QUESTION

Trouble with SQL query execution using JDBC. getting error with result set

Asked 2022-Feb-24 at 21:02

Im doing a webscaping project in Java and im having trouble with executing the SQL code to load the variables. im using IntelliJ with maven as the build.

I keep getting this error

java.sql.SQLException: Statement.executeQuery() cannot issue statements that do not produce result sets.
    at com.mysql.cj.jdbc.exceptions.SQLError.createSQLException(SQLError.java:129)
    at com.mysql.cj.jdbc.exceptions.SQLError.createSQLException(SQLError.java:97)
    at com.mysql.cj.jdbc.exceptions.SQLError.createSQLException(SQLError.java:89)
    at com.mysql.cj.jdbc.exceptions.SQLError.createSQLException(SQLError.java:63)
    at com.mysql.cj.jdbc.StatementImpl.executeQuery(StatementImpl.java:1135)
    at com.cst3511.website.scraper.Scarper.main(Scarper.java:54)

this is my code for the scraper class

public class Scarper {

    public static void main(String[] args) throws ClassNotFoundException, SQLException, IOException {

        final String url =
                "https://www.myshiptracking.com/ports-arrivals-departures/?mmsi=&pid=GB&type=0&time=&pp=50";

        try {

            Document doc = Jsoup.connect(url).get();
            Element table = doc.select(".cs-table").first();
            Elements rows = doc.select("div.table-row");


            for (Element row : rows) {

                String event = row.select("div.col:nth-of-type(2)").text();
                String time = row.select("div.col:nth-of-type(3)").text();
                String port = row.select("div.col:nth-of-type(4)").text();
                String vessel = row.select(".td_vesseltype.col").text();

            // connecting to SQL
            Class.forName("com.mysql.cj.jdbc.Driver");
            Connection conn = DriverManager.getConnection("jdbc:mysql://localhost:3306/oceana",
                        "user", "pass");
ResultSet rs;

                PreparedStatement stmt = conn.prepareStatement("INSERT INTO status_table(status, time, port , vessel) VALUES (?,?,?,?)");
                stmt.setString(1, event);
                stmt.setString(2, time);
                stmt.setString(3, port);
                stmt.setString(4, vessel);
                rs = stmt.executeQuery();
                if (rs.next()){
                    System.out.println(rs.getString(1)+""+ rs.getString(2)+" "+ rs.getString(3)+""+ rs.getString(4));
                }

            
            }

        } catch (ClassNotFoundException | SQLException | IOException e) {
            e.printStackTrace();
        }
    }
}

in my error it says line 54 which is

 rs = stmt.executeQuery();

I just dont know what im missing here... Appreciate any Geniuses out there to help.

ANSWER

executeQuery() is meant for fetch (SELECT) statements that return results.

INSERT (as well as UPDATE and DELETE) statements should use executeUpdate().
