Quick solution:

Note:
At the end of this article you can find database preparation SQL queries.
In this example, we will update department_id and salary value of the first three users from the users table.
Query
xxxxxxxxxx1
UPDATE "users"2
SET "department_id" = 5, "salary" = 60003
WHERE "id" <= 3;or
xxxxxxxxxx1
UPDATE "users"SET "department_id" = 5, "salary" = 6000 WHERE "id" = 1;2
UPDATE "users"SET "department_id" = 5, "salary" = 6000 WHERE "id" = 2;3
UPDATE "users"SET "department_id" = 5, "salary" = 6000 WHERE "id" = 3;Result:
create_tables.sql file:
