Question
INSERT INTO Employees (ID, Name, Age, Department)VALUES (1, 'John Doe', 30, 'HR'), (2, 'Jane Smith', 28, 'Finance'), (3, 'Michael Johnson', 35, 'IT'), (4, 'Emily Williams', 32, 'Sales'), (5, 'Robert Brown', 27, 'Marketing');SELECT Name, Age FROM Employees ORDER BY Age ASC LIMIT 1;SELECT MIN(Age), Name FROM Employees;SELECT LAST(Name), Age FROM Employees ORDER BY Age DESC;SELECT Name, Age FROM Employees WHERE Age = MIN(Age);
Solution
The above statements are written in SQL (Structured Query Language), which is used to manage and manipulate databases. Here's a step-by-step explanation of each statement:
INSERT INTO Employees (ID, Name, Age, Department)VALUES (1, 'John Doe', 30, 'HR'), (2, 'Jane Smith', 28, 'Finance'), (3, 'Michael Johnson', 35, 'IT'), (4, 'Emily Williams', 32, 'Sales'), (5, 'Robert Brown', 27, 'Marketing');
This statement is inserting five rows of data into the 'Employees' table. Each row includes an ID, Name, Age, and Department for each employee.
SELECT Name, Age FROM Employees ORDER BY Age ASC LIMIT 1;
This statement is selecting the Name and Age of the employee who is the youngest (has the lowest age). 'ORDER BY Age ASC' sorts the employees in ascending order by age, and 'LIMIT 1' returns only the first row of this sorted list.
SELECT MIN(Age), Name FROM Employees;
This statement is trying to select the Name of the employee with the minimum age. However, this statement will not work as expected because it will return the minimum age and the name of the first row, not necessarily the name of the employee with the minimum age.
SELECT LAST(Name), Age FROM Employees ORDER BY Age DESC;
This statement is trying to select the Name and Age of the oldest employee. However, the 'LAST' function does not exist in SQL. Instead, you should use 'ORDER BY Age DESC' to sort employees in descending order by age and 'LIMIT 1' to return only the first row.
SELECT Name, Age FROM Employees WHERE Age = MIN(Age);
This statement is trying to select the Name and Age of the employee(s) with the minimum age. However, this statement will not work because you cannot use the 'MIN' function in the 'WHERE' clause. Instead, you should use a subquery to first find the minimum age and then use this value in the 'WHERE' clause.
