RE: [MS_AccessPros] Re: Order question in query.

 

Thanks Crystal. From my answers you might think I was paying for messages by the character ;-)

Have an awesome weekend,
Duane

adding on ...

Duane used an alias in the SUBQUERY to differentiate from the group booking table in the main query -- note that when GB is used it refers to subquery and tblGroupBooking refers to the main query source

LEFT(GB.GroupCode,6) = LEFT(tblGroupBooking.GroupCode,6)) AS GroupCheckin
FROM tblGroupBooking;

Hi Kevin

tblGroupBooking GB

can also be written as:

tblGroupBooking As GB

WHERE
GB is an 'alias', nickname, abbreviation, etc -- instead of writing the tablename out each time ...

assume GB is short for GroupBooking ...

warm regards,
crystal

Duane,
What does "GB" mean? Is there any online descriptions about how to use "GB"? Thanks.
Best Regards,
Kevin

Kevin, 
Apparently you want to find the earliest Checkin for the first 6 characters of the GroupCode and use this for sorting the group. 

You can use a subquery like:

SELECT tblGroupBooking.CheckIn, tblGroupBooking.GroupCode, 
(SELECT MIN(Checkin) from tblGroupBooking GB WHERE LEFT(GB.GroupCode,6) = LEFT(tblGroupBooking.GroupCode,6)) AS GroupCheckin
FROM tblGroupBooking;

I don't believe you can sort by the derived column in the query but think this might work to sort a report. If that doesn't work, you could replace the subquery with DMin().

Bill-
This is the result I want:
===tblGroupBooking====
Checkin        GroupCode
2016-May-01    abc001-A
2016-May-05    abc001-B
2016-May-08    abc001-C
2016-May-02    def002
2016-May-03    def003
                       
Best Regrds,
Kevin


Life has an uncanny way of responding to your need.

I'm not understanding what you mean by "they should stick together". The sort order should still work even though the group code is a little longer. 

What results are you getting now and what is your query?

Dear All,

Is the possible to get this done by query?

===tblGroupBooking====
Checkin        GroupCode
2016-May-01    abc001-A
2016-May-05    abc001-B
2016-May-08    abc001-C
2016-May-02    def002
2016-May-03    def003
                       

I want the check in to be the first order, and BroupCode the second order. But If the group code has the same prefix (e.g. abc001), then they should stick to one another. Is that possible? Or is there's any other way to make the outcome look like this? Thanks in advance.

Best Regards,
Kevin
