How to query the database? #83

Closed bazile-clyde closed 3 years ago

bazile-clyde commented 3 years ago

It looks like the store doesn't implement the query method. So calling query on a graph using RDFLib-SQLAlchemy as a store throws a NotImplementedError.

@bazile-clyde, please provide a code example showing what you've tried. The Store doesn't have to implement query for you to do SPARQL queries since the Graph will use the sparql plugin to parse the query and translate into calls to triples and `triples_choices'

@mwatts15 Ah that answers my question. Stepping through the code, I wondered why the store kept throwing a NotImplementedError when I queried the graph. But as you stated, it just ends up calling the query method from the SPARQL plugin. Thanks!
