MQ Views What are MQ Views? What can they do?

Warnings! SirsiDynix considers MQ Views to be custom work. Thus, if you mess up, they’ll probably charge you to fix the problem. If possible, test your custom views in a “training” or “test” database before changing the production Horizon database. SirsiDynix recommends making sure that your custom MQ Views are read only. Don’t change existing SirsiDynix views. Instead, copy them and then create alternative view sets.

Creating an MQ View from Scratch Creating an SQL View – pt 1 Before creating an SQL View be aware that... SirsiDynix will not support any custom SQL views you create or tables/views you accidentally delete. You should be comfortable creating SQL queries You will need SQL Advantage or some other program to connect to your database.
