oci_num_rows (PHP 5) oci_num_rows -- Returns number of rows affected during statement execution Descriptionint oci_num_rows ( resource stmt )
oci_num_rows() returns number of rows affected during statement execution.
注:
This function does not return number of rows selected!
For SELECT statements this function will return the number of rows, that were
fetched to the buffer with oci_fetch*() functions.

oci_num_rows() returns FALSE on error.
注:
In PHP versions before 5.0.0 you must use ocirowcount() instead.
This name still can be used, it was left as alias of
oci_num_rows() for downwards compatability.
This, however, is deprecated and not recommended.
