Modules & VBA :: DLookup Doesn't Return Correct Value
Aug 3, 2015
I'm trying to use a DLookup to get a specific value from a field in a table.
This is what my code currently looks like;
Code:
JOBID = DLookup("[ID]", "MASTER PLANNER", "[JOB NUMBER] = '" & JOB_NUMBER & "'")
Basically I want to get the ID (a number) from a specific record where the JOB NUMBER equals the string I have typed in to a field on the form, also called JOB NUMBER.
However, my problem is that it doesn't navigate to the record where the criteria matches, it just chooses the ID from the very first record of the table.
what I'm doing wrong?

I have a small table, that only contains one record (and should only ever contain one record, which simply gets edited to suit once in a while).The table is called OtherRates, and the fields are as follows:
WRD_Sat/Sun/BH
WRD_Mon-Fri
AHDifferentia
SKDifferentia
Sat/Sun/BH_OTRate
Mon-Fri_OTRate
I am trying to use DLookup to return a value from the relevant field in this table, however the field to look in is a variable.The code (below) that I have tried returns an error and highlights the DLookup line,.
Code:
Dim WRD
Dim DayType
[code]....

I am trying to use a DLookup to search to find what block goes into the production of an item.
In a table called "dbo_vw_MCE_job_with_materials", each item contains a list of the parts which go into its production in a column titled "Expr1". However there are always more than one parts to this, with varying names.
What I am trying to do is to use a Dlookup to only return the first value which starts with B (as the block number is always the only part on the list which begins with B).
At the moment my DLookup would look ike this:
Code:
MixTypeTxt = DLookup("Expr1", "dbo_vw_MCE_job_with_materials", "[item] ='" & Forms![Theta Input]![ItemNumbertxt] & "'")
However I think as the item column contains the same item number in 8 columns, with different values in the Expr1 column, Dlookup only returns the top value "A-CF0057" (which is irrelevant as far as I am concered) - whereas I am hoping it will be able to pull the "B1499" value from the column as it is the only one starting with a B
Is there anyway to specify which value the dlookup function would return, or is there any way to apply some sort of permanent filter on my table?

I have been trying to find a solution to why I can't get a Dlookup with multiple criteria to return the value I need.
Essentially I am trying to use an Order Number to find the item number which is contained within another table. However the order number has multiple lines (suffixes) which alter the item number. Therefore I am trying to have the item number be populated by the correct 'combination' of Order Number and line ("suffix").
I have managed to use the Dlookup in the after update of each box of the form separately and they retrieve values in the table correctly:
Afterupdate of main order number:
Code:
Private Sub OrderNumbertxt_AfterUpdate()
ItemNumbertxt = DLookup("item", "dbo_job", "[job] = '" & Forms![**INPUT]![OrderNumbertxt] & "'")
End Sub
Afterupdate of suffix:
Code:
Private Sub SuffixTxt_AfterUpdate()
ItemNumbertxt = DLookup("item", "dbo_job", "[suffix] = Forms![**INPUT]![SuffixTxt]")
End Sub
However when I combine them as follows in the afterupdate of the Suffix box I receive a "Run-time error '13': Type mismatch"
Code:
Private Sub SuffixTxt_AfterUpdate()
ItemNumbertxt = DLookup("item", "dbo_job", ("[suffix] = Forms![**INPUT]![SuffixTxt]") And ("[job] = '" & Forms![**INPUT]![OrderNumbertxt] & "'"))
End Sub
I think the reason is something to do with some being numbers and some being a combination of text and numbers (based on the replies of other topics), but have been trying to modify these slightly and can't get it to work still.
Also the Order Number is a combination of letters and numbers (normally in the form of AB12345678), the suffix is just a number between 0-9 and the Item number it finds is a combination of numbers and letters.

