HI SQL Experts,
I have a simple SQL query to join 2 tables:

select veh.[YEAR],veh.MAKE,veh.model,veh.TRIMLIST,veh.ICID,vif.[vif #] from [TheVehListBeta2015-04-21] veh
   inner join [vifList2015-05-04] vif
   on veh.[YEAR]=vif.Yr
   and veh.MAKE=vif.make
   and veh.MODEL=vif.model
   and  (TRIMLIST like '%' + vif.Trim + '%' + Convert(nvarchar(10),vif.Drs) + '%' + vif.Body + '%' )
   order by [YEAR],MAKE,model

The result of this query is: 4983 records
If I use the same query to update the number is different. Here is 2 different queries to update I have tried:
(1)

update [TheVehListBeta2015-04-21]  set EVOXID=vif.[vif #]
from [vifList2015-05-04] vif
Where [TheVehListBeta2015-04-21].YEAR=vif.Yr
and [TheVehListBeta2015-04-21].MAKE=vif.Make
and [TheVehListBeta2015-04-21].MODEL=vif.Model
 and  TRIMLIST like '%' + vif.Trim + '%' + Convert(nvarchar(10),vif.Drs) + '%' + vif.Body + '%' 

(2)

update [TheVehListBeta2015-04-21] 
   set [TheVehListBeta2015-04-21].EVOXID=vif.[VIF #]
   from [TheVehListBeta2015-04-21] veh inner join [vifList2015-05-04] vif 
   on veh.[YEAR]=vif.Yr
   and veh.MAKE=vif.make
   and veh.MODEL=vif.model
   and  (TRIMLIST like '%' + vif.Trim + '%' + Convert(nvarchar(10),vif.Drs) + '%' + vif.Body + '%' )

UPDATE query gives: (4192 row(s) affected)

Does anyone know where is the difference?
Thank you!
