#MYSQL RANK QUERY WINDOWS#
The ranking functions are also part of MySQL windows functions list. This query is simply pulling the highest score for Bob from each quiz - what I want to add is the ranking of the score among the scores in that particular quiz - so an output like the following:īob's rank is '2' for the math quiz as Steve has a higher score, but he is ranked '1' for reading as he has the highest score. The RANK and DENSERANK functions allow you to calculate the rank, or the position in a list, of a value in a group of values. The ranking functions in MySQL are used to rank each row of a partition. SELECT `user`, `score`, `quiz_id` FROM `allscores` WHERE `user`="Bob" AND `high_score`="1" What I want is a SQL query that I can run on an individual user to pull their highest score from each of the two quizzes ('math' and 'reading') along with their overall rank among scores for that quiz. MySQL Numeric Functions COUNT, Returns the number of records returned by a select query DEGREES, Converts a value in radians to degrees DIV, Used for integer. The 'high_score' field is in the table to begin with and is always set to '1' for the row where a user's score is the highest for them for that quiz. I have a large SQL table called 'allscores' similar to the following: Hey all - need help making a query which will return rankings based on multiple columns.
