I am getting error when updating the edmx
Unable to generate the model because of the following exception: 'An error occurred while executing the command definition. See the inner exception for details.
Illegal mix of collations (utf8_bin,NONE) and (utf8_bin,NONE) for operation '='
How do I solve this problem ? I have tried so many things. It would be great help if anyone help me to solve out this error.
Thanks

When one is playing with the tools offered by Microsoft and Oracle simultaneously, the two don't always sit right with each other. Quite recently I had to integrate MySQL with Visual Studio using Entity Framwork and its was quite a mess.
As far as my research on the internet goes, most of the people trying to achieve the said target encountered the following problems or errors and I was unlucky enough to encounter all of them:
Authentication Probelm : "Authentication method 'caching_sha2_password' not supported by any of the available plugins"
Entity Framework doesn't generate the Entity Data Model:
Choose 'EF Designer from database'
Choose the connection from the drop down (localhost) that already tested successfully connecting to MySQL databse
The "Save connection settings in webc.config as" option is checked
I click 'Next' AND the window disappeared and I get back to the code window
No .edmx file is generated
Edmx file is generated but there is no Entity Data Model in it and the output windows shows one of the following 2 exceptions: "Illegal mix of collations (utf8_bin,NONE) and (utf8_bin,NONE) for operation '='" OR "Illegal mix of collations for operations 'Union'"
Entity Framework version is not compatible with the one required by MySQL.
MySQL Integration with Visual Studio Guidelines
Requirements:
Visual Studio 2012 or above
Dot Net Framework 4.5 or above
MySQL Installer Community 5.7.23.0
MySQL Workbench Community 6.3.9-winx64
MySQL Connector\Net 6.8.8
MySQL For Visual Studio 1.2.7
Entity Framework 5
Installation Steps:
Install the target version of Visual Studio first i.e. VS-2012 or above. The order of installation does matter.
Download the above mentioned MySQL’s components separately.
Install the MySQL Installer Community 5.7.23.0 and let it install all the default components. Select "Sha256_Password" authentication instead of "Caching_Sha2_password".
After its finished installing, close the MySQL installer and reopen it from the start menu.
Click on the “remove” option.
Uninstall MySQL for Visual Studio, MySQL Connector\Net and MySQL Workbench.
Run the setups for MySQL Connector\Net 6.8.8, MySQL for Visual Studio 1.2.7, & MySQL Workbench Community 6.3.9-winx64 individually and install them manually one by one.
Now the MySQL environment is all set to be integrated with Visual Studio and Entity Framework.
Note:
The versions of the MySQL Components plus the environment of Visual Studio and its frameworks should exactly match with the ones mentioned above otherwise the things will not be cohesive and the developer will end up dealing with some unwanted and rigid problems.
I'm trying to connect to Oracle database through the Electron app I'm building. What options do I have?
Use node-oracledb. Electron has some ABI compatibility issues so review what other node-oracledb users are doing before you start.
I am having an application that is running on IIS with Enabled 32 bit Application.
In a remote server(connection available in local machine),i have installed Pervasive SQL.
I have installed Pervasive SQL Driver in local machine and trying to connect the database "TestApplication" in Pervasive SQL.
For that I have created System DSN "DSNTEST", and tried with Windows Application.Its working fine.
But i couldnt connect to the database from Web Site.
An error occured "Error: ERROR [IM014] [Microsoft][ODBC Driver Manager] The specified DSN contains an architecture mismatch between the Driver and Application".
Can anyone please help me to resolve this?
Thanks in advance.
It sounds like the ASP.NET application is trying to run as a 64 bit application. Because you're using PSQL v11, you can install the 64 bit ODBC driver which is part of the PSQL v11 64 bit client install (at http://www.pervasive.com/database/Home/Products/PSQLv11.aspx).
The other option is to make sure that the ASP.NET project is built with a target of x86 rather than x64 or AnyCPU.
i am new to the oracle. ,My project is .net web application which is connected to the oracle database(oracle 11g) when i run my solution in local environment, i get the error in the below line saying that "Could not create connection from Driver".
return factory.ConnectionProvider.GetConnection();
but this project is working fine in windows XP and I am using windows 7 with oracle 11g installed in my system where i am facing the problem.please can any one give solution.
I understand from the team that this project is designed with oracle 9.2 in mind. how do i make it work in oracle 11g which i have it currently.
I would advise you to use Oracle's Managed Data Provider for .NET. All your problems with local Oracle installations will go away immediately. Since it's a 100% managed driver, you won't need to install Oracle's client on your machine before connecting to it with .NET programs.
Has anyone here successfully used the Microsoft Sync Framework (see the docs) to sync between MS SQL Server 2012 and PostgreSQL 9.x?
Can it work when the postgreSQL server resides in a Linux environment?
Thanks!
there is no PostgreSQL sync provider out of the box, so you will have to write your own.
have a look a the sample Oracle sync provider here: Database Sync: Oracle and SQL Compact 2-Tier
doesnt matter if your PostgreSQL is in Linux since you're just connecting to it. you dont have to install anything for the sync on the Linux side.
