oracle merge into 报 ora-02064错误

今天在用Oracle的merge into同步数据的时候，遇到了ora-02064：distributed operation not supported，这个错误的描述是说merge into不支持分布式事务操作。

百度了下网上说是10g的一个bug，

再查询了oracle的官方文档却说支持这种操作： 

You can specify this clause(这里是说match_insert_clause) by itself or with the merge_update_clause. If you

specify both, then they can be in either order.

解决的办法是：加上标红的语句加一个无实际意义的merge_update_clause,严格按照oracle的标准语法走
