Set Near - Question
Hello,
I have a table "student" that tracks which day a particular student takes a lesson, what time, which room, and with which instructor. In other words the pertinent fields are stu_day, stu_room, stu_bgntime and stu_endtime.
I have an index that is called stu_day which is str(stu_day)+stu_room+str(stu_bgntime).
Lets say I have a student scheduled for day 1, room 1 , and from 1:00pm to 2:00pm.
My problem is ... that if I set order to stu_day and do a seek on day 1, room 1 and bgntime of 1:30 I would like this particular student to be selected, However the index is set on stu_bgntime so this student will not be selected. If I "Set Near on" it will find the next record. Is there a way to do a find <= on an index in VFP. Or is the best way to do this to "Set Near On" and then if !found() do a seek -1 and then do some checking to make sure the time is "Between" stu_bgntime and stu_endtime and the day and room are correct?
Sorry if this is a stupid question.
