fantacy2001 commented on issue #4861: two tables left join with different routing rules are not supported URL: https://github.com/apache/incubator-shardingsphere/issues/4861#issuecomment-601768249 > b.col is sharding key: > > > b.col = '123' However, by convention, two tables join, only the main table write value(a.col='123') in the where condition， The sub table obtains the value of the where condition through the ’on’ condition in the join. if both main table and sub table write value in the where condition, feel very uncomfortable
