So here is what i want to do: Monitor a bunch of tables in a MySQL database, append time stamps to WHEN the values changed, and then render the result in a graph.
Dear Monk,
I'm a bit confused as to what you are trying to do. Let me step through your code though and offer some commentary.
my $database = 'co_sysdev';
my $server = 'devqa_dbm.hq.co.corp';
my $user = 'web';
my $passwd = '3br!';
my $row = "";
Hope those aren't really production passwords. Never post such to this site as Google does a fine job of spidering this site from time to time making this sort of thing easy to find.
my $homologs = DBI->connect("dbi:mysql:database=co_sysdev;host=devqa_d
+bm.corp;port=3310",'username','password');
So.. what were those other lines for?
#my $query_params = "select * from system_params";
# render the result in a graph format
# save it locally in a csv format, to be used later for report
my $query_coding_event = "select * from coding_event";
my $query_params = "select * from co_event";
#my $query = "select * from n_batch where status = 'started'";
#my $query = "select * from n_batch";
#my $query = "select id,customer_id,location_id,submitter,n_notes,hand
+le from submission_batch where id is not null";
#my $query = "select id,customer_id,location_id,submitter,n_notes,hand
+le from submission_batch where id is not null";
#my $query = "describe submission_batch";
#my $query = "show tables";
my $sql_params = $homologs->prepare($query_params);
when posting code to the PM remember to remove unnecessary lines for readability. This is what it should have looked like IMHO:
my $query_coding_event = "select * from coding_event";
my $query_params = "select * from co_event";
my $sql_params = $homologs->prepare($query_params);
so we can see what you are trying to run.
while (my $row = $sql_params->fetchrow_arrayref) {
#print join("\t", @$row), "\n";
print join(@$row), "\n";
print @$row . " \n";
}
Let's start with the line print join(@row),"\n";. Is this doing what you expect? What is going to happen is join is going to take the first element in your array and use it for a separator for the rest of the array. Here's an example of what I am saying:
$ perl -e 'print join(qw/a b c d e f/),"\n"'

Not sure that's what you were after. Then you do print $@row . "\n";, why? Looks to me like you are repeating yourself.
i used DBI, and was able to connect to the database and get some table column values:
So.. what are you trying to do with those values? What have you tried? What was the result?
