Re^2: Process and combine two CSV files into one

in thread Process and combine two CSV files into one

I'm just not getting this join right. If I do a

my @row = $dbh->selectall_arrayref("SELECT IP, ServerName, Domain, Day
+sUptime, OS, RAM, OSSP, InstallDate, CPUSpeed, CPUCount, CPUType FROM
+ hosts LEFT JOIN info ON hosts.IP = info.IP");
[download]

My 2 tables get joined. The only issue is that I get a warning:

Execution ERROR: Ambiguous column name 'IP' called from /usr/lib/perl5
+/vendor_perl/5.8.6/i586-linux-thread-multi/DBI.pm at 1557.
[download]

But if I try and change a column name, every field returned contains the "IP" value, regardless of what the true value should be.

Also, when I try to join a 3rd table it takes a long time. The 2 tables are done in less than 15 seconds. When I add the 3rd table it's just over 5 minutes.

my @row = $dbh->selectall_arrayref("SELECT IP, ServerName, Domain, Day
+sUptime, OS, RAM, OSSP, InstallDate, CPUSpeed, CPUCount, CPUType, Par
+titionFree FROM hosts, disks LEFT JOIN info ON hosts.IP = info.IP AND
+ hosts.IP = disks.IP");

In the end, I want ALL data from hosts, and the relevant data from the other tables.
Once I have the these 3 tables combined, I'd like to print them out in a CSV type format. How do I do that?
