Modules & VBA :: Nested DLookup In SQL UPDATE
Jul 31, 2013
I have a nested DLookup in a SQL UPDATE that is not working. The DLookup has an "AND" in the WHERE Statement as well. I cannot figure out the problem. I got a type mismatch with this code and when I take out the single quotes I do not get an error message but the data is not updated in the table.
Code:
SQLstock1 = "UPDATE TBL_STOCK SET Stock = '" & DLookup("RemainingQty", "QRY_STOCK", "ActionEntity = '" & Me.cmb_customer1 & "'" And "StockType = '" & Me.cmb_stock_type1 & "'") & "' WHERE StockEntity = '" & Me.cmb_customer1 & "'"

I have a combo box in a sub form with three values, rate1, rate2, and rate3. I have another three fields in the sub form rate1, rate2, and rate3. The rates are dependent on the item. When I select the rate from the combo box I want a cost field to update on change to the relevant rate. I tried this to no avail:
Code:
txtCost = DLookup(cboRate.Value, "tblItem", "ItemID=" & ItemID)

Ok I'm building a Text Search box that "Live Filters" the results in a ListBox control on the same form.
After typing in a value (Say, for Customer First Name like "Steven") I want the code to do the following:
1. If there is no value in the listbox that matches when the user presses the enter key....open the New Customer form - THIS WORKS
2. If there is a single value in the list, then open this record in the customer form when the user presses the Enter key Receiving a Syntax Missing Operator error on this line:
Code:
DoCmd.OpenForm "frmContacts", , , "[ID]=" & Me.ListCustomers.Column(0)
However, I use this exact code on a button elsewhere in my project (NOT within an IF Function) and it works perfectly fine!
Code:
Private Sub txtSearch_KeyDown(KeyCode As Integer, Shift As Integer)
If KeyCode = vbKeyReturn Then
If Me.ListCustomers.ListCount = 0 Then
CmdNewCustomer_Click
[Code] .....

I am running an export function from a module1 that contains a loop nested within a second loop. Each loop is running through items in a separate combobox on a single form1. The outside loop goes through combo1 items and the inner loop goes through combo2 items.
My issue is that the value of combo1 determines what items are available in combo2 (values are tied to tables). I can get the combo2 values to update when a user changes the values in combo1 (using requery in the afterupdate property of the combo1). However, I do not want a user to change the values, and the code module1 is ignoring the requery. How to force the combobox to requery through code in a module?

I have made this sql statement in VBA where rubriek = a variable but I dont know how to implement a variable in a nested query.
SELECT "rubriek, SUM(verkoopprijs) as prijzen
FROM voorwerp
(inner join VoorwerpInRubriek on voorwerp.voorwerpnummer = VoorwerpInRubriek.voorwerp)
inner join Rubriek on rubriek.rubrieknummer = VoorwerpInRubriek.rubriekOpLaagsteNiveau
where rubriek in (select rubrieknummer
from rubriek
where rubriek = variable name
)
group by rubriek"
Do I have to treat it as a normal select query or is there something speical that I have to do ?

I need to use DMax to open the form on the last record based on the serial number. This code is what I have to open the form currently, but I want only the latest record related to the serial number:
Code:
DoCmd.OpenForm "Form1", , , "incoming_module_sn = '" & Me.txt_sn & "'"
Here is what I tried and it did not work:
Code:
DoCmd.OpenForm "Form1", , , DMax("incoming_module_sn", "tbl_module_repairs", "incoming_module_sn = '" & Me.txt_sn & "'")

How do you write complex nested IF THEN ELSE END IF statements..How do you know what IF statement to put first?Then how would you know where to put ELSE, or END IF?Before you start with the VBA, what are the foundations for making it work successfully, know where you are, know where to put END IF etc?
I've seen many times when using VBA people set up an initial foundation for writing code. For example when needing to put something in quotes, they do "" then enter the text in between, so they don't get errors on running (A very simple, crude example I know, but is there a similar basis for nested IFs).

Hi – I was wondering if anyone knows a solution to this or has had the same thing happen to them in the past…
On one of my forms, I'm using DLookups to fill the controls,
eg.=DLookUp("[PartDescription]","[Parts]","[ItemID] = " & Nz(Forms!ItemHistory!ItemID,0))
This example shows the Part Description for the Item ID in question, with the ItemID being the record source of the form.
Nb. I’m using Lookups since these show info taken from another table to what the main form is based on. I've been advised to keep the main form non-complex so the subform will reference correctly.
This arrangement works fine, except for when the main form changes the record that it displays. In this situation, although the ItemID changes, what the DLookup displays remains the same. I've tried pressing F9 to refresh the lookup, but to no avail.
I was under the impression that the DLookup would automatically update with ItemID – which would seem the logical thing to happen - to me at least. However, I can't figure out why it isn't updating, so any suggestions would be greatly appreciated. Alternatively, if it won't update, are there any alternative ways of going about it (apart from using bound controls)?
Thanks very much in advance,
Tim

