it mentioned on msdn link following .find() method if entity not found in context query sent database find entity there. null returned if entity not found in context or in database. find different using query in 2 significant ways: • round-trip database made if entity given key not found in context. • find return entities in added state. is, find return entities have been added context have not yet been saved database. but can cause problem? let's object marked added state, before saving database exception occurred. find might return object added state, have not been saved database later on. second concern, if .find found object in context , object updated in database after finding it, object version on context old? so benefits can using .find() instead of doing search based on primary key using .where or .firstordefault(a=>a.primarykey ==id) ? well docs state find... uses primary key value attempt find entity tracked co...

i using go-sql-driver/mysql insert ton of movies omdb data dump. parsing data , inserting following code: _, err = database.query("insert `movies` (`name`, `year`, `release_date`, `full_plot`, `genre`, `imdb_id`) values (?, ?, ?, ?, ?, ?)", movie.name, movie.year, movie.releasedate, movie.fullplot, movie.genre, movie.imdbid) if err != nil { return false, nil } return true, nil it works, 150 rows. doing wrong? your code seems discard error value returned, shouldn't do; handle gracefully. see error is, if you're opening many connections db, should use database connection pool , set (*db) setmaxopenconns value. (*db)query typically used select statements return rows, use (*db)exec or (*stmt)exec insert . i'd advise using db connection pool, , (*sql.db)prepare prepare statement , run inserts (even concurrently) using prepared statement. see https://golang.org/pkg/database/sql/#db.prepare
