How to Resolve Trigger Results Error in MySQL

MySQL uses many advanced operations to manage databases. It uses different types of processes for different purposes and these processes are called triggers. For example an insert trigger gets activated whenever a row is inserted inside SQL table, an updating trigger is initialized when a value is updated inside a table and delete trigger gets activated whenever a value is deleted inside a table. When triggers are used with the applications that do not have the ability to get back data in return this can inevitably cause trigger result set errors.

    To perform a successful solution, you need to set the value of disallow trigger to ON in your MySQL server options. To do this set the values in your MySQL server’s option as follows:

    sp_configure 'show advanced options', 1

    reconfigure

    sp_configure 'disallow results from triggers', 1

    reconfigure

    The above configuration will catch any result set error caused by the triggers and will not show you error message in return hence will stop unexpected behaviour.
