我得到一个mysql错误：

#update (ActiveRecord::StatementInvalid) "Mysql::Error: #HY000Got error 139 from storage engine:

尝试使用长度为 1429 个字符的字符串更新记录上的文本字段时，有关如何追踪问题的任何想法？

下面是堆栈跟踪。

当您说文本字段时，它是 VARCHAR 类型还是 TEXT 类型？

如果是前者，那么您不能在该列中存储大于 255 个字符的字符串（使用 UTF-8 开销可能更少）。如果是后者，您最好发布您的架构定义，以便人们可以进一步帮助您。

也许是这个错误：#1030 - Got error 139 from storage engine，但如果您发布应该直接在错误消息之后的查询，它会有所帮助。

这似乎是一个非常奇怪的 mysql 错误，其中文本被截断为 256 个字符（对于文本类型）并且抛出上述错误是字符串为 1000 个字符或更多。将表格列修改为文本再次解决了问题，或者它只是自行修复了..我仍然不确定。

更新：将表类型更改为 MyISAM 解决了这个问题
