I need to be able to modify single-select query input control. I explain myself: I need to add to the list of values that gives back the SQL query a static "added by hand" value. In example: If the SQL query returns these values['1', '2', '3', ...], I need to be able to add at the beginning of those values the value '0' or any other arbitrary value, that I want. Then, when the user executes the report, in the list of possible values that will be able to select, they will also appear the values that I have added in addition of whom the SQL query returns. Is possible to do that? where do i must to do the changes, to be able to do that? Some one can help me, or tell me where to start probing? Thanks a lot ;)
