Method Pluck

finisher_api.go:571–590

Pluck queries a single column from a model, returning in the slice dest. E.g.: var ages []int64 db.Model(&users).Pluck("age", &ages)

(column string, dest interface{})

//	var ages []int64
//	db.Model(&users).Pluck("age", &ages)
func (db *DB) Pluck(column string, dest interface{}) (tx *DB) {
	tx = db.getInstance()
	if tx.Statement.Model != nil {
		if tx.Statement.Parse(tx.Statement.Model) == nil {
			if f := tx.Statement.Schema.LookUpField(column); f != nil {
				column = f.DBName
			}
		}
	}

	if len(tx.Statement.Selects) != 1 {
		fields := strings.FieldsFunc(column, utils.IsInvalidDBNameChar)
		tx.Statement.AddClauseIfNotExists(clause.Select{
			Distinct: tx.Statement.Distinct,
			Columns:  []clause.Column{{Name: column, Raw: len(fields) != 1}},
		})
	}
	tx.Statement.Dest = dest
	return tx.callbacks.Query().Execute(tx)
}

func (db *DB) ScanRows(rows *sql.Rows, dest interface{}) error {
