| **DATEADD** | `DATEADD(DATE_COL, 1, 'day')` | `DATEADD(date, 1, 'day')` | Supposing the DATE_COL is 2022-03-14. The result is 2022-03-15. |
| | `DATEADD(DATE_TIME_COL, 2, 'month')` | `DATEADD(datetime, 2, 'month')` | Supposing the DATE_COL is 2022-03-14 03:14. The result is 2022-05-14 03:14. |
| | `IF(NOW() < DATE_COL, "true", "false")` | `IF(NOW() < date, "true", "false")` | If current date is less than DATE_COL, it returns true. Otherwise, it returns false. |
| | `IF(NOW() < DATEADD(DATE_COL,10,'day'), "true", "false")` | `IF(NOW() < DATEADD(date,10,'day'), "true", "false")` | If the current date is less than DATE_COL plus 10 days, it returns true. Otherwise, it returns false. |
