WITH (nolock) vs nolock ??

I read somewhere that starting SQL server 2005 the nolock hint will not work by itself, but you will need to add 'with nolock'.
Can someone point me to the Microsoft article that mentions this.

Thanks!

I think I had read that before, but I've been using 2005 for quite some time now and NOLOCK works fine

select * from tablename (nolock)

Excerpt from:
http://msdn.microsoft.com/en-us/library/ms187373(SQL.90).aspx


In SQL Server 2005, with some exceptions, table hints are supported in the FROM clause only when the hints are specified with the WITH keyword. Table hints also must be specified with parentheses.

The following table hints are allowed with and without the WITH keyword: NOLOCK, READUNCOMMITTED, UPDLOCK, REPEATABLEREAD, SERIALIZABLE, READCOMMITTED, FASTFIRSTROW, TABLOCK, TABLOCKX, PAGLOCK, ROWLOCK, NOWAIT, READPAST, XLOCK, and NOEXPAND. When these table hints are specified without the WITH keyword, the hints should be specified alone. For example:

FROM t (FASTFIRSTROW)
When the hint is specified with another option, the hint must be specified with the WITH keyword:

FROM t WITH (FASTFIRSTROW, INDEX(myindex))
The restrictions apply when the hints are used in queries against databases with the compatibility level of 90.

Agree with Tim and Brandon, I have used both ways without issue.  When you use the hint in views or other areas where the SQL is changed on save, you will see that when you go back in it now says WITH (NOLOCK). ;)

I am going to upgrade our servers from sql server 2000 to 2008 and have tons of stored procs missing the 'with' keyword.
i read somewhere that sql server 2008 completely ignores the hint when "with" is not specified.

SQL 2008 BOL on Table hints:
http://msdn.microsoft.com/en-us/library/ms187373.aspx

Omitting the WITH keyword is a deprecated feature: This feature will be removed in a future version of Microsoft SQL Server. Avoid using this feature in new development work, and plan to modify applications that currently use this feature.
