In Access 2003 I am creating an Inventory Database from scratch. There are two tables (tblProductInfo rmation and tblSubProducts) that I am trying to use in a queary to determine the number of Items in Stock. The SubProducts table is linked to the Product Information table by Item # (and the information is added and viewed as a form Product Information with a Sub Form Sub Products)
I have a form (frmInventoryLo cation) where a location is selected for the Queary, the queary also has criteria to return all locations if no location is choosen.
There is a calculation field in the queary that I am using to calculate the number in stock by subtracting the # Sold from the # recieved (both fields in the SubProducts table). This calculation works fine. However, I want to limit my list to those enteries that have inventory in stock (AKA In Stock > 0) I have tried adding the >0 criteria to the calculated field but the queary still returns all results, even those with no stock.
I have managed to get around this by creating a second queary (QryInventoryLo cation) that has all the fields from the first queary (QryInventory) and the Criteria of >0 for the In Stock field. This works but requires that I have two quearys to do something that I think I should be able to accomplish in one. Does anyone have any ideas to fix my first queary to 'see' the >0 criteria?

How about pasting in the SQL for your query? Please wrap it in the code tags by selecting the text and then clicking the # button on the top of this reply window. You can also manually edit the first tag to look just like this: [code=sql]

Scott,
Thanks for your reply to this question...belo w I have copied and pasted the SQL view of my queary and I have used the # symbol to format the code as you requested. Please let me know if you need anything else to evaluate this issue. Thanks again for your help!! - SELECT tblSubformProducts.EventLocation, tblProductInformation.VendorCode, tblProductInformation.[Item#], tblProductInformation.Description, tblProductInformation.Category, tblProductInformation.SubCategory, tblProductInformation.Discontinued, Sum(tblSubformProducts.[# Recieved]) AS [SumOf# Recieved], Sum(tblSubformProducts.[# Sold]) AS [SumOf# Sold], Sum(tblSubformProducts![# Recieved]-tblSubformProducts![# Sold]) AS [On Hand]
-
FROM tblProductInformation INNER JOIN tblSubformProducts ON (tblProductInformation.[Item#] = tblSubformProducts.[Item #]) AND (tblProductInformation.[Item#] = tblSubformProducts.[Item #]) AND (tblProductInformation.[Item#] = tblSubformProducts.[Item #])
-
GROUP BY tblSubformProducts.EventLocation, tblProductInformation.VendorCode, tblProductInformation.[Item#], tblProductInformation.Description, tblProductInformation.Category, tblProductInformation.SubCategory, tblProductInformation.Discontinued
-
HAVING (((tblSubformProducts.EventLocation)=[Forms]![FrmInventoryLocation]![Text37]) AND ((Sum([tblSubformProducts]![# Recieved]-[tblSubformProducts]![# Sold]))>0)) OR ((([Forms]![FrmInventoryLocation]![Text37]) Is Null))
-
ORDER BY tblSubformProducts.EventLocation;

For your calculated field, place it within an IIf statement: i.e. iif([tblSubformProdu cts]![# Recieved] => [tblSubformProdu cts]![# Sold], Sum([tblSubformProdu cts]![# Recieved] - [tblSubformProdu cts]![# Sold], "")

Scott,
I went back to my queary and inserted the text at the point I thought it should go and when I tried to save the changes I got the following error message:
Sintax error (missing operator) in queary expression '(((tblSubformP roducts.EventLo cation)=[Forms][FrmInventoryLoc ation]![text37]) AND (iif([tblSubformProdu cts]![#Recieved]=>[tblSubformProdu cts]![#Sold], SUM ([tblSubformProdu cts]![#Recieved]-[tblSubformProdu cts![#Sold], "") Or ((([Forms]!FrmInventoryLo ca'.
When I click OK it returns me to the code and the > symbol is highlighted.
I have very little knowledge of how SQL works and appreciate your continuing help with this issue.

The SQL should replace the calculated field, not be used as a WHERE criteria. In other words, if you go into the query design view and look at the Fields grid, add one that looks like this: - In Stock: IIf([tblSubformProducts]![#Recieved]... etc etc.
(obviously you'll need to retype the etc etc part :-)
Regards,
Scott
OK, I am now working in the right area anyway, I have removed my previous calculation field and have replaced it with:
In Stock: IIf([tblSubformProdu cts]![#Recieved] => [tblSubformProdu cts]![#Sold], Sum([tblSubformProdu cts]![#Recieved]-[tblSubformProdu cts]![#Sold], "")
When I try to run the queary there is an error message:
The expression you entered contains invalid syntax. You may have entered a comma without a preceding value or identifier.
When I click OK the > symbol is highlighted.
I really appreciate your continued help!
My most humble apologies! I mistyped the greater-than-or-equal-to comparison operator ;-(
It is actually >=.
Regards,
Scott
Scott,
Thank you for your continued patients with me. I have made the change from => to >= in my queary and now I get a new error message.
You tried to execute a queary that does not include the specified expression 'IIf(that line of text we've been working with)Sold], "")' as part of an aggregate function.
When I click on OK there is a curser in the table field of my grid under the calculation expression. Again, I am at a loss as to how to correct this error.
On a side note, your last post commented on the greater-than-or-equal-to comparison. If this translates the same in access as I remember it translating in math than the # recieved can be the same as the # sold, and when we subtract them from each other we would get 0 in stock. I am trying to eliminate the locations with 0 in stock from the queary, so is this the function that we want?
Again, thank you for your continued help with this issue. I really appreciate your assistance.
Not a problem... If you wish to eliminate the 0 results, then you can just change the >= to > (greater than). Putting your IIf() statement inside the Sum() function in that same field should resolve the next error message (instead of having the calculation performed inside the IIf). In Stock: Sum(IIf([tblSubformProdu cts]![#Recieved] > [tblSubformProdu cts]![#Sold], [tblSubformProdu cts]![#Recieved]-[tblSubformProdu cts]![#Sold], ""))

Scott
