Yuniql fails on a MariaDB script that contains session variables

[svegasoft]

Yuniql fails on this script:

BEGIN NOT ATOMIC
   select now() into @date;
   select @date;
END

This script runs normally in MariaDB. Replacing session variable with a local one fixes the issue.
It is necessary for Yuniql to support session variables because session variables are the only way to execute dynamic sql.
