Find det rigtige kolonnenavn på et alias, der bruges i en visning?

Givet denne opfattelse:

CREATE VIEW viewTest
AS
SELECT
    books.id,
    books.author,
    Books.title AS Name
FROM
    Books

Hvad jeg kan se, kan du få brugt kolonnerne og tabellerne ved at gøre dette:

SELECT * 
FROM INFORMATION_SCHEMA.VIEW_COLUMN_USAGE AS UsedColumns 
WHERE UsedColumns.VIEW_NAME='viewTest'

SELECT * 
FROM INFORMATION_SCHEMA.VIEW_TABLE_USAGE AS UsedTables 
WHERE UsedTables.VIEW_NAME='viewTest'

Dette er til sql server 2005+. Se reference her

Giv det samme syn. Prøv denne forespørgsel:

SELECT
    c.name AS columnName,
    columnTypes.name as dataType,
    aliases.name as alias
FROM 
sys.views v 
JOIN sys.sql_dependencies d 
    ON d.object_id = v.object_id
JOIN .sys.objects t 
    ON t.object_id = d.referenced_major_id
JOIN sys.columns c 
    ON c.object_id = d.referenced_major_id 
JOIN sys.types AS columnTypes 
    ON c.user_type_id=columnTypes.user_type_id
    AND c.column_id = d.referenced_minor_id
JOIN sys.columns AS aliases
    on c.column_id=aliases.column_id
    AND aliases.object_id = object_id('viewTest')
WHERE
    v.name = 'viewTest';

Det returnerer dette for mig:

columnName  dataType  alias

id          int       id
author      varchar   author
title       varchar   Name

Dette er også testet i sql 2005+
