Hive String to Date: TO_DATE Function Guide

To convert a string to a date, you can use the built-in function TO_DATE in Hive. For example, suppose there is a string column called date_string that contains date data, you can use the following statement to convert it to a date type:

SELECT TO_DATE(date_string) AS date
FROM table_name;

Please ensure that the format of the `date_string` is in line with the default date format in Hive to avoid any conversion errors. If the date string is not in the default Hive format, you can use other date conversion functions such as `FROM_UNIXTIME` or `UNIX_TIMESTAMP` for conversion.
