in thread Undefined Array Reference

The reason for that is a query result from a database, each array ref, since I can not join these tables, are each from these tables, and I don't know how many records each one will be returning, that is the reason for this sample code.

I'd really like to know why you can't join the tables...	[reply]

The tables are too big, they are already a logic file from 3 different tables each. Thats the only way, I have to get the values from the first and after finding the account numbers I can get the rest from the other table, manipulate the results in the array ref and format a report	[reply]

Perhaps indexes on your tables could help. Or instead of trying to turn Perl into a database, create subsets of your tables in temp tables and query those. I know from personal experience that this type of processing is best left to databases even though Perl is much cooler than SQL	[reply] [d/l]
