What do you mean by "it doesn't work" - try to explain what teh problem is. Does it select data you didn't intend? Select no data? Or throw an exception?

may be it doesnt find any result where your center table name column = a
i think you need to use like.

SQL

SELECT  r.[Name] FROM [Center] c
INNER JOIN SwitchType s ON c.[ID] = s.[ID]
RIGHT JOIN [ReportType] r ON c.[ID]= r.[ID]
where c.[Name] like 'a%'
