> When a query creates multiple scans against a workbook, targeting different
> sheets using TABLE functions then the resulting datasets appear to get mixed
> with one overwriting the other. To reproduce, run the following query
> against the attachment and note that the value returned from the Products
> sheet is a name from the Customers sheet.
>
> {code:java}
> with cust as (
> select * from TABLE(dfs.tmp.`/Products_Customers_Orders.xlsx` (type =>
> 'excel', sheetName => 'Customers'))
> ),
> prod as (
> select * from TABLE(dfs.tmp.`/Products_Customers_Orders.xlsx` (type =>
> 'excel', sheetName => 'Products'))
> )
> select * from cust join prod on cust.Id = prod.Id;
> {code}
