public function get_stop_flag_voucher()
{
//$where['stop_flag'] = 'Y';
//$where['voucher_type'] = array('exp','in (select voucher_type from ebs_vr_ctl)');
//return $this->field("lower('v_' + voucher_type) as voucher_type")->where($where)->select();
$sql = "SELECT lower('v_' + voucher_type) as stop_voucher FROM app_voucher_type WHERE stop_flag = 'Y' AND voucher_type in (select voucher_type from ebs_vr_ctl) ";
return $this->query($sql);
}上述代码，直接在navicat mysql里运行没问题。可是通过tp3.2.2运行，结果得不到正确的结果：array(52) {
[0] => array(1) {
["stop_voucher"] => string(1) "0"
}
[1] => array(1) {
["stop_voucher"] => string(1) "0"
}
[2] => array(1) {
["stop_voucher"] => string(1) "0"
}
[3] => array(1) {
["stop_voucher"] => string(1) "0"
}
[4] => array(1) {
["stop_voucher"] => string(1) "0"
}
[5] => array(1) { 最佳答案
