Hi! count function problem.
here is my tb structure.
CREATE TABLE `test` (
`id` int(2) NOT NULL auto_increment,
`r1` varchar(100) NOT NULL default '',
`r2` varchar(100) NOT NULL default '',
PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1 AUTO_INCREMENT=5 ;
records are
id r1 r2
1 a s
2 r a
3 a s
4 a y
How do find count(r1) and count(r2) where r1=a, r2=s
output look like this.
count of a in r1(3) count of s in r2 (2)
