这是我正在尝试运行的查询：
UPDATE tblmatters SET
subMatterName = null,
matterName = 'Travelers v. Allstate',
dateOpen = '2011-04-13',
dateClosed = null,
orgAttorney_fk = 129,
billingAttorney_fk = 129,
responsibleAttorney_fk = 129,
typeOfLawCode_fk = 050,
updatedBy = 'RAINMAKR',
updatedOn = NOW()
WHERE parentID = 275 AND matterID = '00968'
每次尝试执行时，它都会挂起一个看起来像是在尝试运行查询的状态。我没有错误，没有停止，它将无限期地继续下去。我离开了一个多小时，它仍然坐在那里，试图执行。
关于这个问题的任何想法？如果您需要更多信息，请与我们联系！

答案 0 :(得分：6)
想出来。我的问题与一个从未提交或回滚的正在进行的事务有关 - 因此，我只是在这个过程进行时被卡住了。
如果MySQL会让你知道而不是只是拖延，那会很好，但是，我的问题已经避免了。

只有当另一个交易在同一行/页面上运行时，您的交易才会停止。 好好规划您的交易，以避免将来发生这种情况。
