Hi,
I have the following tables in my python code.When i try to access the
adSuggester['trId'] it works but whereas when i try to use
queryToken['qId'] it throws me an keyerror.However this is strange because
this key exists in the definition of the table.Please help me to resolve
this issue.
Thanks
