Invalid null value

  • Hello

    New to sql and learning the hard way.

    we had our 2005 sql go down so in order to get it up we have a 2000 sql server going.

    1. I restore a 2005 backup to the a 2005 develop version

    2. Restore an older 2000 backup onto the 2000 server. (we had moved the database from 2000 to 2005 back in august).

    3. deleted all data from the tables in the 2000 sql database.

    4. I exported all the data from table in the 2005 sql database to excel.

    5. I imported all the data to the empty tables in the sql 2000 database.

    Now when the program that the user use to reigister people for seminars they get the error 94 invalid use of naull value.

    I tried retoring the recent backup from the 2000 sql database that is sowing the errors in the 2005 sql develop and the error is still occuring.

    Any help would be great.

    The main cencern is getting it back to the 2005 without the error so when we stand up the new 2005 server.

    Thanks

  • Why didn't you just restore the 2005 backup on the 2005 server and continue from there? why take the data back to 2000 and then try to move forward to 2005 again?

  • the 2005 went down and i have a standalone development server on a laptop. no 2005 servwer are available. i am trying test to the 2005 dev to get ready when the new 2005 comes online

    thanks

  • Do you mean the 2005 installation is gone, or that it won't start up? (i.e. define 'gone down')

  • oh sorry the computer harddrive crash. nope of saving the original 2005 server install. i put it to a 2000 rather quickly so the users could have access it it.

  • After doing some more looking around and trying third file imports it seems that before i imported the records from the 2000 box the records in the 2005 box did not show anything in the empty fields when you open them in enterprize manager but after the import all of the empty fields now show NULL and the same error occurs in the 2005 sql indicating invalid null use error 94.

    Hope this helps
