Use ocilib c + + interface programming, when using OCI_Prepare (st, "BEGIN stored procedure name (: 1, 2,, 3); END." ) and OCI_Execute call a stored procedure, can get the result set is normal; Now want to OCI_SetFetchMode (st, OCI_SFM_SCROLLABLE), for processing The result set, The article from a specific number of fore and aft and flexibility to begin to value, but found in OCI_FetchLast OCI_FetchSeek will move The cursor position error, The statement is not scrollable,,,

How can through ocilib interface implementation flexibility in fore and aft of the stored procedure and article from a specific number of values start?
PS: above to common SQL can realize OCI_FetchLast, OCI_FetchSeek, now what is the value realization of the stored procedure,
