time_diff函数接受两个时间参数,并返回它们之间的差值。 -- 计算时间差SELECTtime_diff(end_time,start_time)AStime_differenceFROMtable_name; 1. 2. 3. 在上述代码中,end_time和start_time是两个时间字段,time_difference是计算得到的时间差。 3.3 输出结果 最后,我们可以将计算得到的时间差输出到一个结果表...
INSERTINTOresult_tableSELECT*,datediff(end_date,start_date)AStime_differenceFROMoriginal_table; 1. 2. 3. 4. 这里,result_table是结果表的名称,original_table是原始表的名称,end_date和start_date是时间字段的列名,time_difference是时间差的列名。 根据实际需求,选择合适的输出方法,并在 Hive 中执行相应的 ...
Otherwise the UDF calculates the fractional portion of the result based on a 31-day month and considers the difference in time components date1 and date2.date1 and date2 type can be date, timestamp or string in the format 'yyyy-MM-dd' or 'yyyy-MM-dd HH:mm:ss'. The result is ...
将日期字符串转换为日期类型并进行计算。可以使用FROM_UNIXTIME和UNIX_TIMESTAMP函数实现：将UNIX时间戳转换为日期字符串并计算两个日期之间的天数差值。假设有两个日期字符串 '2023-07-01' 和 '2023-07-19'：SELECT UNIX_TIMESTAMP('2023-07-19') - UNIX_TIMESTAMP('2023-07-01') AS days_difference; --...
unix_timestamp(end_time) - unix_timestamp(start_time)datediff 只能精确到天
