Mastering MySQL TIME Data TypeSummary: in this tutorial, we will introduce you to the MySQL TIME data type and show you useful temporal functions to manipulate time data effectively. Introduction to MySQL TIME data type# MySQL uses the 'HH:MM:SS' format for querying and displaying a time ...
MySQL 8.0 does not support the 2-digitYEAR(2)data type permitted in older versions of MySQL. For instructions on converting to 4-digitYEAR, see2-Digit YEAR(2) Limitations and Migrating to 4-Digit YEAR, inMySQL 5.7 Reference Manual.
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...
The DATETIME type is used for values that contain both date and time parts. MySQL retrieves and displays DATETIME values in YYYY-MM-DD hh:mm:ssformat. The supported range is '1000-01-01 00:00:00' to '99...
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...

由于MYSQL官方文档已经很清晰 直接附上原始文档Date and Time Type Overview这里只分析需要注意的点: DATE 表示范围在'1000-01-01'to'9999-12-31' 存储格式为'yyyy-mm-dd',也可能出现年使用 two-digit表示 例如: 12-01-01 MYSQL解释规则为:00-69解释为2000-206970-99解释为1970-1999 ...
