How to Update Hive Table Data
To update the data in the fields of a Hive table, you can use the UPDATE statement in Hive. Below is an example of updating field data:
UPDATE table_name
SET column_name = new_value
WHERE condition;
In this example, `table_name` is the name of the table to be updated, `column_name` is the name of the field to be updated, `new_value` is the new value to update with, and `condition` is the condition for the update.
Please note that the support for UPDATE statements is limited in Hive. It is generally recommended to use INSERT OVERWRITE statements to overwrite data in tables in Hive. If updating data is necessary, you can create a temporary table, insert the updated data into the temporary table, and then overwrite the original table with the data from the temporary table.
