Is mysqlplus a better adapter than ruby ​​mysql?

Question

I want to know if mysqlplus gem is a better database driver than regular Ruby mysql gem? I used to have some problems in a Rails application, for example: ActiveRecord :: StatementInvalid: Mysql :: Error: MySQL server was gone

Answer 1

MySQL server has gone awaymeans that either the MySQL server crashed the execution of the query or (most often) you sent it a quert, which is more than max_allowed_packet. see http://dev.mysql.com/doc/refman/5.1/en/packet-too-large.html
