Re: compare 2 recordsets

What would be the best (fastest) way to do this:
I have 2 ADO recordsets say A and B.
They both have a common field, say ID
Now I need to delete all the records in recordset A where
the value in the field ID is not found in the field in recordset B.
These are values of the datatype Long.
The ID field will be sorted ascending in both recordsets.

Now, I could do this with a double loop, but that could be a bit slow
and I wonder if this could be done better with a filter or find.

Why are you using recordsets for this? Are the recordsets from different
databases?
If not, this is a job for SQL.
If so, there's no alternative to looping through one of them, but you can
use Filter to get the corresponding records in the other recordset.
