BIRT报告错误列绑定

Question

我有一份BIRT报告，在我改变连接的数据库之前一直工作正常。我从数据库中的表中删除了一列，并在我的数据查询中删除了对它的任何调用，现在每当我尝试生成BIRT报告时，我都会收到此错误。

The following items have errors: 

Data (id = 291): 
+ Column binding "isComplete_18" has referred to a data set column "isComplete_18" which does not exist. (Element ID:291) 

Data (id = 298): 
+ Column binding "isComplete_18" has referred to a data set column "isComplete_18" which does not exist. (Element ID:298) 

Data (id = 292): 
+ Column binding "isComplete_18" has referred to a data set column "isComplete_18" which does not exist. (Element ID:292) 

Data (id = 299): 
+ Column binding "isComplete_18" has referred to a data set column "isComplete_18" which does not exist. (Element ID:299) 

Data (id = 293): 
+ Column binding "isComplete_18" has referred to a data set column "isComplete_18" which does not exist. (Element ID:293) 

Data (id = 300): 
+ Column binding "isComplete_18" has referred to a data set column "isComplete_18" which does not exist. (Element ID:300) 

Data (id = 585): 
+ Column binding "isComplete_18" has referred to a data set column "isComplete_18" which does not exist. (Element ID:585) 

Table (id = 443): 
+ Column binding "name_19" has referred to a data set column "name_19" which does not exist. (Element ID:443) 

Data (id = 583): 
+ Column binding "isComplete_18" has referred to a data set column "isComplete_18" which does not exist. (Element ID:583) 

谷歌搜索没有出现太多其他未解决的问题，我不知道如何继续。我已经在phpmyadmin中测试了查询，它返回了预期的结果，但是在BIRT中我什么都没得到。有什么想法吗？

Answer 1

您很可能在报告XML文件中引用了已删除的列，转到XML视图并搜索：“isComplete_18”，“name_19”，并删除包含该字符串的每个xml元素。

手动删除对两列的每个引用后，再次重新运行报告...

Answer 2

我遇到过这个问题一次。看来（不完全确切）报告是绑定列，当您更改数据库或更改DataSet上的某些内容时不再存在（对我来说这是第二种情况）。

我试过这个并为我工作：

• 选择你的桌子;
• 转到“Property Editor”;
• 转到“绑定”标签;
• 点击“清除”;
• 选择之前使用的相同数据集;
• 尝试生成报告。

希望它可以帮到你！

Answer 3

转到表格的属性编辑器。然后绑定选项卡。数据列绑定下的绑定仍然链接到您引用的旧列。

Answer 4

我所做的是，在XML源中搜索该元素并将其删除。
