Please tell me how many employees in the department 80 on each type of job titles using a bar chart, and list in desc by the X-axis please.
SELECT JOB_TITLE, COUNT(JOB_TITLE) FROM employees AS T1 JOIN jobs AS T2 ON T1.JOB_ID = T2.JOB_ID WHERE T1.DEPARTMENT_ID = 80 GROUP BY JOB_TITLE ORDER BY JOB_TITLE DESC
SELECT "JOB_TITLE", COUNT("JOB_TITLE") FROM "employees" AS "T1" JOIN "jobs" AS "T2" ON "T1"."JOB_ID" = "T2"."JOB_ID" WHERE "T1"."DEPARTMENT_ID" = 80 GROUP BY "JOB_TITLE" ORDER BY "JOB_TITLE" DESC NULLS LAST
