HP Vertica: non of INTERVAL values are supported #337

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?

    Connect to Vertica db and query for example: "SELECT INTERVAL '1 DAY'"

What is the expected output? What do you see instead?

    I dont know, I think one of ['DateFromTicks', 'TimeFromTicks', 'TimestampFromTicks'] types. And I get exception: 
    pyodbc.Error: ('ODBC data type 1xx not supported. Cannot read column XXXX', 'HY000')

What version of the product are you using? On what operating system?

    OS: Ubuntu 12.10
    Python: Python 2.7.3
    pyodbc: 3.x

>>> import pyodbc
>>> pyodbc.version
'3.0.6'
>>> con = pyodbc.connect(dsn='Vertica')
>>> con.execute("SELECT INTERVAL '1 DAY'")
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
pyodbc.Error: ('ODBC data type 110 is not supported.  Cannot read column 
?column?.', 'HY000')

I have this same issue with NetezzaSQL database. Data type 110 is not supported.

I think that INTERVAl data type is not on road map so far.
As workaround - covert interval to int(seconds).

Use vertica-pyodbc.
much better connector.
