dbd::sponge

DBD::Sponge(3)						User Contributed Perl Documentation					    DBD::Sponge(3)

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
	     }
	 );

       o   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.

       o   $data is a reference to the data you are providing, given as an array of arrays.

       o   $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.

       o   %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.
