Re: error when using move, any suggestions?

Noel,

Well, your sql in the driver was fetch forward 2000 in test, does that
work?

It shouldn't be a driver error, the driver just passes sql through.

Ok, sorry, jdbc is getting in the way here. I haven't got time right

Noel,

Ok, I have some test code that works

public CursorTest()
{
Connection con = null;
ResultSet rs;
try{
con = getConnection();
con.setAutoCommit( false );
Statement stmt = con.createStatement();

int result = stmt.executeUpdate( "declare test cursor for select *
from orders" );
System.out.println( "Created cursor, result is " + result );
result = stmt.executeUpdate( "move 5 in test");
System.out.println( "Moved " + result );
for(;;)
{
rs = stmt.executeQuery("fetch forward 5 in test");
if ( !rs.next() )
break;
}

while(rs.next()){
System.out.println("Id -->" + rs.getObject(1).toString());
}
rs.close();
con.commit();
con.close();
}catch (Exception ex){
ex.printStackTrace();
}finally{
try{
if (null != con) con.close();
}catch(Exception ex){}
}
}

note the fetch is actually going to return the result set, so you have
to do rs=executeQuery( "fetch ..." )
