# DBD::Sponge

Create a DBI statement handle from Perl data

## SYNOPSIS

```perl
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()

```perl
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()

```perl
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.  TYPE defaults
    to SQL\_VARCHAR.  PRECISION will be lazily computed if not supplied.

## BUGS

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