Calling oci_fetch_row() is identical to
OCI_NUM flag and returns the next row from the result
data as a numeric array.
Note: This function sets NULL fields to
PHP NULL value.
Subsequent calls to oci_fetch_row() will return the
next row from the result data or FALSE if there are no more rows.
For details on the data type mapping performed by
the oci8 driver, see the datatypes
supported by the driver
