Looking for some MYSQL help.  I have a custom field in the request template to categorise Incident, Service Requests and RFC's.  A certain type of request has been categorised incorrect and I think I could amend this with a SQL update.

It would be something like "update Categorisation to Service Request where Category = X and sub category = Y"

Sounds like I know but I really don't!

Any help with the syntax would be appreciated.

Cheers,
Lee
