What is the SQL statement for modifying a column name in Hive?

To rename a field in a Hive table, you can use the ALTER TABLE statement with the RENAME COLUMN clause. Here is an example of the SQL statement to modify a field name:

ALTER TABLE table_name CHANGE column_name new_column_name column_data_type;

table_name refers to the name of the table being modified, column_name refers to the name of the field being modified, new_column_name is the new field name, and column_data_type is the data type of the field.

For example, to change the field name from old_column to new_column in a table, you can use the following SQL statement:

ALTER TABLE my_table CHANGE old_column new_column int;

This will change the field name from old_column to new_column and set the data type to integer.
