Question

我已经创建了触发器，可以根据另一个表中的条目将数据插入到另一个表中。触发器已创建，但在表格中输入值后，会收到以下错误。

ORA-04091：表OOMUSER.EMTN_EVC_PAIR_STATUS正在变异，触发/功能可能看不到它

ORA-06512：at＆＃34; OOMUSER.PORTSTATUSUPDATE＆＃34;，第22行

ORA-04088：执行触发器时出错＆＃39; OOMUSER.PORTSTATUSUPDATE＆＃39;

您的错误消息ayss第22行是问题：

ORA-06512：at＆＃34; OOMUSER.PORTSTATUSUPDATE＆＃34;，第22行

确定Trigger Body源代码的行号并不是一门精确的科学，特别是当它被粘贴到StackOverflow中时，line 22表明这一行是麻烦似乎是合理的：

SELECT COUNT(OVEDS.EMTN_EVC_PAIRID) INTO ACTIVEPAIRB FROM OOM_VW_EMTN_DUALEVC_STATUS OVEDS WHERE OVEDS.EMTN_EVC_PAIRID

OOM_VW_EMTN_DUALEVC_STATUS是一个观点吗？如果是这样，它依赖什么表？我的猜测是EMTN_EVC_PAIR_STATUS功能。

插入新条目后触发器已创建但无法正常工作。显示ORA-04091错误
