Hello experts, Im a Perl newbie and Im looking for a way to compare rows returned in a sql statement and keep the row with the most current date. Below is a simplified version of the rows and also a copy of the code I wrote but it doesnt work.
ID Date 13 10102005 13 09152005 13 11052005 200 11012005 200 11152004 Here's the code I wrote: foreach $data1(@data_241) { @compare1 = split($data1); foreach $data2(@data_241) { @compare2 = split($data2); if ($compare1[0] == $compare2[1]) { if ($compare1[1] > $compare2[2]) { print NEW "@compare1"; } } } }
So in the example, I need to keep only ID 13 with a date of 11052005 and ID 200 with the date 11012005. Thanks in advance....
