    I have a large client database of 53000, and currently i have the need to split these into batches of 400 and export to an excel sheet or another table in the database.

    Please help.

    One approach you could take is to add a yes/no field to your client table that records whether that client has been exported.

    Then create a select query (let's call it qryExportList) that goes something like

    Code:
    Select Top 400 ClientID, ClientFName, ClientLName, (add in all the other fields you want here, seperated by commas)
    From tblClients
    Where [Client_Exported]=0
    Order By [ClientID];
    Then, use the docmd.transferspreadsheet vba command to export the results of that query to a spreadsheet. You may wish to prompt the user to provide a filename to be used for the export. Checkout access help on how to use this vba function, or do a google search.

    Then immediately followup that export event by running an update query that goes something this:

    Code:
    Update [tblClients] 
    INNER JOIN [qryExportList] ON [tblClients].[ClientID] = [qryExportList].[ClientID]
    SET [tblClients].[Client_Exported] = -1;
    Then, after you have run the update query, repeat the process and you should get the next 400 clients.
