Using created attribute values for indicators
I'm trying to create an indicator that shows the food production of each function with the attribute "food production/m2". I created a new attribute called FOOD_PRODUCTION in the Function value table and I set the values for the corresponding functions such as vegetable gardens or corn fields. My intended following steps on the excel sheet were:
- Getting the names of functions with the attribute FOOD_PRODUCTION
- Getting the attribute value for each retrieved function
- Getting the lotsize of each retrieved function
For the step 1, I used the query:
i also tried:
In the query tool, the conditions are not considered, since it retrieves the name of functions that don't fit the conditions. And when I update the excel, it is marked as an invalid query.
For testing purposes, I tried the query "SELECTNAMEWHERE_FUNCTION_IS_X" and it neither worked.
Besides, I didn't find the query to retrieve an attribue value for a specific function.
I guess I'm doing something wrong. May you please guide me through this?
Thank you very much.
