Cognos Aggregation：执行操作'sqlOpenResult'status =' - 28'时发生错误

Question

尝试将聚合函数应用于列时出现此错误，我想总计它，但即使计数也不起作用。我试图获取没有库存的位置数量。

An error occurred while performing operation 'sqlOpenResult' status='-28'. 

下面是我使用

CASE 
WHEN ([Actual Cases] = '') 
THEN (1) 
ELSE (0) 
END 

任何帮助将不胜感激，我搜索了这一点，每个人的数据公式表示不一致的数据类型，但我清楚地传递1的和0的这样即时难倒。

下面是关于此错误的详细信息：

这可能是一个数据类型不匹配 - 这种假设也由您的意见支持。 :)但这是许多Cognos通用错误之一。有时候Cognos错误报告中列出了一个更好的错误，所以尽量将所有内容都发布出去，但Cognos经常不会让你沉迷于此。

如果您具有对数据库或类似（开发）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程序中以获得更好的错误（或分析/解释寻找减速）。

如果您没有SQL访问权限，则可以尝试在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生成更有用的错误。
