   multi statement support by PR #3050.
   But there is a minor issue in implementation.
   
   as MySQL dev doc say in
   
https://dev.mysql.com/doc/dev/mysql-server/latest/page_protocol_command_phase_sp.html#sect_protocol_command_phase_sp_multi_statement
   
   server should only process multi statement
   when client set CLIENT_MULTI_STATEMENTS.
   When client not set CLIENT_MULTI_STATEMENTS, server should treat query as 
single statement.
   
   but Doris do slightly different with MySQL server. Doris always treat query 
as multi statement, but only return multi result when client set 
CLIENT_MULTI_STATEMENTS. When client do not set CLIENT_MULTI_STATEMENTS, Doris 
will return the last statement result only.
