  • Error Code : 1064 You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'order LIMIT 0, 1000' at line 1

    今天在查询数据的时候遇到这个错误,特别的郁闷,感觉自己写的sql语句没有问题啊,但就是提示我的sql语法错误,后来终于找到了原因

    该错误一般出现在表名或字段名设计的过程中出现了mysql关键字导致的。

    如果你用了mysql中的关键字做字段,当你查询的时候可以用  `order` 来括起来,这个 ` 并不是单引号,而是数字那一行键的最左边的那个键,在英文状态下的才为 ` ,用它把关键字括起来就可以解决这个问题。

  • MySQL Error Code:1093,Error Code:1248

    Error Code:1093 是在执行DELETE或者UPDATE时含有子查询导致的。 You can't specify target table 'USER' from update in FROM clause 如: UPDATE user SET usex = 4 WHERE uage>(SELECT AVG(uage) ...

    Error Code:1093 是在执行DELETE或者UPDATE时含有子查询导致的。

    You can't specify target table 'USER' from update in FROM clause

    如:

    UPDATE user SET usex = 4 WHERE

    uage>(SELECT AVG(uage) FROM user);

    可修改为:

    UPDATE user SET usex = 4 WHERE

    uage>(SELECT avg_uage FROM (SELECT AVG(uage) AS avg_uage FROM user) AS tmpuser);

    Error Code:1248:

    如果不在子查询后加别名AS tmpuser会报1248错误。

    参考: MySQL更新时Error Code:1093和Error Code:1175的解决办法

          最近蓝牙手环在Android9.0的手机上回连总是连接不上,老在扫描的地方onScanFailed里回调errorCode=2,errorCode共有下面4种情况:

    errorCode=1;Fails to start scan as BLE scan with the same settings is already started by the app.
    errorCode=2;Fails to start scan as app cannot be registered.
    errorCode=3;Fails to start scan due an internal error
    errorCode=4;Fails to start power optimized scan as this feature is not supported

           发现BluetoothGatt.close()不管用,关闭重启手机蓝牙或者重启App是可以重新连接蓝牙,但是咱不能一碰到这个问题就让用户去重启App或者重启手机蓝牙。经过查阅各种资料,说问题的原因是:

           手机在startScan扫描的过程中还没来得及stopScan ,就被系统强制杀掉了, 导致mClientIf未被正常释放,实例和相关蓝牙对象已被残留到系统蓝牙服务中, 打开app后又重新初始化ScanCallback多次被注册,导致每次的扫描mClientIf的值都在递增, 于是mClientIf的值在增加到一定程度时(最大mClientIf数量视国产系统而定 不做深究),onScanFailed 返回了 errorCode =2  。

         解决办法是:重新刷新手机的蓝牙状态

        public static boolean releaseAllScanClient() {
            try {
                Object mIBluetoothManager = getIBluetoothManager(BluetoothAdapter.getDefaultAdapter());

            declaredMethod.setAccessible(true);
            return declaredMethod;
        }

     

    调用上面的反射还不行,因为Android9.0对SDK的反射会抛出异常,弹出下面的警告窗口:

    所以需要在App初始化的时候调用下面的反射来关闭Android9.0的弹窗:

    @SuppressLint("PrivateApi")
    private void closeAndroidPDialog(){
        try {
            Class aClass = Class.forName("android.content.pm.PackageParser$Package");
            Constructor declaredConstructor = aClass.getDeclaredConstructor(String.class);
            declaredConstructor.setAccessible(true);
        } catch (Exception e) {
            e.printStackTrace();
        }
        try {
            Class cls = Class.forName("android.app.ActivityThread");
            Method declaredMethod = cls.getDeclaredMethod("currentActivityThread");
            declaredMethod.setAccessible(true);
            Object activityThread = declaredMethod.invoke(null);
            Field mHiddenApiWarningShown = cls.getDeclaredField("mHiddenApiWarningShown");
            mHiddenApiWarningShown.setAccessible(true);
            mHiddenApiWarningShown.setBoolean(activityThread, true);
        } catch (Exception e) {
