在SQL服務器或Oracle中使用case語句

Question

我修改了我對任務2的要求。我想知道是否有人可以幫助我。我嘗試從記錄不在任務＃1和任務＃3中的ITEM列中獲得總和。

非常感謝。

我創建了一個簡單的表格和一些原始數據。我試圖完成以下任務：

1. a.Sum記錄包含'FIRA'作爲FIRA。
   b。記錄中包含'FMUA'作爲FMUA。
   c.Sum記錄包含SOTA作爲SOTA。
   d.Sum記錄包含「PERA」作爲PERA。
   e.Sum記錄包含「SGDA」作爲SGDA。 f。記錄包含'TGDA'作爲TGDA。
   h.Sum記錄包含'CRMA'作爲CRMA。
   

2. 總和並非來自任務＃1和任務＃3 MULTIPLE_CLASSIFICATION記錄。

3. 將上述＃1和＃2以外的剩餘記錄求和爲NONE_CLASSIFICATION。

我才得以完成任務＃1和＃3，但無法完成的任務＃2 下面是我的查詢在SQL Server和Oracle測試。

CREATE TABLE TEMP 
(
    CLASSIFICATION VARCHAR (100), 
    ITEM   INTEGER 
) 

insert into temp values ('CRMA', 66); 
insert into temp values ('FIRA', 1288);

Answer 1

你的任務2包括「FIRA」，其中有1288年由於1288比你期待的總和以上的值，你和查詢應修改爲僅包含值的類型您正在尋找。請參閱您的插入：

insert into temp values ('FIRA', 1288); 

和您的查詢：

--for task #2 
SUM (CASE WHEN (CLASSIFICATION LIKE '%FIRA%' 
OR CLASSIFICATION LIKE '%FMUA%' 
OR CLASSIFICATION LIKE '%SOTA%' 
OR CLASSIFICATION LIKE '%PERA%' 
OR CLASSIFICATION LIKE '%SGDA%' 
OR CLASSIFICATION LIKE '%TGDA%' 
OR CLASSIFICATION LIKE '%CRMA%') THEN ITEM END) AS MULIPLE_CLASSIFICATIONS,
