Answer 1

您不能建立這樣的條件。嘗試建立他們的select語句中是這樣的：

select case 
     when exists 
      (select 1 
       from IPA_PRCADJ_HDR 
       where TRM_CODE = 41 
      ) 
     then '111111' 
     else '0000000' 
     end 
from dual 

Answer 2

你可以試試這個：

IF NOT EXISTS (SELECT 1 FROM IPA_PRCADJ_HDR) 
SELECT '111111' FROM DUAL; 
ELSE 
SELECT '0000000' FROM DUAL; 

Answer 3

試試這個

IF((SELECT COUNT(*) FROM IPA_PRCADJ_HDR WHERE TRM_CODE = 41) == 0) 
THEN 
    select '111111' from dual; 
ELSE 
SELECT '0000000' FROM DUAL; 
END IF; 

在if條件，你必須使用 「==」 INSTEAD OF「=」。
