I am looking for a query to change a specific column value from 0 to 1.

Example:
I have a table column that is always numbered 0, 1, 2, 3, etc. I want to change it so it numbers 1, 2, 3, 4 etc

Thanks!

The syntax to set the value of the column to the value + 1 for every row is

update table1

set columnname = columnname + 1
0

Is there a syntax that will change the row value to 1........only if the value is 0?

I have existing table entries with the value of 1 which I don't want the value changed.
