SQL Code Help Please
I have the following query producing a recordset drawn from 2 tables.
It produces a list of horses that a rider "wants" to have associated on their account and also a list of horses they have actually ridden.
I have been asked for a facility to hide horses from a riders account - which is more applicable to the ones they have actually ridden rather than associated (as they can easily remove this association)
A new table tblHideHorse has been created with HorseID and ClientID along with HorseHideID (identity)
How can I combine this into the above query to produce the list minus the horses they select to not show?
I know it is something along the lines of
where clientid not in (select ClientID from tblHideHorse) but im afraid that is the limit of my knowledge.
Thanks in advance

This is what you need-
Use NOT EXISTS instead of NOT IN. NOT IN does not consider NULLs and slow also.

Sorry must be being thick - pasted your code and it doesnt work.
Multi-part identifier r.ClientId could not be bound?
in the horsehide table it has to be an exact match for horse and rider together. Not just any horse or any rider existing in that table?
does that make sense?

Updated.
Please try ..changed alias name and added HorseID condition also.
