Which grants are described both 'regular' and 'initial application'?
SELECT * FROM Grants AS T1 JOIN Documents AS T2 ON T1.grant_id   =   T2.grant_id JOIN Document_Types AS T3 ON T2.document_type_code   =   T3.document_type_code WHERE T3.document_description   =   'Regular' INTERSECT SELECT * FROM Grants AS T1 JOIN Documents AS T2 ON T1.grant_id   =   T2.grant_id JOIN Document_Types AS T3 ON T2.document_type_code   =   T3.document_type_code WHERE T3.document_description   =   'Initial Application'
grants described by both 'regular' and 'initial application' refers to using INTERSECT between two SELECT statements for each condition; joining tables Grants, Documents, and Document_Types to relate grants and their descriptions;
