Question

我的存储过程有页码的IN参数（IN page INT）一切都适用于任何值<= 2147483647。如果值为> 2147483647，则会收到错误1264。所有这些都发生在5.6.26 Community Server compiled for Linux (x86_64)上，而5.6.24 Community Server compiled for Win64 (x86_64)则相同以上所有都很好，我理解错误。

但是，在服务器5.6.30-1+deb.sury.org~xenial+2 (Ubuntu) compiled for debian-linux-gnu (x86_64)上，这不会被复制。无论我通过什么值，输入值都会减少到2147483647。

这个＆＃34;自动最大值上限＆＃34;是什么设置？如何在不重新安装的情况下同步不同环境中的设置以具有相同的行为？

谢谢！
