[resolved] tSortRow with RowNumber

Hello Talend Team,
I have csv delimiter file which contains column accountname and accountaddress. I want unique accountname with only one address details.
my csv data file
accountname accountaddress
account1 add1
account1 add2
account2 add1
account2 add2
account1 add3
I want output file like
accountname accountaddress
account1 add3
account2 add2
So I have designed my job like
tFileInputdelimiter --------------->tSortRow-------------->tUniqueRow---------------->tFileOutputdelimiter
(accountname) (accountname)
but its gives me output file as mentioned below with first address instead of last address.
accountname accountaddress
account1 add1
account2 add1
please help me how I achieve output file with last address only or is there any way to sort by row number?
Thanks,
Nitin

Hi
Yes, you can add an row number for each and sort by the row number. To do it:
1. Add a new column on the output table on tMap, let's call it 'row_number', set its expression as Numeric.sequence("s1",1,1)
2. On tSortRow component, sort by row_number with desc order.
Best regards
