cannot identify whether any string-type argument has been passed into the sum function during the compiling. Therefore, when you execute statements similar to select sum(string_col)from t, TiFlash returns always using the type inferred from the compiling. However, TiDB performs this calculation using a type that is more precise than that inferred from the compiling. Therefore, some SQL statements involving from t where a/b; Empty set (0.01 sec) 1368 In the example above, a/b’s inferred type from the compiling is Decimal(7,4) both in TiDB and in TiFlash.
