I'm using Django in VSCode and want to connect to the MySQL database, I've created the database in MySQL. When changing the database configuration from mysqlite to MySQL in settings.py, and do the migrate, the error pops up (in the picture below). Basically it says malloc error and asks me to set a breakpoint in malloc_error_break to debug.
I have no idea of what's going on here. Anyone knows how to fix this error? The error message disappears once I changed the settings back to sqlite, it only happens when using MySQL.

Thanks a lot for taking the time to help us improve MySQL Workbench!

I'm currently using MySQL Query browser to view the database of my website. Then I encountered this error
error 1049 unknown database 'testajax'
I already dropped this database after using it to test an ajax function. Then my website did not work liked it used to before. Specifically, I cannot INSERT but I can fetch some of the data from my database. I'm a beginner in MySQL, I looked at the tools tab, MySQL Administrator > Server Connections and then I saw this: (Please click to see the image) I found that my database (crb). Is on sleep command. Is this the reason that's why I cannot use my database? If yes, how can I set my database to active to use it again?
I am running Visual Studio 2010, and attempting to update my Entity Framework project using the Update Wizard. When I attempt to add a single table from the MySql database, the add tab will show the table that I am attempting to add, however when I click finish, I get the following error message.
Unable to generate the model because of the following exception: 'An error occurred while executing the command definition. See the inner exception for details.
Fatal error encountered during command execution.
Fatal error encountered attempting to read the resultset.
Reading from the stream has failed.
Attempted to read past the end of the stream.
I get the same error message if attempt to create the Entity Framework from scratch. In addition, Server Explorer shows that the connection is successful when I test it.
I have also contacted Host Gator who is hosting the database and they where not able to see any issues on their side.
The problem ended up being that our shared server, was not able to handle the Update Request from the Entity Connector Framework and was timing out. Once we moved our database over to a different server we no longer had an issue.
I'm attempting to use the 'Read Database' operator in RapidMiner 5 to read an 'ExampleSet' from a Mysql database. I seem to establish a working connection with my db as I notice the Manage Database Connections window displays a 'Connection ok' message when prompted.
However when I attempt to run the 'Read Database' process I receive the following error
"Process failed:
Failed to lookup .javax.naming.NoInitialContextException:
Need to specify class name in environment or system property, or as an applet parameter,
or in an application resouce file:
java.naming.factory.initial"
I don't know how to interpret this error. Do I need to set an environmental variable?
Seems that my problem can be remedied by upgrading mysql. I had been version 5.0, but after upgrading to version 5.5, my problem went away. Details remain unknown.
Long time lurker, first time poster; hoping anyone can help me out.
Im using MySQL Workbench 5.2.41 to migrate a database from SQL Server to MySQL 5.0.8
The entire process goes smoothly: both SQL and MySQL connection Tests are good, the skemea and table create as expected, everything checks out until the 'Bulk Data Transfer' step. At that point I receive this error:
...
Migrating data...
wbcopytables.exe --odbc-source=DSN=SQL Server 11;DATABASE=;UID=sa --target=root#127.0.0.1:3306 --progress --passwords-from-stdin --thread-count=1 --table [GSAClosers_v2] [dbo].[AccountBase] `dbo` `AccountBase`
`dbo`.`AccountBase`:Copying 84 columns of 169530 rows from table [GSAClosers_v2].[dbo].[AccountBase]
ERROR: `dbo`.`AccountBase`:SQLGetData: HY009:10:[Microsoft][ODBC Driver Manager] Invalid argument value `dbo`.`AccountBase`:
Finished copying 0 rows in 0m00s

For connectors I'm using Microsoft SQL Server / ODBC Data Source / DSN: SQL Server and for MySQL the IP and port(3306).
SQL Server 2012 Management Studio connects and all operations work as expected.
O, side not: both are on the same localhost machine.
If anyone can shed some light on this I would be forever indebted. Thanks in advance
From here:
[Microsoft][ODBC Driver Manager] Invalid argument value.
Regarding to the error message and code you provided, which seems is
database is invalid or cannot be accessed. That means either the
database does not exist or the user does not have permission to access
the database.
It turns out you need specify the instance after the server name, so
in the server name in the dialog box for creating the ODBC Data
Source, you must enter it as either: MyServer\SQLEXPRESS or
.\SQLEXPRESS
I think you may have a problem connecting to your database from wbcopytables.exe. Keep in mind that this is a separate tool so the fact that you can connect from the rest of the Migration Wizard doesn't imply that you will connect in wbcopytables.exe.
The thing that worries me the most is that your DSN has whitespace characters. This might be interpreted by the Windows terminal as independent command line parameters. One thing you can do is to edit your DSN name removing the whitespaces and try again.
You may also want to connect without a DSN by putting all your connection parameters explicitely as explained in my blog post: How-To: Guide to Database Migration from Microsoft SQL Server using MySQL Workbench.
And, by the way, since MySQL Workbench 5.2.42 is out you should go and get it. The Migration Wizard is pretty new so important bug fixes are likely launched in each recent Workbench release.
In either case I think you should file a bug with your issues with a detailed explanation about how to reproduce it, possible solutions, etc.
Hope this helps.
Ok, got it figured out: un-install java. install java 1.6, use MySQL Migration Tool. change all data types to varchar, ints and bits. run migrations....eat data.
