How does one handle ties when ranking results in a mysql query? I've simplified the table names and columns in this example, but it should illustrate my problem: SET @rank=0; SELECT student_names.students, @rank := @rank +1 AS rank, scores.grades FROM student_names LEFT JOIN scores ON student_names.stude...

I was playing with the Stack Exchange Data Explorer and ran this query: http://odata.stackexchange.com/stackoverflow/q/2828/rising-stars-top-50-users-ordered-on-rep-per-day Notice down in the results, rows 11 and 12 have the same value and so are mis-numbered, even though the row_number() function takes the same order by parameter as th...
