PL /從選擇值SQL情況下

-2

我需要從有一個case語句一個選擇，如：PL /從選擇值SQL情況下

select buyer id, 
buyer_add 
buyer_city, 
buyer_state, 
, case 
    when Special_Desc like "%ma%" then "Mail" 
    when Special_Desc like "%pa%" then "phone" 
    else " " 
end as Special_Handling 
     from 
      (select string_func(buyer_id) 
       from advance.pledge p) Special_Desc 
from buyer_info 
    where..

換句話說，我需要做的是從一個SELECT語句中產生的Special_desc的情況下，

先謝謝您。

Hi this is an example which illustrates how to use case within a select statement. I hope this query resolves your problem. Please let me know for any issues. Thanks 

SELECT sr_no, 
(SELECT 
CASE 
WHEN UPPER(name)=UPPER('Avrajit') THEN 'My_name1' 
WHEN UPPER(name)=UPPER('Shubhojit') THEN 'My_name2' 
END FROM Avrajit 
) AS condition 
FROM avrajit;

你應該是這樣的：

select buyer id, 
     buyer_add 
     buyer_city, 
     buyer_state, 
     case 
     when regexp_like(s.Special_Desc, 'ma*', 'i') then 'Mail' 
     when regexp_like(s.Special_Desc, 'pa*', 'i') then 'Phone' 
     else ' ' 
     end as Special_Handling 
from (select string_func(buyer_id) 
     from advance.pledge p) s, 
    buyer_info 
where..

cousr你需要兩個表相關。

謝謝你，我從你的查詢中改變了這個部分：from（select string_func（buyer_id）from advance.pledge p）s，to：from（從advance.pledge p選擇string_func（buyer_id））special_Desc，它告訴我缺少右括號和所有parentesis是正確的 – sgg

這是我的實際代碼，但現在它給我'缺少rigth括號，當Sp_Desc喜歡（'馬％'），然後'郵件'時Sp_Desc喜歡（'PA％ '）then'phone'else「」end AS Special_Handling from（string_function（g.buyer_id）from g）AS Sp_Desc – sgg

您不能使用％，這不是正則表達式 – steve

我通過使用case語句裏面的函數解決了這個問題。情況當STRING_FUNCTION（g.gift_donor_id）等（ '％MA％'）然後 'MAIL' 時STRING_FUNCTION（g.gift_donor_id）等（ '％MA％'）然後 '電話' 別的 '' 端as Special_H

謝謝大家的寶貴幫助。
