可能帶有'不喜歡'的案例陳述？

Question

我期待的情況下，所有bacheloreatte度非BA或BS的單獨（例如BSAST）。我嘗試了一個嵌套的case語句，但是因爲我對t-sql比較陌生，所以我不確定它是否是我的語法或者它是不可能的。請注意，這是在一個選擇語句。

SELECT 
t2.ID, 
t2.ACAD_PROGRAM, 
'092013' AS T01, 
'274842' AS T02, 
REPLACE(p.SSN,'-','') AS T03, 
'5' AS T04, 
ap.ACPG_CIP AS T05, 
CASE(t2.ACAD_PROGRAM) 
    WHEN 'BA%' THEN '1' 
    WHEN 'BS' THEN '2' 
    ELSE (CASE 
      WHEN t4.STP_DEGREE LIKE 'BA%' 
      THEN '1' END) 
END AS T06 

Answer 1

CASE has two formats，能夠與LIKE operator，你第一種情況下使用應該是Searched Case：

SELECT t2.ID, t2.ACAD_PROGRAM, '092013' AS T01, '274842' AS T02, 
     REPLACE(p.SSN,'-','') AS T03, '5' AS T04, ap.ACPG_CIP AS T05, 
     CASE WHEN t2.ACAD_PROGRAM LIKE 'BA%' THEN '1' 
      WHEN t2.ACAD_PROGRAM = 'BS' THEN '2' 
     ELSE 
      CASE WHEN t4.STP_DEGREE LIKE 'BA%' THEN '1' END 
     END AS T06
