View 5 RepliesI am working on a database with about twenty tables. In one of the tables "Customers" their is a column with
a primary key. Call it "CustomerNumber".
The problem is that we log customers from multiple vendors and so we might have the same customer number, but from different vendors. So really this would be a perfect situation where we could set up the primary key to be a composite key consisting of the Vendor and CustomerNumber combination.
The integrity of the database is not very well maintained because the Primary Key CustomerId is never used as a secondary key in any of the other tables.
So here is my question. Instead of making a primary composite key, can I just drop the primary key all together?
This is one of those questions I really hate to ask, because typically I would never lean tword this drastic of a measure to solve a problem. Because of other situations I can't discuss this might be the best alternative. So would it be okay to drop the primary key constraint all together?
control duplicate primary key.

View 3 RepliesI am having trouble with duplicate records. I tested .distinct() in several areas and nothing helps.
I got the search criteria from the PreviousPage. I then used this criteria to search QueryA.
I did a search using QueryA. I took the results, and put the IDs into an array.
I then did a search using QueryB, that matched the IDs in the array. QueryB is used for the ListView and to page records.
Using test records. QueryA results = 2 records. The array.length = 2. QueryB results = 3. ?
What am I doing wrong ?
Some of my Code:
myResults = (from r in QueryA
select r.ID).Distinct().ToArray();
totalrecords = myResults.Length; // = 2
