Using a non-standard port using Microsoft SQL Server ODBC Driver
Connection string
This Microsoft SQL Server ODBC Driver connection string can be used for connections to SQL Server 2000 and SQL Server 7.0.
If your SQL Server listens on a non-default port you can specify that using the servername,xxxx syntax (note the comma, it's not a colon).
Driver={SQL Server};Server=myServerName,myPortNumber;Database=myDataBase;
Uid=myUsername;Pwd=myPassword;
The default SQL Server port is 1433 and there is no need to specify that in the connection string.
