Question

查询表达式中出现语法错误（缺少运算符），我怎么了？

SELECT
    ExportUF_NEW.Position, 
    ExportUF_NEW.[User Defined Field 03]
    (CASE
        WHEN ExportUF_NEW.[User Defined Field 03] = OP THEN "Production"
        WHEN ExportUF_NEW.[User Defined Field 03] = STM THEN "Thermal"
        ELSE NULL
    END) AS OperationGroup
FROM ExportUF_NEW
    WHERE (((ExportUF_NEW.[User Defined Field 03]) Is Not Null))

基于ExportUF_NEW [用户定义的字段03]，将结果预期到新列“ OperationGroup”中。

MS Access不支持CASE WHEN，请改用switch。相似链接：What is the equivalent of Select Case in Access SQL?
