posted 17 years ago
Hi!
I am using MS-access as backend and jdbc connection for transfering data from a servlet.But it gives an error saying that:SQL Exception, no resultset was created.
The Select ,Create table statement were executed successful.
Only the Insert statement is not executing correctly.

The insert statement won't create a ResultSet. What is the actual error?

Hi! Thanks for answering
Well here is the code bit ,:-
String str="create table student(stid Number,stname Number)";
res=stm.executeQuery(str);
PreparedStatement pstm=con.prepareStatement("INSERT INTO student (stid,stname) VALUES (?,?)");
pstm.setInt(1,9);
pstm.setInt(2,6);
pstm.executeUpdate();
ResultSet res1=stm.executeQuery("SELECT stid,stname FROM student");
out.println("<html>");
...
...
The error is :-
SQLException caught : No ResultSet was produced .
When i check the ms-access database,the table gets created
but the "Insert" statement does not execute.
ie.
Thanks

Okay, this topic is about 4 years old, but I'm going to answer it anyway.
The reason the executeQuery() is not producing a result set is because you're making an update, not pulling information with a query.
you should use the executeUpdate() method with your update when you are creating a table or inserting data. The executeUpdate() method returns an int, I think, being the status of the update.
That should update the DB. You don't even need to return anything if you don't want to. There will not be a result set.
