Your problem is not clear as "no luck" is not very meaningful. Do you mean that no rows are found ? If so, check the value of the uniqueidentifier that is being used.

use tempdb

go

create table FOO

(FooIduniqueidentifiernot null default newid()

,FooDescrvarchar(255)not null

, constraint FOO_P primary key (FooId)

)

insert into FOO (FooDescr)

select 'First' union select 'Second'

select * from FOO

-- replace the value of FooId based on the select

select * from Foo where FooId = '9E3DF8B0-120B-47B4-B150-375B23EE9DDE'
