I am using aggregate functions to perform calculations on a page on our site. I need to have a drop down of various years to help filter out the specific data used in the aggregation codes. Is there a way for the aggregate filters to search and group the date / time field entries in a database for the calculations based on the year only and not have to enter the whole date / time format (mm/dd/yyyy 0:00:00)? When looking at the wix guide giving various details, the examples they use all involve the year being in its own column. Or, is there a way to use hooks or front end code to separate the year from the whole date time entry once a form is submitted to the database and have the year placed into its own column within the database which can then be used for the aggregate filter?
