NAME
    DBIx::Wrapper - A wrapper around the DBI

SYNOPSIS
    use DBIx::Wrapper;

    my $db = DBIx::Wrapper->connect($dsn, $user, $auth, \%attr);

DESCRIPTION
    DBIx::Wrapper provides a wrapper around the DBI that makes it a bit
    easier on the programmer. This module allows you to execute a query with
    a single method call.

METHODS
  connect($data_source, $username, $auth, \%attr)
    Connects to the given database. These are the same parameters you would
    pass to the connect call when using DBI directly.

  new($data_source, $username, $auth, \%attr)
    An alias for connect().

  newFromDBI($dbh)
    Returns a new DBIx::Wrapper object from a DBI object that has already
    been created. Note that when created this way, disconnect() will not be
    called automatically on the underlying DBI object when the DBIx::Wrapper
    object goes out of scope.

  getDBI()
    Return the underlying DBI object used to query the database.

  insert($table, \%data)
    Insert the provided row into the database. $table is the name of the
    table you want to insert into. %data is the data you want to insert -- a
    hash with key/value pairs representing a row to be insert into the
    database.

  replace($table, \%data)
    Same as insert(), except does a REPLACE instead of an INSERT for
    databases which support it.

  update($table, \%keys, \%data)
    Update the table using the key/value pairs in %keys to specify the WHERE
    clause of the query. %data contains the new values for the row(s) in the
    database.

  smartUpdate($table, \%keys, \%data)
    Same as update(), except that a check is first made to see if there are
    any rows matching the data in %keys. If so, update() is called,
    otherwise, insert() is called.

  nativeSelect($query, \@exec_args)
    Executes the query in $query and returns a single row result. If there
    are multiple rows in the result, the rest get silently dropped.
    @exec_args are the same arguments you would pass to an execute() called
    on a DBI object.

  nativeSelectMulti($query, @exec_args)
    Executes the query in $query and returns an array of rows, where each
    row is a hash representing a row of the result.

  nativeSelectLoop($query, @exec_args)
    Executes the query in $query, then returns an object that allows you to
    loop through one result at a time, e.g.,

        my $loop = $db->nativeSelectLoop("SELECT * FROM my_table");
        while (my $row = $loop->next) {
            my $id = $$row{id};
        }

  nativeQuery($query, @exec_args)
    Executes the query in $query and returns true if successful. This is
    typically used for deletes and is a catchall for anything the methods
    provided by this module don't take into account.

  nativeQueryLoop($query)
    A loop on nativeQuery, where any placeholders you have put in your query
    are bound each time you call next(). E.g.,

        my $loop = $db->nativeQueryLoop("UPDATE my_table SET value=? WHERE id=?");
        $loop->next([ 'one', 1]);
        $loop->next([ 'two', 2]);

  newCommand($cmd)
    This creates a literal SQL command for use in insert(), update(), and
    related methods, since if you simply put something like "CUR_DATE()" as
    a value in the %data parameter passed to insert, the function will get
    quoted, and so will not work as expected. Instead, do something like
    this:

        my $data = { file => 'my_document.txt',
                     the_date => $db->newCommand('CUR_DATE()')
                   };
        $db->insert('my_doc_table', $data);

  debugOn(\*FILE_HANDLE)
    Turns on debugging output. Debugging information will be printed to the
    given filehandle.

  debugOff()
    Turns off debugging output.

  setNameArg($arg)
    This is the argument to pass to the fetchrow_hashref() call on the
    underlying DBI object. By default, this is 'NAME_lc', so that all field
    names returned are all lowercase to provide for portable code. If you
    want to make all the field names return be uppercase, call
    $db->setNameArg('NAME_uc') after the connect() call. And if you really
    want the case of the field names to be what the underlying database
    driveer returns them as, call $db->setNameArg('NAME').

  There are also underscore_separated versions of these methods.
        E.g., nativeSelectLoop() becomes native_select_loop()

TODO
    Allow creation from existing DBI handle.
    Logging
    Allow prepare() and execute()
