> This program
> {code:sql}
> SELECT SUBSTRING('string' FROM 2 FOR 2147483646)
> {code}
> returns "" instead of "tring".
> This happens because of an overflow in the SqlFunctions substring function:
> {code:java}
> public static String substring(String c, int s, int l) {
> int lc = c.length();
> int e = s + l; // <<<< OVERFLOW here
> {code}
