The regression in the linked issue was found to be occurring from adding weight_string function due to order by as introduced in vitessio#7678. MySQL does not support the generated query - ```sql select ascii(val1) as a, count(*), weight_string(ascii(val1)) from aggr_test group by a order by a asc ``` In order to fix this, we also add the weight_string function to the group by clause as follows - ``` select ascii(val1) as a, count(*), weight_string(ascii(val1)) from aggr_test group by a, weight_string(ascii(val1)) order by a asc ``` Co-authored-by: Manan Gupta <[email protected]> Signed-off-by: Andres Taylor <[email protected]>
