Question

I have this Code Where i am inserting some values in database. I am getting an Invalid Cursor State Exception. What may be the reason … I am first selecting some values from a table(Select statement) which i need to insert into another table. I am doing 2 insert operations over here..

<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
    pageEncoding="ISO-8859-1"%>

String id = request.getParameter("employeeidname");
int offshore = Integer.parseInt(request.getParameter("offshorename"));
String email = request.getParameter("emailidname");
String profile = request.getParameter("profilename");
String empname = request.getParameter("employeenamename");
String projectname = request.getParameter("projectname");


/* HandleConnections con = new HandleConnections(); */
Connection con=null;
try{
    String driver = "sun.jdbc.odbc.JdbcOdbcDriver";
Class.forName(driver);

String db = "jdbc:odbc:Practice_Database";
con = DriverManager.getConnection(db,"","");
ResultSet rs=null;
Statement st2 =con.createStatement();
Statement st3 =con.createStatement();
Statement st = con.createStatement();
String sql1="SELECT Project_ID FROM Project_Table WHERE Project_Name = '"+projectname+"'";
rs= st2.executeQuery(sql1);
String sql ="INSERT into Emp_Product_Project_Mapping(Emp_IDFK, Project_IDFK) values('"+id+"',"+rs.getInt("Project_ID")+")";
int j = st3.executeUpdate(sql);
/* conn = con.getConnection(); */

SendMail send = new SendMail();
Generator gen1 = new Generator();
String temp = gen1.gen(8);
send.sendmail("[e-mail]", email, temp);

String sql2= "INSERT into Employee_Table(Emp_ID,F_Name,Profile,Offshore,Email,Password) values('"+id+"','"+empname+"','"+profile+"',"+offshore+",'"+email+"','"+temp+"')";
int i = st.executeUpdate(sql2);
if(i==1)
out.println("Values inserted successfully");
}
catch(Exception e){
    System.out.print(e);
    e.printStackTrace();
    }

The URL from where i am getting the values is ::

http://localhost:8080/2_8_2012/jsp/Addemployeedatabase.jsp?employeeidname=A12&offshorename=2&emailidname=[e-mail]&profilename=GL&employeenamename=Mayur&projectname=INFRASTRUCTURE

Exception ::

[Microsoft][ODBC Driver Manager] Invalid cursor statejava.sql.SQLException: [Microsoft][ODBC Driver Manager] Invalid cursor state

Solved By using ::

while(rs.next) to retrieve values from result set...

If you literally want simultaneous independent statement execution then you want multiple connection objects, typically managed via a connection pool.

Beware though that not all drivers support multiple Statements per Connection, most notably the JDBC-ODBC bridge
