cmdb.Parameters.AddWithValue("@person", personNameTB.Text);

Answer 1

What you need is to use PreparedStatement in Java. With the example that you’ve, the corresponding PreparedStatement would look something like this:

PreparedStatement ps = connection.prepareStatement("insert into Assignment1(textname,person,date,text) values(?,?,?,?)");

You would then use the appropriate ps.setXX() methods to set the appropriate values for the parameters that you’ve defined and then call ps.executeUpdate() to execute the call to the database.

The “JDBC(TM) Database Access” would be a good place to start learning about how to use or execute common SQL statements, and perform other objectives common to database applications.
