Hi, I'm hoping someone can help.

I am writing a script which I want to connect to different schemas and run some common queries. I've decided to use DBI for the connectivity and a hash to store the connectivity detail. My question is does DBI allow you to store all details in a single value or do you need to list each value separately.

Here is the code I am using

 #!/usr/local/bin/perl -w
use strict;
use DBI;                # for database connectivity



my %db_conn = (
   a_manager => "DBI:Oracle:host=hostname1;sid=ABCDB01;port=1300','a_m
+anager','a_manager',",
   b_manager => "DBI:Oracle:host=hostname1;sid=ABCDB01;port=1300','b_m
+anager','b_manager',",
   c_manager => "DBI:Oracle:host=hostname1;sid=ABCDB01;port=1300','c_m
+anager','_manager',",
   d_manager => "DBI:Oracle:host=hostname1;sid=CBADB01;port=1300','d_m
+anager','d_manager',",
   );

for my $owner (keys %db_conn) {

print "Running $owner stats_table creation\n";

my $data_source = $db_conn{$owner};

print "$data_source\n";

my $query = qq (
        select * from cat
               );
my $dbh = DBI->connect($data_source) or die "Couldn't connect to datab
+ase: " . DBI->errstr;

my $sth = $dbh->prepare($query)
                or die "Couldn't prepare statement: " . $dbh->errstr;

$sth->execute() or die "Couldn't execute statement: " . $sth->errstr;

}

I am currently getting the error ORA-24327: need explicit attach before authenticating a user (DBD ERROR: OCISessionBegin)

If, however, I pass the values as individual values it is successful
