MySQL syntax for inserting a new row in middle rows?

mysql sintax for insert a new row in middle rows or wherever we want without updating the existing row, but automatically increment the primary key (id)?

' id | value
' 1  | 100
' 2  | 200
' 3  | 400
' 4  | 500

I want to insert a new row after id 2, with a value = 300. I want the output as below:

' id | value
' 1  | 100
' 2  | 200
' 3  | 300  <-- new row with id (automatic increment)
' 4  | 400  <-- id=id+1
' 5  | 500  <-- id=id+1 

Thanks.
