in case you are actually asking about CSV files (sorry, but what you
said about SQL queries confuses me), you should take a look to Tabels,

Hi,
I am looking for a open source software to convert csv file to RDF
based on one pre-defined ontology. Also, this converter should
support
complicated SQL queries (e.g., Group BY query and IF/THEN/ELSE query)
while defining the mapping between csv to our pre-defined ontology.
thanks
