Problems using the DBI class to access CSV files.

I've been using the DBI class for a while now & I'm trying to port some code from a Windows environment where it is working perfectly to a Unix environment where it's not really working.  I've also reviewed the Perl DBI book again & see nothing about this type of problem.  It seems that it's just the CSV type of database that is having issues.

I'm trying to parse pipe separated log files to search for data so that actions can be taken based on what I find in the log files.

A sample log file:

TIME|Status|Description|
17:15:51|OK|No Problems|
17:31:12|Warning|Skipped file abc|
18:45:03|ERROR|Can't read file xyz|

Afraid that it might be a bug in my code, I began using "dbish" to test out my queries.  But I get the same problems as in my code.  I find all 3 rows in Windows, but I always find Zero rows on the Unix platforms.

On Windows:
M:\...\logs>dbish

'18:45:03','ERROR','Can't read file xyz',''

[3 rows of 4 fields returned]

But if I attempt to do the same thing against AIX Unix, I get

Can anyone offer suggestions?
