Swap Salary - Leetcode Solution

The Swap Salary problem on Leetcode is as follows:

Given a table salary, update all salary to the id who has the minimum salary.

Here is the solution for the Swap Salary problem on Leetcode:

Step 1: First, let's write the initial SQL query to display the salary table:

SELECT * FROM salary;

This will display the table with all the columns such as id, name, and salary.

Step 2: Next, we want to update the salary column for all the id's equal to the minimum salary. We can use the following query to achieve this:

UPDATE salary 
SET salary = (SELECT MIN(salary) FROM salary)
WHERE salary = (SELECT MIN(salary) FROM salary);

This query finds the minimum salary from the table and updates all salary values where the salary is equal to the minimum salary.

Step 3: Finally, we can run the SELECT statement again to verify that the salary column has been updated:

SELECT * FROM salary;

This SQL query will display the updated salary table with the salary column updated for all id's matching the minimum salary.

And that is the solution for the Swap Salary problem on Leetcode.
