SYMPTOMS
A View that has a Select statement with a CASE construct that does a sub- select with an IN clause may cause the client to access violate (AV) during a Select from the View.
The following sample is the problem View definition:
create view MyView as
Select Column1, Column2=
Case
When SomeColumn In
(Select SomeOtherColumn
From SomeOtherTable)
Then SomeValue
Else Null
End
From MyTable
A Select from MyView may cause the client to access violate.
WORKAROUND
Try to avoid the CASE construct inside a View Definition or perform some pre-processing for the CASE logic before the View Definition by using the IF-ELSE construct and Temporary Tables, and then define the View on the Temporary Table.
