[Søren Merser]

hi, use paste:
# a string/number/date
pn <-  '39R5238';
sql <- paste("select u.unitid from test where part =",  pn)
                                                                        ^^

# an array of strings/numbers/dates
pn=c(1,2,3,4)
sql <- paste("select u.unitid from test where part in (",  paste(pn, 
collapse=','), ")")
                                                                        ^^
