DataAssist returning duplicate results

DataAssist returning duplicate results

I'm using DataAssist search on the home page and also the results page. Both return results multiple times.

For example, if Products A and B are returned in the results, it will list both in correct order, but repeat that order as many as 10 times.

Also, Product images are showing as question marks from the home page search, but correctly in the results page search.

Can I get a url to view the problem and a copy of the pages you are working with? I'll need to look at them to debug what is going on.

Please attach a copy of the pages you are working with as well so I can look at the code.

Also what are you typing into the search fields? Please give me precise steps to reproduce the issue you are experiencing.

Home page search:
It returns the correct product results, but also multiples of the search result.

Enter product number 2010, it returns the same product 19 times.
Enter 201 it returns product numbers 201 and 2010 correctly. It also repeats these two multiple times
This also happens with text entries

Results page search:
Doesn't return correct search results. Enter any value, it returns the entire Db multiple times.

Files attached.

This is an issue with your SQL statement:
SELECT * FROM Prod INNER JOIN ProdType ON ProdType.TypeID = Prod.ProdType INNER JOIN ContSize

If you do an inner join with another table that has multiple results, then the recordset will return a row for each result.

You can fix that by adding a GROUP BY statement to the SQL like:
SELECT * FROM Prod INNER JOIN ProdType ON ProdType.TypeID = Prod.ProdType INNER JOIN ContSize GROUP BY ProductID

Which will then only show one row for each unique ProductID, or you could use a distinct clause like:
SELECT DISTINCT Prod.* FROM Prod INNER JOIN ProdType ON ProdType.TypeID = Prod.ProdType INNER JOIN ContSize

You will still want to add an ON clause for your ContSize join because the query as it stands makes no sense.
