How can we change the field name in Oracle?

In Oracle database, you can use the ALTER TABLE statement to change the name of a table’s column. Below are the steps to change the column name.

1. Change the table’s field names using the ALTER TABLE statement. The syntax is as follows:

ALTER TABLE table_name RENAME COLUMN old_column_name TO new_column_name;

1. Replace “table_name” in the statement above with the table name where you want to change the field, replace “old_column_name” with the original name of the field you want to change, and replace “new_column_name” with the new name of the field you want to change.
2. Execute an ALTER TABLE statement to change the field name. For example, to rename the field “name” in the table “users” to “full_name”, you can execute the following statement:

ALTER TABLE users RENAME COLUMN name TO full_name;

After executing the above statement, the field “name” in the table “users” will be renamed to “full_name”. Please note that changing the field name may cause some stored procedures, triggers, or views that depend on that field to become invalid, so make sure to backup the database before changing the field name.
