Applying Multiple Window Functions in 1 SELECT using different partition
0
I was wondering if there is anything wrong with using this method.
I have a working demo of what i'm trying to do below
In the SELECT statement I have used 2 OVER clauses.
Is there any risk that the data could get out of sequence?
CREATE TABLE basic_pays (
employee_id int,
fiscal_year INT,
salary DECIMAL(10 , 2 ),
PRIMARY KEY (employee_id, fiscal_year)
);
INSERT INTO basic_pays(employee_id, fiscal_year,salary) VALUES(100,2017,24000);
INSERT INTO basic_pays(employee_id, fiscal_year,salary) VALUES(101,2017,17000);
INSERT INTO basic_pays(employee_id, fiscal_year,salary) VALUES(102,2017,18000);
INSERT INTO basic_pays(employee_id, fiscal_year,salary) VALUES(103,2017,9000);
INSERT INTO basic_pays(employee_id, fiscal_year,salary) VALUES(100,2018,25920);
INSERT INTO basic_pays(employee_id, fiscal_year,salary) VALUES(101,2018,18190);
INSERT INTO basic_pays(employee_id, fiscal_year,salary) VALUES(102,2018,18360);
INSERT INTO basic_pays(employee_id, fiscal_year,salary) VALUES(100,2020,26179.2);
INSERT INTO basic_pays(employee_id, fiscal_year,salary) VALUES(101,2020,19463.3);
INSERT INTO basic_pays(employee_id, fiscal_year,salary) VALUES(102,2020,19278);
INSERT INTO basic_pays(employee_id, fiscal_year,salary) VALUES(103,2020,10206);
SELECT
employee_id,
fiscal_year,
salary,
LAG(salary)
OVER (PARTITION BY employee_id ORDER BY fiscal_year) previous_salary,
SUM(salary) /SUM(SUM(salary))
OVER (PARTITION BY fiscal_year ORDER BY fiscal_year) salary_percentage
FROM
basic_pays
GROUP BY
employee_id, fiscal_year, salary
ORDER BY fiscal_year, employee_id
DROP TABLE basic_pays
