BIT(M)占用存储空间是(M+7)/8个字节,这个计算方式与ENUM、SET类似,简单的说如果存储1到8位则占用1个字节存储空间,如果存储9到16位则占用2个字节存储空间,以此类推。 可以使用等值的十进制整数或者b'value'的形式给二进制字段赋值,BIT类型会将整数转化为二进制数来存储。如果存储时数据位数小于字段指定位数则前...
value rounded to the nearest 8-bit signed integer. If value is halfway between two whole numbers, the even number is returned; that is, 4.5 is converted to 4, and 5.5 is converted to 6. Exceptions 展开表 Exception TypeCondition OverflowException value is greater than Byte.MaxValue or les...
数值型允许设置成USIGNED(无符号)SIGNED和(带符号)属性,默认为SIGNED As of MySQL 8.0.17, the UNSIGNED attribute is deprecated for columns of type FLOAT, DOUBLE, and DECIMAL (and any synonyms) and will be removed in a future MySQL version. Consider using a simple CHECK constraint instead for su...

Signed values implicitly convert to unsigned values by adding2wto the signed value. T→UUMIN=0→01→1⋮2w−1−1→2w−1−1=TMAX−1→(−1)+2w=UMAX−2→(−2)+2w⋮TMIN=−2w−1→(−2w−1)+2w=2w−1 比较-1和0U,-1被转化为UMAX,而0U不变,因此,-1大于0U。
