Updating Multiple Columns Using the UPDATE Statement

To update multiple columns in an Oracle table, you can use the following syntax:

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

In this syntax, table_name is the name of the table you want to update, column1 and column2 are the columns you want to update, value1 and value2 are the new values you want to set for each column, and condition is the condition that specifies which rows should be updated.

For example, if you wanted to update the first_name and last_name columns in the employees table to set the first name to ‘John’ and the last name to ‘Doe’ for all employees with an employee_id greater than 100, you would use the following query:

UPDATE employees SET first_name = 'John', last_name = 'Doe' WHERE employee_id > 100;

By using the UPDATE statement with the SET clause, you can efficiently update multiple columns in an Oracle table in a single query.

Conclusion

Updating multiple columns in an Oracle table is a common operation that can be easily accomplished using the UPDATE statement with the SET clause. By specifying the columns you want to update and the new values for each column, you can efficiently update multiple columns in a single query. This can save time and streamline your database operations, making it a valuable feature to have in your Oracle toolkit.