I am trying to make a DLookup function to return the ID number of an entry that matches 2 or 3 criteria but I am struggling to get the syntax correct for the second and third criteria.
Here is what I have so far:
1 criteria, works fine =DLookUp("[timedata]![id]","timedata", "[processdone] =" & Forms![Mainform]![p11] )
2 criteria, works fine =DLookUp("[timedata]![id]","timedata", "[processdone] = " & Forms![Mainform]![p11] & " And [timedata]![BGSnum] = 1001" )
BGSnum is a numerical value but it changes for each form I load, so what I want to do is use the form location value as the criteria.
E.g.
=DLookUp("[timedata]![id]","timedata", "[processdone] = " & Forms![Mainform]![p11] & " AND [BGSnum] = ' " & Forms![Mainform]![BGS] & "' ')
and possibly a third criteria too. This is where I am having problems and the syntax is wrong so MS Access wont let me save the macro.

I have an old Access 2000 database which needs some functionality update, and I can't get things working as they should.
The issue is related to frmOrderDetails form based on tblOrderDetails table, with following fields:
Order_ID
Product_ID
Ordered_Quantity
Product_Price
For entering ordered products there is a combo box for Product_ID which is displaying information about available products, their stock level, and price.
The Row source for Product_ID looks like this:
Code:
SELECT DISTINCTROW [qryStock4Orders].[Product_ID], [qryStock4Orders].[Product_name], [qryStock4Orders].[Available_quantity], [qryStock4Orders].[Selling_price] FROM qryStock4Orders ORDER BY [qryStock4Orders].[Product_name];
qryStock4Orders holds the calculated values of stock level (Available_quantity) for each product, grouped by Product_ID and Selling_Price. Selling_Price is from tblX.
Because I can buy one product from different suppliers (for different purchase prices) and purchase prices (so selling prices too) of the same product may vary over time, qryStock4Orders may list more then 1 available Selling_Price for that product, for example:
Product_ID Product_name Available_quantity Selling_Price
123 Product xyz 12 25$
123 Product xyz 42 29$
123 Product xyz 8 30$
What I want to achieve is to turn this code placed on After Update event of Product_ID combo box
Code:
Dim strFilter As String
strFilter = "Product_ID = " & Me!Product_ID
Me!Product_Price = DLookup("Selling_Price", "tblX", strFilter)
in something usable, in order to save into tblOrderDetails the selected Selling_Price and not one random Selling_Price from the 3 available above.
As the stock level is updated only after Ordered_Quantity and Product_Price are entered manually, what I'm trying to do with the code above is to automate the data input into Product_Price field of tblOrderDetails.

I've been using the ctrl+F search in order to search my db for a string or phrase (from a form). Now, after I put it on the Intranet and accesss it through there, I use ctrl+F and if I search for something that is not there, it doesn't return a "did not find" box. It's like it just keeps searching.
Is using the find feature like this just bad form and I should write queries for users to search the db?
Comments/critiques/criticisms welcome. Thanks.

I created a database that contains 2 tables. I then created a query that simply groups the data and calculates a row total. And it works as expected. However, when I try to create a report, using the query, I get, "The wizard was unable to generate fields from the record source you chose. Perhaps you chose a query that doesn't return any fields."
What am I doing wrong?
Screencaps attached.
Thanks.

I have lookup table I use to return names for various "Sales Class" codes.It all works good but if there is a code that isn't in the lookup table it leaves that field empty.I want it to return the word "Unknown" for any code that doesn't have a match.Here is the SQL:
Code:
SELECT [Data1].OrderNum, SalesClasses.[Name]
FROM [Data1]
LEFT JOIN SalesClasses ON [Data1].[Sales Class] = SalesClasses.[Code1];
Table examples:
Data1:
OrderNum - Sales Class
111 - class1

basically am creating a booking system, i have a add a room form. my form should check whether i already have a room number in my table, which works when the form is filled in. however when my form is null, then i press add new room button, i get this error rather than " please fill your form in"
Error: runtime error '3075' syntax error (missing operator) in query expression 'Room Number ='.
room number is a number field, integer but has primary key. i cant keep autonumber, as my requirement is to add new room number, but the roomnumber has to be unique.
here is the dlookup;
If DLookup("RoomNumber", "tblRooms", "RoomNumber = " & Forms!RoomPackages!txtRoomNumber) > 0 Then
MsgBox "This number already exists."
Else
p.s it unbound form

I have a field created in a query expression
BirthMon: Format([DOB],"mmmm")
I would like to create another field in the query using DLookup to return the value of the BrithMon.
BrithMonthID=DLookUp("MonID","tblListMons","BirthM on = Mon")
This works good if used with an unbound text box on a form, but when entered into a query expressions, an error is returned: cannot find the name 'BirthMon'
Can I used DLookUp in a Query expression to refer to another Query created field?

