Could you tell me how to deal with this problem in R language?
alter table stu add foreign key(cno) references user(id);
Failed to add the foreign key constraint. Missing index for constraint ‘stu_ibfk_1’ in the referenced table ‘user’
solution:
as the foreign key, user table id must be a unique value, so the constraint unique, or primary key must be added;
I try to remove a Windows Service with sc delete < service name> , and encounter the following error: I try to use sc delete < service name> Windows service, and encountered the following error:

The specified service has been marked for deletion. specified service marked for deletion.
What I ‘ve already done: I have done:
Stopped the service, informational: obviously, service has been Stopped. The sc queryex "< service name>" gives the following result: sc queryex "< service name>" gives the following results:

2 3 Removed the key HKEY_LOCAL_MACHINE\\ \\ \\CurrentControlSet\\ \Services\\< service name> From the registry. deleted from the registry key HKEY_LOCAL_MACHINE \\ \ CurrentControlSet \\ Services \ < Service name & GT; .
Due to this removal, services.msc still shows the service (with a name, but no status or startup type), but the description is “< MSC services.msc still shows the service (with name, but no status or startup type), but described as “< Unable to read description. Error Code: 2 >” . error code: 2>” . When we need to view the properties, “the system cannot find the file specified.” is shown five times. attempts to examine the property. .
The problem persists. problems still exist.
What is the next step? what do you do next?
reference: https://stackoom.com/question/1OH70/ how to solve the specified service has been marked for deletion – error
There may be several causes which lead to the service being stuck in “marked for deletion”.
SysInternals’ Process Explorer is opened.SysInternals’ Process Explorer. Closing it should lead to automatic removal of the service. Closing it will cause the service to be automatically deleted.
Task Manager is the opened. Task Manager has been opened.
Microsoft Management Console (MMC) is opened.Microsoft Management Console (MMC) has opened. To ensure all instances are closed, run taskkill /F /IM mmc.exe.exe .exe To ensure that all instances are closed, run taskkill /F /IM mmc.exe.
Services console is opened. This is the same as the previous point, since the Services console is hosted by mmc. This is the same as last, because the Services console is hosted by MMC.
Event Viewer is the opened. Event Viewer has been opened. Again, this is the same as the third point. .
The key HKEY_LOCAL_MACHINE\\ \Services\\{service name} exists. key HKEY_LOCAL_MACHINE\\ \CurrentControlSet\\ \\{service name} exists.
Someone else is logged into the server and has one of the previously mentioned applications.
An instance of Visual Studio used to debug the service is open. Visual Studio instance used to debug the service is open.
This can also be caused by leaving the Services console open. may also be caused by opening the service console. Windows won’t actually delete the service until it is closed. Windows does not actually delete the service until it is closed.
In my case, it was caused by unhandled exception while creating eventLog source. is caused by an exception that was not handled when the eventLog source was created. Use try catch to pin point the cause. Use try catch to identify the cause.
finds another thing to check – look it up in the task manager – if other users are connected to this box, even if they are “disconnected,” you must actually log them out to eventually delete the service.
open task manager > select services tab > select the service > right click and select “go to process” > Right click on the process and select End process open task manager > Select the service TAB & GT; Select service & GT; Right-click and select Go to Process & GT; Right-click the process, and select end process
Service should be gone after that after that Service should be gone

uninstall the app with the same package name and then install

but looking at this discussion on Stack Overflow, it doesn’t seem to say what the problem is because of

reason involves the jarsigner, don’t know why the company network temporarily can’t open it, see you later add study reasons.

search data found that it was related to the android system version of the mobile phone, my mobile phone is android 9.0, and I have some requirements on the management rights of the file
first step, specify a FileProvider. Declare an entry
in the androidmanifest.xml
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.myapp">
<application
...>
<provider
android:name=".app.MyFileProvider"
android:authorities="${applicationId}.provider"
android:exported="false"
android:grantUriPermissions="true">
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="@xml/provider_paths"
tools:replace="android:resource" />
</provider>
...
</application>
</manifest>
second step, need in project res-> Add: provider_paths.xml
external-path specifies the directory you want to share. The name can be arbitrary but try to avoid the same as above. Path specifies the desired directory
then add the following at the bottom:
<?xml version="1.0" encoding="utf-8"?>
<paths>
.........
<external-path
name="picture_selector"
path="PictureSelector/" />
</paths>
there are many solutions for this kind of error on the Internet,
, I will only say that I encountered the situation, has been bothering me for a long time, all kinds of methods have not been solved, finally by replacing HTTPS request with HTTP request will not appear this error.
