小编Mar*_*uan的帖子

有这个表结构:

CREATE TABLE `tableName` (
    `Id` int unsigned NOT NULL AUTO_INCREMENT PRIMARY KEY,
    `Status` enum('pending','rejected','sent','invalid') NOT NULL,
    `Body` varchar(255) NULL
) ENGINE='MyISAM' COLLATE 'utf8_general_ci';

我有这个(不完整)代码正常工作:

type StatusEnum string

const (
    STATUS_PENDING  StatusEnum = "pending"
    STATUS_REJECTED StatusEnum = "rejected"
    STATUS_SENT     StatusEnum = "sent"
    STATUS_INVALID  StatusEnum = "invalid"
)

func (s *StatusEnum) Scan(src interface{}) error {
    if src == nil {
        return errors.New("This field cannot be NULL")
    }

    if stringStatus, ok := src.([]byte); ok {
        *s = StatusEnum(string(stringStatus[:]))

        return nil …
