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.

If Horizon didn’t provide a translation for dates and other fields, the date for an item created on April 7, 1988 would appear as the number 6671 instead of a human readable date like 04/07/88.

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.


Example SQL Query

SELECT isbn,bib#, count(*) duplicates FROM isbnex_inverted GROUP BY isbn HAVING count(*) > 1


Syntax of an SQL View

CREATE VIEW [view name you pick] AS[select statement you created previously]

Example Creation of a View

CREATE VIEW isbn_duplicates_gs AS SELECT isbn,bib#, count(*) duplicates FROM isbnex_inverted GROUP BY isbn HAVING count(*) > 1


Granting Permissions for Horizon Users to See the View

GRANT ALL ON [view name you picked] TO[user group]

Example:

GRANT ALL ON isbn_duplicates_gs TO staffgroup

IMPORTANT

•Do not drop an SQL View or delete a MQ View unless you know EXACTLY what you are doing. Dropping or deleting an incorrect view can cause Horizon to stop functioning.


Syntax of dropping an SQL View

DROP VIEW [view name you pick]

Example Dropping an SQL View

DROP VIEW isbn_duplicates_gs
