UPDATE Speed - Decrement Counter?
Posted by: dbv

The following is very fast:

UPDATE table set count=count+1 where key_column=constant

However, I want to decrement a value:

UPDATE table set count=count-1 where key_column=constant

But it doesn't update the row. Is there a way to update the row efficiently? Thanks.
