubmitDate` DESC

Answer 2

あなたは書くべきです

CASE  WHEN status='New' AND `Type` = 'consumer' THEN 1 ELSE 0 END

CASE WHENの構文を確認してください
