MySQL: How to copy rows, but change a few fields?

I have a large number of rows that I would like to copy, but I need to change one field.

I can select the rows that I want to copy:

select * from Table where Event_ID = "120"

Now I want to copy all those rows and create new rows while setting the Event_ID to 155. How can I accomplish this?


          ( Event_ID
          , col2
     SELECT "155"
          , col2
      FROM Table WHERE Event_ID = "120"

Here, the col2, … represent the remaining columns (the ones other than Event_ID) in your table.
