使用group报错

Mysql环境是5.7的, 使用了View进行了表连接, 进行了表连接

搬迁到本地后, 查询报错 Syntax error or access violation: 1055 Expression

解决方法1

配置 my.cnf(linux)文件 win下面是 mysql.ini文件

在 mysqld 里加上

sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES

重启mysql即可

解决方法2

在不修改MySQL配置文件的情况下，需要修改sql语句来执行。

group by后面的列名，还是和以前一样通过select直接获取，而对于select中获取非group by的信息，则要通过any_value()函数。
例如：

// 筛选商家服务范围包含当前选择小区的商家
$subQuery  = FuwuModel::where(function ($query) use ($houseRow){$query->where(function ($query) use ($houseRow){$query->where(['level' => 'province','province_id' => $houseRow['province_id']]);})->whereor(function ($query) use ($houseRow){$query->where(['level' => 'city','province_id' => $houseRow['province_id'],'city_id' => $houseRow['city_id']]);})->whereor(function ($query) use ($houseRow){$query->where(['level' => 'district','province_id' => $houseRow['province_id'],'city_id' => $houseRow['city_id'],'district_id' => $houseRow['district_id']]);})->whereor(function ($query) use ($houseRow){$query->where(['level' => 'street','province_id' => $houseRow['province_id'],'city_id' => $houseRow['city_id'],'district_id' => $houseRow['district_id'],'street_id' => $houseRow['street_id']]);})->whereor(function ($query) use ($houseRow){$query->where(['level' => 'house','province_id' => $houseRow['province_id'],'city_id' => $houseRow['city_id'],'district_id' => $houseRow['district_id'],'street_id' => $houseRow['street_id'],'house' => $houseRow['houseid']]);});})->field("any_value(shop_fuwu_id) as shop_fuwu_id,shop_id")->group('shop_id')->buildSql();$top_shop = $manystoreShop->alias('m')->join("$subQuery f", 'm.id = f.shop_id')->where('m.shop_status','10')->where('m.shop_tab','1')->field('id,logo,songdatag_id,name')->order('weigh desc')                        ->limit(5)->select();
