How can you change a table column name in Oracle?

To change the name of a table column, you can use the ALTER TABLE statement. Here is an example:

ALTER TABLE table_name RENAME COLUMN old_column_name TO new_column_name;

In this example, replace table_name with the name of the table where the field is to be modified, old_column_name with the field name to be changed, and new_column_name with the new field name.
