Question Need help in printing a sql query in perl
Hi All,

I have the following sql query

select abcd from udbadm.log where xyz='1'.

I have 16k queries similar to this with different values for xyz.

I want to print the values of 'abcd' for each row.

I have the following perl code, but not sure how i can print that particular column

open(OUTPUT, ">/tmp/output.txt") || die ("Can't open\n");
open (FILE, "/tmp/commands.sql") || die ("Can't open commands.sql\n");
while (<FILE>)
{
$sql = $_;
chomp $sql;
$update = $dbh->do($sql);
if($update)
{
print OUTPUT "Success:Now executing $sql\n"; - Here i want to print 'abcd' instead of the query for each run
}
else
{
print OUTPUT "Failure:";
$update = null;
$sql=$_;
$update = $dbh->do($sql);
print OUTPUT "Now executing $sql\n";
}
}


Appreciate your help. Thanks in advance
