Playing with databases...

Is there any way to add one database (dBaseIV) to another so that there isn't any dublicates in data?
Here's example:
I've got one database where is datas from 1/1/1998 to 15/6/1998 and another where is datas from 1/6/1998 to 30/6/1998. I wanna kind of update this first database so that there is all datas from 1/1/1998 to 30/6/1998.

Could there be any SQL-clause to do this? If there is could you give me example?

Thanks for advance.

When I've had to do this, I've used the following method:

Dim srcRs As Recordset
Dim destRs As Recordset
Dim SQL As String

SQL = "SELECT * FROM MyTable WHERE MyField = '" & srcRs("MyField") & "'"

set destRs = db.OpenRecordset(SQL)
destRs.MoveLast
destRs.MoveFirst
If destRs.Recordcount <> 0
    'Move record from one table to the other because it doesn't exist
End If
destRs.Close
