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.You should take a look at Sparqlify - it's open-source https://github.com/AKSW/Sparqlify
Simple example is in the Sparqlify-CSV section of the readme file.
