Workaround for “null primitives” in JDBC PreparedStatement? [duplicate]

Answer 1

Don't use any of those and use setObject instead, let the JDBC driver to manage the null values instead of you.

Answer 2

You can use the setNull(int parameterIndex, int sqlType) method of the PreparedStatement class.

Here's an example of how to use it:

  String query = 
     "insert into nullable_table(id,string_column, int_column) values(?, ?, ?)";

  // create PrepareStatement object
  PreparedStatement pstmt = connection.prepareStatement(query);
  pstmt.setString(1, id);
  pstmt.setNull(2, java.sql.Types.VARCHAR);
  pstmt.setNull(3, java.sql.Types.INTEGER);

Example taken from here.

Answer 3

You need to use setNull() method. Based on parameter is null or not check you need to either call setNull() (or) setInt().
