Returns an object in which each property represents a column returned in
the row fetched from a result set.
パラメータ
- stmt
A valid stmt resource containing a result set.
- row_number
Requests a specific 1-indexed row from the result set. Passing this
parameter results in a PHP warning if the result set uses a
forward-only cursor.
戻り値
Returns an object representing a single row in the result set. The
properties of the object map to the names of the columns in the result set.
The IBM DB2, Cloudscape, and Apache Derby database servers typically fold
column names to upper-case, so the object properties will reflect that case.
If your SELECT statement calls a scalar function to modify the value
of a column, the database servers return the column number as the name of
the column in the result set. If you prefer a more descriptive column name
and object property, you can use the AS clause to assign a name to the
column in the result set.
Returns FALSE if no row was retrieved.
例
例 1. A db2_fetch_object() example
The following example issues a SELECT statement with a scalar function,
RTRIM, that removes whitespace from the end of the column. Rather than
creating an object with the properties "BREED" and "2", we use the AS
clause in the SELECT statement to assign the name "name" to the modified
column. The database server folds the column names to upper-case,
resulting in an object with the properties "BREED" and "NAME".
|
<?php
$conn = db2_connect($database, $user, $password);
$sql = "SELECT breed, RTRIM(name) AS name
FROM animals
WHERE id = ?";
if ($conn) {
$stmt = db2_prepare($conn, $sql);
db2_execute($stmt, array(0));
while ($pet = db2_fetch_object($stmt)) {
echo "Come here, {$pet->NAME}, my little {$pet->BREED}!";
}
db2_close($conn);
}
?>

上の例の出力は以下となります: Come here, Pook, my little cat! |
