SQL UPDATE: Edit Database Data Tutorial

To modify data in the database, you need to use the UPDATE statement. Here is an example:

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

In this example, you need to replace “table_name” with the name of the table to be updated, replace “column1” and “column2” with the names of the columns to be updated, replace “value1” and “value2” with the values to be updated, and replace “condition” with the criteria for specifying the rows to be updated.

For example, if you want to update all the “John” values in the “name” column of the table to “Jane”, you can use the following statement:

UPDATE employees
SET name = 'Jane'
WHERE name = 'John';

Please ensure to backup your database before executing the UPDATE statement to prevent any unexpected issues.
