Working with DATEFROMPARTS()
In this lesson, you also learned how to combine different parts of a date, which are in separate columns into one.
In the paper_shop_daily_sales table, the columns year_of_sale, month_of_sale, and day_of_sale, store the different values of a date.
| product_name | units | year_of_sale | month_of_sale | day_of_sale |
|--------------|-------|--------------|---------------|-------------|
| notebooks | 2 | 2019 | 1 | 1 |
| notebooks | 3 | 2019 | 5 | 12 |
| ... | ... | ... | ... | ... |
You need to combine all these columns into one, by using the DATEFROMPARTS() function.
