I need to take 3 fields from a query as columns(name, lastname ,id) and then the other columns to be all the days of the month. So, each row will show a person (name, lastname, id) and i can select with combobox what he did each day.
Sounds like you are trying to create a field for each day of the month. [31 date fields?] Which would go against the rules of normalizing a db. Just one date field to store the date of the action.
