hi Jennie, thanks for spending time on this! won't LIMIT only give one record? i need one record per event.. so i think the "insert into" command would need to be repeatedly called until every single event got stored (which would take forever)? sorry if i'm missing something

Maybe I’m thinking in a too simple way, but if you store the intermediate results in a table, you can use LIMIT 1:
CREATE TABLE t1 (svcmon int); -- assume svcmon is an INT insert into t1 SELECT svcmon FROM person_table AS z WHERE a.yr = z.yr AND a.person_id = z.person_id ORDER BY abs( z.svcmon - a.svcmon ) LIMIT 1;
Using TEMP TABLE might give you a bit speed up, but then you need to put them in one transaction.
