我收到消息“请输入参数值.’：new’

当我单击确定结果消息是：

Warning:   Warning: execution completed with warning
sqlState:  null
ErrorCode: 17110
Position: 27
 
Query 1 of 1,Rows read: 0,Elapsed time (seconds) - Total: 0.023,sql query: 0.023,Building output: 0

在我的应用程序中,我收到一个错误“ORA-04098：trigger’CRW_INS_TRIG’无效并且重新验证失败”

这是否与松鼠有关？如果是这样,我该如何解决呢？
