Table schema:
CREATE TABLE Ref_document_types (document_type_name VARCHAR, document_type_description VARCHAR, document_type_code VARCHAR); CREATE TABLE Documents (Document_date VARCHAR, document_type_code VARCHAR)

Question: What is the document type name and the document type description and creation date for all the documents?
SQL: SELECT T1.document_type_name, T1.document_type_description, T2.Document_date FROM Ref_document_types AS T1 JOIN Documents AS T2 ON T1.document_type_code = T2.document_type_code
