Activerecord has modified the behavior of
from(nil)
where it no longer substitutes withDUAL
, resulting in unexpected SQL generated.While this behavior change still retrieves the data from
@ids
correctly, it causes the returned result to include many rows (the quantity is equivalent to the number of records in the table), thereby causing performance issues.