I have a simple UDF that takes a string and returns a variant, which is an array of strings Example Input "Brick Wall" Return value would be a variant array with first element "Brick" and and second element "Wall" Now I have a table with a field of strings, and I want to make a query that returns all the results from the function, one per line.
So if my input table looks like this
[strField]
"kick the ball"
"return the pass"
my query result should looks like this
[Orig] [new]
"kick the ball" "kick"
"kick the ball" "the"
"kick the ball" "ball"
"return the pass" "return"
"return the pass" "the"
"return the pass" "pass"
Last time I had to do something like this I used VBA exclusively, with ADO objects, but I thought a query based solution would be easier.
With my current data the largest return array size my function returns is 27 elements but I wouldn't want to rely on that number being fixed.

I have a search from that has an option group, text fields, and a checkbox where the users selects a variety of option that generates a query. If the query return at least on record a split form (form on top/datasheet on bottom) is displayed and the form has an Edit and Close button. If the query returns no records the form is still displayed except the buttons are not visible.
If I knew the result of the query and then made a decision whether to open the form or release control back to the search box that would be great. To open the form I am using VBA with the DoCmd.OpenForm(,,"MyQuery","criteria") command.I thought about using the DLookup command and evaluate the return value for null to be used to control the program flow.

The code I have is.
Code:
Private Sub Command26_Click()
If Forms![test site]![prp test].Form.[A Right Answer] = -1 Then
Forms![test site]![number correct] = Forms![test site]![number correct] + 1
End If
DoCmd.FindNext
End Sub
Then when clicked it checks a yes/no box to see if "A right Answer" is the correct yes. Then it should pop to the main form and take the number correct cell and add one to it. I am trying to get the record to go to the next record inside the sub-form but docmd.findnext seems to be wrong too.

I am using MS Access with SharePoint Lists and some Access Tables to generate reports in pre-formatted MS Excel Worksheets. My main module opens several classes. One of the classes receives a worksheet to keep in a historical book. This class can receive any one of several different types of pre-formatted worksheets. After all is said an done the class adds a cover sheet to the consolidated workbook and adds hyperlinks to the other sheets, kinda like a table of content.In the class I have the following in the general declaration.
code:
Public Enum BookType
A = 1
B = 2
End Enum
Private pBookType As BookType
Later in the class I have the following:
Code:
Public Property Let LoadBookType(ByVal btNewValue As BookType)
pBookType = btNewValue
AddWorkBook
End Property
in the main modual I have the following
Code:
classConsolidated.LoadBookType = A
When assigning the above property it passes in "11"
if I change it to the following
Code:
classConsolidated.LoadBookType = BookType.A
it passes in "1" as I expect and use in a Select Case statement later in the class.So why does one pass in "11" but the other passes in "1"?

I'm trying to pass some dates from an excel userform into access.
The date is chosen using the DTPicker tool ( basically a drop down calender). I have set the property of this to custom format dd/MM/yyyy, however dates get passed to the appropriate field in access in the American format.
In access the date fields are set to Short Date and the example shown for this format is in the UK format. I assign the date to a variable before passing that variable to the update SQL string:
Code:
s1 = Nz(DTPicker1.Value, #1/1/2000#)
I have dimmed s1 as date and then added:
Code:
s1 = Format(Date, "dd/MM/yyyy")
My update string is:
Code:
"SET [Stage 1] = " & "#" & s1 & "#" & " "
I suspect that the nozero function may be the issue but am at a bit of loss atm.

