Answer 1

Use GROUP BY and then SUM(condition) to obtain your counts:

SELECT   name AS Name,
         SUM(type     = 'worker' ) AS Worker,
         SUM(type     = 'student') AS Student,
         SUM(type     = 'adult'  ) AS Adult,
         SUM(sales    = 'A'      ) AS A,
         SUM(sales    = 'B'      ) AS B,
         SUM(sales    = 'C'      ) AS C,
         SUM(sales    = 'D'      ) AS D,
         SUM(location = 1        ) AS Location1,
         SUM(location = 2        ) AS Location2,
         SUM(location = 3        ) AS Location3,
         SUM(location = 4        ) AS Location4
FROM     sales
GROUP BY Name
