Question

我在更新mysql表时遇到问题。虽然问题似乎有些奇怪，但我在下面解释。

我正在处理用户的配置文件更新，其中单个表单中的数据正在插入/更新到两个不同的表但是如果我更新整个表单信息，那么更新数据是成功的但是如果我只更新了一些2或3个字段然后更新失败了。我正在使用mysql存储过程进行sql更新，代码如下...

虽然我用不同的关键字多次搜索我的问题，但我没有找到相关的问题，因为我已经正确地写了更新语句但是没有更新，因为大多数将要更新的新数据与旧的相同我的大四学生说我更新只有在提交和使用新数据集时才有效。

所以，请帮我解决这个问题提前谢谢..

如果我们更新相同的数据，我最近才知道UPDATE语句返回错误。因此，我已更新添加的新列modified_date并使用NOW()更新此字段，以便至少更改了一列，并且UPDATE语句不会返回错误。
