hive datediff()

Hive's `datediff()` function calculates the number of days between two given dates. It takes two arguments, the end date and the start date, and returns the difference in days.
Here's an example usage of `datediff()` in Hive:
```sql
SELECT datediff('2022-01-01', '2021-01-01') AS days_diff;
```
In this example, `datediff()` calculates the number of days between January 1, 2022, and January 1, 2021. The result will be 365 days.
Please note that the `datediff()` function in Hive considers only the date portion of the input and ignores the time portion.

hive datediff
在Hive中,datediff函数用于计算两个日期之间的天数差。它的语法是datediff(date1, date2),其中date1和date2是以字符串形式表示的日期,可以是以下两种格式之一:yyyy-MM-dd HH:mm:ss或yyyy-MM-dd。该函数返回date1和date2之间的天数差,如果date1早于date2,则结果为负数。例如,如果我们执行select datediff('2019-06-25','2019-06-20'),将返回5,而执行select datediff('2019-06-25','2019-06-27'),将返回-2。\[1\]\[2\]\[3\]

hive datediff函数
hive的datediff函数用于计算两个日期之间的天数差异。具体而言,该函数返回开始日期减去结束日期的天数。如果开始日期晚于结束日期,则返回正值;如果开始日期早于结束日期,则返回负值。使用示例如下:datediff('开始日期','结束日期')。
示例代码:
```sql
SELECT datediff('2022-08-14', '2022-08-04');
```
该代码将返回开始日期和结束日期之间的天数差异。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
