MySQL官方文档中是这样写的: 代码如下: NO_AUTO_VALUE_ON_ZERO affects handling of AUTO_INCREMENT columns. Normally, you generate the next sequence number for the column by inserting either NULL or 0 into it. NO_AUTO_VALUE_ON_ZERO suppresses this behavior for 0 so that only NULL generates the next sequence number. This mode can be useful if 0 has been stored in a table's AUTO_INCREMENT column. (Storing 0 is not a recommended practice, by the way.) For example, if you dump the table with mysqldump and then reload it, MySQL normally generates new sequence numbers when it encounters the 0 values, resulting in a table with contents different from the one that was dumped. Enabling NO_AUTO_VALUE_ON_ZERO before reloading the dump file solves this problem. mysqldump now automatically includes in its output a statement that enables NO_AUTO_VALUE_ON_ZERO, to avoid this problem.
至此问题解决。 后记: 由于业务逻辑需要,在自增列会存在0值,为了在Windows平台和Linux平台的MySQL之间复制数据,增加全局变量设置,在my.ini和my.cnf中分别添加NO_AUTO_VALUE_ON_ZERO设置到sql-mode行,例如: 代码如下: //my.ini 该文件在Windows7或Windows2008操作系统中位于 C:\ProgramData\MySQL\MySQL Server 5.6 目录下(采用MSI安装方式)# Set the SQL mode to strict sql-mode="STRICT_TRANS_TABLES,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION,NO_AUTO_VALUE_ON_ZERO"
