Teradata Python Module

Tools covers the tools and utilities you use to work with Teradata and its supporting ecosystem. You'll find information on everything from the Teradata Eclipse plug-in to load/extract tools.

Re: Teradata Python Module


I have found that for linux, you will need to have a version of pip for each version of python (in my case it was 2.7).

To have RHEL use 2.7 by default instead of 2.6:

Create /etc/profile.d/enablepython27.sh

In the file:


source scl_source enable python27

From <https://access.redhat.com/solutions/527703>

Open up permissions to allow it to apply to all users


To install an alternate version of pip:

curl -O https://bootstrap.pypa.io/get-pip.py

python get-pip.py

Then you can install the teradata module:

pip2.7 install teradata


Re: Teradata Python Module


sorry, i neglected to mention that in order to get the above to work, I needed to add the software collection repo:

To install python 2.7:

Add the software collection repo:

wget -qO- http://people.redhat.com/bkabrda/scl_python27.repo >> /etc/yum.repos.d/scl.repo

For some reason I would sometimes need to clean out the repo list after this to get installs to work:

mkdir /etc/yum.repos.d/repo.disabled

yum clean all

yum install python27


Re: Teradata Python Module

Thanks for the response. I actually have my default python set to python3.4. My only issue is that the Teradata module is not taking the python3.4 version.

[root@ttudev ]# python

Python 3.4.3 (default, Sep 22 2015, 12:23:35)

[GCC 4.4.7 20120313 (Red Hat 4.4.7-16)] on linux

Type "help", "copyright", "credits" or "license" for more information.


I am getting the below error when I try to install the alternate version of PIP.

[root@ttudev]# curl -O https://bootstrap.pypa.io/get-pip.py

Not sure why it says zlib not available. I see the rpm is already there.

[root@ttudev]# rpm -qa |grep zlib



Re: Teradata Python Module

yea thats likely because pip2.6 is running the install. Can you check to see if pip3.4 exists already?


Re: Teradata Python Module

pip3.4 does not seem to be there. This is what I see in /usr/bin

[root@ttudev bin]# cd ../../bin

[root@ttudev bin]# ls -ltr pip*

-rwxr-xr-x 1 root root 204 Sep 23 09:05 pip

-rwxr-xr-x 1 root root 204 Sep 23 09:05 pip2.6

-rwxr-xr-x 1 root root 204 Sep 23 09:05 pip2

I think the issue will get resolved , if I install pip3.4 successfully.


Re: Teradata Python Module

Any help here please?

Re: Teradata Python Module

Python3.4 is suppose to include setuptools and pip so not sure why those modules cannot be found.  Can you try executing the following command?

python3.4 -m ensurepip

Re: Teradata Python Module

@cw171001 -  I created an SP with the same signature that returns output parameters with the maximum number of characters but I am unable to reproduce the error you are hitting.    Could you try upgrading the Teradata Python Module if you're not already using the latest version?  Is the same environment (e.g. Database and ODBC version), the same session attributes (e.g. user, transaction mode, charset, etc.), and the same SP arguments being used when comparing SQL Assistant vs. Python?
