Hello,

So i want to use the INSERT OR UPDATE command so i can update a COUNTER for a given name:

INSERT OR UPDATE myTable
SET name='Omer',  counter = counter + 1;

as you can see with the above code - if the row is non-existent then we get an error because COUNTER is NULL! 
I tried the following to fix this but all have failed:

INSERT OR UPDATE myTable
SET name = 'Omer', 
    counter = CASE 
        WHEN counter IS NULL THEN 1 
        ELSE counter + 1
    END

INSERT OR UPDATE myTable SET name='Omer',counter = COALESCE(counter + 1, 1)

 

INSERT OR UPDATE myTable SET name='Omer',counter = IFNULL(counter + 1, 1)

For any of the solutions above i received the error:
