例子一：
$u = $_m['table']['user'];
$o = $_m['table']['shopv2_order'];
$d = $u.' left join '.$o." on {$u}.id = {$o}.uid";
function dotable_course_user_list_json(){

$id=$_m[form]['id'];//教师模块id
$tid=$_m[form]['tid'];//教师登录用户id
$tn=$_m[form]['tn'];//教师用户名
$term1 = $_m[form]['search_title']; //获取搜索关键词
$search1 = $term1 ?"and username like '%{$term1}%' ":'';//增加查询报名表编号
$table = load::sys_class('tabledata', 'new');
//$where = "lang='cn' {$search} {$search1}"; //在条件语句中加入查询条件 $search
$u = $_m['table']['user'];
$o = $_m['table']['shopv2_order'];
$d = $u.' left join '.$o." on {$u}.id = {$o}.uid";
//$table = $u.' left join '.$a." on (find_in_set(u.id,a.user_id) != 0)";
$where = "{$u}.lang='{$_m['lang']}'";
$order = "{$u}.id desc";
$array = $table->getdata($d, '*', $where, $order);
//$data = $this->table->getdata($table, '*', $where, $order)
//$time=date('y-m-d h:i:s',time());
foreach($array as $key => $val){
//会员组
$rs_user_group=db::get_one("select id,name from ".$_m['table']['user_group']." where id='$val[groupid]' ");
//状态
//班型
//$rs1=db::get_all("select s.class_id,a.user_id,a.id,a.number,cc.classhour from ".$_m['table']['my_application']." as a inner join ".$_m['table']['my_application_subject']." as s on a.number=s.number inner join ".$_m['table']['my_class']." as c on s.class_id=c.id inner join ".$_m['table']['my_class_course']." as cc on cc.class_id=c.id where s.class_id<>0 and s.type_11=0 and c.teachers_id='$val[id]' and cc.endtime>'$time'");
$list = array();
$list[] = "{$val['username']}";
$list[] = "{$rs_user_group['name']}";
$list[] = "";
$list[] = "";
$list[] = "";
$list[] = "";
$list[] = "";
$list[] = "";
$list[] = "";
$list[] = "<a class='btn btn-danger view_error' lay-id='{$val['id']}' href='javascript:;'><i class='glyphicon glyphicon-edit'></i> 错题集</a>";
$list[] = "";
$list[] = "";
$rarray[] = $list;
}
// dump($rarray);
$table->rdata($rarray);//返回数据
}
例子二：join find_in_set
$u = $_m['table']['user'];
$a = $_m['table']['my_application'];
$d = $u.' left join '.$a." on find_in_set({$u}.id,{$a}.user_id) != 0";
function dotable_course_user_list_json(){
global $_m;
$id=$_m[form]['id'];//教师模块id
$tid=$_m[form]['tid'];//教师登录用户id
$tn=$_m[form]['tn'];//教师用户名
$term1 = $_m[form]['search_title']; //获取搜索关键词
$search1 = $term1 ?"and username like '%{$term1}%' ":'';//增加查询报名表编号
$table = load::sys_class('tabledata', 'new');
//$where = "lang='cn' {$search} {$search1}"; //在条件语句中加入查询条件 $search
$u = $_m['table']['user'];
//$o = $_m['table']['shopv2_order'];
$a = $_m['table']['my_application'];
//$d = $u.' left join '.$o." on {$u}.id = {$o}.uid";
$d = $u.' left join '.$a." on find_in_set({$u}.id,{$a}.user_id) != 0";
$where = "{$u}.lang='{$_m['lang']}'";
$order = "{$u}.id desc";
$array = $table->getdata($d, '*', $where, $order);
//$data = $this->table->getdata($table, '*', $where, $order)
//$time=date('y-m-d h:i:s',time());
foreach($array as $key => $val){
//会员组
$rs_user_group=db::get_one("select id,name from ".$_m['table']['user_group']." where id='$val[groupid]' ");
//状态
//班型
//$rs1=db::get_all("select s.class_id,a.user_id,a.id,a.number,cc.classhour from ".$_m['table']['my_application']." as a inner join ".$_m['table']['my_application_subject']." as s on a.number=s.number inner join ".$_m['table']['my_class']." as c on s.class_id=c.id inner join ".$_m['table']['my_class_course']." as cc on cc.class_id=c.id where s.class_id<>0 and s.type_11=0 and c.teachers_id='$val[id]' and cc.endtime>'$time'");
$list = array();
$list[] = "{$val['username']}";
$list[] = "{$rs_user_group['name']}";
$list[] = "";
$list[] = "";
$list[] = "";
$list[] = "";
$list[] = "";
$list[] = "";
$list[] = "";
$list[] = "<a class='btn btn-danger view_error' lay-id='{$val['id']}' href='javascript:;'><i class='glyphicon glyphicon-edit'></i> 错题集</a>";
$list[] = "";
$list[] = "";
$rarray[] = $list;
}
// dump($rarray);
$table->rdata($rarray);//返回数据
}
注意：
1、列出全部数据
$data = $this->table->getdata($table, '*', $where, $order)
2、只列出指定字段数据
$array = $table->getdata($d, "{$u}.username,{$u}.groupid", $where, $order);
3、模糊查询
$where = "{$u}.lang='{$_m['lang']}' and {$u}.username like '%{$term1}%' ";
