我有2张桌子
它拥有的第一台演员
ID name_english picture link
5 Daniela Bessia 4f8ab755ed.png daniela-bessia
6 Mohannad Alarjan 14f8dfsf55ed.png mohannad-alarjan
7 Lee Tae-Im kxe3gj64.jpg lee-tae-im
第二个表actors_content
id content_id actors_id
1 7 5
2 5 5
3 5 6
4 5 7
现在我的查询是按戏剧ID请求的,如果访问者访问的戏剧ID为7(content_id),则应该在第二个表actors_content上进行搜索,并选择所有要成为content_id = 7的数据,我希望一一加入而对于没有重复数据的演员数据,可以从演员那里获取演员详细信息
public function dodisplayActorsbycontent($getid){
$query = $this->db->query("SELECT `actors`.`id` , `actors`.`name_english` , `actors`.`picture` , `actors`.`link` , `actors_content`.* FROM `actors_content`, `actors` WHERE `actors_content`.`content_id` = '".$getid."'");
$total = $this->db->resultcount($query);
if($total != 0){
while($this->db->fetchrow($query)){
$list[] = $this->db->_record;
}
return($list);
}else{
return(false);
}
}

联接需要一个function testPostgres(){
const moment = require('moment-timezone')
const Client = require('pg-native')
const client = new Client()
client.connect('postgres://postgres:postgres@host:5432/postgres', function(err) {
if(err) throw err
const moment1 = moment()
for (let i = 0; i < 1000; i++) {
let rows = client.querySync('update json_test set data = data || \'{"SkillChance": 1}\', count =count+1 where id =$1',[1])
}
const moment2 = moment()
const diff = moment2.diff(moment1, 'seconds')
console.log(diff) //
})
}
