Update unique records only help

I am trying to read in text data from a field in one table and then append it to data in a second table, but only if its unique. Any thoughts on how best to do that?

Ex Table A has:
bug #12345
bug #67890

And Table B has:
The following bugs are
bug #12345

Now I want to select the data from A and add the unique information (bug #67890) to B.
