Try something like this:

SQL

DECLARE @cols NVARCHAR(300)
DECLARE @dt NVARCHAR(1000)
DECLARE @pt NVARCHAR(2000)

SET @cols = STUFF((SELECT DISTINCT '],[' + [Name]
					FROM A
					ORDER BY '],[' + [Name]
			FOR XML PATH('')),1,2,'') + ']'

SET @dt = 'SELECT B.[ID], B.[Text], B.[Value] ' +
		'FROM A LEFT JOIN B ON A.[ID] = B.[ID] '
--EXEC(@dt)

SET @pt = 'SELECT [ID], ' + @cols + ' ' +
		'FROM (' + @dt + ') AS DT ' +
		'PIVOT(MAX([Value]) FOR [Text] IN (' + @cols + ')) AS PT ' + 
		'ORDER BY [ID]'
EXEC(@pt)
