TIMESTAMPDIFF是 MySQL 中的一个函数,用于计算两个日期或时间值之间的差异。当使用TIMESTAMPDIFF函数计算两个time类型的值时,如果第二个时间值早于第一个时间值,函数会返回负值。这是因为TIMESTAMPDIFF函数计算的是两个时间点之间的差值,而不是绝对值。
On 32-bit platforms, the supported range of values for this function is the same as for the TIMESTAMP type (see Section 13.2.1, “Date and Time Data Type Syntax”, for range information). On 64-bit platforms, beginning with MySQL 8.0.28, the maximum supported value is '3001-01-18 23...
MySQL 以YYYY-MM-DD hh:mm:ss格式检索和显示DATETIME值。 The supported range is'1000-01-01 00:00:00'to'9999-12-31 23:59:59'. 支持的范围是'1000-01-01 00:00:00'至'9999-12-31 23:59:59'。 TheTIMESTAMPdata type is used for values that contain both date and time parts.TIMESTAMPhas...
MySQL Time Type The MySQL time type is used to store time values without a date component. It can store values in the range of ‘-838:59:59’ to ‘838:59:59’. The time type has a precision of seconds, which means that it can store time values up to the second level. ...
