By taking a MySQL structure dump of the database and doing a text search on the dump file, I was able to find a reference to the function calculateGP. This is an alternative way to find references in the database without running a MySQL query.

I will do this:

SELECT TABLE_NAME
FROM INFORMATION_SCHEMA.VIEWS
WHERE VIEW_DEFINITION LIKE '%`calculateGP`%'

If your table, column, or other identifier is also named calculateGP, this may find the wrong match.
