VBA-Access：我的一些插入查询有效，其他查询无效，我的最终更新查询也无效。我究竟做错了什么？

Question

这里是代码。因为我真的只是想让它在这一点上工作，所以这一切都直接在点击事件中。我没有收到任何错误。它只是没有完全工作：

我已经包含了几个 msgbox，它们都显示了我保存在各种变量中的正确信息，所以我不知道为什么它在我运行更新查询时不起作用，至少。我对从 VBA 填充数据库还很陌生，所以我想这与我使用访问数据库的方式有关。我也怀疑我的约会是个问题，但我不知道为什么。任何帮助，将不胜感激。

Answer 1

"SELECT @@Identity"

不是Access SQL，所以用一些值替换它，或者如果该字段是自动编号，则将其完全删除。

Answer 2

我终于明白了。我只需要使用 TempVars 集合。我不明白为什么这是必要的，但显然这是从插入访问存储在标识值中的变量的方法。

我能够像这样保存变量：

TempVars("tempTaskId").Value = taskId

然后像这样在查询中访问它：

TempVars!tempTaskId.Value
