Thank you for your usage and report.

$row->get(Type::INTEGER);

Could you input not Type::INTEGER but Type::LONG like sample/TQLAggregation.php ?

We must provide GridDB data type to the input of AggregationResult::get method.

| PHP data type  | GridDB data type | description    |
|----------------|------------------|----------------|
| int            | Type::LONG       | 64-bit integer |
| float          | Type::DOUBLE     | 64-bit float   |
| datetime       | Type::TIMESTAMP  |                |

I will review the API reference.
And I will also check the error handling.
