    Large Table Update

    I have a table in database, with pk as internal no and in normalised form.

    Here user will import an excel with the information having internal no, my task is to match the internal no and update the required row with the data.

    How ever i can do it, by running set of queries, i want to know if there any more quicker side, where u can compare first the entries and not matching then update, yes it will be the case if blank also there.

    any help

    Linking to or importing the spreadsheet then running UPDATE or INSERT action queries is probably the fastest and easiest, assuming the spreadsheet structure allows linking/import. Otherwise, VBA can open the spreadsheet as an object in code and read each cell one at a time. Complicated code.
    How to attach file: To provide db: copy, remove confidential data, run compact & repair, zip w/Windows Compression.
