Your correct. Actually I was trying to pass that variable back when it was local to
the sub routine instead of assigning it to a variable outside the routine i.e

There is no problem in this sample code.
But somewhere else in your program you must use $process_date without
declaring it first.

How do i return the end of file message in a subroutine?
I am using an application called Title to kick off jobs instead of using the cron.
I am told that this application doesn't accept SQL embedded inside perl scripts unless
the SQL or perl script returns the end of file message. What method in perl returns
the eof message?
is it
sub myroutine {
$sql = qq( select * from mytable where rownum 1001);
} return eof;
or calling eof( ) i.e.
sub myroutine {
$sql = qq( select * from mytable where rownum 1001);
eof( ) }
return;
or are both of these wrong?

Jason,
Sorry if I wasn't clear in my earlier response to you. If there are NULL
values in your array, you will get this warning when you try joining the
elements of the array.
Example:
[EMAIL PROTECTED]:/usr2/local/cablemanager/etc 01:24 PM]$ perl -e 'use warnings;
use strict; my @array; $array[0] = hi; $array[3] = hello; my $string
= join(,,@array); print $string\n;'
Use of uninitialized value in join or string at -e line 1.
Use of uninitialized value in join or string at -e line 1.
hi,,,hello
Your SELECT statement is returning NULL values. If this is expected and
you still want the join to concatenate the other values into a string,
then ignore the warnings. Within your while loop, throw in a no
warnings 'uninitialized'; to quiet that warning. See:
perldoc warnings
perldoc perllexwarn
Otherwise, you'll have to clean up your SELECT statement and ensure that
all of the fields you're looking for are populated. (add WHERE clauses
and such)
Hope that helps,
- Ed
[Solved] Still getting warning for Use of uninitialized value in join or string (Please Help)..
Actually there are null values coming back periodically from the query. I wasn't aware that the table I was using with the SQL PLUS application is static inside an auxillary database (with the same name) whereas the table that the Perl script is hitting is LIVE and periodically gets updated (by the minute). So the times that I was using the SQL PLUS application, I never saw NULL values there. Sorry for the wasted time.

You should really use 'my' instead or 'our' to declare variables
unless you REALLY REALLY need 'our'. The parentheses are not
required unless you are declaring more then one variable.
our $variable; # no parens required
our ( $var1, $var2 ); # Must use parens
If you had used the warnings pragma you would have been told that
@files, $filename and @record are not being used anywhere which
brings up the next point. You should declare your variables when
you first use them instead of all at the beginning of the program.
#set up for the file naming covention
@times = (localtime)[3..5]; # grabs year/month/day values
^^
I had to do a double take when I read this. The comment says
year/month/day but the code says day/month/year.
$month = $times[1] + 1;
$day = $times[0];
$year = $times[2] + 1900;
You don't really need the @times array at all:
my ( $day, $month, $year ) = (localtime)[3..5];
$month += 1;
$year += 1900;
$truename = Tr0.$month.0.$day.$year._4day.csv\n; #Time stamps each file
once generic file is renamed
Wow, interpolation AND concatenation. Perhaps either:
my $truename = 'Tr0' . $month . 0 . $day . $year . _4day.csv\n;
Or:

Your return statement is OUTSIDE the subroutine!!!
You are returning a value but you DON'T USE IT!!!
You can use the scalar() function to return a scalar value:

What is Use of uninitialized JOIN error?

[The Subroutine] What is Use of uninitialized JOIN error?
Thanks all for the feedback on the WARNING message that I am getting. I know that I
can turn warning off at that moment of code, but I want to know for my own knowledge
what is the warning all about. So, here is the entire sub routine. NOTE** I declared
@records as a global earlier..

