    Unanswered: data import

    I have two databases identical in structure but with different data (staging database and a production database). There is a bunch of data in the staging database that needs to be moved to the production database. The data is in two tables and a foreign key link exists between them. The ID's in the tables of both databases started with '1' and started incrementing, so if I import all the data into production, there will be duplicate ID's.

    Is there an easy way to combine these tables? I'm not really a dba, but familiar enough with sql from an admin standpoint.

    Thanks for any advice

    This is why you should use GUIDs instead of Identity values.

    One way around this problem is to add a column to your production tables to store the original ID. Then you can recreate the record relationships after new Identity values are assigned.
    If it's not practically useful, then it's practically useless.
