I am executing following SELECT query from my perl program and I am using DBI interface
my $test=$dbh->prepare("SELECT AVG(diff) FROM data WHERE key1='s' and key2='i'");
$test-> execute();

The above query , if executed in SQL query browser generate average result of column 'diff' which I want to store in variable in perl for further use

I have idea of dump_results function provided by DBI as one of the option but doesn't seems to work for me

Try this..

@row = $sth->fetchrow_array();

$myVar = $row[0];

Open in new window
