Hello,
I am using
Perl and MySQL to maintain a database of mobile network configuration about 30
tables and millions of rows. Every day, I’ll be importing new configuration
data to the database.
I’d like to create a delta report on which row and which
column are modified, which row is deleted, which row is added. It will be
time-consuming if just comparing each row and column one by one of today's data
and yesterday's data.
Can anyone
give me some good suggestions on this? Thanks in advance!
Cheers,
Jason
