I have the following SQL Statement:
SELECT StockChild.ProductId, Sum(StockChild.Qty) AS SumOfQty,
PRODUCTDETAILS.Title, Sum(SALESORDERchild.Stockout) AS SumOfStockout
FROM (PRODUCTDETAILS
INNER JOIN SALESORDERchild
ON PRODUCTDETAILS.productID = SALESORDERchild.ProductId)
INNER JOIN StockChild
ON PRODUCTDETAILS.productID = StockChild.ProductID
WHERE (((StockChild.ProductID)=[Forms]![StockChild]![ProductId])
AND ((SALESORDERchild.ProductID)=[Forms]![StockChild]![ProductId]))
GROUP BY StockChild.ProductId, PRODUCTDETAILS.Title;
I'm trying to get the summation of values from 2 different tables using the above SQL Statement in access:
1) Sum of StockChild quantity based on productID
2) Sum of Salesorderchild Stockout based on productID
If i query it separately, i managed to get the values that i needed but i'm unable to put it into a single form.
but when i query it together as above, the values jump all over the place and i can't seem to understand why.
And if i add another record in the salesorderchild, of the already existing isbn, all the values will jump as well.
is there something that i am doing wrongly? or how should i go about to tackle this matter.
I added some explanations in the image attached.
Update:
I was trying another method whereby i just did a normal query for the initial stock to be displayed(which worked fine getting the numbers i need)
and over in the Total stockout i was trying out a
=DSum("[stockout]","[SALESORDERchild]","[ProductId]=" & [Forms]!
[StockChild]![ProductId])
but it was returning me a #Name? did i use this correctly?, should i do a vba code instead or is there a way to do it this way?
i tried the following vba code function as an alternative to select out the value but it was telling me the user-defined type not defined. am i missing out something? - (fixed this part by defining the reference of active x data object)
Private Sub Form_Current()
Dim intI As Integer
Dim fld As Field
Dim rst As ADODB.Recordset
Dim pid As String
pid = ProductID.Value
Set rst = New ADODB.Recordset
rst.Open "SELECT Sum(SALESORDERchild.Stockout) AS SumOfStockout FROM
SALESORDERchild WHERE SALESORDERchild.ProductID ='" & pid & "';",
CurrentProject.Connection, adOpenKeyset, adLockOptimistic
tb_stockout.Value = rst.Fields("SumOfStockout")
End Sub
Done Thanks everyone :)

I'm currently working on a project and I've been having trouble trying to get a function that is able to return the value of a query, which I do need in order to display it on a textbox.
The current code is like this:
Public Function rubrieknaamSQL() As String
Dim rst As DAO.Recordset
Dim strSQL As String
strSQL = "SELECT T_Train.trainPlate, T_Category.categoryName FROM T_Category INNER JOIN T_Train ON T_Category.id = T_Train.category_id WHERE (((T_Train.trainPlate)=[Forms]![F_Comboio]![Combo_Search_Comboio]));"
Set rst = CurrentDb.OpenRecordset(strSQL)
rubrieknaamSQL = rst!categoryName
rst.Close
End Function
I should say that the code is copied from other publisher and I do not own its rights. However, it still won't work when I try to run it and the error displayed goes like this:
Run-Time Error 3061 : Too few parameters. Expected 1
and it happens in Set rst command.
For a SELECT query to set a recordset object, concatenate variable:
" ... WHERE T_Train.trainPlate=" & [Forms]![F_Comboio]![Combo_Search_Comboio]
If trainPlate is a text field, need apostrophe delimiters (date/time field needs # delimiter):
" ... WHERE T_Train.trainPlate='" & [Forms]![F_Comboio]![Combo_Search_Comboio] & "'"
For more info about parameters in Access SQL constructed in VBA, review How do I use parameters in VBA in the different contexts in Microsoft Access?
There are ways to pull this single value without VBA.
make combobox RowSource an SQL that joins tables and textbox simply references combobox column by its index - index is 0 based so if categoryName field is in third column, its index is 2: =[Combo_Search_Comboio].Column(2)
include T_Category in form RecordSource and bind textbox to categoryName - set as Locked Yes and TabStop No
build a query object that joins tables without filter criteria and use DLookup() expression in textbox
=DLookup("categoryName", "queryname", "trainPlate='" & [Combo_Search_Comboio] & "'")
I have a order creation form in an Access database where the user selects a product and VBA code is triggered with SQL select statement to retrieve the current availability of that product. This is how it's set up:
I have a Packages table where products batches are added to inventory.
I have an OrderDetail table where items from product batches are allocated to orders.
I have a InventoryPrep query with a the total packaged per batch and field that sums the number of allocated products per batch from the OrderDetail table.
Then I have an Inventory query that that has a calculated field that takes the TotalPackaged field from the InventoryPrep query and subtracts the TotalAllocated field from the InventoryPrep query.
