更新链接视图时 MS Access 写入冲突

问题描述 投票：0回答：1

我有一个表单（子表单，但不相关），它有一个多表链接表视图作为其记录源。到目前为止，我们在通过表单更新任何列时从未遇到过任何实际问题。我们已将本地 SQL 数据库迁移到 Azure SQL，这意味着我们还必须开始使用适用于 SQL Server 的 ODBC 驱动程序 17。现在，当我们尝试更新任何字段时，我们会收到臭名昭著的写入冲突错误。我已经遇到过很多次这种情况，并且能够通过确保所有位字段都有默认值并且不包含空值来解决。这次，我还在相关表中添加了时间戳字段。

尽管如此，我仍然收到写入冲突错误。我有另一个表单，以单个表视图作为其记录源，我可以毫无问题地更新它。

我没有可能影响此问题的底层代码。我只是尝试更改单个值并尝试使用写入符号提交它。我读过许多建议使用查询而不是直接视图/表绑定的线程，但这已经工作了很多年了，而且查询似乎很难构造，因为它包含 MS Access 不包含的数字连接似乎无法应对。

对于可能导致此问题的原因或任何解决方法有什么建议吗？

编辑2： 实际上，我已经将其剥离回仅包含 tblCard 的视图，但它仍然出现相同的错误

我终于解决了这个问题。由于 Azure SQL 仅是 UTC 日期和时间，因此在插入当前日期时，我将插入和更新存储过程中的所有 GetDate() 实例更改为 SYSDATETIMEOFFSET() AT TIME ZONE 'AUS Eastern Standard Time' 以便所有日期会是一致的。其他应用程序也写入此数据库，并且它遵循它们的时区，但由于存储过程位于 SQL Server 本身内，因此它以 UTC 写入。

出于我仍在试图理解的原因，该视图不喜欢这些日期。我更改了视图以将其格式设置为 dd/MM/yyyy，然后它再次开始工作。
