I agree. Query 3 is the MODIFY FILE while Query 2 is ADD FILE:

-- Query 1

ALTER DATABASE AdventureWorks2012

ADD FILE (NAME=ADW2012 REPLACES Adventureworks2012_data)

[highlight=#ffff11]

-- query 2

ALTER DATABASE AdventureWorks2012

ADD FILE (NAME=AdventureWorks2012_data, NEWNAME=AWD2012 );

[/highlight]

[highlight=#ffff11]

-- query 3

ALTER DATABASE AdventureWorks2012

MODIFY FILE (OLDNAME=AdventureWorks2012_data, Newname= AWD2012);

[/highlight]

-- query 4

ALTER DATABASE AdventureWorks2012

ADD FILE (NEWNAME=AWD2012, OLDNAME=AdventureWorks2012_data );
