When having any issue fetching data from Data Source to Qlik Products(QlikView or Qlik Sense) via ODBC DSN, it is crucial to determine whether it is general or Qlik specific.
In order to investigate, the best way is to establish connection and fetch data from a 3rd party tool. Chances are:
If a 3rd party tool cannot fetch data either, or gets the same result as Qlik Products, then the issue falls outside of Qlik Products.
If a 3rd party tool can fetch data but Qlik Products cannot, or gets different result, then the issue falls inside Qlik Products.
