Sets the number of rows to be prefetched after successful call to
oci_execute().
Return Values
Returns TRUE
on success or FALSE
on failure.
Notes
Note:
In PHP versions before 5.0.0 you must use ocisetprefetch() instead.
This name still can be used, it was left as alias of
oci_set_prefetch() for downwards compatability.
This, however, is deprecated and not recommended.
