It's my understanding that you are looking to work with ISO weeks in Denodo and encountered an issue with the code using the "GETWEEK" function.
The "GETWEEK" function in Denodo follows the ISO standard and directly returns the day of the week as an integer. Therefore, you can use the function as follows:
GETWEEK(ADDWEEK(CURRENT_DATE(), 1))
This code will work without the need for the first argument "ISO_WEEK."
For more detailed information about the "GETWEEK" function and its usage, you can visit this link on the Denodo Community: GETWEEK Function in Denodo.
Hope it helps