I've attached screenshots of the table relationships and some nested forms that I need to discuss in my database.
If you look at the forms screenshot you'll see I have a main form "business/cmc issues" that uses a combo box to select a business name; nested into that I have a second form "policy issues log" that holds details of policy issues about that business; then inside that I have a sub form "issue updates" that records brief details about the actions carried out in trying to resolve each policy issue.
The same policy issue can affect more than one business (because of a relationship between the two companies etc) but still needs to be viewed separately. So for example in the business selector combo box I might have business "ABC". In the policy issue it might say "doesn't pay on time". The "doesn't pay on time" issue might also apply to business "123" and so if I picked that business from the combo box you'd see the same policy issue.
Because it's the same issue for two separate businesses, the actions carried out will be the same, so what I want to do is, after a new action is carried out (where relevant) to be able to click a button that would run some code that copies the actions entered in the sub form for business ABC and pastes them into the sub form for business 123 where the product area and policy issue are equal. This is to avoid having to enter the same data twice.

I need to trigger an event for when a text box is updated.
However, I cantuse on_update() because the text box is updated by dlookup (and on some of my other ones by vb code), and on_update() only works when the user physically enters a value.
Which event should I use. If there isnt one, is there a work around?

I have a new Customer Form(Profile) and I have the same customer data in another Table(Contacts).
I create a Dlookup... the system pull the data correctly from my Combobox but when I try to close the form, the system display a error like: The first name is empty...
I think the Dlookup need something to update the new table.
This's my actual Dlookup...
=DLookUp("[Last Name]","Contacts","[Combo378]='" & [Forms]![PROFILE]![Combo378] & "'")

I'm trying to open a folder based on a BIN nr. This folder could be in a main folder that has diferent subfolder. As there where differnt naming used to create the folderes, one of the things they have always is the BIN nr. It alwasy start with a unique number and maybe I could use it to scan the subfolders and open that one that the BIN nr is equal as in the field BIN.
Now we have serveral 1000th of folders and finding them takes time.

I am trying to dlookup a field (field name [client]) which is on a form (form name bkpo)
The code i use is this
CLNM = DLookup("[ClientName]", "[BKPOCL]", "[ClCode] ='" & [Forms]![BKPO]![Client] & "'")
It works just perfect however if I use the form BKPO as a subform then the code doesn't work
The form is BK1b
and the subform is BKPO
I tryed this but doesn't work
CLNM = DLookup("[ClientName]", "[BKPOCL]", "[ClCode] ='" & [Forms]![BK1b].[BKPO]![Client] & "'")
I have tryed several other options like [Forms]![BK1b]!BKPO.[Client] or [Forms].[BK1b]![BKPO]![Client] but nothing

I am looking to use a "If" statement with DLookup to find a record and see if the field name begins with "TW" as the characters. Here is what I have so far:
Code:
Dim matchCriteria As String
matchCriteria = "LIKE 'TW*'"
If DLookup("end_user", "tbl_module_repairs", "prikey = " & Me.txt_rid1.Value) = matchCriteria Then
MsgBox "Success"
Else
MsgBox "FAILURE"
End If
I am trying to switch between two sets of pricing for customers that begin with "TW" and then all else. Would the use of a "case" statement be better? If so I do not have the "end_user" bound to the form so I would need to embed Dlookup in the "case" method.

I have a command button on a Access 2010 form that i am using as my switchboard. On this form i have a hidden unbound text box that captures the users environ"username". When the user hits a command button on the form the code looks at the name in the hidden textbox that captures the environ"username" and then DLooks up a table to see if there is a match. If yes then it will open the next form and if not then a message box appears.
Code:
Private Sub Command6_Click()
Dim TxtUsername As String
If Me.TxtUsername = DLookup("[OneLondon Login]", "TblAccessUsers") Then
DoCmd.OpenForm "Bakerloo_Main_Form"
Exit Sub
Else
MsgBox "You do not have permission to access this database"
End If
End Sub
This works fine apart from the fact it will only read the first name entered in the table. This table(TblAccessUsers) could have up to 50 names in it and possibly have names removed and re added at a later date. Is there a way i can get the code to look up every name in the table ??

Why does this work when the text box is used and not when the variable is used directly?
Code:
Private Sub Command61_Click()
Dim strDBName As String
strDBName = getDBName()
Me.Text59 = strDBName
Me.Text62 = DLookup("[ModuleName]", "tblModule", "[DatabaseName] = text59")
'Me.Text64 = DLookup("[ModuleName]", "tblModule", "[DatabaseName] = " & strDBName)
'Me.Text64 = DLookup("[ModuleName]", "tblModule", "[DatabaseName] = strDBName")
'Me.Text64 = DLookup("[ModuleName]", "tblModule", "[DatabaseName]" = strDBName)
End Sub
Text62 returns the correct value
Text64 failes on everyone of the examples

At the bottom im printing the content of the controls which are on my form. These should return 1 number, but for some reason it does not. Ive used this code many times but I cant figure out why nothing is being returned.

