DBIx::SimpleGoBetween - DBI Wrapper interface


  use DBIx::SimpleGoBetween;
  use DBI;

  my $dbh=DBI->connect(blah blah blah);

  my $db=DBIx::SimpleGoBetween->new(\$dbh);

  # returns the first column of the first row of your query
  $count=$db->get_scalar('select count(*) from table_a');

  # fetches the entire result set as a single list
    'select max(column_a) ,sum(column_a) from table_a'

  # returns a list reference of list references
  # each list reference represents a row from the result set
    'select * from table_a'

  # returns a list reference of hash references
  # each hash reference represents a row from the result set
    'select * from table_a'

  # does a prepare then executes the query with the list reference 
  # provide by the 2nd argument
  $db->sql_do('delete from table_a where column_a=?',[$value]);

  # Callback
  # code_ref: is called on a per row basis, arguments based on 'type'
  # type: array,hash,array_ref,hash_ref
    'sql',[execute list],[prepare_args],'type',\&code_ref


DBIx::SimpleGoBetween acts as a go between for DBI and any other development interfaces you use. This package has no iterators, no error checking. It simply returns the result sets in one of many data structure formants.

Odds are your result does not need to be processed, just placed in a structure in the order it was retrieved, if so then this is the module you are looking for.

Example using HTML::Template

  use DBI;
  use DBIx::SimpleGoBetween;
  use HTML::Template;

  my $dbh=DBH->connect();
  my $db=DBIx::SimpleGoBetween->new(\$dbh);
  my $tmpl=HTML::Template->new(filename=>'file.tmpl');

    total_rows=>$db->get_scalar('select count(*) from table_a')
    ,tmpl_loop=>$db->get_list_of_hashes('select * from table_a')
