This PR implements the
to_sqlAPI, which converts a Cypher query into a plain SQL query, through DataFusion's SQLunparser. The API is also exposed through the Python bindings.Note that the API is an experimental feature, and there's a limitation for the API that all table names in the generated SQL are lowercased (e.g.,
Personbecomesperson,Companybecomescompany). This is because of the internal handling of DataFusion's SQLunparser. While this only affects the SQL string representation, actual query execution withexecute()handles case-sensitive labels correctly.
