Create a MySQL Stored Procedure to Modify Employee Salary

Create a Stored Procedure to Update Employee Salary

Write a MySQL query to create a stored procedure that updates an employee's salary.

Solution:

-- Change the delimiter to allow multi-line stored procedure definition
DELIMITER //

-- Create a stored procedure named `UpdateEmployeeSalary`
CREATE PROCEDURE UpdateEmployeeSalary(
    IN p_EmployeeID INT,          -- Input parameter: Employee ID
    IN p_NewSalary DECIMAL(10,2)  -- Input parameter: New salary amount
)
BEGIN
    -- Update the salary of the employee with the given EmployeeID
    UPDATE Employees 
    SET Salary = p_NewSalary 
    WHERE EmployeeID = p_EmployeeID;
END //

-- Reset the delimiter back to `;`
DELIMITER ;
