Hi Srinvas

The key is to have the date in reverse format, in other words Year, Month
Day as that will put the dates in the correct order. For example, suppose
you had the following dates:

01/11/07
02/10/07
03/09/07

Sequencing them in DD/MM/YY doesn't give you the correct order or records.
If you tried to select records from 01/09/07 to 30/09/07 the first record
you would read would be the 01/11/07 which isn't in the date range.
Depending on how the program was written you may or may not read any more
programs in the loop.

If you store the dates on your file in YYMMDD order (or better still, use a
date type field in *ISO format - YYYY-MM-DD) then the records would be in
the following order:

2007-09-01
2007-10-02
2007-11-03

Which is the correct sequence. In your program you can now use SETLL to
position to the 'first' record in your range and have a loop that tests the
record you've read against the last date of your range. For example:

FMyFile IF E K Disk

D FromDate s d DatFmt(*ISO)
D ToDate s d DatFmt(*ISO)

C FromDate SetLL(e) MyFile
C DoU (RecordDate > ToDate) or (%Eof(MyFile))
C Read(e) MyFile
C If Not %Eof(MyFile) and (RecordDate <=
ToDate)
C ...
C ... do some processing ...
C ...
C EndIf
C EndDo

C Eval *InLR = *On
C Return

Here the assumption is that MYFILE is keyed on RECORDDATE order and that
RECORDDATE is a date type field in*ISO format. The DOU statement tests to
see whether or not you need to read any more records and the IF statement
makes sure that the record you read is in the correct range.

All the best

Jonathan

Hi every one,



How do I Select from Date To - To Date in RPGLE



Say suppose I have 20 records in a Physical File and I have 8 fields in
it.

Now I want to retrieve from Dates To - To Date.



I tried with the following way created a logical file of eight fields
all of them are keyed



In RPGLE program I have created KLIST ( KEY AND KEY1)



C KEY KLIST

C KFLD FDD

C KFLD FMM

C KFLD FCC

C KFLD FYY

C*

C KEY1 KLIST

C KFLD TDD

C KFLD TMM

C KFLD TCC

C KFLD TYY



With the help of KEY & Chain I can able to set pointer to from date and
read the record.

But how do I stop at To-Date.



0004.43 C KEY CHAIN DSPREC 90





Please Can any one guide me on this issue.



Thanks in Advance

Srinivas













I want to retrieve records from 10 to 15, I can able to set pointer and

Thanks in Advance
