Fatal error on SQL with DELIMITER statements

[ktarasov]

Hi.

The parser throw fatal error on SQL with DELIMITER statements.
Test code:

<?php

use Kodus\SQLSplit\Splitter;

require 'vendor/autoload.php';

$sql = <<<SQL
	DELIMITER $$

	CREATE OR REPLACE FUNCTION `someFunc`(`percent` INT UNSIGNED) RETURNS double(15,2)
		NO SQL
	BEGIN
		IF percent = 100 THEN
			RETURN 0.00;
		END IF;

		RETURN 100;
	END
	$$

	DELIMITER ;
SQL;

$statements = Splitter::split($sql);
var_dump($statements);

Output:

PHP Fatal error:  Uncaught RuntimeException: unexpected input: expected delimiter character(s), at: 201, got: ";" in /home/kvt/Dev/tmp/tst/testSQL/vendor/kodus/sql-split/src/Tokenizer.php:320
