Severe Issues - Sqlsrv driver does not work - Dashboard crashes

In the description you say: "Supports Multiple DB Types: MySQL, MySQLi, PostgreSQL, SQLite, Oracle etc."
How can i know what „etc.“ means? Can i get a refund, it is of no use for me like that.

Still waiting for an answer, pls reply

Just bought vdata as I was uncertain if mssql is supported.
In the description you say: "Supports Multiple DB Types: MySQL, MySQLi, PostgreSQL, SQLite, Oracle etc."
What is etc.?

1st: Entering a database with driver "sqlsrv" works in configuration. But trying to create a profile I get:

Microsoft][ODBC Driver 17 for SQL Server][SQL Server]Procedure  'show' not found.

[$conn = new PDO("sqlsrv:Server=$hostname;Database=$dbname", $username, $password);
        $conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);

error on line 20 at column 61: EntityRef: expecting ';'
