INSERT INTO CommentTable (OtherWID, Comm) VALUES ('5', 'Tester"s comment');

// A new WID is automatically obtained by the Protein class

Protein protein = new Protein (2); protein. setName("Sample Name"); protein. set AASequence("XXX"); protein. addComment ("Tester's comment"); protein. storeQ;

Retrieve an existing entry in the Protein table and alter some of its data.
