Cause:
First delete the user, then create the user, execute the SQL:

 create user yong@localhost identified by '111111'

Exception:

ERROR 1396 (HY000): Operation CREATE USER failed for 'yong'@'localhost'

Solution:

flush privileges;
drop user yong@localhost;
flush privileges;

The @override annotation in IDEA gives error message “Method does not override Method from its superclass”

Cause of problem:
!! First check to see if the method overloads a parent class. If it doesn’t have a parent class, using @override will get an error.
!!!!!! Check to see if the method name/parameter is different when overloaded;
if none of the above problems exist, it may be the following reasons:
!! There are bugs in IDK5 version of the reference; Override is already available in JDK5, but does not support the implementation of the interface, arguing that it is not override error. JDK6 fixes this bug by annotating either the Override of the parent method or the implementation of the interface with @override.

Error:
STOP: c000021a { Fatal System Error } the initial session process or system process terminated unexpectedly with a status of 0x000000001 (0xc0000034 0x0010038c). The system has been shut down
What went wrong:
Windows7 automatic upgrade to windows10, restart the computer after the beginning of the first step “file copy” process, because to be eager to use the computer, but the replication speed is very slow, waited for almost three minutes to copy 1%, the operation interface and there is no return or undo options, so I decided to force a shutdown. Then the tragedy, boot again, after the display of boot animation will enter the blue screen mode, blue screen display error as above.
try safe mode entry and system recovery will not work, keep going into this terrible blue screen mode.
this is obviously a software error, not hardware related. And the system handler error (abnormal termination), copy 1%, the problem should not be serious.
through PE, can enter the disk and access all the contents of the system disk.
Check the files under the system32 directory of the system disk, found that not many files have been changed, the generated log files are not affected, and several files under C:\Windows\System32\config have been changed.
Solutions:
Copy C:\Windows\System32\config\RegBack to C:\Windows\System32\config

when installing WPS, maybe the system is Windows English monolingual package, not only to set the display language to Chinese, but also the control panel -> Region and language -& GT; Change the system area.

if not changed, some programs can be installed, but the installation interface is all messy code

SQL Sever remote computer rejects network connection. Error: 1225.
This problem is very common, and the solution steps are very simple. For the convenience of my colleagues who are just beginners like me, the steps are specially illustrated and recorded. The following is the specific operation.
 
First, press the shortcut key: CTRL+SHIFT+ESC to open the task manager as shown below.

 
Second, select the Service option in the options bar at the top.

 
The third step is to find the SQL instance (the one you named before) and find that the state is “stopped”.

Step 4: Right click “Stop”, a drop-down appears, and select the “Start” option. Upon completion, the status is displayed as “Running”.

Step 5, restart SQL Sever, the connection can be used normally.

“Sub-process/usr/bin/ DPKG returned an error code(2)
” will not be able to uninstall the plug-in and install
Solution: Go to this path /var/lib/dpkg/(you can use Filza, or connect to your computer to use an assistant), change the file name in the red box to: “Available” and rename it to “available-bak”; Rename the “status” to “status-BAK”, rename the “available” to “available”, and rename the “status-old” to “Status”. If you don’t have any files, you don’t need to change them. Reopen Cydia.
If it is found that such errors still occur
 

Error. JPG
Enter the path of /var/lib/ DPKG /updates/ directory to delete all the files, (backup files are recommended before operation) enter the path of /var/lib/ DPKG/then change the “available-bak” file to “available”, reopen Cydia to solve! .

code is as follows:

require_once ‘.. /pd_inc/pd_mysqlHelper.class.php’;

$prov = array ();

$my = new mysqlHelper();

$my-> Execute_dml (‘ use city);

$query = $my – & gt; Execute_dql (” call pd_seek_city (1, 0, null, null);” );

the while ($res = $query – & gt; fetch_assoc()){

$prov [] = $res;

}

When doing GTI operations over HTTPS, a problem arises when pushing the command:
The requested URL returned error: 403 Forbidden while accessing
Unable to push their own application. After some searching and testing, here is the simplest solution:
On the command line, change the address of the remote repository and add your user name to the front of the address:

git remote set-url origin https://[email protected]/user/repo.git

As my original origin address is: https://github.com/shincling/Initial_test_02.git
At this point becomes: https://[email protected]/shincling/Initial_test_02.git

And then if you Push, git, Push origin master, it will pop up and it will ask you for your password

You can actually just add the password to origin and just Push it
