bigint 当超过mysql的整形的时候,就会导致溢出,mysql可能会将错误信息带出。这里user()是字母默认为0 取反以后+1可能就会导致异常。 报错特征 BIGINT UNSIGNED value is out of range in 不需要函数 ,直接让他报错出来 select%20(~(select%20*%20from(select%20user())x)%2b1,1) 也可以利用函数的参数让...

用cast(num1 as signed)-cast(num2 as signed) 解决报错BIGINT UNSIGNED value is out of range in... SQL中:两数相减来做查询条件,由于两个字段都是unsigned的,并两个的大小是不一样。所以直接相减查询的时候,会出现负数,导致报错(Mysql不报错) ERROR 1690 (22003): BIGINT UNSIGNED value is out of r...

所以,如果我们对~0进行加减运算的话,也会导致BIGINT溢出错误。 代码语言:javascript 复制 mysql>select1-~0;ERROR1690(22003):BIGINTvalue is outof rangein'(1 - ~(0))'mysql>select1+~0;ERROR1690(22003):BIGINTUNSIGNEDvalue is outofrangein'(1 + ~(0))' ...
