your dcno=@dcno is does not match. so try to equal value.

You do have order by so if it is not coming out the way you want there must be some other issue.

Psst! Look at the column names he is using... :laugh:

ZurdoDev 23-Dec-13 11:22am

Ya, but he wanted it that way. At least that is how I read it.

OriginalGriff 23-Dec-13 11:50am

Well, it is what he *asked* for! :laugh:
Not necessarily what he *wanted*.
A bit like christmas presents, I think ;)

Um.
Are you sure? CONVERT(VARCHAR,column, 103) converts a DateTime to a specific format string...doesn't it? He then masks the original DateTime value with the string version with the AS I think.

You are correct. Thanks for the review and comment.

Um.
It is, you know...it's sorted exactly as you specified.
When you select this:

SQL

select
    liftingbirds, totalweight, avgweight, dcno,
    convert(varchar,liftingdate,103) as liftingdate

You are creating a new temporary Text based "column" called "liftingdate", which masks the original DateTime based version.
So when you do this:

SQL

order by
    liftingdate desc

You are specifying that the records should be returned in order of the new text "column" - and the sort is a text sort (character by character) as a result.
Try:

SQL

select
    liftingbirds, totalweight, avgweight, dcno,
    convert(varchar,liftingdate,103) as [lifting date]
from
    k_LiftingEntryRecords
where
    dcno = @dcno
order by
    liftingdate desc
