Disable table name quotes for querying through Oracle DBLINK

TL/DR: Is there a way to disable adding double quotes for table names like MY_TABLE@MY_LINK_NAME when using System.Data.Linq.Mapping attributes?

Hello,

I have a large application migrated from BLToolkit to Linq2db. Everything works great so far except for external tables accessed via Oracle DBLINK. Tables accessed via DBLINK are named like this: MY_TABLE@MY_LINK_NAME:

SELECT ID, NAME FROM MY_TABLE@MY_LINK_NAME

Note that it looks like a table name with special symbols in it, but in fact it isn’t. Database entities are annotated using System.Data.Linq.Mapping attributes:

[Table(Name = "MY_TABLE@MY_LINK_NAME")]
public class MyTable
{
     [Column(Name = "ID")]
     public long ID { get; set; }
}

BLToolkit used to generate table name as is:

SELECT ID, NAME 
FROM MY_TABLE@MY_LINK_NAME

But Linq2db detects a ‘@’ symbol and quotes the table name:

SELECT ID, NAME 
FROM "MY_TABLE@MY_LINK_NAME"

Which is an error because such table doesn’t exist in the database. I don’t seem to be able to find a workaround so far. I found a compatibility option OracleTools.DontEscapeLowercaseIdentifiers that affects table names with lowercase letters, but there is no such an option for the DBLINK @ character.

Environment details

linq2db version: 3.0.0.0 Database Server: Oracle Database Provider: OracleManaged Operating system: Windows .NET Framework: 4.6.1

Technically, you can also replace SystemDataLinqAttributeReader with own implementation, which split table name into Name/Server parts

Thanks for the ServerName extension method workaround:

var result = db.GetTable<Sector>().ServerName("STATS")
   .ToList();
