Question

I’m using access 2007, I have almost 40 columns in a table and i want to reset all data to null except for one column. I am looking for the proper query like this

Delete table.* from table except one column

Anyone knows how to do this?

Answer 1

You could use UPDATE.

UPDATE table
SET
  col1 = null,
  col2 = null,
  col4 = null,
  ....
WHERE 1=1

This will leave all the data in col3 intact.
