SQL Server : 'Could not be bound' - Error - sql

Question

I have a dynamic stored procedure, it's long so I'll just provide the part that is causing the error.
SELECT #sSql = #sSql + '
animal.AnimalId,
species.Code AS Species,
breed.Code AS Breed ,
country.CountryId AS CountryId ,
country.Code AS CountryCode ,
animal.Sex AS Sex ,
animalRegistration.Identifier AS RegNo ,
breed.Description + country.Code + animal.Sex + animalRegistration.Identifier AS FullRegNo,
thePrefix.Prefix AS Prefix,
animal.Name AS Name,
thePrefix.Prefix + animal.Name AS FullName,
animal.Name AS EarTag1,
animal.DateOfBirth as DateOfBirth ,
0 as AnimalFlagCount'
--isnull( Genomics.GetAnimalFlagCount( a.AnimalId,' + CAST(#IsCatalogSamples AS VARCHAR(2)) + ' ), 0) AS AnimalFlagCount '
--a.EarTag1
SELECT #sFrom = '
FROM dbo.Animal AS animal
LEFT JOIN dbo.Breed breed ON animal.BreedId = breed.BreedId
LEFT JOIN dbo.Species species ON species.SpeciesId = breed.SpeciesId
LEFT JOIN dbo.AnimalIdentity animalIdentity ON animalIdentity.AnimalId = animal.AnimalId
LEFT JOIN dbo.AnimalIdentity animalRegistration ON animalRegistration.AnimalId = animal.AnimalId and animalRegistration.IdentityTypeId = 2
LEFT JOIN dbo.Country country ON animalIdentity.CountryId = country.CountryId
LEFT JOIN dbo.AnimalPrefix animalPrefix ON animalPrefix.AnimalId = animal.AnimalId
LEFT JOIN dbo.Prefix thePrefix ON thePrefix.PrefixId = animalPrefix.PrefixId
WHERE
'
This is returning the error:
Msg 4104, Level 16, State 1, Line 10
The multi-part identifier "thePrefix.Prefix" could not be bound.
Msg 4104, Level 16, State 1, Line 12
The multi-part identifier "thePrefix.Prefix" could not be bound.
When I create a query using this exact statement in a different window, it returns with out issue:
SELECT
animal.AnimalId,
species.Code AS Species,
breed.Code AS Breed ,
country.CountryId AS CountryId ,
country.Code AS CountryCode ,
animal.Sex AS Sex ,
animalRegistration.Identifier AS RegNo ,
breed.Description + country.Code + animal.Sex + animalRegistration.Identifier AS FullRegNo,
thePrefix.Prefix AS Prefix,
animal.Name AS Name,
thePrefix.Prefix + animal.Name AS FullName,
animal.Name AS EarTag1,
animal.DateOfBirth as DateOfBirth ,
0 as AnimalFlagCount
FROM dbo.Animal AS animal
LEFT JOIN dbo.Breed breed ON animal.BreedId = breed.BreedId
LEFT JOIN dbo.Species species ON species.SpeciesId = breed.SpeciesId
LEFT JOIN dbo.AnimalIdentity animalIdentity ON animalIdentity.AnimalId = animal.AnimalId
LEFT JOIN dbo.AnimalIdentity animalRegistration ON animalRegistration.AnimalId = animal.AnimalId and animalRegistration.IdentityTypeId = 2
LEFT JOIN dbo.Country country ON animalIdentity.CountryId = country.CountryId
LEFT JOIN dbo.AnimalPrefix animalPrefix ON animalPrefix.AnimalId = animal.AnimalId
LEFT JOIN dbo.Prefix thePrefix ON thePrefix.PrefixId = animalPrefix.PrefixId
where
animalRegistration.Identifier = '5573144'
Can anyone see why this is creating an issue? I realize it might not be possible with this much code, but I figured maybe I'm overlooking something big.
Thanks,

Are you maybe forgetting to concatenate #sFrom to #sSql before you execute it?
Try changing
SELECT #sFrom = ' FROM .....
to
SELECT #sSql = #sSql + ' FROM .....
You can also try inserting a print statement of the sql you are about to execute to make sure you are executing what you think you're executing. ...
Also, what is #sFrom declared as? Perhaps it's getting truncated right before the last join and hence the error?
Hope that helps
