How count max of a group?

Question

I need a command that would pick out the most count of positive issues from an author, for example, the result should look like this:

Author     WithTheMostMax
Author1                2

AUTHOR TABLE

AuthorID    AuthorName
Author1    AuthorName1
Author2    AuthorName2
Author3    AuthorName3

ISSUES LIST

AuthorID    Issues
Author1          1
Author2          0
Author3          0
Author1          1

Answer 1

SELECT AuthorName, SUM(Issues) AS WithTheMostMax FROM issues_list INNER JOIN issues_list.AuthorID = author_table.AuthorID
GROUP BY AuthorName ORDER BY SUM(Issues) DESC

Answer 2

You can use count() if 1 issue per author is stored in each row in issues table.

SELECT `authors`.`authorID`, COUNT(`issues`) as `maxIssues`
FROM `issues_list` INNER JOIN `authors` ON   
`issues_list`.`authorID`=`authors`.`authorID`
WHERE `issues`>0
GROUP BY `issues_list`.`authorID`
ORDER BY `maxIssues` DESC
