当我尝试o插入数据时dataexecuteQuery（）无法正常工作吗？

Question

Can't seem to fix this. Been trying to get it to work for the past hour. any help would be appreciated.

INFO: Server startup in 868 ms
java.sql.SQLException: Can not issue data manipulation statements with executeQuery().Event{id=0, name='dads', venue='dasd', startDate='11/11/11', endDate='12/11/11'}

Seemed to be getting an error when I try to do an insert.

public void addEvent(Event event) throws DaoException{
        Connection con = null;
        PreparedStatement ps = null;
        ResultSet rs = null;
        try {
            con = this.getConnection();

            String query = "INSERT INTO TABLE EVENT VALUES(null, ?, ?, ?, ?)";         
            ps = con.prepareStatement(query);
            ps.setString(1, event.getName());
            ps.setString(2, event.getVenue());
            ps.setString(3, event.getStartDate());
            ps.setString(4, event.getEndDate());

            rs = ps.executeQuery();
        }catch(SQLException e) {
            System.out.println(event.toString());
            e.printStackTrace();
        }finally {
            try {
                if (rs != null) {
                    rs.close();
                }
                if (ps != null) {
                    ps.close();
                }
                if (con != null) {
                    freeConnection(con);
                }
            } catch (SQLException e) {
                throw new DaoException("Couldn't " + e.getMessage());
            }
        }
    }

Answer 1

for inserting or updating or deleting you should use executeUpdate ()

executeUpdate() returns int value

so replace this line rs = ps.executeQuery(); with

int result = ps.executeUpdate();

Note you will get another error after modifying as per above because you sql query is also wrong

Use the following query

INSERT INTO EVENT VALUES(null, ?, ?, ?, ?)

Answer 2

it looks like incorrect syntax of INSERT Query, update it likewise

INSERT INTO EVENT VALUES(null, ?, ?, ?, ?) // remove TABLE word
//INSERT INTO TABLE_NAME VALUES(...) , this is correct syntax.

also correct here too

    executeUpdate() instead of executeQuery()
// for insert/update/delete query always use executeUpdate(),
// for select query use executeQuery()
