Re: Not consisent result about mysql_stmt_execute and mysql_stmt_errno.

[hello okay]

Step like this:
1) mysql 8.0.25 client to connect mysql 8.0.18 server.
2) vi /etc/my.cnf, add wait_timeout=60 in mysqld and restart mysql, the purpose is to decrease mysql connection valid time.
3) use script to trigger executing mysql command every two minutes, the result of mysql_stmt_execute may return 1 and mysql_stmt_errno return 0.

Btw, my solution is when mysql_stmt_errno return 0, reconnect mysql again.
