Teradata - INT columns being returned as 0 instead of value on python27 #389

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago
What steps will reproduce the problem?
1. Connect to Teradata system
2. Query for INT columns
3.

What is the expected output? What do you see instead?
I expect to see values other than 0

What version of the product are you using? On what operating system?
pyodbc 3.0.7
python 2.7
CentOS release 5.11

Please provide any additional information below.

If in my query I CAST the INT as BIGINT it works.

Here is my sample code
import os
import pyodbc
pyodbc.pooling = False
os.environ['ODBCINI'] = '/etc/odbc.ini'

tdConn = pyodbc.connect(dsn='td_app', uid='dse', pwd='*******', autocommit=True)

cursor = tdConn.cursor()
#stmt = "sel top 10 seg_batch_sk, cast(size_cnt as bigint) from seg_batch_f 
where size_cnt > 0"
stmt = "sel top 10 seg_batch_sk, size_cnt from seg_batch_f where size_cnt > 0"

cursor.execute(stmt)

res = [row for row in cursor.fetchall()]

cursor.close()

print res

Here are the results
