Show names of technicians who are assigned to repair machines with value point more than 70, and count them by a bar chart, and I want to display from high to low by the X.
SELECT Name, COUNT(Name) FROM repair_assignment AS T1 JOIN machine AS T2 ON T1.Machine_ID = T2.Machine_ID JOIN technician AS T3 ON T1.technician_id = T3.technician_id WHERE T2.value_points > 70 GROUP BY Name ORDER BY Name DESC
SELECT "Name", COUNT("Name") FROM "repair_assignment" "T1" JOIN "machine" "T2" ON "T1"."Machine_ID" = "T2"."Machine_ID" AND "T2"."value_points" > 70 JOIN "technician" "T3" ON "T1"."technician_id" = "T3"."technician_id" GROUP BY "Name" ORDER BY "Name" DESC
