How to update data in Oracle database?

To update data in an Oracle database, you can use the SQL UPDATE statement. This statement allows you to modify existing records in a table based on specified conditions.

Syntax:

UPDATE table_name
SET column1 = value1, column2 = value2, ...
WHERE condition;

Explanation:

• UPDATE table_name: Specifies the table you want to update.
• SET column1 = value1, column2 = value2, ...: Defines the new values for the columns you want to update.
• WHERE condition: Determines which records should be updated. Without a WHERE clause, all records in the table will be updated.

Example:

Suppose you have a table named employees with columns employee_id, first_name, last_name, and salary. If you want to update the salary of an employee with employee_id 101 to $60,000, you would use the following SQL statement:

UPDATE employees
SET salary = 60000
WHERE employee_id = 101;
