Hi Experts,

    When I do an update on the table I need to automatically increment one of the fields something like so:

UPDATE MyTable
SET
        Value1 = 'NewValue'
        Value2 = Value2 + 1


Is there a way to do this somehow?

Value2 is used kind of like a version number!  Don't ask!

Thanks!

you can write a update query as you mentioned

UPDATE MyTable
SET
        Value1 = 'NewValue'
        Value2 = Value2 + 1


or another way can be to write a trigger...

You can do just as you posted,

UPDATE MyTable
SET
        Value2 = Value2 + 1

The problem you may be getting is your syntax, you're missing a comma, just before 'Value2 =':

UPDATE MyTable
SET
        Value1 = 'NewValue',
        Value2 = Value2 + 1

I assume you have a where clause that will filter only those rows you wish to update.
