Peter, Thanks you - I looked up Insert_ID() in the manual... Page 171-172 If I insert into person but before I insert into short, someone else inserts into person, surely my inserts into shirt will have their last Insert_ID()?
Do you know if this is true only in the same connection context only? Or does insert_id() return another connections last insert?
