PHP MYSQL group ranking query

Question

CREATE TABLE `players` (
 `pid` int(2) NOT NULL AUTO_INCREMENT,
 `name` varchar(50) NOT NULL,
`team` varchar(20) NOT NULL,
`age` int(2) NOT NULL,
PRIMARY KEY (`pid`)         


        

Answer 1

You need to move the where clause inside the query as

SELECT pid, 
name, 
age, 
team, 
rank 
FROM (
 SELECT pid, name, age, team,
 @curRank := IF(@prevRank = age, @curRank, @incRank) AS rank, 
 @incRank := @incRank + 1, 
 @prevRank := age
 FROM players p, (SELECT @curRank :=0, @prevRank := NULL, @incRank := 1) r
 WHERE team='aa'
 ORDER BY age DESC
) s
