A report query data source returns a single row,

```python
v-- ITEMS
 +- Description
 +- LotId
 +- Material

```

I want a script data source to calculate a value based on values from the ITEMS data source.  
How do I address the individual columns in the query data source? e.g., a variation of the `data['ITEMS']` syntax?

The returned value of a query will be a `QueryResults` object:

> **[QueryResults](https://sdk.inductiveautomation.com/javadoc/ignition83/latest/com/inductiveautomation/reporting/common/api/QueryResults.html)**
>
> declaration: package: com.inductiveautomation.reporting.common.api, class: QueryResults

So probably you want [`coreResults`](https://sdk.inductiveautomation.com/javadoc/ignition83/latest/com/inductiveautomation/reporting/common/api/QueryResults.html#getCoreResults()) to get the underlying dataset.
