Installation

=================

1- First install sqlanywhere module for PHP Click Here!.

2- Use composer to install this package adding the lines bellow in the require section require: // ... "require": { "cagartner/SQLAnywhereClient": "dev-master" }, // ...

How to use

Bellow have some examples of how to use this class.

Connection SQLAnywhereClient::__construct:

<?php
    require '../vendor/autoload.php';

    use Cagartner\SQLAnywhereClient;

    try {
        $dns = "uid={user};pwd={password};ENG={database-name};commlinks=tcpip{host={host};port={port}}";
        $con = new SQLAnywhereClient( $dns );
    } catch (Exception $e) {
        echo $e->getMessage();
    }
?>

Você pode definir duas opções iniciais junto com a conexão, que são as seguintes: auto_commit e is_persistent. You can define two initials configuration params with the connection: auto_commit and is_persistent.

• auto_commit Enable auto commit, default is true;
• is_persistent Define persistent mode, default is false;

<?php
    require '../vendor/autoload.php';

    use Cagartner\SQLAnywhereClient;

    try {
        $dns = "uid={uid};pwd={password};ENG={};commlinks=tcpip{host={host};port={password}}";
        $autocommit = false;
        $persistent = true;

        $con = new SQLAnywhereClient( $dns, $autocommit, $persistent );
    } catch (Exception $e) {
        echo $e->getMessage();
    }
?>

Executing SQL commands SQLAnywhereClient::exec():

<?php

    $sql = "SELECT * FROM users";
    $result = $con->exec( $sql );

    echo "<pre>";
    print_r($result->fetch());
    echo "</pre>";
    exit;
?>

This method return an array with the data

<?php

    $sql = "SELECT name, email FROM users";

    foreach ($con->query( $sql ) as $result) {
        print_r($result);
    }
    exit;
?>

Retrieve just one line SQLAnywhereQuery::fetch

Return first row

<?php
    $sql = "SELECT name, email FROM users";
    $result = $con->exec( $sql );
    $user = $result->fetch();

    print_r($user);
    exit;
?>

Data format returns

You can choose how is the format that your data is retrieve SQLAnywhereClient

<?php
    // Retornar em um array com idexação por numero e coluna
    SQLAnywhereClient::FETCH_ARRAY;

    // Retornar em um array com idexação por coluna
    SQLAnywhereClient::FETCH_ASSOC; // Formato Padrão!

    // Retornar em um array com idexação por coluna
    SQLAnywhereClient::FETCH_OBJECT;

    // Retornar em um array com idexação por linha de dados
    SQLAnywhereClient::FETCH_ROW;

    // Retornar em um array com idexação por colunas
    SQLAnywhereClient::FETCH_FIELD;
?>

Example:

<?php

    $sql = "SELECT name, email FROM users";
    $result = $con->exec( $sql );
    $user = $result->fetch( SQLAnywhereClient::FETCH_OBJECT );

    print_r($user);
    exit;
?>

Return all rows SQLAnywhereQuery::fetchAll

Return all selected rows

<?php
    $sql = "SELECT name, email FROM users";
    $result = $con->exec( $sql );
    $user = $result->fetchAll();

    print_r($user);
    exit;
?>

In this method you also can choose the format of return too:

<?php

    $sql = "SELECT name, email FROM users";
    $result = $con->exec( $sql );
    $user = $result->fetchAll( SQLAnywhereClient::FETCH_OBJECT );

?>

?>

Or with count alias:

<?php
    $sql = "SELECT name, email FROM user";

    echo  "We find " . $result->count() . " itens.";
    exit;
?>

    }
    exit;
?>

Prepared Statement SQLAnywhereClient::prepare():

Prepared Statement with ?:

<?php
    $sql = "INSERT INTO users  name, email VALUES (?, ?)";
    $stmnt = $con->prepare( $sql );
    if ($stmnt->execute(array('Carlos', 'contato@carlosgartner.com.br'))) {
         echo $con->lastInsertId();
    }
    exit;
?>

And this params names:

<?php
    $sql = "INSERT INTO users  name, email VALUES (:name, :email)";
    $stmnt = $con->prepare( $sql );

    ))) {
         echo $con->lastInsertId();
    }
    exit;
?>

Bind Param SQLAnywherePrepared::bindParam():

<?php
    $sql = "INSERT INTO users  name, email VALUES (:name, :email)";
    $stmnt = $con->prepare( $sql );

    $name = "Carlos A.";
    $email = "contato@carlosgartner.com.br";

    $stmnt->bindParam(':name', $name);
    $stmnt->bindParam(':email', $email);

    if ($stmnt->execute()) {
         echo $con->lastInsertId();
    }
    exit;
?>
