SELECT * FROM users WHERE id IN (1,2,3)

When working with strings, extra care needs to be taken to avoid SQL Injection check out Security section for details. Objects can be retrieved using primary key by using Inline Conditions if the primary key is a number. SELECT * FROM `languages` ORDER BY `languages`.`code` LIMIT 1 no primary key defined, results will be ordered by first field (i.e., `Code`) works because model is specified using `db.Model()` SELECT * FROM `users` ORDER BY `users`.`id` LIMIT 1 works because destination struct is passed in Additionally, if no primary key is defined for relevant model, then the model will be ordered by the first field. They only work when a pointer to the destination struct is passed to the methods as argument or when the model is specified using db.Model(). The First and Last methods will find the first and last record (respectively) as ordered by primary key. If you want to avoid the ErrRecordNotFound error, you could use Find like db.Limit(1).Find(&user), the Find method accepts both struct and slice data Result.RowsAffected // returns count of records foundĮrrors.Is(result.Error, gorm.ErrRecordNotFound) SELECT * FROM users ORDER BY id DESC LIMIT 1 Get last record, ordered by primary key desc SELECT * FROM users ORDER BY id LIMIT 1 Get the first record ordered by primary key GORM provides First, Take, Last methods to retrieve a single object from the database, it adds LIMIT 1 condition when querying the database, and it will return the error ErrRecordNotFound if no record is found.
