推荐答案

当您尝试将数值插入/更新到该数据类型范围之外的某些内容时，会导致溢出错误。

不知道架构您的表格以及插入的数据很难回答。提供该信息，我可以更新答案。

Overflow errors are caused when you try to insert/update a numeric value to something outside of that data-types range.
Without knowing the schema of your table as well as the data being inserted, it is hard to answer. Provide that information and I can update the answer.
