Gets the number of rows affected during statement execution.
A valid OCI statement identifier.
Returns the number of rows affected as an integer, or false on failure
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.
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.
