Hi there!

I have a view:

CREATE VIEW Uniao AS
SELECT * FROM Tabela1
UNION ALL
SELECT * FROM Tabela2

With SP3, it's work very well:

SELECT * FROM Uniao
LEFT OUTER JOIN Tabela3 ON
Uniao.CampoX = Tabela3.CampoX

With SP5a, don't works and this error is returned:

Msg 4409, Level 20, State 1
The columns in the query definition and the view definition
do not match.

Thanks for help me
