Question

我是否可以对指定的变量进行案例比较＆＃39; YRSUMGTHAN75＆＃39 ;?当我尝试case statement时，它会咆哮我说＆＃39;＆gt;＆＃39;＆＃39;＆＃39;附近的语法不正确。

这是我的SQL：

SELECT A.DUR, A.TL_QUANTITY,
(SELECT SUM(TL_QUANTITY) FROM PS_TL_RPTD_TIME 
WHERE DUR BETWEEN '01-01-2013' AND '12-31-2013' AND EMPLID = A.EMPLID AND TRC IN   ('JNC', 'SRJ')
HAVING SUM(TL_QUANTITY) > 75) AS YRSUMGTHAN75 

CASE YRSUMGTHAN75 WHEN > 75 THEN 'NewValue'
End

FROM PS_TL_RPTD_TIME A WHERE  A.EMPLID = '10000106052' AND A.DUR > '01-01-2013'

Answer 1

我并不完全明白你要做的是什么，但可能就是这样：

select 
    DUR, 
    TL_QUANTITY, 
    case when YRSUMGTHAN75 > 75 then 'NewValue' else 'OldValue' end
from
    (
    SELECT 
        A.DUR, 
        A.TL_QUANTITY,
        (SELECT SUM(TL_QUANTITY) 
         FROM PS_TL_RPTD_TIME 
         WHERE DUR BETWEEN '01-01-2013' AND '12-31-2013' AND EMPLID = A.EMPLID AND TRC IN   ('JNC', 'SRJ')
         HAVING SUM(TL_QUANTITY) > 75) AS YRSUMGTHAN75 
    FROM 
        PS_TL_RPTD_TIME A 
    WHERE  
        A.EMPLID = '10000106052' AND A.DUR > '01-01-2013'
    ) dt

如果这没有帮助，请使用虚拟表格和数据构建一个小人工示例，以清楚地说明您的问题。

是否可以在sql server中对指定的变量进行case语句比较？
