MORE INFORMATION

The state reported in the error message indicates where in the code that this particular error occurs. For example, the state for this error is eight (8). This particular fix only addresses 8624 errors where the state is eight.

The following code sample demonstrates the problem, as well as the suggested workaround of using TOP.

create table t (schedule nvarchar(3), lastdateentry smalldatetime, mileage char(1))
create table t1 (service_method varchar(3), transport_indicator varchar(1))
create table t2 (service_method varchar(3), transport_indicator varchar(1))
go
create view v as 
select service_method, transport_indicator from t1
UNION all
select service_method, transport_indicator from t2
go
--This query returns error 8624
SELECT Count(*) 
FROM t join v on t.Schedule = v.Service_Method  
Where t.lastdateentry =
	(select max(lastdateentry) from t
	 where mileage = v.transport_indicator)
go
--This rewritten version of the query works fine
SELECT Count(*) 
FROM t join v on t.Schedule = v.Service_Method  
Where t.lastdateentry =
	(select top 1 lastdateentry from t
	 where mileage = v.transport_indicator order by lastdateentry DESC)
