/**
* Performs a query on a table one chunk at a time and returns an array of
* every fetched row.
*
* This function will break up a non-SELECT query (like an INSERT, UPDATE, or
* DELETE) into smaller queries and should be used when performing an operation
* that can take a long time to finish. Using several small queries will ensure
* that the table will not be locked for too long.
*
* @see Piwik_Sql::segmentedQuery
*
* @param string $sql The SQL to perform. The last two conditions of the WHERE
* expression must be as follows: 'id >= ? AND id < ?' where
* 'id' is the int id of the table.
* @param int $first The minimum ID to loop from.
* @param int $last The maximum ID to loop to.
* @param int $step The maximum number of rows to scan in each smaller query.
* @param array $parameters Parameters to bind in the query, array( param1 => value1, param2 => value2)
* @return array
