When you do an INSERT you must supply values. For example

INSERT INTO mytable (fld1, fld2, fld3)
       VALUES(fldvalue1, fldvalue2, fldvalue3)

You must supply data for all NOT NULL fields. I suspect what you are trying to do is an UPDATE which would look like

UPDATE mytable
   SET fld1 = fld1value, fld2 = fld2value
 WHERE fld3 = fld3value

when is not an sql keyword used with t-sql insert.
The only reference to insert & when is pl/sql and then the syntax is "insert when"
