Question

我有这个代码，它在在线服务器上正常工作：

public class MainActivity extends AppCompatActivity implements
    GoogleApiClient.OnConnectionFailedListener,
    GoogleApiClient.ConnectionCallbacks,
    LocationListener {


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        buildGoogleApiClient();
    }

    @Override
    public void onConnected(@Nullable Bundle bundle) {
        Log.d(TAG, "Connection established. Fetching location ..");
        mLocationRequest = new LocationRequest();
        mLocationRequest.setInterval(1000);
        mLocationRequest.setFastestInterval(1000);
        mLocationRequest.setPriority(LocationRequest.PRIORITY_BALANCED_POWER_ACCURACY);

        LocationServices.FusedLocationApi.requestLocationUpdates(mGoogleApiClient, mLocationRequest, this);
    }

    @Override
    public void onLocationChanged(Location location) {

        Log.d("Lat: " + location.getLatitude() + "Lng : " + location.getLongitude());    
        LatLng latLng = new LatLng(location.getLatitude(), location.getLongitude());
    }

    public synchronized void buildGoogleApiClient() {
        mGoogleApiClient = new GoogleApiClient.Builder(getBaseContext())
            .addConnectionCallbacks(this)
            .addOnConnectionFailedListener(this)
            .addApi(LocationServices.API)
            .build();
        mGoogleApiClient.connect();
    }

    @Override
    public void onPause() {
        super.onPause();
        //stop location updates when Activity is no longer active
        if (mGoogleApiClient != null) {
            LocationServices.FusedLocationApi.removeLocationUpdates(mGoogleApiClient, this);
        }
    }
}

但是在localhost上它会出现如下错误：

SELECT
DATE(`order`.`date`) AS `dater`,
COUNT(*) AS `orders-amount`,
SUM(`order`.`price`) AS `orders-income`,
(SELECT SUM(`amount`) FROM `paypal` WHERE `paypal`.`txn_id` != 'Bonus' AND YEAR(`dater`) = YEAR(`paypal`.`posted_date`) AND MONTH(`dater`) = MONTH(`paypal`.`posted_date`)) AS `total_charge`
FROM `order`
GROUP BY YEAR(`dater`), MONTH(`dater`)
ORDER BY `dater` DESC

我使用此代码进行分组，然后才能正常工作：

#1055 - Expression #1 of SELECT list is not in GROUP BY clause and contains nonaggregated column 'panel.order.date' which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode=only_full_group_by

此错误仅出现在localhost上，因为我在linux Mint上运行并安装了apache，php，mysql＆amp; pypmyadmin

Answer 1

这意味着在本地和远程服务器上使用不同的sql模式。您应该更改模式或更新您的查询，如：

SELECT
YEAR(ANY_VALUE(`order`.`date`)) date_year,
MONTH(ANY_VALUE(`order`.`date`)) date_month,
COUNT(*) AS `orders-amount`,
SUM(`order`.`price`) AS `orders-income`,
(SELECT SUM(`amount`) FROM `paypal` WHERE `paypal`.`txn_id` != 'Bonus' AND YEAR(ANY_VALUE(`order`.`date`)) = YEAR(`paypal`.`posted_date`) AND MONTH(ANY_VALUE(`order`.`date`)) = MONTH(`paypal`.`posted_date`)) AS `total_charge`
FROM `order`
GROUP BY date_year, date_month

Answer 2

您的错误消息中包含它：

这与sql_mode = only_full_group_by
不兼容

如果你没有故意设置，我猜你默认得到了它，你在本地服务器上有不同的版本（见here，它在某些时候是默认的。）

所以你需要的是通过运行SET sql_mode='';或按照here

的说明来禁用此模式

在mysql中按年，月分组的错误
