WSO2 CEP和SQL Server插入SQL Server端设置的主键

Question

我在SQL Server上有一个数据库，该数据库的表具有以下结构：

ID has IDENTITY set to true. 

当我进入WSO2 CEP并尝试使流将其事件转储到表中时，出现以下错误：

from MessageStream
insert into msg;

Error while dispatching events: Error while adding events to event table, Cannot insert explicit value for identity column in table 'EDS_MSG' when IDENTITY_INSERT is set to OFF.

org.wso2.siddhi.core.exception.ExecutionPlanRuntimeException: Error while adding events to event table, Cannot insert explicit value for identity column in table 'EDS_MSG' when IDENTITY_INSERT is set to OFF.

有没有一种方法可以使用SiddhiQL不发送ID并让SQL Server以自动递增的方式处理该主键 ？

Answer 1

尝试从define table msg删除ID int 。

@From(eventtable='rdbms', datasource.name='WSO2_TRX_DB', table.name='EDS_MSG')
define table msg (Descri string, StartDate long, EndDate long, UpdateDate long, LastUser string);

from MessageStream
insert into msg;
