Yii2连接PostgreSql的方法

1、配置连接postgresql的连接信息：

$dev = [
    &＃39;class&＃39;    => &＃39;yii\db\Connection&＃39;,
    &＃39;dsn&＃39;      => &＃39;pgsql:host=122.112.182.211;port=8000;dbname=sdk_info&＃39;,
    &＃39;username&＃39; => &＃39;dbadmin&＃39;,
    &＃39;password&＃39; => &＃39;Styl2018@&＃39;,
    &＃39;charset&＃39;  => &＃39;utf8&＃39;,
//    &＃39;emulatePrepare&＃39; => true
];
return $dev;

2、Yii2目录下，models目录下新建model：

class TestSdkVsent extends Base
{
    public static function getDb()
    {
        return \Yii::$app->dbDws;
    }
    public static function tableName()
    {
        return &＃39;sdk_info.tb_sdk_vsent&＃39;; // TODO: Change the autogenerated stub
    }
    public static function test()
    {
        $find = static::find();
        $result = $find->select(&＃39;rtt&＃39;)->limit(1) ->asArray()->one();
        return $result;
    }
}

3、备注：

$result = $find->select(&＃39;rtt&＃39;)->limit(1)->asArray()->one(); 查询到一条数据返回

解析结果：``SELECT * FROM "sdk_info"."tb_sdk_vsent" LIMIT 1

$result = $find->select(&＃39;rtt&＃39;)->asArray()->one(); 会查询所有的数据返回一条

解析结果：SELECT "rtt" FROM "sdk_info"."tb_sdk_vsent"
