Testing the ODBC Connection

You can test the connection using iODBC or unixODBC. For more information, see:

Testing the Connection using iODBC

Verify the connection with Qubole using the iodbctest tool. The tool lists all DSNs if multiple DSNs configured. Check the driver version and enter the query to be processed on Qubole UI.

  1. Run the iodbctest command.
  2. In the command-line utility, type ? to see a list of available data sources.
  3. At the prompt, type a DSN from the list . For example, dsn=Qubole ODBC Driver DSN or dsn=Test (verify the version of driver after this step.) Verifying the Driver Version describes how to verify the driver version.
  4. At the SQL> prompt, enter the SHOW TABLES command.

Here is a sample illustration.

[ec2-user@aws-instance ~]$ iodbctest
iODBC Demonstration program
This program shows an interactive SQL processor
Driver Manager: 03.52.0709.0909

Enter ODBC connect string (? shows list): ?

DSN                              | Driver
------------------------------------------------------------
Qubole ODBC Driver DSN | QuboleODBC
Test                   | QuboleODBC
Enter ODBC connect string (? shows list): dsn=Test
Driver: 10.01.1031 (QuboleODBC)
SQL>[Show tables;]

Testing the Connection using unixODBC

Verify the connection with Qubole using the isql utility as mentioned in this command:

isql -v <DSN Name>

Here is a sample illustration.

[ec2-user@aws-instance ~]$ isql -v "Test"
+----------------------------------------+
| Connected!                                 |
| sql-statement                              |
| help [tablename]                           |
| quit                                       |
+----------------------------------------+
sql>[show tables;]

To verify the triggered query, navigate to the Analyze page on the Qubole UI.
