A requirement arises in many systems to update multiple SQL database rows. For small numbers of rows requiring updates, it can be adequate to use an UPDATE statement for each row that requires an update.

In June the NET-A-PORTER Labs team volunteered their services at Edit Amplify’s “Youth Tech” event hosted at the Google Campus, London. Leaders in the fields of Technology, Digital and Design were invited to share an insight into their day-to-day work with 13-14 year old students from Little Ilford High School in Newham. The aim of the event was to excite students about a career in technology, offer an opportunity to talk directly to employers and help inform their course choices over the coming years.
