To use the ODBC driver with named pipes on Windows I looked into the documentation and didn't get it to work.
https://mariadb.com/kb/en/about-mariadb-connector-odbc/

There are three sentences about named pipes:

So my connection string should be (ADO):

Driver={MariaDB ODBC 3.1 Driver};NAMEDPIPE=1;SERVER=MyPipeName;USER=user;PASSWORD=password

But this doesn't work. Instead you always get this error:

[ma-3.1.17]Can't open named pipe to host: MyPipeName  pipe: MySQL (53)

The working connection string uses SOCKET instead of SERVER on Windows:

Driver={MariaDB ODBC 3.1 Driver};NAMEDPIPE=1;SOCKET=MyPipeName;USER=user;PASSWORD=password

This works fine. But the documentation explicitely says that "Server is treated as a named pipe name". Also the documentation for "Socket" says "It has effect on Linux only."
Both sentences are wrong.

It would be nice if you could fix the documentation.
