Sorting in a Report

Experts,

I have a report with a  text Grouping
I need to sort based on my own criteria.  
I can not use the built in sorting.

How can I do this?

Depends on your criteria for sorting :-)


A common approach is to add a "Dummy Column" to your query, with data formatted the way you need it sorted, and then sort on the Dummy Column rather than the raw data.

ok lets say if I have the following:

Won
Lost
Dead
Bid Submitted
Proposal
Possible

Proposal needs to be at the top
Possible second
Won Lost Dead at the bottom and in that order.
mbizupCommented:
Okay - that is a little more complex.

One way to handle that is to have a lookup table for those items... make them selectable from a combo box on your forms.

The table would contain a text field for the selections, and a numeric field (NOT an autonumber) for the sort-order which you define by numbering those items in a lookup table.

Do you currently have a lookup table for this or is the user entering it as free text?

mbizup:  there is no lookup table (its free text).  I am linking to an excel report from a dl from another db and I am making a report based on that data.  

What do you think now?  (might not respond til later in day)
mbizupCommented:
I still would use a table to define the sort order.  Same structure as I described earlier,


If your query looks like this:

SELECT Something, ProposalStatus,SomethingElse
FROM YourTable

Open in new window



Change it to this:

SELECT t1.Something, t1.ProposalStatus, t2.ProposalSortOrder, t1.SomethingElse
FROM YourTable t1 INNER JOIN tblLookupProposalStatus t2 ON t1.ProposalStatus = t2.ProposalStatus
ORDER BY t2.ProposalSortOrder

Open in new window

mbizupCommented:
BTW, You CAN do this with an expression such as an IIF , CHoose, or switch statement or some other variation of that in code in your query -- but those expressions tend to get convoluted.

My own preferred approach is the table method I suggested earlier, which is cleaner and easier to maintain.

That said, The code for a sort order column might look something like this in the query designer (you can extend it as needed)


SortOrder: Switch([ProposalStatus]="Won",1,[ProposalStatus]="Lost",2,[ProposalStatus]="Dead",3 .... etc)

Open in new window

Ahhh... I think I remeber that IIF now.  Will try it later today.  Not at computer now.  Thank you.

changed my mind....doing the lookup table idea

does the t2.ProposalSortOrder (the numeric field) need to be a PK?

If there is a new record in the excel data with a [proposalstatus] not in the lookup table then wouldnt there be an issue if I set ON t1.ProposalStatus = t2.ProposalStatus.  That record in question would not be shown?  

thank you

It can be, but doesn't need to be.  It just should *not* be an autonumber.

With either method, you would have to manually adjust for new proposal statuses (no way around that).  With the table method, you can make it a little easier with a query to detect new statuses and insert them into the table... but you would still have to manually assign a sort order.

This is why I like the table method better.  With the code, you would have to add another criteria to the switch statement -- which can get pretty ugly.

With the table, just add the new status and its numerical order to the table, renumbering the other statuses if needed.

Ok I now see advantages of the table method.  I have made the table and the sort works perfectly as planned.

==>How would an expert do this?   Run the query before the report?
mbizupCommented:
Yea.  Run the query against the spreadsheet data, and update the lookup table so that the sort order is ready for the report.
