UPDATE in Snap is just the same as 'INSERT'

Mar 5, 2008 at 5:38 AM
We've found that the function of 'UPDATE' in Snap is not update fundamentally. UPDATE here is just the same as the function of 'INSERT',which in SQL means add new records .In our eyes,UPDATE means change the previous record or data to the current data,which is changed more or less based on the previous,not add new report,just coverage the previous.UPDATE here is not the function we expect.Now we urgently need the function of UPDATE in our eyes.

How to solve the problem?
