MySql的通過或失敗Case語句

Question

使用Toad for MySQL，我試圖創建一個查詢，告訴我返回的記錄是否在任何類別中通過或失敗，以便我可以告訴用戶更正它們。

我當前查詢的結果是這樣的：

ID uat_resource風險培訓load_performance pay_associated 1839年
1846年約翰洪水無無無無 1849年馬特·伯爾N/A馬特·伯爾N/AN/A

我想設置它，這樣當任何事情都是空時，它被認爲是失敗，如果風險是不適用或沒有，那麼它也會失敗，因爲總是存在風險。

SELECT cr.ID, 
    cr.risks, 
    cr.training, 
    cr.load_performance, 
    cr.pay_associated 
FROM requests.requests cr 
WHERE cr.id IN (SELECT di.change_request_id 
        FROM dcs_item di 
        WHERE di.current_level = 3) 
    AND cr.production_dt IN ('2012/01/10','2011/01/11') 
ORDER BY ID; 

我試圖做這樣的事情....

SELECT cr.ID, 
    (case when lower(cr.uat_resource) in ('','n/a','none') then 
    'FAIL' else 'PASS') as Test, 
    cr.risks, 
    cr.training, 
    cr.load_performance, 
    cr.pay_associated 
FROM requests.requests cr 
WHERE cr.id IN (SELECT di.change_request_id 
        FROM dcs_item di 
        WHERE di.current_level = 3) 
    AND cr.production_dt IN ('2012/01/10','2011/01/11') 
ORDER BY ID;

你需要一個 「結束」 您的case語句：

SELECT cr.ID, 
    (case when lower(cr.uat_resource) in ('','n/a','none') then 
    'FAIL' else 'PASS' END) as Test, 
    cr.risks, 
    cr.training, 
    cr.load_performance, 
    cr.pay_associated 
FROM requests.requests cr 
WHERE cr.id IN (SELECT di.change_request_id 
        FROM dcs_item di 
        WHERE di.current_level = 3) 
    AND cr.production_dt IN ('2012/01/10','2011/01/11') 
ORDER BY ID;
