Update Cursor not working

[JordanParfitt]

I have this update cursor. The code executes in LiClipse without an error at all but none of my rows update in SDE. Am I missing a step?

Thanks,
Jordan

        cursor.updateRow(row)
        
del cursor, row
        
print 'done'

Maybe an overly simplistic observation, but in:

 if str(row.getValue("STRUCTURE_ID")) == 'None':

Is the 'None' meant to be a string or should it just be None for NoData? The way you have it now the conditional will only trigger if there's actually the string 'None' in those cells.

All of my code is executing. It makes it pass that if statement and even if I remove the if statement it doesn't work either. The database just isn't being updated.

for row in cursor:
    row.STRUCTURE_ID = str(row.getValue("ENCLOSURE_ID"))
    cursor.updateRow(row)

Thank You
