MySQL only get overall ROLLUP

Question

Performing a WITH ROLLUP when grouping by multiple fields, MySQL returns a rollup row for each group, as well as the overall summary:

CREATE TAB         


        

Answer 1

Try to use a subquery, e.g. -

SELECT * FROM (
  SELECT name, number, COUNT(1) FROM test GROUP BY name, number WITH ROLLUP) t
WHERE name IS NULL OR number IS NULL

You also may want to change NULL values with appropriate texts.
