Hello all,

 

I have a problem with my imported data from the database oracle sql developer:

Some data is now missing and is marked with a "?" How can I get the original data instead of the question mark?

    Hi tschulzeharl,

    we would need a bit more infomration in order to help you with that. Did you make sure to take care about formats when doing the import? If you are not sure on the format it is best to import content as text. You can then always change it something else if it is a number for example.

    Cheers, K.
