EXAMPLES-WITH-PDO_4D(3) 1 EXAMPLES-WITH-PDO_4D(3)Examples with PDO_4D - Examples PDO_4D
This basic example show how to connect, execute a query, read data and disconnect from a 4D SQL server.
Example #1
Basic example with PDO_4D
<?php
$dsn = '4D:host=localhost;charset=UTF-8';
$user = 'test';
$pass = 'test';
// Connection to the 4D SQL server
$db = new PDO($dsn, $user, $pass);
try {
$db->exec('CREATE TABLE test(id varCHAR(1) NOT NULL, val VARCHAR(10))');
} catch (PDOException $e) {
die("Erreur 4D : " . $e->getMessage());
}
$db->exec("INSERT INTO test VALUES('A', 'B')");
$db->exec("INSERT INTO test VALUES('C', 'D')");
$db->exec("INSERT INTO test VALUES('E', 'F')");
$stmt = $db->prepare('SELECT id, val from test');
$stmt->execute();
print_r($stmt->fetchAll());
unset($stmt);
unset($db);
?>
The above example will output:
Array
(
[0] => Array
(
[ID] => A
[0] => A
[VAL] => B
[1] => B
)
[1] => Array
(
[ID] => C
[0] => C
[VAL] => D
[1] => D
)
[2] => Array
(
[ID] => E
[0] => E
[VAL] => F
[1] => F
)
)
This example shows how to execute a query in 4D language, and how to read the result through PDO_4D.
Example #2
Accessing 4D language from pdo_4d
Set up a 4D method, called method. Make sure in the method properties that the option Available via SQL is checked. The 4D code is
the following.
C_TEXTE($0)
$0:=Version application(*);
The PHP code to use the above 4D method is :
<?php
$dsn = '4D:host=localhost;charset=UTF-8';
$user = 'test';
$pass = 'test';
// Connection to the 4D server
$db = new PDO($dsn, $user, $pass);
$stmt = $db->prepare('SELECT {FN method() AS VARCHAR } FROM _USER_SCHEMAS LIMIT 1');
$stmt->execute();
print_r($stmt->fetchAll());
unset($stmt);
unset($db);
?>
The above example will output:
(
[0] => Array
(
[<expression>] => F0011140
[0] => F0011140
)
)
Example #3
Escaping 4D table names
This examples illustrates how to escape characters in a 4D SQL query.
<?php
$dsn = '4D:host=localhost;charset=UTF-8';
$user = 'test';
$pass = 'test';
// Connection to 4D server 4D
$db = new PDO($dsn, $user, $pass);
$objects = array('[',']','[]','][','[[',']]','[[[',']]]','TBL ]]32[23');
foreach($objects as $id => $object) {
$object = str_replace(']',']]', $object);
print "$object
";
$db->exec('CREATE TABLE IF NOT EXISTS ['.$object.'](['.$object.'] FLOAT)');
$req = "INSERT INTO [$object] ([$object]) VALUES ($id);";
$db->query($req);
$q = $db->prepare("SELECT [$object] FROM [$object]");
$q->execute();
$x[] = $q->fetch(PDO::FETCH_NUM);
$db->exec('DROP TABLE ['.$object.'];');
}
?>
The above example will output:
[
]]
[]]
]][
[[
]]]]
[[[
]]]]]]
TBL ]]]]32[23
