Question

第一种情况将在查询中进行编译，但是当我添加第二种情况时，会出现以下错误＆＃34;＆＃39; program＆＃39;＆＃34;附近的语法错误。如何在更新中使用IN子句的列表。 2008R

       academic_session =  CASE PC.KEY5 
                                WHEN 'AGS' THEN 'AGS' 
                                WHEN 'TRD' THEN 'Traditional'
                           END,
       program = CASE PC.KEY3
            WHEN PC.KEY3 IN ('FF-AGS', 'FF-TRD', 'TR-AGS', 'CH-TRD', 'CO-TRD', 'RE-TRD', 'TR-TRD', 'WDVW') THEN 'Undergraduate'
            WHEN PC.KEY3 = 'CROSS' THEN 'CROSS'
            WHEN PC.KEY3 = 'GR-AGS' THEN 'Graduate'
            WHEN PC.KEY3 IN ('ND-AGS', 'ND-TRD') THEN 'Non Degree Seeking'
        END program,

程序＆＃39;附近的语法不正确。

将每个条件发布在单独的行上并进行编译。

       program = CASE PC.KEY3
            --WHEN PC.KEY3 IN ('FF-AGS', 'FF-TRD', 'TR-AGS', 'CH-TRD', 'CO-TRD', 'RE-TRD', 'TR-TRD', 'WDVW') THEN 'Undergraduate' --"Incorrect syntax near the keyword 'IN'"
            WHEN 'FF-AGS' THEN 'Undergraduate'
            WHEN 'FF-TRD' THEN 'Undergraduate'
            WHEN 'TR-AGS' THEN 'Undergraduate'
            WHEN 'CH-TRD' THEN 'Undergraduate'           
            WHEN 'CO-TRD' THEN 'Undergraduate'               
            WHEN 'RE-TRD' THEN 'Undergraduate'           
            WHEN 'TR-TRD' THEN 'Undergraduate'           
            WHEN 'WDVW' THEN 'Undergraduate'                 
            WHEN 'CROSS' THEN 'CROSS'
            WHEN 'GR-AGS' THEN 'Graduate'
            WHEN 'ND-AGS' THEN 'Non Degree Seeking'
            WHEN 'ND-TRD' THEN 'Non Degree Seeking'
        END,

Answer 1

尝试以下

academic_session =  CASE PC.KEY5 
                                WHEN 'AGS' THEN 'AGS' 
                                WHEN 'TRD' THEN 'Traditional'
                                ELSE NULL
                           END,
 program = CASE WHEN PC.KEY3 IN ('FF-AGS', 'FF-TRD', 'TR-AGS', 'CH-TRD', 'CO-TRD', 'RE-TRD', 'TR-TRD', 'WDVW') THEN 'Undergraduate'
           CASE WHEN PC.KEY3 = 'CROSS' THEN 'CROSS'
           CASE WHEN PC.KEY3 = 'GR-AGS' THEN 'Graduate'
           CASE WHEN PC.KEY3 IN ('ND-AGS', 'ND-TRD') THEN 'Non Degree Seeking'
        ELSE NULL
        END ,
