ERROR 1665 (HY000): Cannot execute statement: impossible to write to binary log since BINLOG_FORMAT = STATEMENT and at least one table uses a storage engine limited to row-based logging. InnoDB is limited to row-logging when transaction isolation level is READ COMMITTED or READ UNCOMMITTED.

【报错原因】
innodb的事务隔离级别是read commited或者read uncommited模式时，binlog不可以使用statement模式。

【解决办法】
方法1：不重启mysql服务
set global binlog_format=mixed 重新建立的会话中BINLOG_FORMAT会变为mixed模式。
参考mysql错误处理之ERROR 1665 (HY000)
方法2：重启mysql服务
把my.cnf中binlog_format改为混合模式：

# binary logging format - mixed recommended
binlog_format=mixed

参考ERROR 1665 (HY000): Cannot execute statement: impossible to write to binary log since BINLOG_FORMAT