I am trying to load a form based on an if statement. I think my issue is that I have the DB set to Display form "frmSplash" on open. I have tried the following (frmSplash form load event) but it continues past the frmMenu and stops at the frmSplash. I want to open the DB and look to see if it is registered and if yes then open frmMenu. There is 1 record in tblRegistration so it should open to frmMenu. I checked and it is seeing the 1 record.
Code:
Private Sub Form_Load()
Dim rs As Recordset
Set rs = CurrentDb.OpenRecordset("SELECT * FROM [tblRegistration]")
If rs.RecordCount > 0 Then
[code]...
Does the display form on open override all? how to achieve to goal?

I am having trouble with the below returning the correct number of records, and can't see why.
I have one table, tblDevice, which has 4 columns, ID | DeviceRecNo | ExcludeFromCheck | StockLocationID
ID - Autonumber
DeviceRecNo - Number
ExcludeFromCheck - Number (1 = yes, 0 - No)
StockLocationID - Number
I have the following running as part of some code, but it is not returning the correct number of records, and I cant see why not. I have tried creating this in a query in Access itself, and copy the SQL into VBA and it still doesn't return the correct number records.
I have 4 records in there for testing, all with StockLocationID = 3, all with different DeviceRecNo, and two each of ExcludeFromCheck, 2x0 and 2x1
Code:
Public Function test()
Dim db As dao.Database
Dim rs1 As dao.Recordset
Set db = CurrentDb
Set rs1 = db.OpenRecordset("SELECT DeviceRecNo FROM tblDevice WHERE StockLocationID = 3 AND ExcludeFromCheck = 'No'")
Debug.Print rs1.RecordCount
End Function

I have code attached to a command button to fill a Combo Box with data from a music collection. A letter of the alphabet is entered into a Text Box then records beginning with that letter are copied from a table, either by Artist or Title. They are saved to a temporary table at which time they are in no particular order. Those records are copied to a further table and saved in alphabetical order. This table is then used to fill the Combo Box.
I used two temporary tables because the records were not displayed in the correct order. I hoped this might cure it, it did not. The records are in order in the table but not in the Combo Box.
Code:
Private Sub Command68_Click()
'SEARCH AND FILL COMBO BOX

Staff are monitored to make sure they are keeping up to date with our customers. A customer can have multiple projects going through the factory at any one time. Each customer has a record per project and a 'general' record. Ideally we would like our staff to be able to move the 'general' record when they update a project record as opposed to either having to find and then update the general record after, or forgetting and calling the customer again 2 days later!
Including a msgbox for the EnqNum seems to show the general record correctly, however being new to access I am unsure if I have the update part correct.
Code:
If Me.chkMoveGen.Value = "-1" Then
Dim EnqNum As Integer
EnqNum = DLookup("[e_id]", "tblEnquiries", "[c_id]=" & Me.txtc_id & " and [e_status] = " & "13")
DoCmd.RunSQL "UPDATE tblEnquiries " & _
" SET e_date_due=#" & Format(Me.txte_date_due, "MM/DD/YYYY") & "#" & _
" WHERE e_id= EnqNum"

I've been trying to work up a where clause that is generated by a button click event on a report. The workflow that i'm trying to obtain is as follows:
1) A report is run to determine the remaining work orders that need to be processed.
2) A button that is placed on that report is to be clicked, taking the user to the form associated with that work order, so it can be processed.
What i've been able to do so far is capture the unique ID for the work order and then print that in a message box. I can then open the form.
What i haven't been able to accomplish thus far is to open the form to the correct work order.
Things I've tried : I started trying to use the macro with the search for record option and using the where clause. Not successful. I am a little more comfortable in using vba so i switched to that pretty quickly.
Code:
Private Sub btnJobEntry_Click()
'GOAL: open the work order form to the correct entry
'METHOD: store the uniqueID to a variable, then use that in the open command's where clause
Dim strJobID As String
'store the unique ID in the variable
[Code] ....
I've put the strJobID variable in both the filter and where clause sections of the DoCmd but it just opens the form to the first entry. I'm fairly confident i'm not applying the filter/where clause correctly by using the incorrect syntax.
