Hey Guys, I found the mistake I made, basically I'm using a tool called Sentry to capture the exceptions. The value returned from the Python is 2^64-1, which is -1 from mysql_affected_rows. Sentry is using JSON format as the a kind of storage, apparently the MAX SAFE INTEGER <https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Number> is 2^53 -1.
Sorry for the indeliberated report of this issue and thanks for all of you helps. On Sat, Jul 23, 2016 at 12:06 AM, Tian JiaLin <himurakenshi...@gmail.com> wrote: > Yes, you are right.
