db2_fetch_row

(PECL)

db2_fetch_row -- Sets the result set pointer to the next row or requested row

Opis

bool db2_fetch_row ( resource stmt [, int row_number] )

Use db2_fetch_row() to iterate through a result set, or to point to a specific row in a result set if you requested a scrollable cursor.

To retrieve individual fields from the result set, call the db2_result() function.

Rather than calling db2_fetch_row() and db2_result(), most applications will call one of db2_fetch_assoc(), db2_fetch_both(), or db2_fetch_array() to advance the result set pointer and return a complete row as an array.

Parametry

stmt: A valid stmt resource.
row_number: With scrollable cursors, you can request a specific row number in the result set. Row numbering is 1-indexed.

Zwracane wartości

Returns TRUE if the requested row exists in the result set. Returns FALSE if the requested row does not exist in the result set.

Przykłady

Przykład 1. Iterating through a result set

The following example demonstrates how to iterate through a result set with db2_fetch_row() and retrieve columns from the result set with db2_result().

<?php

                $sql = 'SELECT name, breed FROM animals WHERE weight < ?';

                $stmt = db2_prepare($conn, $sql);
db2_execute($stmt, array(10));

                while (db2_fetch_row($stmt)) {

                    $name = db2_result($stmt, 0);

                    $breed = db2_result($stmt, 1);

                    print "$name $breed";

                }
?>
