GO in SQL Statement

I am getting this exception when including the keyword "GO" into my MSQL script:

SQLServerException: Incorrect syntax near 'go'.

When I execute exactly the same statement in the SQL Server Management Studio I don't get any problem.

I read on the internet:
http://www.mischefamily.com/nathan/index.cfm/2008/7/3/Do-not-pass-GO

that in order to this to work, the delimiter "GO" must be defined.

So I tried:
jdbc.url: jdbc:sqlserver://localhost;UserName=username;password=password;databaseName=db;delimiter=go

But it is still not working.
How to make this work?

Using smartgwt 5.0p 27.01 and MSSQL 2014
