CREATE TABLE program (Program_ID INT, Name TEXT, Origin TEXT, Launch FLOAT, Owner TEXT)
CREATE TABLE broadcast (Channel_ID INT, Program_ID INT, Time_of_day TEXT)
CREATE TABLE broadcast_share (Channel_ID INT, Program_ID INT, Date TEXT, Share_in_percent FLOAT)
CREATE TABLE channel (Channel_ID INT, Name TEXT, Owner TEXT, Share_in_percent FLOAT, Rating_in_percent FLOAT)

Show me a bar chart for what is the total rating of channel for each channel owner?, and display in ascending by the X.
SELECT Owner, SUM(Rating_in_percent) FROM channel GROUP BY Owner ORDER BY Owner
SELECT "Owner", SUM("Rating_in_percent") FROM "channel" GROUP BY "Owner" ORDER BY "Owner" NULLS FIRST
