SQL Bulk Update: Change Field Values Fast

If you want to update the values of a specific field in bulk, you can use the UPDATE statement in SQL along with the WHERE clause to select the records to update. Here is an example:

Assuming there is a table named “employee” with a field called “department” that needs to be updated in bulk to “Sales,” you can use the following SQL statement:

UPDATE employee
SET department = 'Sales'
WHERE department <> 'Sales';

The statement above updates the department field of records in the employee table where the department is not equal to Sales to Sales.

Additional conditions can be added in the WHERE clause to update more specific records. For example:

UPDATE employee
SET department = 'Sales'
WHERE department <> 'Sales' AND hire_date < '2021-01-01';

Update the department field in the employee table to Sales for records where the department field is not Sales and the hire date is before 2021-01-01.
