Change Existing Data for Development

B

BMC

Hi

I have 2 # production databases that are populated with personal data.

I want to copy the databases for third party development purposes have ever
I need to change existing data i.e. Personal names to say "John/Jane Doe"

Is there a way of doing this quickly, I have about 25,000 records per
database.

Regards

Run a series of update queries to change the data. If you are changing
to a constant value then you might use something like the following.

UPDATE YourTable
SET [LastName] = "Doe"
, [FirstName] = "John"
WHERE Gender = "Male"

UPDATE YourTable
SET [LastName] = "Doe"
, [FirstName] = "Jane"
WHERE Gender = "Female"

UPDATE YourTable
SET [LastName] = "Doe"
, [FirstName] = "Marti"
WHERE Gender Is Null

If you had an SSN you might use a VBA function to scramble the numbers
or just replace all 1's with 2's, all 3's with 4's etc.

Your question is not clear. Is your database split? If not, it should be.
Then to change data, all you would need to do would be link to a different
back end.

If it is not split, it is a bit of work. You would have to delete all the
tables in your database and import them from the other database, then
reestablish your relationships.
