Question

我是PHP新手。我试图将数据插入表中。在运行该程序时，它显示成功，但在检查oracle 10g数据库时，它显示 未找到数据 。创建表时发生了同样的事情，它显示 表或视图不存在。

这是我的代码=

<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
<title>Untitled Document</title>
</head>

<body>
<h1><u>Inserting data into Table</u></h1>

<?php
// Create connection
$conn = oci_connect('SYSTEM', 'xxxx', 'localhost/XE');
// Check connection
if (!$conn) {
    die("Connection failed: " . oci_error());
}


$sql = "insert into MYGUESTS (ID, FIRSTNAME, LASTNAME, EMAIL) values (12, 'John', 'Doe', 'john@example.com')";
$stid=oci_parse($conn, $sql);
if(!$stid){
$e=oci_error($conn);
trigger_error(htmlentities($e[message],ENT_QUOTES),E_USER_ERROR);
}
else
 {
    echo "Successfull";
 }
oci_close($conn);
?>
</body>
</html>

为什么我在oracle数据库中看不到任何数据？问题出在哪里？

您遗失了commit和execute

来自php.net的OCI示例：

<?php

// Insert into several tables, rolling back the changes if an error occurs

$conn = oci_connect('hr', 'welcome', 'localhost/XE');

$stid = oci_parse($conn, "INSERT INTO mysalary (id, name) VALUES (1, 'Chris')");

// The OCI_NO_AUTO_COMMIT flag tells Oracle not to commit the INSERT immediately
// Use OCI_DEFAULT as the flag for PHP <= 5.3.1.  The two flags are equivalent
$r = oci_execute($stid, OCI_NO_AUTO_COMMIT);
if (!$r) {    
    $e = oci_error($stid);
    trigger_error(htmlentities($e['message']), E_USER_ERROR);
}

$stid = oci_parse($conn, 'INSERT INTO myschedule (startday) VALUES (12)');
$r = oci_execute($stid, OCI_NO_AUTO_COMMIT);
if (!$r) {    
    $e = oci_error($stid);
    oci_rollback($conn);  // rollback changes to both tables
    trigger_error(htmlentities($e['message']), E_USER_ERROR);
}

// Commit the changes to both tables
$r = oci_commit($conn);
if (!$r) {
    $e = oci_error($conn);
    trigger_error(htmlentities($e['message']), E_USER_ERROR);
}

?>

使用Oracle和PHP插入数据或创建表或更新数据时出现问题