Here is the VBA code in my form, triggered by an update to the [Batch] combo box:
Dim VBatch As String
VBatch = Me.Batch.Value
Dim VAvail As Double
Dim mySQL As String
Dim conn1 As ADODB.Connection
Set conn1 = CurrentProject.Connection
Dim rs1 As New ADODB.Recordset
rs1.ActiveConnection = conn1
mySQL = "SELECT Available FROM Inventory WHERE BatchID = " & "'" & VBatch & "'"
rs1.Open mySQL
rs1.MoveFirst
VAvail = rs1.Fields("Available").Value
Forms!ChangeOrders.ChangeOrderSubform.Form.Availability.Value = VAvail
rs1.Close
conn1.Close
Set rs1 = Nothing
Set conn1 = Nothing
This has been working just fine for weeks, retreiving the correct available amount as packaged items are added to the Packages table and orders are being added in the OrderDetail table. Yesterday it started returning the Packaged field from the InventoryPrep query instead.
I tried a bunch of things and then created a table from the query and used the SELECT statement to look it up in the table. That worked. There is something about my query set up that has caused it to stop recognizing my calculated field. I need help!
This is my first time posting and I hope this is enough information. I'm pretty new to Access and VBA but I've learned a lot from reading in this forum. I hope someone can help or let me know what other information could shed light on the problem.
To read a single value from a table or query, your code is a bit over the top.
For this scenario, Access has the DLookup function.
VAvail = DLookup("Available", "Inventory", "BatchID = '" & VBatch & "'")
Forms!ChangeOrders.ChangeOrderSubform.Form.Availability.Value = VAvail
That's all that is needed.
Hello Stackoverflow community!
My question is in reguards to creating a custom column within a list box that is pulling from a table using SQL. Refering to the code and picture of the current list below, I want to create a custom column that is not stored in a table, that will be called "DaysActive" and will take todays date minus the StatusEffect Date for each individual record displayed and give the number of days in its own column, say between StatusEffect and Yr. Is this possible? Thank you in advance for taking the time to read through this.
Private Sub Form_Load()
DoCmd.RunCommand acCmdWindowHide
Dim rs As Recordset
Dim strSQL As String
Dim lstnum
strSQL = "SELECT LastName, FirstName, Status, StatusEffect, Yr, Make, Model, VIN, Deduction, USLicense, RegistrationState, Dependents,Notes, ID FROM InsuranceTable" & _
"WHERE SentRegistration = False And Status IN ('active','add') Order By StatusEffect Desc "
Set rs = CurrentDb.OpenRecordset(strSQL, dbOpenSnapshot)
Set Me.lstInfo.Recordset = rs
lstnum = [lstInfo].[ListCount]
Me.lstcount.Value = lstnum - 1
End Sub
Link to picture of my current list since I do not have enough rep points to embed it ;/
Use the DateDiff() function in your SQL.
DateDiff('d') returns the difference in days.
SELECT ..., StatusEffect, DateDiff('d',[StatusEffect],Date()) AS DaysActive, Yr, ...
can this be done, say I have rows (1,2,3,4,5) and I want to grab three rows, select one randomly and then get it's neighbors, so maybe the random selection is row (3), I can also grab (2,4) if I wanted its neighbors, do I just pick one at random and then look for the unique key before and after like this or can I do it all in one sql statement.
I was going to use ADO from excel to pull records (so VBA connects to access, opens a recordset with sql instructions and so on).
Hope I was clear!
I would love to just do this all in a SQL statement
I am not sure Access is capable of all the SQL commands such as SQL Server, so this may be a bit of a problem. If you have a primary key though, you can easly generate a Select query in VBA and then pass open recordset with this SQL.
Dim sSQL as String
Dim lRand as Long
Dim rs as ADODB.Recordset 'or DAO.Recordset'
lRand = VBA.Int(VBA.Rnd() * TableRecordCount) ' TableRecordCount is the number of records in the table that you need to get somehow'
sSQL = "SELECT * FROM TableName WHERE (ID>=" & lRand - 1 & " AND ID <=" & lRand + 1
set rs = CurrentDB.OpenRecordset(sSQL, ...)
I am now not absolutely sure of what you want to use and depending on ADODB or DAO choice, you need to open the recordset accordingly with wither Call rs.Open or Set rs = DB.OpenRecordset
I am trying to create a recordset in Access VBA that will show me all records in a table related to the current record of a form. My current code looks like this:
Private Sub Form_Load()
Dim rst As Recordset
Set rst = CurrentDb.OpenRecordset("Select [ID], [Ln] From [Order Detail] Where ((([Order Detail].[ID]) = [Forms]![Order Data Entry Header]![ID]))")
rst.MoveLast
Forms![Order Data Entry Header].LineNum = rst![Ln]
End Sub
I am doing this so that when adding new records they can be numbered sequentially after the highest number. When I run the form it get "Run-time Error: '3061' Too few parameters. Expected 1." on the Set rst line.
Any help would be appreciated.
The issue is the fact that the string you see there is exactly what is getting passed to the driver.
You need to "build up" the string, like so:
Set rst = CurrentDb.OpenRecordset("Select [ID], [Ln] From [Order Detail] Where ((([Order Detail].[ID]) = " & [Forms]![Order Data Entry Header]![ID] & "))")
Watch to make sure that [Forms]![Order Data Entry Header]![ID] is safe content, since you are building up an SQL statement.
