Question

What am I doing wrong? I keep getting weird errors from SQL?

   //get parameters from the request
 String custID=request.getParameter("cust_ID");
 String saleID=request.getParameter("sale_ID");
 String firstName=request.getParameter("first_Name");
 String mInitial=request.getParameter("mI");
 String lastName=request.getParameter("last_Name");
 String streetName=request.getParameter("street");
 String city=request.getParameter("city");
 String state=request.getParameter("state");
 String zipCode=request.getParameter("zip_Code");
 String DOB=request.getParameter("DOB");
 String agentID=request.getParameter("agent_ID");
 String homePhone=request.getParameter("home_Phone");
 String cellPhone=request.getParameter("cell_Phone");
 String profession=request.getParameter("profession");
 String employer=request.getParameter("emoployer");
 String referrer=request.getParameter("referrer");


   preparedStatement = conn.prepareStatement("INSERT INTO customer (cust_ID, sale_ID, first_Name, mI, last_Name, street_Name, city, state, zip_Code, DOB, agent_ID, home_Phone, cell_Phone, profession, employer, referrer)"
                + " VALUES (?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?)");

preparedStatement.setInt(1, Integer.valueOf(custID));
preparedStatement.setInt(2, Integer.valueOf(saleID));
preparedStatement.setString(3, firstName);
preparedStatement.setString(4, mInitial);
preparedStatement.setString(5, lastName);
preparedStatement.setString(6, streetName);
preparedStatement.setString(7, city);
preparedStatement.setString(8, state);
preparedStatement.setString(9, zipCode);
preparedStatement.setString(10, DOB);
preparedStatement.setInt(11, Integer.valueOf(agentID));
preparedStatement.setString(12, homePhone);
preparedStatement.setString(13, cellPhone);
preparedStatement.setString(14, profession);
preparedStatement.setString(15, employer);
preparedStatement.setString(16, referrer);

preparedStatement.executeUpdate();

You are tyring to insert a NULL value into the street_Name column which has a NOT NULL constraint.

Probably something is wrong here:

String streetName=request.getParameter("street");

Double check the name of the request parameter against the actual request. Maybe there is a mismatch in names or the requesting side forgets to send it.

BTW look like you have a typo here to:

String employer=request.getParameter("emoployer");

I expect your request parameter is called “employer” without the additional o
