Question

I have a table named books with bookID, bookName, count , orderCount

i’d like to write an sql query that will update all books.orderCount to books.orderCount+1.

How shall i do that using executeQuery("UPDATE books...."); ?
I’m having troubles with the syntax.

I’ve tried to search info on the net however most articles are about INSERT or DELETE commands and the only article that was related suggested to retrieve orderCount to Java, update it and then write it back to SQL. if possible i prefer to avoid it as it may cause serious problems (Locks on records are not needed for this task so i can not use them to avoid problems)

Answer 1

this should be pretty straight forward,

UPDATE books 
SET orderCount = orderCount + 1
