What's mean of the "T(C)"?
DECLARE @xml XML ='<root><id>1</id><id>2</id><id>3</id><id>4</id></root>'
SELECT
T.C.value('(text())[1]','varchar(20)')
FROM @xml.nodes('/root/id') AS T(C)
Note:can you give me a perfessional url,I want to see carefully.
thx very much.

From MSDN Nodes() Function syntax is
nodes (XQuery) as Table(Column)
Table(Column) Is the table name and the column name for the resulting rowset.
