如何返回某个变更集（或标记）并从该提交中分支出来？ 分支出来后，提交的更改不会影响原始分支吗？

INSERT INTO email_blast
(Send_Status
,member_status
,user_email
,usage_date_time
)
SELECT 0
     , 1
     , 'user@domain.tld'
     , NOW()
  FROM email_blast x
  LEFT JOIN email_blast y
    ON y.user_email = 'user@domain.tld'
   AND y.send_status IN (0,1)
   AND y.usage_date_time > NOW() - INTERVAL 5 MINUTE
 WHERE y.user_email IS NULL
 LIMIT 1;

SELECT * FROM email_blast;

hg commit

请注意，这是名为branches的分支，还有其他方法可以在Mercurial中进行分支。
