SQLIite - update two columns

Question

Hi, how can I update 2 columns at a time?

I tried the following statement, which doesn't work:

UPDATE exercises
SET times_answered = times_answered + 1
AND av_answeringTime = av_answeringTime + ( (av_answeringTime / (times_answered) ) + ?) * (times_answered + 1)
WHERE name = ?

Thanks.

Answer 1

Use a comma instead of your "AND":

UPDATE exercises
SET times_answered = times_answered + 1,
    av_answeringTime = av_answeringTime + ( (av_answeringTime / (times_answered) ) + ?) * (times_answered + 1)
WHERE name = ?

Answer 2

Try something like this...

UPDATE exercises
SET times_answered = times_answered + 1,
av_answeringTime = av_answeringTime + ( (av_answeringTime / (times_answered) ) + ?) * (times_answered + 1)
WHERE name = ?

Answer 3

The SQL UPDATE syntax is:

UPDATE table SET
  column1 = value1,
  column2 = value2
WHERE condition

Instead of the AND you need a comma
