Unable to See rows using isql using ODBC connection for Vertica

I have created a connection and I am able to connect to the database using that. But when I select records from the table it is not coming up.

[dbadmin@Vertica sql]$ cat /etc/odbc.ini
[ODBC Data Sources]
VerticaDSN = "sfpdb database"
[VerticaDSN]
Description = SFP Database
Driver = /opt/vertica/lib64/libverticaodbc.so
Database = sfpdb
Servername = 16.181.233.133
UserName = dbadmin
Password = sfpdb
Port = 5433

[dbadmin@Vertica ~]$ isql -v VerticaDSN

Not sure whey I am unable to see all the three rows.
