Initial Code 
SELECT a.first, a.last, a.district, a.zip, b.zip, b.first, b.last, b.district 
FROM clerk_ballots a, lcv_members b
WHERE a.first LIKE b.first
AND b.last LIKE a.last
AND INSTR(b.district, a.district)
Initial URL 

                                

                                                            

                                    

                                        

                                        Initial Description
                                        

                                    

                                    
in this case, we wanted to match fields where the district field in table b contained things like "LAM2-OUTSIDETOWN" and we wanted to match that to fields in table a which only had "LAM2" in them. "INSTR" ("in string") is our friend:

find one string inside another string, comparing two columns
