when i use the same sql statement, the command line is successfully inserted, but the http interface reports an error.
Is this a bug? i want to know how to fix this.
what the error is ?
it is very possible that you forgot to bring taosadapter process up .
that is the most common reason for TDengine database

What is the cause of this error when data is written into the TDengine database?
TDengine ERROR (80000014): Database not ready
The error message "TDengine ERROR (80000014): Database not ready" indicates that the TDengine database is not yet ready to accept incoming data. This error typically occurs when the database is starting up, initializing data structures, or recovering from a crash.
There could be several reasons for the database not being ready:
1.The TDengine server is still starting up: In this case, the error message should go away once the server has fully started and is ready to accept incoming data.
2.The TDengine server is undergoing maintenance or is in the process of a software upgrade: In this case, you may need to wait until the maintenance or upgrade has completed before trying to write data to the database again.
3.The TDengine server has encountered an error: In this case, you may need to investigate the error log or reach out to the TDengine support team for assistance.
4.The TDengine client is not configured correctly: In this case, you may need to check the client configuration and ensure that the correct hostname, port number, and database name are specified.
If the error persists, it is recommended to check the TDengine log files and consult the TDengine documentation or support team for further guidance.
I'm trying to use SSIS to load some data from Oracle database to MSSQL database.
I created the project and used the ADO.Net source and was able to create a connection to Oracle and run queries and view results.
However when I actually run the package I get the following error:
Error: 0xC0208449 at Data Flow Task, ADO NET Source 2: ADO NET Source has failed to acquire the connection {EECB236A-59EA-475E-AE82-52871D15952D} with the following error message: "Could not create a managed connection manager.".
It seems similar to the issue here
And I did find that I have two oracle clients version installed "11.1" and "12.2".
One is used by PL/SQL and the other by other entity framework project.
If this is the issue I just wanted a way to tell the SSIS to pick-up the correct one.
I tried adding Entry in machine.config for "oracle.manageddataaccess.client" section with the desired version.
I also tried using other types of data sources but couldn't even create a successful connection
I tried changing the Run64bitRuntime property in the project to False
Note: I don't have SSIS installed on my machine.
Eventually, I just had to remove the entries related to 11.1 in path variable then restarted my machine.
Also I switched to "dotConnectForOracle" for connection and now it seems to be working fine.
I'm expecting issues related to other applications that might still be using the 11.1 version, but that will be a problem for another day.
Always make sure to write the user (oracle schema) in uppercase and some special characters [in my case it was $] in the password needs escape character even if you're using the wizard not the cmd
I still don't understand the whole issue but I hope this helps someone some day.
I tried creating a mysql stored procedures, it was okay. I tried to create a function of mysql stored function but I am having this error.
Did some research but was afraid to try because there were a lot of solution. I don't know which one is real.
I tried also checking the privilege in phpmyadmin side. Not working.
I also tried updating log_bin_trust_function_creators to 1 and caused an error. below is the image attached with error.
This is the error when I tried creating a function in aws server via phpmyadmin:
As the error message indicates, you need to set log_bin_trust_function_creators to 1 in the RDS parameter group.
It is not "less safe" in a meaningful sense in RDS.

I have a problem with the creation of a new database.
After that I started MonetDB Server, I insert this command:
mserver5 --dbpath="C:\database1"
But the server give me this error:
!SintaxException:parseError:mserver5 --dbpath="C:\database1"
!SintaxException:parseError: ^';' expected
What should i do to resolve this problem?
Thanks
What MonetDB version are you using on what platform?
Presumably Windows and this error message is indicative of a broken installation, potentially caused by moving files/folders around directly on your machine, such that the expected location for server initialisation files can not be found.
We have some scripts that we run as part of our unit tests.
This worked fine until today.
We have tried running scripts with both windows and sql authentication.
We have no problems logging in using sql manager
Anybody have any ideas why we get the following error:
Shared Memory Provider: No process is on the other end of the pipe.
Sqlcmd: Error: Microsoft SQL Native Client : Communication link failure.
Thanks

EDIT
Thanks for the replys. The actual appears to be a password problem, which used up all the connections. The process was not listening because there were no available connections.
Look in SQL Server Configuration Manager and make sure the protocols you are using to connect to it are setup correctly. I suggest you enable "Shared Memory" and "TCP/IP".
Ask around, try and determine what was changed on your environment--by who, and how--that caused a working process to stop working. If succesful, you will (a) have a strong lead on discovering the details of what's going wrong, and (b) be in a position to ensure it doesn't recur. (Just solving the tech side might not prevent it from happening again...)
