I tried to call my SP using callproc method and by passing my inputs and output parameters.
The procedure ran successfully but the output variable is empty (u'').

So, I went to the discussion on official page and found a simple code snippet and even that didn't work out.

I tried following code:-

`for result in session.execute(
"""REPLACE PROCEDURE test.testProcedure1
(IN p1 INTEGER, OUT p2 INTEGER)
BEGIN
SET p2 = p1;
END;"""):
print(result)

result = session.callproc(
"test.testProcedure1",
(12345, teradata.OutParam("p2", dataType="INTEGER")))
print(result.p2)
`
The result it printed for result.p2 was:-
NaN

The logs generated shows following line:-

Procedure Executed! Duration: 0.075 seconds, Procedure: test.testProcedure1, Params: (12345, OutParam(name=p2, size=-3))

Using:-

1. python (2.7.10) - teradata module version - 15.10.0.21
2. Teradata 16.10

Please help!
