> We can just change it to **left join**, and add logic to check if more than 1 row is returned in left join. I don't think that's possible. A cross join is used as that doesn't require a join condition. The cross join is less efficient however, as it repeats the value for the scalar as much as there are values on the left side, and then uses that to filter on (which is less efficient than using a scalar in the filter). -- This is an automated message from the Apache Git Service.
