This is a generated query in a web form where there could be a series of 12 digit event IDs input by the user, hence using the 'in' form. This is slightly lazy programming on my part, but it makes little difference in either PostgreSQL or MySQL whether I use = or 'in'.

If so, I understand why it is like it is. Otherwise, why not make
it a direct equality?
