Found GDR Bug: At least I think it is.

This is not isolated to GDR, but seams to exist in Data Dude as well. If you create the following SQL:

1   1: CREATE VIEW [dbo].[v_SomeView] AS

1   2: SELECT    [BH].[Col1],

1   3:         [BH].[Col2],

1   4:         [BH].[Col3],

1   5:         [BH].[Col4],

1   6:         [BH].[Col5],

1   7:         CASE WHEN [BHPP].[OtherCol1] IS NULL THEN -1 ELSE 1 END As [Col6],

1   8:         CASE WHEN [BHPP].[OtherCol1] IS NULL THEN 'Not Applicable' ELSE 'PowerPack' END As [Col7],

1   9:         CASE WHEN [BHPP].[OtherCol1] IS NULL THEN [BH].[Col5] ELSE [BHPP].[OtherCol2] END As [Col8]

1  10: FROM    [dbo].[Table1] as [BH]

1  11:         LEFT JOIN     (SELECT [OtherCol1], [OtherCol2], [OtherCol3]

1  12:                     FROM    [$(CMD)].[dbo].[Table2]

1  13:                     WHERE    [OtherCol1] <> -1) as [BHPP]

1  14:             ON [BH].[Col2] = [BHPP].[Col2]

And add it to your Database project, but using proper table names :) You will get the following error for every use of [BHPP]:

Error 13 SR0029 : Microsoft.Validation : View: [dbo].[v_SomeView] contains an unresolved reference to an object. Either the object does not exist or the reference is ambiguous because it could refer to any of the following objects:….

This is a show stopper for us as we can’t (without good cause) be creating more views just to do a derived table…

I have submitted a Bug , so vote as you like, but please vote…
