/**
 * Query an SQL and return a {@link java.sql.ResultSet} of the result.
 * If the SQL file contains {@code %s} in the query, the parameters
 * specified will replace {@code %s} in the query. Remember that if the query
 * is not a {@code SELECT, EXPLAIN, CALL, SCRIPT, SHOW, HELP} query, this will ALWAYS return null.<br>
 * In the event that the queries are different per database, prefix
 * <code>S:</code> at the beginning of the query followed by the database type and another
 * colon./*from w w w.ja v a  2s.  co  m*/
 * @param queryfilename sql filename to use
 * @param params parameters for sql file
 * @return ResultSet of SQL query (or null... if there really is nothing good.)
