我在PHP应用程序中有一条错误消息，该消息不断指向更新失败，但报告未授予我的Select命令。
SQLSTATE [42000]：语法错误或访问冲突：1142 SELECT 表'actionitems'的用户'vahejaba'@'localhost'命令被拒绝
这是触发vahejaba @ loalhost上的选择授予无效错误的更新方法。
为什么我会在更新时遇到选择错误，为什么我的用户名不正确（由于某种原因我认为是导致错误的原因，所以这是不正确的）？
请帮助。

在我的数据库（phpmyadmin）中，我有一个触发器，该触发器错误地指向了错误的用户名和错误的数据库名称。联系没有解决方案的Web主机后，我调查了触发器，并发现了问题。修改参数消除了错误。
