DESCRIPTION

TO BE COMPLETED

METHODS

select

  # Get all objects in list context
  my @list = CPANDB::Requires->select;
  
  # Get a subset of objects in scalar context
  my $array_ref = CPANDB::Requires->select(
      'where distribution > ? order by distribution',
      1000,
  );

The select method executes a typical SQL SELECT query on the requires table.

It takes an optional argument of a SQL phrase to be added after the FROM requires section of the query, followed by variables to be bound to the placeholders in the SQL phrase. Any SQL that is compatible with SQLite can be used in the parameter.

Returns a list of CPANDB::Requires objects when called in list context, or a reference to an ARRAY of CPANDB::Requires objects when called in scalar context.

Throws an exception on error, typically directly from the DBI layer.

count

  # How many objects are in the table
  my $rows = CPANDB::Requires->count;
  
  # How many objects 
  my $small = CPANDB::Requires->count(
      'where distribution > ?',
      1000,
  );

The count method executes a SELECT COUNT(*) query on the requires table.

It takes an optional argument of a SQL phrase to be added after the FROM requires section of the query, followed by variables to be bound to the placeholders in the SQL phrase. Any SQL that is compatible with SQLite can be used in the parameter.

Returns the number of objects that match the condition.

Throws an exception on error, typically directly from the DBI layer.

  if ( $object->distribution ) {
      print "Object has been inserted\n";
  } else {
      print "Object has not been inserted\n";
