it says that ERROR 1690 (22003): BIGINT UNSIGNED value is out of range. If I replace 'where delta > 1' with 'having delga > 1' then it also works. The question is: Why? NextID, if exists, is at least one greater than ID... ...
mysql 当两个字段想减时,如果其中一个或两个字段的类型的unsigned无签名类型,如果想减的值小于0则会报错(BIGINT UNSIGNED value is out of range) 测试: selectcast(1asunsigned)-2select0-cast(1asunsigned) 解决办法: 一、修改字段类型 二、使用cast函数转字段为signed类型 selectcast(1assigned)-2...
BIGINT UNSIGNED value is out of range in..的解决方法 今天在做一个功能的时候,用到两个时间戳相减来做查询条件,由于其两个字段都是unsigned的,并两个的大小是不一样。所以直接相减查询的时候, 就出现ERROR 1690 (22003): BIGINT UNSIGNED value is out of range in..的错误,因为结果可能会出现负数。。。
1 当两个字段想减时,如果其中一个或两个字段的类型的unsigned无签名类型,如果想减的值小于0则会报错(BIGINT UNSIGNED valueisoutof range) 处理办法: 例:selecta - bfrom table 改:selectif(a >= b, a - b, - (b - a))from table
执行上述SQL语句,我们可能会收到一个错误提示:BIGINT UNSIGNED value is out of range in。这是因为@a和@b的和超出了INT类型的范围。 解决方案 使用BIGINT类型 为了避免范围溢出的问题,我们可以将INT类型的变量转换为BIGINT类型: SET@a=2147483647;SET@b=3600;SELECTCAST(@aASBIGINT)+@b; ...

Yes, you are right. In this case the auto_increment option won't play, only it was easier to write 'serial' instead of 'bigint unsigned'. Anyway, some ID values are given and they need not be consecutive. Better to say, they are NOT consecutive, as you can see the insert values....
