Hello Monks,
I would like to minimize the amount of code lines and I would like to query a database using DBI and first find out the criteria to search by:


$query="select distinct number from first_table";
$sth = $dbh->prepare($query);
$sth->execute() or die "$DBI::errstr";

while ( ($row) = $sth->fetchrow_array() )
{
push (@query_results, $row);

}

Then here is when i am confused. I would like to do a foreach loop on query results and place it into a hash of arrays:

foreach $line(@query_results)
{
select record_ids from second_table where number= $line;

####not sure what the code is next to create my hash of arrays based on each number as there could be more than one record id and each "number" mill have more than one hash of array value assigned to them####

}

Thanks so much!
