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.
My strong guess is that you are running into line-ending issues. Make
sure that you know what the line endings are in the CSV file, which will
vary depending on whether the file was created on doze or *nix. Set the
line ending (csv_eol) either in the connect or in the database handle:
my $dbh = DBI->connect( 'dbi:CSV' ... { csv_eol => "\012" }
DBD::CSV defaults to windows line endings ("\015\012"). DBD::CSV can
use either line ending (or other eols) on either platform, as long as
it's the correct line ending for the data file being used which may
depend on whether or not you transferred the file from one platform to
another using a line-ending aware process.

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
