CREATE TABLE Services (Service_ID NUMBER, Service_Type_Code CHAR)
CREATE TABLE Events (Event_ID NUMBER, Service_ID NUMBER, Event_Details VARCHAR2)
CREATE TABLE Participants_in_Events (Event_ID NUMBER, Participant_ID NUMBER)
CREATE TABLE Participants (Participant_ID NUMBER, Participant_Type_Code CHAR, Participant_Details VARCHAR2)

Give me a bar chart, that just lists the participant ids as Y and their details as X-axis, and rank by the Participant_ID in descending.
SELECT Participant_Details, Participant_ID FROM Participants ORDER BY Participant_ID DESC
SELECT "Participant_Details", "Participant_ID" FROM "Participants" ORDER BY "Participant_ID" DESC
