$bb=M('Bb') //$aa=M('Aa') $cc=M()都一样
$result=$bb->field('aa.title,bb.name')
->table(array('a_aa'=>'aa','a_bb'=>'bb'))
->limit(20)
->select();结果array(20) {
[0] => array(2) {
["ti
["name"] => string(10) "pageHeader" (一样)
}
[1] => array(2) {
["ti
["name"] => string(10) "pageHeader"
}
[2] => array(2) {
["ti
["name"] => string(10) "pageHeader"
}
......
[9] => array(2) {
["ti
["name"] => string(10) "pageHeader"
}
[10] => array(2) {
["ti
["name"] => string(10) "pageHeader"
}
[11] => array(2) {
["ti
["name"] => string(10) "pageFooter" (到这才不一样,下面又重复,n次以后才不一样)
}
[12] => array(2) {
["ti
["name"] => string(10) "pageFooter"
}
...........
}

SHOW COLUMNS FROM `a_aa` [ RunTime:0.0023s ]
SHOW COLUMNS FROM `a_bb` [ RunTime:0.0025s ]
SELECT aa.ti
