flink TableEnvironment.sqlUpdate不支持update 多表关联更新吗

诸同仁好，flink TableEnvironment.sqlUpdate是不是不支持update 多表关联更新？


如下代码：
bbTableEnv.sqlUpdate("update order_tb a, min_max_usertime_tb b set a.mark=-2 " +
" where a.mac=b.mac and extract(epoch from a.usertime)/7200 = b.user_2hour " +
" and a.usertime > b.min_usertime and a.usertime < b.max_usertime");
报错如下：
