    Unanswered: CLI: how to get result set size

    Hi All,

    Is it possible for a C/C++ program using the CLI/ODBC interface to get the size of
    a returned result set? I cannot find a function that can do that directly. Of course it is possible execure another statement with the same where clause that can use count(*)
    but then I would have a penalty of executing additional statement. Is it possible somehow
    to get the size of a result set using scrollable cursors? I would like to get the size before
    I have started fetching it.

    In some cases, the rows are not retrieved from the database until you fetch them, so it is not possible.
