sql计数的agrouped列的总和

Question

I know im asking a silly question, but need a efficient answer: here is my sql:

"SELECT STATUS, COUNT(STATUS) FROM CONTENT GROUP BY STATUS

  +------------+---------------+
  | STATUS     | COUNT(STATUS) |
  +------------+---------------+
  | Converted  |          4547 |
  | Received Q |           525 |
  | Signed     |             1 |
  | Uploaded   |            15 |
  +------------+---------------+

The result is absolutely fine but i need he total or sum of the count(Status) too like 4547+525+1+15 sum up, but how can i do that with easy solution as in my db i have millions of data.

Thanks

Answer 1

您可以使用rollup https://dev.mysql.com/doc/refman/5.0/en/group-by-modifiers.html

SELECT STATUS, COUNT(STATUS) FROM CONTENT GROUP BY STATUS WITH ROLLUP

Answer 2

We can do this by using result from the main query as inner query. Though this is little dummy way of doing this.

    SELECT STATUS, STATUS_COUNT, SUM(STATUS_COUNT) AS TOTAL FROM (SELECT STATUS, COUNT(STATUS) AS STATUS_COUNT FROM CONTENT GROUP BY STATUS) AS X
