Hi Monks!
In my application I want to have one sub to use just to retrieve all the information I need from my db table. The issue is that I am using fetchall_arrayref. In the first call to this sub I am retrieving all the records so I am passing all the column names I need to the sub, it works fine, but on my second call I don’t need all the columns. My question is, can I pass only the rows I need or if there is a way so fetchall_arrayref will take whatever will be passed by the sql query.
Here is the sub with all the rows been queried from the db table.

# Retrieve all the data to process from the database

sub _all_data {
    
    my $self = shift;
    my $sql = shift;
    
    my $sth = $mssql_dbh->prepare($sql);
       $sth->execute() || die $sth->errstr;

    # array indices for each returned row
    my $rs = $sth->fetchall_arrayref(
        {
            id       => 1,
            account_number    => 1,
            box             => 1,
            number             => 1,
            address  => 1,
            type  => 1,
            quantity       => 1,
            count   => 1,
            new_line   => 1,
            date     => 1,
        }
    );

    return $rs;
}

This first call as example, if I am retrieving all the records by calling all the rows from the table, this works fine.

...
my $sql  = "select id, account_number, box,number,address, type, quant
+ity, count, new_line, date
                from my_table where id <>''
                order by date desc";

    my $results = $self->_all_data($sql);
...

This call, I would only need to retrieve 3 rows, but I would like to still use the same sub _all_data(), thats the issue, cause the _all_data() is expecting all the columns and I only need 3 this time.

...
my $sql  = "select id, account_number, date
                from my_table where id <>''
                order by date desc";

    my $results = $self->_all_data($sql);
...

Thanks for helping!
