    The same question from another post (for the forum users not speaking German):

    Hi Wolfsburg2011,

    I guess you tried using the operator "Write Access"!? Did you fill in any parameter fields? It seems you forgot to point to the database file. What this parameter expects is described in the operator help:

    database file: The mdb file containing the Access database which should be written to.

    The data in your database has to be stored somewhere. Access uses files with .mdb extension for storage, and this information is required. Where should the data go otherwise?

    Regards
    Matthias

    Hi Matthias,
    thanks a lot for your solution, I did it, but I wantet to Know, can I do it direkt without changing his format in csv!
    I want to know, can I write it in Access format. i.o. can I export it in Access format? I did it, but I got an error that says "Database could not be opened" even though I had given my csv file as DATABASE_ FILE. Thank you for your help ???

    Hi,
    you have to enter your DATABASE FILE there! The Access Database File, NOT the CSV file. The CSV file must be read, not written!

    Greetings,
