请帮助我....基本上，查询不会在语句分组时因为它们具有sum函数....因此，显示要在同一列中合并的多个结果...
答案 0 :(得分：2)
您应该将sum（）函数应用于整个case表达式，如果在派生表中应用datediff和substr函数，则可以避免大量重复。
因此，稍微调整一下您的原始查询后，我们会得到您应该执行此操作的查询：
String str = new String (request.getParameter("string").getBytes ("iso-8859-1"), "UTF-8");
答案 1 :(得分：0)
你想把你的条件存入你的总和。改变这个：
case when datediff(day, to_char(invdtl.fifdte, 'MM/DD/YYYY'), sysdate) < 90
then sum(invdtl.untqty)
else ''
end as "Less than 90"
为：
sum(
case when datediff(day, to_char(invdtl.fifdte, 'MM/DD/YYYY'), sysdate) < 90
then invdtl.untqty
else 0
end)
as "Less than 90"
答案 2 :(得分：0)
您需要SUM超过CASE（并清理您的“翻译”案例：
SELECT SUBSTR(prtmst.typcod, 1, 3) Article_Type,
CASE WHEN SUBSTR(prtmst.typcod, 1, 3) LIKE 'A%' THEN 'Accessories'
