Hi @ramuboggarapu,

which jdbc driver are you using?
And do you use any connection parameter?
Else you can set the character set to UTF, which should solve these issues :slight_smile:

We are using DB Connector to connect teradata DB and default driver we are using Teradata[ID: Teradata]

Where can I set the character set to UTF while using DB reader C
Thanks for the help

Hi @ramuboggarapu,
If I remeber correctly you should just add the CHARSET parameter with your needed character set:

If that does not fix the selection - then you should verify if the table definition in Teradata is correct and supports the german characters correctly.

Teradata JDBC Parameters can be found here:

Thanks it works for me but teradata driver also has to be update in knime

Hi @ramuboggarapu,

great that it works now.
However just to clarify - as far as I know there is no default “Teradata[ID: Teradata]” driver in KNIME…
This driver was most likely setup on your end
(if not by you then most likely directly by your IT)

->so nothing the KNIME colleagues can do (besides providing this driver by default - which would be great :slight_smile:)
