Re^5: My doubts about using fetchall

You cannot. My proposal only works for simple column names. Do you really need to pass the columns names? Can you not use

my $rs = $sth->fetchall_arrayref({});
[download]

without specifying the columns? According to the documentation it should work but I do not have your database to test it. This way everything would be controlled by your sql only.

In this case I will use the sample below for SQL queries that require a more complex call, yes I could use this: `my $rs = $sth->fetchall_arrayref({});` [download] `... my $sql = "select id, account_number, CONVERT(VARCHAR(10),date,101) a +s date from my_table where id <>'' order by date desc"; my @columns = qw( id account_number box ); my $results = $self->_all_data($sql, \@columns); ...` [download]	[reply] [d/l] [select]

If you have a more advanced query like this one: `my $sql = "select id, account_number, CONVERT(VARCHAR(10),date,101) as + date from my_table where id <> '' order by date desc";` [download] Then you can call the version of _all_data() that I gave above as either: `my @columns = qw( id account_number date ); my $results = $self->_all_data($sql, \@columns);` [download] or `my $results = $self->_all_data($sql);` [download] They will both get the same result set.
