public function json_product_list($where, $order){
global $_M;
$this- table = load::sys_class( tabledata , new
$p = $_M[table][ product
$s = $_M[table][ shopv2_product
if($_M[ config][shopv2_open]){// 开启在线订购时
$table = $p. Left JOIN .$s. ON ({$p}.id = {$s}.pid)
$where = {$p}.lang= {$_M[ lang]} and ({$p}.recycle = 0 or {$p}.recycle = -1 ) {$where}
}else{
$table = $p;
$where = lang= {$_M[ lang]} and (recycle = 0 or recycle = -1) {$where}
}
$data = $this- table- getdata($table, * , $where, $order);
foreach($data as $key= $val){ if(!$val[ pid])$data[$key][pid] = $val[ id
}
return $data;
}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(){
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
$search2 = $term1 ? and username like %{$term1}% : // 增加查询报名表编号
$table = load::sys_class( tabledata , new
//$where = lang= cn {$search} {$search2} // 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

$list[] = {$rs_user_group[ name]}
$list[] =
$list[] =
$list[] =

$list[] =
$list[] =
$list[] =
$list[] = a > 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
$search2 = $term1 ? and username like %{$term1}% : // 增加查询报名表编号
$table = load::sys_class( tabledata , new
//$where = lang= cn {$search} {$search2} // 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);

$list = array();
$list[] = {$val[ username]}
$list[] = {$rs_user_group[ name]}
$list[] =
$list[] =
$list[] =
$list[] =
$list[] =
$list[] =
$list[] =
$list[] = a > 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}% 以上是“getdata table 表格数据 join mysql 方法的示例分析”这篇文章的所有内容，感谢各位的阅读！相信大家都有了一定的了解，希望分享的内容对大家有所帮助，如果还想学习更多知识，欢迎关注丸趣 TV 行业资讯频道！
