使用SQL语法大小写返回未知错误消息；然后是“1”；

大家好，下面有人能帮我吗？我尝试过将DEC改为INT，但没有效果，我的系统运行的是DERBY语法，它接受了

CASE

，所以不确定下面的内容为什么不起作用

收到的错误消息是：

请显示出现问题的查询。这不是该查询。您使用的是哪个DBMS？

“vol.sales.ratio”

看起来像一个非常奇怪的表名。这是我在我们使用的报表编写软件中创建的一个虚拟表（我知道表名已被拍手）。表从我们的U2（宇宙）中提取数据数据源，并按定义的时间表缓存结果（允许报告编写和可视化仪表板的速度，因为它们在查看时不需要实时）希望这是有意义的？我建议对每个表执行一个简单的

SELECT

，因为表是虚拟的，所以在创建表时可能会触发错误。我认为

AS DEC

应该在所有这些行的括号外

然后强制转换（SUM（G.OSQTY）AS DEC）

。事实上，它甚至不应该存在，因为当它别名为“salesratiosum”时，它无论如何都不会被使用。编辑：整个case语句可能需要一些工作。你不需要像DEC那样的
