$conn
= oci_connect("hr", "hrpwd", "localhost/XE");
if (!
$conn) {
$m = oci_error();
trigger_error(htmlentities($m['message']), E_USER_ERROR);
}

$stid = oci_parse($conn, "create table emp2 as select * from employees");
oci_execute($stid);
echo
oci_num_rows($stid) . " lignes insérées.<br />\n";
oci_free_statement($stid);

$stid = oci_parse($conn, "delete from emp2");
oci_execute($stid, OCI_DEFAULT);
echo
oci_num_rows($stid) . " lignes effacées.<br />\n";
oci_commit($conn);
oci_free_statement($stid);

$stid = oci_parse($conn, "drop table emp2");
oci_execute($stid);
oci_free_statement($stid);

oci_close($conn);

Notes

Note:

Cette fonction ne retourne pas le nombre de lignes sélectionnées. Pour les commandes de type SELECT, cette fonction va retourner le nombre de ligne qui ont été lues dans le buffer avec oci_fetch*().

If you want to return te number of rows without fetching all data it might by more efficient to use this code (correct me if I'm wrong):

$sql_query = 'SELECT COUNT(*) AS NUMBER_OF_ROWS FROM (' . $your_query . ')';

$stmt= oci_parse($conn, $sql_query);

oci_define_by_name($stmt, 'NUMBER_OF_ROWS', $number_of_rows);

oci_execute($stmt);

oci_fetch($stmt);

echo $number_of_rows;

oci_num_rows() called after running i.e. TRUNCATE query, always returns 0.

<?php if ( oci_num_rows($result) == false ?>

You can use the snippet above to test out if a select statement returned any rows, it won't do a count but it comes in handy

It appears the easiest workaround if you want to get numrows without moving to the end of the result set is to use:

numrows = OCIFetchStatement(...);
OCIExecute(...);

So that the execute re-executes the query. It's horribly inefficient to query twice, but it works.

this function can be used with select statement, and also return affected number of rows.
But remember this, use this after fetch statement.
