DLL error on connecting to Latin1_General_BIN collation server

[MasterOdin]

When using tedious, I cannot connect to SQL Server using the Latin1_General_BIN collation created using the docker image that MS puts out. The server is created using the following command:

docker run --rm -d --name sqlserver -p 1433:1433 -e "ACCEPT_EULA=Y" -e "SA_PASSWORD=Password(12)" -e "MSSQL_COLLATION=Latin1_General_BIN" mcr.microsoft.com/mssql/server:2017-latest

When attempting to connect, I get the following error:

RequestError: Could not load the DLL (server internal), or one of the DLLs it references. Reason: 126(The specified module could not be found.).

}

with the following lines being emitted by sqlserver in its error log:

I used the example connection code from the Getting Started section with the following configuration object:

var config = {
  server: "localhost",
  options: {
    database: 'master',
    encrypt: false
  },
  authentication: {
    type: "default",
    options: {  
      userName: "sa",
      password: "Password(12)",
    }
  }
};

I can connect to and query the server just fine using the following clients:

• msnodesqlv8@2
• sqlcmd
• pymssql
• PHP PDO
• JDBC via DataGrip

I can reproduce this, even with the mcr.microsoft.com/mssql/server:2019-latest container. I'll try and see what those other libraries do differently.

@IanChokS can you reach out to the SQLServer on Linux folks and see if they have an idea what's going on here? 🙇‍♂️

@MasterOdin I was able to get a successful connection and query using: docker version: 20.10.0, build 7287ab3 mssql verision: mcr.microsoft.com/mssql/server:2017-latest node version: v12.16.1 tedious version: 9.2.1 docker run command:

docker run -e "ACCEPT_EULA=Y" -e "SA_PASSWORD=Password(12)" -p 1433:1433 -d mcr.microsoft.com/mssql/server:2017-latest

sql column collation: Latin1_General_BIN .

I'm not sure what's causing your issue, but you can try removing that docker image and re-downloading it. I'm guessing a few files were corrupted when pulling the images from docker.

[MasterOdin]

@IanChokS, I'm confused to what you're getting at there. Your docker run command removes the MSSQL_COLLATION environment variable and so the server is set-up to use the default of SQL_Latin1_General_CP1_CI_AS. Sure, I can individually cast individual databases, tables, or columns to Latin1_General_BIN and tedious will then work fine, but as soon as I want the server itself in Latin1_General_BIN, then tedious would break again, putting me back into my original issue.

To your last point on corrupted images, I've replicated this issue across two machines (and @arthurschreiber has replicated it as well on their end) that it would be that MSFT themselves are publishing bugged versions of SQLServer I guess, but then again, 5 other clients seem to have no issues with it, which I would think would be the case of a corrupted image.

[IanChokS]

Oh yes my bad 🤦‍♂️ I missed the -e "MSSQL_COLLATION=Latin1_General_BIN" in the run command, I'm seeing the issue as well

OK I've posted help on the Microsoft forum: https://docs.microsoft.com/en-us/answers/questions/221376/dll-error-on-connecting-to-latin1-general-bin-coll.html

I'll keep this discussion updated if I hear anything back from their side!
