CAST函数:将一个表达式转换为指定的类型。 CONVERT函数:将一个表达式转换为指定的类型。 下面是使用以上两个函数将字符串转换为整数的示例代码: -- 使用CAST函数转换字符串为整数SELECTCAST('100'ASUNSIGNED)ASinteger_value;-- 使用CONVERT函数转换字符串为整数SELECTCONVERT('200',UNSIGNED)ASinteger_value; 1. 2....
If you are using a string in an arithmetic operation, this is converted to a floating-point number. If you convert a “zero” date string to a date, CONVERT() and CAST() return NULL when the NO_ZERO_DATE SQL mode is enabled. As of MySQL 5.0.4, they also produce a warning. 有关...
