我在尝试将聚合函数应用于列时遇到此错误，我想要总计它，但即使计数也不起作用。我正在尝试获取没有库存的位置数量。
An error occurred while performing operation 'sqlOpenResult' status='-28'.
这是我用于数据的公式
CASE
WHEN ( [Actual Cases] = '' )
THEN (1)
ELSE (0)
END
任何帮助都会非常感激，我已经搜索过这个并且每个人都说不一致的数据类型，但我显然已经过了1和0，所以我很难过。
以下是有关错误的详细信息：

这可能是数据类型不匹配 - 您的评论也支持此假设。 :)但这是许多Cognos泛型错误之一。有时在Cognos错误报告中会列出一个更好的错误，所以尝试发布整个事情，但是Cognos通常不会给你太多的信息。
如果您具有对数据库或类似（dev）版本的SQL访问权限，则可以通过“属性”菜单为Report Studio中的查询主题生成SQL，然后将Native SQL剪切并粘贴到SQL程序中得到一个更好的错误（或分析/解释以寻找减速）。
如果您没有SQL访问权限，可以尝试在Report Studio中创建基于SQL的查询主题，并以表格模式运行它以查看它是否会产生更有用的错误。
