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'
每次我尝试执行时，它都会挂起，看起来像是在尝试运行查询。我没有错误，没有停止，它将无限期地继续下去。我已经把它放了一个多小时，它仍然坐在那里，试图执行。
关于这个问题是什么的任何想法？如果您需要更多信息，请告诉我！
