## What is Presto

Presto is an open source distributed SQL query engine for running interactive analytic queries against data sources of all sizes ranging from gigabytes to petabytes.

## Install

```bash

$ composer require ytake/php-presto-client

```

## Usage

```php

execute();

// next call uri

$client->advance();

/** @var \Ytake\PrestoClient\QueryResult $result */

// current result

$result = $client->current();

// request cancel

$client->cancelLeafStage();

```

### bulk operations

```php

execute()->yieldResults();

// array

$result = $resultSession->execute()->getResults();

```

## Fetch Styles

### FixData Object

```php

execute()->yieldResults();

/** @var \Ytake\PrestoClient\QueryResult $row */

foreach ($result as $row) {

    foreach ($row->yieldData() as $yieldRow) {

        if ($yieldRow instanceof \Ytake\PrestoClient\FixData) {

            var_dump($yieldRow->offsetGet('column_name'), $yieldRow['column_name']);

        }

    }

}

```

### Array Keys

```php

execute()->yieldResults();

/** @var \Ytake\PrestoClient\QueryResult $row */

foreach ($result as $row) {

    /** @var array $item */

    foreach ($row->yieldDataArray() as $item) {

        if (!is_null($item)) {

            var_dump($item);

        }

    }

}

```

### Mapping Class

```php

execute()->yieldResults();

/** @var \Ytake\PrestoClient\QueryResult $row */

foreach ($result as $row) {

    foreach($row->yieldObject(Testing::class) as $object) {

        if ($object instanceof Testing) {

            var_dump($object);

        }

    }

}
