SET@a=2147483647;-- INT的最大值SET@b=3600;-- 一个小时的时间戳SELECT@a+@b; 1. 2. 3. 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...
然而在实际使用中 UNSIGNED可能会带来一些负面的影响 示例如下 mysql> CREATE TABLE t ( a INT UNSIGNED, b INT UNSIGNED ) ENGINE=INNODB; Query OK, 0 rows affected (0.06 sec) mysql> INSERT INTO t SELECT 1,2; Query OK, 1 row affected (0.00 sec) Records: 1 Duplicates: 0 Warnings: 0 mysql...

步骤1: 将字段类型由BIGINT UNSIGNED转换为BIGINT 在MySQL中,我们可以使用ALTER TABLE语句来修改字段类型。下面是需要执行的代码: -- 修改字段类型为BIGINTALTERTABLEyour_table_nameMODIFYyour_column_nameBIGINT; 1. 2. 这条代码会将指定表中的指定字段类型由BIGINT UNSIGNED修改为BIGINT。 步骤2: 执行字段相减...
