NAME

DBD::Sponge - Create a DBI statement handle from Perl data

SYNOPSIS

  my $sponge = DBI->connect("dbi:Sponge:","","",{ RaiseError => 1 });
  my $sth = $sponge->prepare($statement, {
          rows => $data,
          NAME => $names,
          %attr
      }
  );

DESCRIPTION

DBD::Sponge is useful for making a Perl data structure accessible through a standard DBI statement handle. This may be useful to DBD module authors who need to transform data in this way.

METHODS

`connect()`

  my $sponge = DBI->connect("dbi:Sponge:","","",{ RaiseError => 1 });

Here's a sample syntax for creating a database handle for the Sponge driver. No username and password are needed.

`prepare()`

  my $sth = $sponge->prepare($statement, {
          rows => $data,
          NAME => $names,
          %attr
      }
  );

The $statement here is an arbitrary statement or name you want to provide as identity of your data. If you're using DBI::Profile it will appear in the profile data.

Generally it's expected that you are preparing a statement handle as if a select statement happened.
$data is a reference to the data you are providing, given as an array of arrays.
$names is a reference an array of column names for the $data you are providing. The number and order should match the number and ordering of the $data columns.
%attr is a hash of other standard DBI attributes that you might pass to a prepare statement.
Currently only NAME, TYPE, and PRECISION are supported.

BUGS

Using this module to prepare INSERT-like statements is not currently documented.
