This article mainly shows you the "getdata table tabular data join mysql method example analysis", the content is easy to understand, clear, hope to help you solve doubts, the following let Xiaobian lead you to study and learn "getdata table tabular data join mysql method example analysis" this article.

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']) {/ / when online ordering is opened, $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;}

Example 1:

$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']; / teacher module ID $tid=$_ M [form] [' tid']; / teacher login user ID $tn=$_ M [form] ['tn']; / / teacher user name $term1 = $_ M [form] [' search_title'] / / get the search keywords $search2 = $term1?

Example 2: 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']; / teacher module ID $tid=$_ M [form] [' tid']; / teacher login user ID $tn=$_ M [form] ['tn']; / / teacher user name $term1 = $_ M [form] [' search_title'] / / get the search keywords $search2 = $term1? "and username like'% {$term1}%'":''; / / add the query registration form number $table = load::sys_class ('tabledata',' new'); / / $where = "lang='cn' {$search} {$search2}"; / / add the query condition $search $u = $_ M ['table'] [' user'] to the conditional statement / / $o = $M ['table'] [' shopv2_order']; $a = $_ M ['table'] [' my_application']; / / $d = $u.'

" 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) / $time=date ('Y-m-d Hpurs) Foreach ($array as $key = > $val) {/ / member group $rs_user_group=DB::get_one ("SELECT id,name FROM". $_ M ['table'] [' user_group'].

Note:

1. List all the data

$data = $this- > table- > getdata ($table,'*', $where, $order)

2. List only the specified field data

$array = $table- > getdata ($d, "{$u} .username, {$u} .groupid", $where, $order)

3. Fuzzy query

$where = "{$u} .lang ='{$_ M ['lang']}' and {$u} .username like'% {$term1}%'"; the above is all the contents of the article "sample Analysis of getdata table tabular data join mysql methods".
