I had posted a question last week about about a getting rid of duplicates in a select statement that was answered thanks to people on this forum. After working on it I ran into a problem this weekend.

I have the following SQL statment that returns the correct number of rows



select Distinct CustomerName,CustomerNumber,SalesmanName,Min(ItemDescription) AS ItemDescription,OrigionalDateofService,InsuranceCarrier, Diag1,Diag2,Diag3,Diag4 from O2
Group By
CustomerName,
CustomerNumber,
SalesmanName,
OrigionalDateofService,
InsuranceCarrier,
Diag1,
Diag2,
Diag3,
Diag4

The problem that I run into is that my O2 table also has and ID column, an auto Identity field, that must be included within the result set for development reasons.

When I add the ID to the select statement it returns all the rows of the column. What would be the correct way to include the ID field and get the right set of data.

As auto Identity field is usually unique, you will get all records listed if you include that column in the select statement. If table has 10 rows and the select query returns 4 rows, then how do you expect the value of identity column? Do you want to assign a row number to the result set?
