Oracle SQL syntax

问题

This is my table structure . I have many problems in trying to make different things work .

1. How do I enter the values into task where Monday = 62 ?

   INSERT INTO it_time_track (task,percentage)
   VALUES ('Support',null) where Monday=62; commit ;
   

This gives me an error

-- I fixed it by making it an interactive Grid on Oracle Apex and doing a select to display this table and then I went on to edit it manually .

回答1:

UPDATE it_time_track 
SET Monday = (SELECT SUM(Monday)  
                  FROM it_time_track 
                  ) 
WHERE Id = 7
