RE: InstantDB: insert detection


Arno,

It does say in the documentation that:

"...if you use a results set to update an underlying table, you will not see
that change refelected in the results set itself. However, as soon as you
query the table again, any updated values will become visible in the new
results set."

Subject: InstantDB: insert detection


Hi,

I was trying to insert a row into a resultset and read this row immediatly,
without querying the DB again. Is this supposed to work in instantDB? See
the code below.

As you might see in the code example below, I am trying to get the id-value
of a table where the id-column is marked as AUTO INCREMENT. Is there a smart
way to do this?


Connection con = Transact.getConnection ();
Statement stmt = con.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE,
    ResultSet.CONCUR_UPDATABLE);

ResultSet uprs = stmt.executeQuery("SELECT * FROM usr");
uprs.moveToInsertRow();
uprs.updateString(2,"number 2");
uprs.updateString(3,"jhjh");
uprs.updateByte(4, (byte) 0);

uprs.insertRow();
uprs.moveToCurrentRow();
System.out.println("iserted"+uprs.rowInserted());

int id = uprs.getInt(1);
System.out.println("id="+id);

======
id is always returned as null
