Narrative:

Approaching sql while on the GPS 30Z approach; inside the FAF; tower told me to begin circling for runway 12. I complied. Runway 12 was the ATIS-designated runway.as I approached the area somewhat equidistant between the airport and cement plant (vpwam); the tower radioed as follows: 'aircraft X; traffic alert: traffic 12 o'clock and a mile opposite direction not sure what he is doing; 900'; aircraft Y.'in the same time-frame; I saw a target on my aircraft traffic system that appeared to be in extreme proximity to me with '00' altitude displayed. I then responded to the tower; 'I'm climbing like crazy; I don't see him.' I then climbed aggressively to an altitude just under the class D ceiling. The tower then instructed the other aircraft to continue on its present heading.I saw the aircraft shortly after -- it must have passed below me. I also communicated that I then saw the other aircraft and was then descending. The tower told aircraft Y to 'continue your present heading.' I then landed uneventfully.upon further reflection and query; aircraft Y had been instructed to continue upwind until I was to have passed; before authorizing him to turn left. Clearly aircraft Y failed to adhere to tower instructions; and also failed to respond to a subsequent radio call from the tower. It was so acute that the tower even radioed aircraft Y; 'aircraft Y; where are you going?'the other pilot appeared to be a highly inexperienced; untrained (and unable to comply). I later phoned the tower; received confirmation that the above situation was accurate; and (non-exclusively) offered to the tower to counsel the other pilot. I trust the tower will be back to me shortly with the path forward; if any. Also; it might have been helpful for the tower to suggest a responsive action by me (e.g.; climb; descend; or turn). Luckily my instincts appear to have been non-hazardous.
