[resolved] WRONG OUTPUT IN COMPARE DATE

[Anonymous]

Dear All,
I am working on a job and i don't understand my out data because after many tests everything look good.
I have an input file with a date column and objective is to classify all rows by month
Example:
Input file with date MM/dd/yyyy
MLarronde;10/05/2015;Parrot;Parrot EPM & COMP;Billable;ACCEPTED
MLarronde;10/06/2015;Parrot;Parrot EPM & COMP;Billable;ACCEPTED
MLarronde;10/31/2015;Parrot;Parrot EPM & COMP;Billable;ACCEPTED
MLarronde;10/01/2015;Parrot;Parrot EPM & COMP;Billable;ACCEPTED
svautrot;09/15/2015;Bureau Veritas;Bureau Veritas - LMS ILT;Billable;ACCEPTED
svautrot;09/16/2015;WHO;Testing support;Billable;ACCEPTED
svautrot;09/16/2015;Bureau Veritas;Bureau Veritas - LMS ILT;Billable;ACCEPTED
svautrot;09/01/2015;Bureau Veritas;Bureau Veritas - LMS ILT;Billable;ACCEPTED

With these inputs i get this output
Output file for previous month (October)
MLarronde;10/05/2015;Parrot;Parrot EPM & COMP;Billable;ACCEPTED
MLarronde;10/06/2015;Parrot;Parrot EPM & COMP;Billable;ACCEPTED
Output file for month September

svautrot;09/15/2015;Bureau Veritas;Bureau Veritas - LMS ILT;Billable;ACCEPTED
svautrot;09/16/2015;WHO;Testing support;Billable;ACCEPTED
svautrot;09/16/2015;Bureau Veritas;Bureau Veritas - LMS ILT;Billable;ACCEPTED

Screenshot of my tMap 

First i generate 2 variables which are FirstDay_currentDate and LastDay_currentDate
FirstDay_currentDate expression

==> TalendDate.getFirstDayOfMonth(TalendDate.getCurrentDate()) 
LastDay_currentDate expression

==> TalendDate.getLastDayOfMonth(TalendDate.getCurrentDate()) 

For October output file, i do this condition:

TalendDate.compareDate(row24.activityDate,TalendDate.addDate(Var.FirstDay_currentDate,-1,"MM")) >= 0 && 
TalendDate.compareDate(row24.activityDate,TalendDate.addDate(Var.LastDay_currentDate,-1,"MM")) <= 0 

And for September output file, i do this condition:

TalendDate.compareDate(row24.activityDate,TalendDate.addDate(Var.FirstDay_currentDate,-2,"MM")) >= 0 && 
TalendDate.compareDate(row24.activityDate,TalendDate.addDate(Var.LastDay_currentDate,-2,"MM")) <= 0 

Please help me solve this problem, because i don't know why i don't get blue rows
MLarronde;10/31/2015;Parrot;Parrot EPM & COMP;Billable;ACCEPTED
MLarronde;10/01/2015;Parrot;Parrot EPM & COMP;Billable;ACCEPTED
svautrot;09/01/2015;Bureau Veritas;Bureau Veritas - LMS ILT;Billable;ACCEPTED

I'm not sure I fully understand what you are doing here, but the first thing I would check would be the TalendDate.compareDate() sections. You are getting the current date and working with that assuming that it will hold just the day information. It will also contain a time element. You are comparing against other dates which I assume may also have time elements. If you compare 01/01/2000 with 01/01/2000, you expect a result of 0 (the same). But if you compare 01/01/2000 12:02 with 01/01/2000 12:01 you will get 1 or 01/01/2000 12:01 with 01/01/2000 12:02 you will get -1. You need to ensure that you beginning of month and end of month dates are exactly the beginning and end....down to the millisecond.

Dear rhall_2.0?
Your explanation is right, but in my tMap i define date format MM/dd/yyyy so normally everything should be good.
I attach my job to this post
Thanks,

Your start and end dates are defined by getCurrentDate() in your tMap variables. Try something like this for the first day of the month....

TalendDate.getFirstDayOfMonth(TalendDate.parseDate("yyyy-MM-dd",TalendDate.formatDate("yyyy-MM-dd", TalendDate.getCurrentDate())))

For the last day of the month you will actually need to set the time to 23:59:59.9999 or set it to the very next day (beginning of the next month) with a time of 00:00:00.0000 and change your logic slightly to account for that.
