I have a sample comma separated file as having date data in field # 5 and field #8. Field # 4 and 7 (fields before the date field) are indicators:
This is just a sample data, the actual file may have n number of date fields.
I need to update field #5 (depending on the value in field # 4 (indicator field)) and field #8 (depending on the value in field#7) and so on as :
1. If field # 4 = 0 and field # 5 <> 0 (say data is : 991213), then append '19' to the string in field # 5 and make the final value
as : 1999-12-13. This is for years before 2000
2. If field # 4 = 0 and field # 5 = 0 (say data is : 0), then the final value as : 0001-01-01
3. If field # 4 = 1, then
a. check if field # 5 has length = 5, then (for data say: 51213), append '200' so that the final value should be 2011-12-13
b. Else, (for data say : 111213), append '20' so that the final value appears as : 2011-12-13.
Input parameters to the script :
$1 : file name
$2 , $3, ........ this depends on the number of date fields which need to be transformed.
I have written the following code:
I am able to transform the data for Field # 5 only.
Could you please suggest a better approach for this requirement such that I am able to transform the data for field # 8 as well.
Hi Friends,
I'm working on a perl script, which seems to be simpler. But I'm very new to PERL scripting.
I have a comma separated data file, from which I need to extract only the seventh field data out of available twenty fields to an array using perl.
Any help would be much appreciated.

for ($j = 0; $j < $i; $j++) {
echo "column $j
";
$fieldname = pg_field_name($res, $j);
echo "fieldname: $fieldname
