Nothing I do changes the format of the date.
declare @.PubDate datetime
set @.PubDate = convert(varchar,getdate(),111)
SELECT @.PubDate,*
FROM OPENquery(MySQL, 'SELECT * FROM articles WHERE Weight = 3 AND
DateInserted >= DATE_SUB(@.PubDate,INTERVAL 15 DAY) ')
I need it to show the date like yyyy/mm/ddYou can't change the display if it is the variable is declared as a datetime
datatype with convert. Make it a varchar instead.

>|||Thank you. Your answer fixed the formatting issue, but my query doesn't
return any results when it should. It returns results if I hard code the dat
e
in y/m/d format in place of the @.PubDate in my query. I tried
convert(datetime, getdate(), 111), but that, did not solve my problem. Any
other sugestions?

I'm surprised this doesn't throw an error, because @.PubDate cannot
be used within the OPENQUERY statement. In addition, since you
have declared @.PubDate as datetime, it does not have a format, and
when used where a string is expected, it will be converted using the
default string format.
You have two options, unless you've hidden some secret about
how @.PubDate is working in the query:
If you are using SQL Server 2005, you can do this:
EXECUTE(
N'SELECT ?, * FROM articles
WHERE Weight = 3 AND DateInserted >= DATE_SUB(?,INTERVAL 15 DAY)',
@.PubDate, @.PubDate) at MySQL
You may or may not have to declare @.PubDate as a string and pre-convert
it--I don't know what your DATE_SUB function expects.
Alternatively, you can create the entire openquery string dynamically:
DECLARE @.sql nvarchar(1000)
DECLARE @.PubDate datetime
SET @.sql = N'SELECT ''?'', * FROM articles
WHERE Weight = 3 AND DateInserted >= DATE_SUB(''?'',INTERVAL 15 DAY)'
SET @.sql = REPLACE(@.sql,'?',CONVERT(varchar,getdate(),111)
EXEC(@.sql)
Be absolutely certain that ? is replaced by something you constructed
yourself from a datetime. Do not let the user provide the substitution
string, or you risk SQL Injection from a maliciously-formed replacement
string.
