db2_result

(PECL)

db2_result --  Returns a single column from a row in the result set

説明

mixed db2_result ( resource stmt, mixed column )

Use db2_result() to return the value of a specified column in the current row of a result set. You must call db2_fetch_row() before calling db2_result() to set the location of the result set pointer.

パラメータ

stmt

A valid stmt resource.

column

Either an integer mapping to the 0-indexed field in the result set, or a string matching the name of the column.

返り値

Returns the value of the requested field if the field exists in the result set. Returns NULL if the field does not exist, and issues a warning.

例 1. A db2_result() example

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, 'BREED');
    print
"$name $breed";
}
?>

上の例の出力は以下となります。

cat Pook
gold fish Bubbles
budgerigar Gizmo
goat Rickety Ride
