Dear Experts,

I'm using(in C++) a SELECT statement in a Recordset (C++) to retrieve data from my DB (Oracle 8i). 

There are around 1 million records to be returned but when I performed the rs.Open , I can't get the 1 million records but only around 300.000 (the number of records returned change from one try to another).

I heard I should use a Cursor to perform that.

Is it the good solution ?

Any help greatly appreciated.

Jerome.

One solution may be better than another for your situation - it's difficult to have ageneral "rule of thumb" though. See ref-cursors. The ref cursor handle will be passed to your C++ program and it will retreive the results as needed. Ref-cursors are relatively new - C++ programs have been accessing large amounts of Oracle data forever, so it's certainly not the only solution.
