-- 将时间转换为毫秒SET@current_time_in_milliseconds=UNIX_TIMESTAMP(current_time)*1000; 1. 2. 这段代码的含义是将存储在current_time变量中的时间戳转换为毫秒,并存储在@current_time_in_milliseconds变量中。 步骤五:输出结果 最后一步是输出结果,可以使用以下代码输出结果: -- 输出结果SELECT@current_time...
SELECT UNIX_TIMESTAMP(NOW()) * 1000 + MICROSECOND(NOW()) / 1000 AS current_time_in_milliseconds; 参考链接 MySQL 官方文档 - 时间函数 通过上述方法,你可以在 MySQL 中获取当前时间的毫秒数,并应用于各种需要高精度时间戳的场景。 相关搜索:mysql获取当前秒数linux获取当前时间秒数mysql获取当前毫秒数js获...
而要获取毫秒值,只需将其乘以1000。以下是实现这一功能的代码: # 使用 UNIX_TIMESTAMP() 函数获取当前时间的秒数cursor.execute("SELECT UNIX_TIMESTAMP(NOW()) * 1000")# 获取查询结果,即当前时间的毫秒值current_time_milliseconds=cursor.fetchone()[0]print(f"当前时间的毫秒值是:{current_time_millisecond...
MySQL中的时间戳(Timestamp)是指自1970年1月1日(UTC)以来的秒数。而毫秒级别的时间戳则是指自1970年1月1日(UTC)以来的毫秒数。 获取当前时间戳毫秒的方法 在MySQL中,可以使用NOW()函数获取当前的日期和时间,然后使用UNIX_TIMESTAMP()函数将其转换为秒级别的时间戳,再乘以1000并加上微秒部分(使用MICROSECOND(...

因最近国际去Oracle上MySQL,这就不可避免的涉及到时区和timestamp问题。做一下实验,总结一下。 Oracle 首先看下oracle concepts对timestamp的定义: The TIMESTAMP data type is an extension of theDATEdata type. It stores fractional seconds in addition to the information stored in theDATEdata type. TheTIME...
