我有一个名为“ FilesUploaded”的表,该表汇总了上传到访问数据库的所有文件。我想在此处添加一个字段,其中包含来自另一个表的所有错误的计数。
下面是我尝试使用的代码,但是它说不允许这种类型的连接,我不知道还有什么其他方法可以实现此目的。
Call RunSQL("UPDATE FilesUploaded " & _
"LEFT JOIN (SELECT table1.Name_of_Report, Sum(IIf([table1].[ValidityCheck] Like '*Error*',1,0)) AS ErrorCount FROM table1 GROUP BY table1.Name_of_Report) AS temp on temp.Name_of_Report = FilesUploaded.FileName " & _
"SET " & _
"FilesUploaded.[ErrorCount] = temp.ErrorCount " & _
"WHERE FilesUploaded.[FileName] = '" & vFileName & "' ")
有人知道有其他方法可以使用Table1表中的ValidityCheck字段来更新FilesUploaded表吗?

要求其类似的UPDATE...JOIN
为updateable。使用SELECT...JOIN
的汇总查询不是可更新查询。因此,请像SUM
那样考虑domain functions。
此外,考虑存储的查询,并通过QueryDefs在带有参数化的VBA中调用它。请注意使用DSum
来对通配符使用ALIKE
,以防万一您需要在MS Access GUI外部运行查询,例如在无法识别%
的ODBC或OLEDB连接中运行。< / p>
