[英]PDO binding two array of values
I add a lot a values with params ( $queryArr
) in INSERT
statemnt in foreach
我在foreach
INSERT
语句中添加了很多带有 params ( $queryArr
) 的值
public function getClients()
{
helper::putToLog("\n----- getClients\n", true);
$managedCustomerService = $this->user->GetService('ManagedCustomerService', ADWORDS_VERSION);
$selector = new Selector();
$selector->fields = array("CustomerId", "Name", "CurrencyCode");
$graph = $managedCustomerService->get($selector);
if (isset($graph->entries)) {
$accounts = [];
foreach ($graph->entries as $account) {
$accounts[$account->customerId] = $account;
}
helper::putToLog('Clients found: '.count($accounts)."\n", true);
} else {
helper::putToLog('Clients not found'."\n", true);
return false;
}
$sth = $this->db->prepare('UPDATE `adwords_clients_google` set status = 2');
$sth->execute();
$sth = null;
$queryClients = "INSERT INTO `adwords_clients_google` (`client_foreign_id`, `status`, `client_name`, `client_currency`) VALUES";
foreach($accounts as $account) {
$queryArr[$account->customerId] = "(".$account->customerId.", 1, :".$account->customerId.", :".$account->customerId."_currencyCode)";
$nameArr[$account->customerId] = $account->name;
$currencyArr[$account->customerId."_currencyCode"] = $account->currencyCode;
}
$queryClients .= implode(',', $queryArr) . " ON DUPLICATE KEY UPDATE `status` = VALUES(`status`), `client_name` = VALUES(`client_name`) ";
$sth = $this->db->prepare($queryClients);
foreach ($nameArr as $key => $value) {
$sth->bindValue(":$key", str_replace("'", "\'", $value), PDO::PARAM_STR);
}
foreach ($currencyArr as $key => $value) {
$sth->bindValue(":$key", $value, PDO::PARAM_STR);
}
print_r($sth);
try {
if ($sth->execute()) {
helper::putToLog('ok queryCampaignArr, inserted rows: ' . $sth->rowCount());
} else {
helper::putToLog('not ok', true);
}
} catch (Exception $ex) {
helper::putToLog($sth->debugDumpParams(), true);
helper::putToLog("ERROR: ".$ex->getMessage(), true);
}
return true;
}
and there are 2 array of values I need to bind $nameArr
and $currencyArr
.我需要绑定 2 个值数组$nameArr
和$currencyArr
。 I didn't get any errors but column client_currency
is empty even though array $currencyArr
contains all necessary values.我没有收到任何错误,但即使数组$currencyArr
包含所有必需的值,列client_currency
也是空的。 What's wrong?怎么了?
It looks like you haven't grasped the concept of prepared+paramterized statements yet.看起来您还没有掌握准备+参数化语句的概念。
You prepare them once and then execute them with varying parameters (one or) multiple times.您准备一次,然后使用不同的参数(一个或多个)执行它们。
$sth = $this->db->prepare('
INSERT INTO
`adwords_clients_google`
(`client_foreign_id`, `status`, `client_name`, `client_currency`)
VALUES
(:id, 1, :name, :currency)
ON DUPLICATE KEY UPDATE
`status` = VALUES(`status`),
`client_name` = VALUES(`client_name`)
');
$sth->bindParam(':id', $id);
$sth->bindParam(':name', $name);
$sth->bindParam(':currency', $currency);
foreach($accounts as $account) {
$id = $account->customerId;
$name = $account->name;
$currency = $account->currencyCode;
$sth->execute();
}
if you haven't got any error message/log entries please make sure that the error handling mode of your PDO instance really is set to PDO::ERRMODE_EXCEPTION.如果您没有收到任何错误消息/日志条目,请确保您的 PDO 实例的错误处理模式确实设置为 PDO::ERRMODE_EXCEPTION。
edit: to illustrate that, here's an sscce :编辑:为了说明这一点,这是一个sscce :
<?php
$pdo = new PDO('mysql:host=localhost;dbname=test;charset=utf8', 'localonly', 'localonly', array(
PDO::ATTR_EMULATE_PREPARES=>false,
PDO::MYSQL_ATTR_DIRECT_QUERY=>false,
PDO::ATTR_ERRMODE=>PDO::ERRMODE_EXCEPTION
));
setup($pdo); // creating temporary table + sample data for this example
printTable("before", $pdo);
$sth = $pdo->prepare('
INSERT INTO
`soFoo`
(`client_foreign_id`, `status`, `client_name`, `client_currency`)
VALUES
(:id, 1, :name, :currency)
ON DUPLICATE KEY UPDATE
`status` = VALUES(`status`),
`client_name` = VALUES(`client_name`)
');
$sth->bindParam(':id', $id);
$sth->bindParam(':name', $name);
$sth->bindParam(':currency', $currency);
$accounts = data();
foreach($accounts as $account) {
$id = $account->customerId;
$name = $account->name;
$currency = $account->currencyCode;
$sth->execute();
}
printTable("after", $pdo);
function data() {
return array_map(function($e) { return (object)$e; }, array(
array('customerId'=>1, 'name'=>'customerA', 'currencyCode'=>'cA'),
array('customerId'=>2, 'name'=>'customerB', 'currencyCode'=>'cB'),
));
}
function printTable($cap, $pdo) {
echo $cap, "\r\n";
foreach( $pdo->query('SELECT * FROM soFoo', PDO::FETCH_ASSOC) as $r ) {
echo join(', ', $r), "\r\n";
}
}
function setup($pdo) {
$pdo->exec('
CREATE TEMPORARY TABLE soFoo (
client_foreign_id int,
`status` int,
client_name varchar(32),
client_currency varchar(32),
unique(client_foreign_id)
)
');
$pdo->exec("INSERT INTO soFoo (client_foreign_id,status,client_name,client_currency) VALUES (1, 0, 'agent smith', 'kruegerrand')");
}
prints印刷
before
1, 0, agent smith, kruegerrand
after
1, 1, customerA, kruegerrand
2, 1, customerB, cB
