MS Access Query Concatenate Multiple Row Values Into A Single Row Or Field Used For Many Images For A Single Product

How would I use this in a query?

substitute values into the "test" code till you get what you want. A query can't skip parameters so you would do something like this:

MyCalculatedFieldname: LoopAndCombine("ProductImages", "SkuID", "ProductImageFileNm", Products.skuID, "" , ", " , "No image" , "ProductImageFileNm") 

Select allOpen in new window

Ok I have been trying the module Jim provided and I am having a little trouble. It looks to be the best option for what I am trying to do. But Some Reason it keeps just saying error. Its grouping but in the New field I called ImageList it just says error. This is a single table query

Table name = ProductImages
ProductImageFileNm = Text Field
SkuID = Integer

Select SkuID, DConcat("ProductImageFileNm", "ProductImages", "[SkuID] = '" & SkuID & "'") AS ImageList
FROM ProductImages
GROUP BY SkuID

Select allOpen in new window

Did you put it in a module by itself and name the module something other than DConcat?

Does your app compile?

<<SkuID = Integer>>

   Your treating it as text.  It should be:

Select SkuID, DConcat("ProductImageFileNm", "ProductImages", "[SkuID] = " & [SkuID]) AS ImageList
FROM ProductImages
GROUP BY SkuID

Jim.

Yes that fixed it. Thanks Jim!

OK.... I absolutely knew it was a text integer error and you stated that. But can you please explain exactly what the issue was. I have tried to figure it out and couldn't. Thanks so much.

Oh yeah and by the way I store just the image file name. So how can I concatenate a url on the front of  ProductImageFileNm while using this code? Thanks.

<< But can you please explain exactly what the issue was.>>

When you have a text (string) value, it must be enclosed with ' (apostrophe or what some call a "single quote"), or with " (Quote).

Your original statement had this:

DConcat("ProductImageFileNm", "ProductImages", "[SkuID] = '" & SkuID & "'")

 so you were treating the value of SkuID as a string value.  

Numeric's don't get them, so:

DConcat("ProductImageFileNm", "ProductImages", "[SkuID] = " & SkuID)

Jim.

Ok Thanks but what is a little confusing there is...

"[SkuID] = " has Quotes

I thought quotes treats it like a string?

If so why is it a string but not the other?

Also I don't know if you seen my last comment or not but

"I store just the image file name. So how can I concatenate a url on the front of  ProductImageFileNm while using this code? Thanks."

>"[SkuID] = " has Quotes

quotes make it a LITERAL value -- meaning you need it to say exactly what is in the quoted string

> "I store just the image file name. So how can I concatenate a url on the front of  ProductImageFileNm while using this code? Thanks."

perhaps change DConcat("ProductImageFileNm" ...
to DConcat("ImageURL" & "ProductImageFileNm" ...

WHERE
ImageURL is your fieldname -- change if it is different. Just guessing since his code is a it different than mine.
You may also need to concatenate a slash (delimited with quotes since you need it to say exactly that)  between the URL and filename if the URL if a folder and does not have one on the end.

Oh I see thanks Crystal. I will try that DConcat("ImageURL" & "ProductImageFileNm" later tonight. What I just did was made a query and Concatenated it in that query with a field name Image URL then changed ProductImageFileNm with ImageURL from the new query.

Thank you very much!

you're welcome, Dustin ~ happy to help

my guess is that is how you pass the criteria:

"[SkuID] = " & nz(SkuID,-99)

WHERE
-99 is something you know you don't have

my guess is that is how you pass the criteria:

"[SkuID] = " & nz(SkuID,-99)

WHERE
-99 is something you know you don't have

It works Thanks!
