事务死锁SqlMembershipProvider.CreateUser()

Question

我们运行一个小网站，在那里我们使用标准的SqlMembershipProvider，我们有一个标准的CreateUserWizard。

我们有一个未处理的异常：

事务(进程ID XX)与另一个进程在锁定资源上陷入僵局，并已被选择为死锁牺牲品。重新运行事务。

堆栈跟踪是

System.Web.Security.SqlMembershipProvider.CreateUser(String用户名，字符串密码，字符串电子邮件，字符串passwordQuestion，字符串passwordAnswer，布尔isApproved，Object providerUserKey，MembershipCreateStatus& status)

System.Web.UI.WebControls.CreateUserWizard.AttemptCreateUser()

知道怎么解决这个问题吗？

SQL查询是标准的：

是否有人在中以编辑模式(即:表锁)打开了表？

Answer 2

只需将@UserId设置为新的GUID即可。

set @User = NEWID();
