Practice complex SQL queries-find second last record

-

Write a SQL query to fetch the second last record from employee table.

Table Name: EMPLOYEE

Approach: Using window function sort the data in descending order based on employee id. Provide a row number to each of the record and fetch the record having row number as 2.

Solution-1

select * from employees
where employee_id in(
select MAX(employee_id)-1 as employee_id from employees
);

— there is issue in this query, lets say employee_id 205 is not present then this query will fail

Solution-2
–PERFECT SOLUTION USING WINDOW FUNCTION WITHOUT PARTION BY
SELECT * FROM(
SELECT
ROW_NUMBER() OVER (ORDER BY EMPLOYEE_ID DESC) AS RN,
EMP.*
FROM employees EMP)
WHERE RN=2;

Complex SQL: fetch the users who logged in consecutively 3 or more times (lead perfect example)

-
From the login_details table, fetch the users who logged in consecutively 3 or more times. Table Name : LOGIN_DETAILS Approach : We need to fetch users who have appeared 3 or more times consecutively in login details table. There is a window function which can be used to fetch data from the following record. Use that window function to compare the user name in current row with user name in the next row and in the row following the next row. If it matches then fetch those records. –Table Structure: drop table login_details; create table login_details( login_id int primary key, user_name varchar(50) not null, login_date date); delete from login_details; insert into login_details values (101, ‘Michael’, current_date), (102, ‘James’, current_date), (103, ‘Stewart’, current_date+1), (104, ‘Stewart’, current_date+1), (105, ‘Stewart’, current_date+1), (106, ‘Michael’, current_date+2), (107, ‘Michael’, cur...
