Return the first object that matches the PreparedQuery or null if none.

Throws:

SQLException

queryForAll

public List<T> queryForAll(DatabaseAccess jdbcTemplate)
                    throws SQLException

Return a list of all of the data in the table. Should be used carefully if the table is large. Consider using the Dao.iterator() if this is the case.
