我要做的是从RPT_CLAIM_MD_COMBO表中获取所有用户。第一次检查他们的年龄。如果用户的生日的DY> 2015/07/01的DY然后将他的年龄减少1，否则保持相同的年龄。

计算年龄后，我必须根据年龄（i，e组按年龄）显示支出。我编码了这么多，我收到了这个错误 消息329，级别16，状态1，行21每个GROUP BY表达式必须包含至少一个列引用

您无法分配这样的变量。此外，重点是什么？你在哪里使用那个变量？只需删除public class MapsActivity extends FragmentActivity implements LocationListener { GoogleMap mGoogleMap; ArrayList<LatLng> mMarkerPoints; double mLatitude = 0; double mLongitude = 0; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_maps); // Getting Google Play availability status int status = GooglePlayServicesUtil.isGooglePlayServicesAvailable(getBaseContext()); if (status != ConnectionResult.SUCCESS) { // Google Play Services are not available int requestCode = 10; Dialog dialog = GooglePlayServicesUtil.getErrorDialog(status, this, requestCode); dialog.show(); } else { // Google Play Services are available // Initializing mMarkerPoints = new ArrayList<LatLng>(); // Getting reference to SupportMapFragment of the activity_main SupportMapFragment fm = (SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map); // Getting Map for the SupportMapFragment mGoogleMap = fm.getMap(); // Enable MyLocation Button in the Map if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) { // TODO: Consider calling // ActivityCompat#requestPermissions // here to request the missing permissions, and then overriding // public void onRequestPermissionsResult(int requestCode, String[] permissions, // int[] grantResults) // to handle the case where the user grants the permission.
