Notatki

Informacja:

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.

Informacja:

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.

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;

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.
