PreparedStatement setNull(..)

Question

Java PreparedStatement provides a possibility to explicitely set a Null value. This possibility is:

prepStmt.setNull(parameterIndex, Types.VARCHAR);
<         


        

Answer 1

Finally I did a small test and while I was programming it it came to my mind, that without the setNull(..) method there would be no way to set null values for the Java primitives. For Objects both ways

setNull(..)

and

set(.., null)) 

behave the same way.
