I\'m using the following:
DRIVER={Vertica ODBC Driver 4.1}; SERVER=lnxtabdb01.xxxx.com; PORT=5433; DATABASE=vertica; USER=dbadmin; PASSWORD=vertica; OPTION=3
I too have not seen any way to use ODBC without a DSN. Here's my DSN settings for my linux workstation.
[VerticaDSN] Description = VerticaDSN ODBC driver Driver = /opt/vertica/lib64//libverticaodbc_unixodbc.so Database = Retail Servername = localhost UserName = vertica Password = Port = 5433
