Current Version
Current version of Aspose.AdHoc does not support complicated querying, like querying on multiple tables.
However, we can create a bigger logic table that contains the real tables, and make queries on the logic table, instead of querying directly on the multiple tables.
We also provide a simple demo for this issue .
Developer plan
Our develop team are betaing the new version of Aspose.AdHoc, which will support advanced querying features such as querying on multiple tables.
