Hello all,
I don't know why my code isn't working. The script I have has been running for months, almost a year without a problem on an NT server, now I'm just cleaning it up to run on an AIX machine. I do a DBI connection and get data from an Oracle database. Now I want to use the data that is extracted from the db table.
Remember this has worked on NT for a while with no errors.
The following code has been edited for printing here online, but the part that doesn't work is it is not getting into the 'while' loop where '->fetch' is.
Thank you in advance for the help.

print "2 ....... set datestamp: ".$datestamp."\n";
print "2 a ...... was able to open temp flag \n";
print "3......... was once flock'd \n";

Any ideas? I've looked through a few books and online and now I come here for help. Thanks again!
