I have a program to fetch customer data as output where input values can be any of these two mentioned below.
1. date range (from and to date value)
2. customer name
recently we had a migration from AIX platform to Linux. The fact is this program works perfectly in AIX platform, but after migration, seems like for date rang no output is shown. I got a comment to check whether it is data issue or not. What does it mean "data issue". And what can be the reason for the same program to not work on a different platform?Any help would be appreciated.
What I have tried:
I tried the query which it uses to fetch data on db server and it gave output also. But the same when it fetches from program is not giving output