Where do you populate @record? Such messages occur when populating an
array with contents of a file (if the file contains a bunch of newlines).
So make sure you know what the array is getting populated with by testing.
Also, you want to join before printing, correct? So swap the lines (but
that is not the cause of the warning).
print OUTFILE $recordlist\n;
$recordlist=join(,,@record);
I will try to view the contents of @record with
foreach my $item (@record) {
print . item: $item\n;

My (variable) versus Our (variable)! Please explain the necessity for use....
Hello folks. I am very thankful for all the help that I am getting here. The only thing is when I get some suggestions, I don't normally get the whys along with it. One in particular is use of my to assign variables, versus using our. Until I can get a Perl scripting class to take, I am teaching myself and sometimes these books don't delve into the simple things. So who can answer this? Thanks, JC
Re: [The Subroutine] What is Use of uninitialized JOIN error?
I used ---print OUTFILE join(,,@record), \n;--- that you suggested and still got
the error.

Explicitly name the columns you want to select on. It could end up
saving you a bunch of headaches in the long run. Also, go into the MySQL
CLI and type your command in, just to make sure you're getting back what

one or more of your columns, which may be causing problems in the join

use Data::Dumper;
print # of columns: . @record . \n;

You may find that your whole array is, in fact, populated with NULL
values...

Excel format from a PERL script
I know this may sound crazy (I have asked crazy question before here so I hope this doesn't get me banned!!) but I have this client who receives automated reports from me every day from a PERL script. The script comes in a .csv format (changed from .txt format) and now they are asking me if I can send it in Excel format. The reason? I had a problem with the server that runs the script, so I used an application to query the database and retrieve the data and it just so happens that the app. exports the data into Excel, whereas my script doesn't. Now they want it in Excel (i guess the few conversion steps cost them too much to hire some one who knows Excel other than save , delete, open, exit). So can Perl save me a mouthful of curse words by doing this SMALL task? Humbly at your mercy, JC

Creating or renaming a file with the creation date included......

RE: Creating or renaming a file with the creation date included......
thanks. I wasn't aware of the rename function. As far as converting to MMDD, can that be done on the fly using localtime()? I am reading online docs now, but nothing talks about it done on the fly i.e. when I call the function up. If not I will work on it some more and follow up with whatever I find out. Regards.

Thanks, JC Using localtime in conjunction with time, you can roll your own little setup. Additionally, if you didn't know already, Perl has a 'rename' function built in, or if you are going to g across file system boundaries you should look at the File::Copy module. perldoc -f rename perldoc -f time perldoc -f localtime perldoc File::Copy Additionally you might consider using the Compress::Zlib for compression of the logs, and you should definitely consider changing your naming convention to be MMDD as that will allow the files to sort properly in their directory. http://danconia.org -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

the file that i am trying to send has been properly created, but MIME::Lite isn't
emailing it. Its emailing me a textfile with the same name as the file onthe server,
but without the data in it. Here is the new code:

What the 'FETCH' is up with Perl?
Hello all. Can someone tell me what is the difference in the various ways to FETCH data from a database? I bought like 3 books and they don't really go in depth with the reasons why there are several of them, and what happens if you interchange them with different scenarios. Thanks. Here are the ones that I am asking about: Fetch Fetchrow Fetchrow_array fetchall_arrayref fetchrow_hashref Any others please add explanation. Thanks. JC - Do you Yahoo!? Friends. Fun.

I need to use data collected from a query
I am writing a script that'll query the database, and I want to do 2 things:
1. Print it to screen with my desired format.
If I like what I see:
2. Print it to a file.
Any suggestions?
Here is my query for writing to a file:

chomp (my $database_name1=STDIN);
print Enter the username: ;
chomp (my $username=STDIN);
print Enter the password: ;
chomp (my $passwd=STDIN);
#Must define the database here:
my $database=dbi:Oracle:$database_name1;
#Connecting to the database:database=database_name1','$username','$passwd'
my $dbh = DBI-connect($database, $username, $passwd)
or die Can't connect to Oracle database: \n $DBI::errstr\n;

Connecting to Oracle over network
Hello. I am using Windows 2000 to connect to an Oracle database over the company
network. I have the DBI/DBD drivers installed on my computer. I want to connect using
the script below. When i run the script, it doesn't come back with anything. It just
goes to the command prompt. Can someone tell me how to do this, and what env variables
need to be set and where? I am not using any proxies btw.
Regards,
JC
