1、错误描述
java.sql.SQLException: Can not issue data manipulation statements with executeQuery().at com.mysql.jdbc.SQLError.createSQLException(SQLError.java:996)at com.mysql.jdbc.SQLError.createSQLException(SQLError.java:935)at com.mysql.jdbc.SQLError.createSQLException(SQLError.java:924)at com.mysql.jdbc.SQLError.createSQLException(SQLError.java:870)at com.mysql.jdbc.StatementImpl.checkForDml(StatementImpl.java:472)at com.mysql.jdbc.StatementImpl.executeQuery(StatementImpl.java:1401)at com.you.sql.Student.commonMethod(Student.java:117)at com.you.sql.Student.insertStudent(Student.java:86)at com.you.sql.Student.main(Student.java:181)2、错误原因
public static void insertStudent(){StringBuffer sql = new StringBuffer();int j = 0;String str = "0";for(int i=5;i<1000;i++){++j;if(i%2 == 0){str = "0";}else{str = "1";}sql.append("insert into t_stu_info (").append(i).append(",").append(103+j+"").append(",").append("zhangsan"+(i-4)).append(",").append(str).append(",").append(Integer.parseInt(Math.round(Math.random()*10+20)+"")).append(",").append("123"+i);}commonMethod(sql.toString());}/** * * @Title:Student * @Description: * @param sqlStu * @Date:2015年6月11日 上午12:25:56 * @return :void * @throws */public static void commonMethod(String sqlStu){StringBuffer sql = new StringBuffer();sql.append(sqlStu);Connection conn = null;Statement stat = null;ResultSet rs = null;try {try{Class.forName(DRIVER_CLASS);}catch (ClassNotFoundException e){e.printStackTrace();}conn = DriverManager.getConnection(URL, USER, PASSWORD);stat = conn.createStatement();rs = stat.executeQuery(sql.toString());while(rs.next()){String stuId = rs.getString("stu_id");String stuName = rs.getString("stu_name");String stuSex = rs.getString("sex");String stuAge = rs.getString("stu_age");String stuPhone = rs.getString("stu_phone");System.out.println("学号："+stuId+"—-"+"姓名："+stuName+"—-"+"性别："+stuSex+"—"+"年龄："+stuAge+"—-"+"电话："+stuPhone);}} catch (SQLException e) {e.printStackTrace();}finally{if(rs != null){try{rs.close();}catch (SQLException e){e.printStackTrace();}}if(stat != null){try{stat.close();}catch (SQLException e){e.printStackTrace();}}if(conn != null){try{conn.close();}catch (SQLException e){e.printStackTrace();}}}}3、解决办法
由于在执行插入操作时，调用了executeQuery方法，出现错误；插入操作应该调用executeUpdate方法
int result = stat.executeUpdate(sql.toString());
，如果我们想要更多的玫瑰花，就必须种植更多的玫瑰树。
