How to deal with synthetic key when using IntervalMatch?
Thanks!
IntervalMatch (matchfield,keyfield1 [ , keyfield2, ... keyfield5 ] ) (loadstatement | selectstatement )
EventLog:
LOAD * Inline [
Time, Event, Comment, ProductionLine
00:00, 0, Start of shift 1, P1
01:00, 0, Start of shift 1, P2
01:18, 1, Line stop, P1
02:23, 2, Line restart 50%, P1
04:15, 3, Line speed 100%, P1
08:00, 4, Start of shift 2, P1
09:00, 4, Start of shift 2, P2
11:43, 5, End of production, P1
11:43, 5, End of production, P2
];
OrderLog:
LOAD * INLINE [
Start, End, Order, ProductionLine
01:00, 03:35, A, P1
02:30, 07:58, B, P1
03:04, 10:27, C, P1
07:23, 11:43, D, P2
];
//Link the field Time to the time intervals defined by the fields Start and End and match the values
// to the key ProductionLine.
Inner Join
IntervalMatch ( Time, ProductionLine )
LOAD Start, End, ProductionLine
Resident OrderLog;
