Hi,

I have 2 tables and 1 query. Table dbo_RepOrderItem includes columns:

RepId
OrderNumber
Item
ShipDate
SerialCardID

Table tbl_LBP Sales Location Num includes columns:

Location ID
Rep Region Code


What I've been doing so far through my code is working through a query 'CalculateTotal' which looks up a structure number (Which I enter through an InputBox) from table dbo_RoicStructure, gets the SerialCardID from the same table and collects the associated RepId,OrderNumber,ShipDate from table dbo_RepOrderItem and checks that the OrderNumber(s) returned exist in column Location ID in table tbl_LBP Sales Location Num. It also checks that Rep Region Code is not equal to 'INT' nor 'inte'.

My code for all of this works just fine. What I am trying to do now is simplify my results. I want to only return rows that do not have the same Item, OrderNumber, and RepID.

Fore example:

OrderNumber: Item: RepID:
11 3 1
12 3 1
11 4 1
11 3 1
14 7 4
16 8 8

It would now count 5 existing RepID(s) rather than 6 because it would have deleted the duplicated row. This should only be deleted in the user's table not the actual table.

And speaking of the user's table. What I have been doing so far is only returning the results (right now it returns 6, which as I explained above is incorrect) but I also want to return a table or query that would should the user the work behind the returned number.

This is my code:

Thank you in advance :)
 
Is anyone able to help me with this? I would really appreciate it. Thanks.
 
It is not clear what you are asking - if it is just to remove duplicates from appearing in a query then use SELECT DISTINCT or GROUP BY - use the former if you do not need to sum, count, etc.

With regards your second part, please can you rephrase since I do not understand
 
Thank you so much for the reply CJ!!

I will eventually need to count all of the RepID values in that column...and for the duplicate aspect. I should only delete a row if it has the same exact OrderNumber + Item + RepID as another row above it


I've checked with some of my code and there are about 502 duplicate RepID, thing is I can't just assume they have the same OrderNumber and Item. I need a way to check that AND return those updated rows/columns to the user. I don't know how to do that. any ideas?

The code is really long at this point and the only reason for that is because of my attempt at finding duplicates (OrderNumber + Item + RepID rows)...
 
to return only one unique row, just use a group by query

select RO.OrderNumber, RO.Item, RO.RepID
from dbo_RepOrderItem RO
group by RO.OrderNumber, RO.Item, RO.RepID

to return only rows that are not duplicated

select RO.OrderNumber, RO.Item, RO.RepID, count(*) as theCount
from dbo_RepOrderItem RO
group by RO.OrderNumber, RO.Item, RO.RepID
having count(RO.OrderNumber)=1
David
 
aren't both codes doing the same thing? returning unique, non-duplicate rows?

Count is counting the number of rows that are unique? What's the last line of code doing? havingcount(RO.OrderNumber)=1


Thanks a lot David :)
 
Also, how can I view the updated table? The one that is updated after the duplicates are deleted?

Would that table be RepOrderItem? Is there a way to make it visible to the user after the code has gone through and the total calculation has been shown?
 
The SQL I posted will return different number of rows, the first will return a set of distinct values for ALL records, the second which by the way has lost some spaces, should be a space between group by, also
having count(RO.OrderNumber)=1
this will return only rows that have NO duplicates , so in the 6 rows you posted earlier, this sql will return only 4 rows, ignoring the 11 3 1's

This sql will only select rows, to delete duplicate rows is more complex

David


 
Some rows have duplicates. some don't. I want to return both but without the duplicates

for Example:
11,2,5
11,4,7
12,3,9
12,6,8
12,3,9


Should return: 4 not 5 nor 3.

Would the code below accomplish this?

select RO.OrderNumber, RO.Item, RO.RepID
from dbo_RepOrderItem RO
groupby RO.OrderNumber, RO.Item, RO.RepID
