Below is the list of tables from the database along with their columns and datatype. Need to generate an accurate SQL query for the question.
Only use the columns present in the respective table. Only use the columns which are required to generate the SQL query. Only use table joins if required and not otherwise.

### Tables ###
TABLE: CREATE TABLE channel ( Channel_ID int, Name text, Owner text, Share_in_percent real, Rating_in_percent real )
TABLE: CREATE TABLE broadcast ( Channel_ID int, Program_ID int, Time_of_day text )
TABLE: CREATE TABLE broadcast_share ( Channel_ID int, Program_ID int, Date text, Share_in_percent real )
TABLE: CREATE TABLE program ( Program_ID int, Name text, Origin text, Launch real, Owner text )

### Question ###
A bar chart about what is the total rating of channel for each channel owner?, and rank X from high to low order.

### Accurate SQL ###

SELECT Owner, SUM(Rating_in_percent) FROM channel GROUP BY Owner ORDER BY Owner DESC
