oci_num_rows
(PHP 5)
oci_num_rows -- Returns number of rows affected during statement execution
Description
int
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.
例子 1. oci_num_rows() example
<?php echo "<pre>"; $conn = oci_connect("scott", "tiger"); $stmt = oci_parse($conn, "create table emp2 as select * from emp"); oci_execute($stmt); echo oci_num_rows($stmt) .

" rows deleted.<br />"; oci_commit($conn); oci_free_statement($stmt); $stmt = oci_parse($conn, "drop table emp2"); oci_execute($stmt); oci_free_statement($stmt); oci_close($conn); echo "</pre>"; ?>

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.
