Hi all,
I have 2 files containing Id numbers and surnames (these files
essentially contain the same data) I want to select distinct() and
join on id number to return a recordset containing every individual
listed in both the files HOWEVER, in some cases an incomplete ID
number has been collected into one of the 2 files -is there a way to
join on partial matches not just identical records in the same way as
you can select where LIKE '%blah, blah%'??
Is hash joining an option i should investigate?

TIA
Mark
