hive FROM_UNIXTIME

Hive provides the `FROM_UNIXTIME` function to convert a UNIX timestamp (in seconds) to a string representing the corresponding date and time. The syntax for using `FROM_UNIXTIME` in Hive is as follows:

SELECT FROM_UNIXTIME(unix_timestamp) AS formatted_date
FROM your_table;

Here, `unix_timestamp` is the column or expression representing the UNIX timestamp you want to convert. `formatted_date` is an optional alias for the resulting formatted date string.

For example, if you have a table named `your_table` with a column `timestamp_col` containing UNIX timestamps, you can use the following query to convert them to formatted dates:

SELECT FROM_UNIXTIME(timestamp_col) AS formatted_date
FROM your_table;

This will return a result set with the formatted dates corresponding to the UNIX timestamps.