I'm pretty familiar with getting values from a table via Dlookup. What I want to do is almost the reverse if possible? I'm declaring a variable as follows:
Dim Ref as string
Ref = [lead_id]
This is from a form.What I'd like to be able to do is go to the table [list], reference the lead ID in the table via the variable then change the field [status] to "INCALL".Can this be done in a similar way to Dlookup?
UPDATE - here is the code I am trying to use
Dim ref As String
ref = [lead_id]
Dim MySQL As String
MySQL = "UPDATE vicidial_list SET"
MySQL = MySQL & "vicidial_list.status = 'INCALL' "
MySQL = MySQL & "WHERE (((vicidial_list.status)= Ref))"
DoCmd.RunSQL MySQL
Which gives me an update clause error

a = DLookup("[EUR/TRY]", "Plan_FX_RATES", "YEAR = '" & b & "'")
Debug.Print a
Debug.Print b
Debug.Print RepMonth

At the moment I have a form (InputFrm) for operators to enter production processes into the system. Each one of these has a certain weight which the operators enter and it all stores in InputTbl, which works great.
However I am trying to have a running total of the kilograms inputted on each day displaying when a new record is opened. To do this I have created a query (DailyDataQry) which provides me a running sum of how much input has gone through the process, and I can clearly see the data in this query.
I am attempting to have a text box in the upper right of my form which displays this number as after a certain weight of input the operators are needed to perform checks.
This is the code I have at the moment in the control source of a text box (DailyInputTotalTxt), but it is just returning a blank:
Code:
=DLookUp("[Total Input]","DailyDataQry","[Work Date] = #" & [Forms]![InputFrm]![WorkDateAtxt] & "#")
The work date is generated automatically when the new record is created by having Date() in the default value of the work date (WorkDateAtxt) on the form.
Is there any way which I can use this value to lookup the current total of input contained within DailyDataQry?

I am trying to run this code but getting a run time error 94 - null value - when it shouldn't be.I am thinking I have written the Dlookup incorrectly?
Code:
Private Sub txtProductName_Click()
Dim iProdType As Integer
Dim ProductID As Integer
iProdType = DLookup("ProductTypeID", "tblProduct", "ProductID" = Forms![frmBooking]![cboProductID].[Value])
Note ProductID in an integer
How can I diagnose this or what could the solution be?

I set up an Access 2003 database where this code works OK:
Private Sub Street_Exit(Cancel As Integer)
Me.Suburb = DLookup("Suburb", "Streets", "StreetName = Forms![Add A New Member]!Street")
Me.StreetID = DLookup("ID", "Streets", "StreetName = Forms![Add A New Member]!Street")
Me.Postcode = DLookup("Postcode", "Streets", "StreetName = Forms![Add A New Member]!Street")
Me.Town = DLookup("Town", "Streets", "StreetName = Forms![Add A New Member]!Street")
End Sub
I've now migrated the tables to a back-end in Azure using ODBC to connect. The linked Streets table in my list displays as dbo_Streets but when I change the table name in my code I get an error.

I have the following SQL Statement which returns the desired result to me
Code:
SELECT tbl_p_stats.i_closing
FROM tbl_p_stats
WHERE (((tbl_p_stats.i_weekending)=[forms]![frm_a]![i_olddate]) AND ((tbl_p_stats.i_sacat)=[forms]![frm_a]![wfid1]) AND ((tbl_p_stats.i_complexity)=[forms]![frm_a]![wfc1]));
And am now trying to convert it to a Dlookup to provide the default value to a control on form Loading. The statement i came up with is
Code:
= DLookup("[i_closing]", "tbl_p_stats", "[i_weekending] = " & i_olddate & " AND [i_sacat] = " & wfid1 & " AND [i_complexity] = " & wfc1)
However, it is showing the control (wf1oi) as a blank control now. When I run the dlookup through the immediate window, the returned result is Null.
A little more detail
- All the mentioned controls live on the same form (frm_a)
- The control that this Dlookup is going into is called wf1oi

I need my INSERT statement to DLookup tbl_module_repairs and insert the information from a field based on a WHERE condition of primary key matching on the form and table. Here is what I have but it will not work on the last value:
Code:
Dim lookModType1 As Variant
lookModType1 = DLookup("module_type", "tbl_module_repairs", "prikey = " & Me.txt_prikey1.Value & "")
SQLtext4 = "INSERT INTO TBL_RF_TECH_LOG ([TechID], ActionStatus, Barcode, EquipmentDescription) Values (Left([txt_techid_rework_in], 2),'In Rework', '" & Me.txt_bc1 & "', " & lookModType1 & ");"
DoCmd.RunSQL SQLtext4
Note: My DLookup works fine by itself for other uses.
