When attempting to execute a stored procedure in MySQL through Appian or execute a database query through Appian, the following error is returned:

SQL Message : Statement violates GTID consistency: Updates to non-transactional tables can only be done in either autocommitted statements or single-statement transactions, and never in the same statement as updates to transactional tables.
This error is thrown when at least one of the tables involved is configured to use a nontransactional storage engine such as MyISAM.
According to the MySQL documentation here, "when using GTIDs, updates to tables using nontransactional storage engines such as MyISAM cannot be made in the same statement or transaction as updates to tables using transactional storage engines such as InnoDB."
Use InnoDB instead of MyISAM. Steps on converting MyISAM to InnoDB can be found here.
Update the design of your query/procedure to avoid this issue. For example:
