And here, my friends, is the gaping charred hole I so wanted to cover up!
trà UNION ALL SELECT NULL,NULL-- eNwk.
-1 or 1=1 and (SELECT 1 and ROW(1,1)>(SELECT COUNT(*),CONCAT(CHAR(95),CHAR(33),CHAR(64),CHAR(52),CHA.
char *ultoa( unsigned long value, char*string, int radix ); под radix понимают основание преобразуемого числа int value в символьную строку.
定义了数组a[4],其中a,&a,&a[0]都是数组的起始地址。 但是步长有区别,也就是指向的类型不同. a等同于a+0等同于&a[0],是指向数组第一个元素的指针,步长为指向的元素所占用的地址空间为sizeof(int) 。
(select+char(113)+char(112)+char(106)+char(112)+char(113)+(select+(case+when+(9801=9801)+then+char(49)+else+char(48)+end))+char(.
peek-char obtains the next character in input-stream without actually reading it, thus leaving the character to be read at a later time. It can also be used to skip over and discard intervening characters in the input-stream until a particular character is found.
