bit of a Friday moment with some SQL

Christopher Hill

Hia all

 

I am having a bit of a Friday moment with some SQL and am hoping someone can show me the light…??

I am sure its very basic – but the finer details are some what eluding me today…

 

I have this script equivalent…

 

            Select

                        B.Description

                        Count(B.Description)

                        Sum(A.Amount)

            From

                        Table1 A

                        Join Table2 B on (A.id = B.id)

 

Where table A has one to many records of table B.

 

This runs fine, but what I am seeing is an incorrect Sum amount due to this one to many association between the two tables.

i.e. if an ID from Table A has £5 in the Amount column, and the same ID exists on 4 records on Table B – my sum result is coming back at £20, I only want a distinct £5.

 

My initial thought was to do something like putting Distinct in front of the A.Amount (Sum(Distinct A.Amount)) within the aggregate, but this groups by the money values, and not the ID…

 

I hope that makes sense to someone out there?!

Many thanks in advance!!

    Does anyone know what item in security controls the ability to view/close other user’s batches?  We have a ticket office assistant that cannot see all users batches, but other ticket office people can and we cannot tell where the difference is in security/permissions.

     

    Thanks in advance,
