Modules & VBA :: DLookup - Check 2 Criteria In Two Different Columns In Same Table
Dec 2, 2013
I would like to make a DLookup that check 2 criteria in two different columns in the same table. The reason to use a DLookup is that I would like to check if two parts already have been linked together. The user therefore selects two values in to different comboboxes (lstLinkPart and lstLinkToPart). In this case the value of the first combobox is column: ComponentPN in tblProductLinkComponent. For the second (lstLinkToPart) column ProductPN, in the same table, has to be checked.
If both values from the comboboxes match the values in both (and only) columns I don't want to continue and made a code to be executed.
I found multiple examples on the internet for using multiple criteria but something similar to what I require.

I have run into an issue with a basic DLookup. The database has grown in size and now we could have multiple entries, but I want it to return a certain one. So the information could be in it three times. Of course DLookup stops after the first one. How do I get it to loop to check the entire table? Someone mentioned to me to use a recordset, but how to write that as I have never used it before. Below is what I was using until this new request came up.
<code>
Private Sub txtloan1_AfterUpdate()
If IsNull(DLookup("[loan1]", _
"settlement", _
"[loan1]=""" & Me.txtloan1.Text & """ AND [status] = 'Open'")) = False Then
Cancel = True
MsgBox "Test", vbOKOnly, "Warning"
End If
End Sub
</code>
This was also executing after the user entered the information within a text field. I did not want them to enter all the data and then have it come back as a duplicate.

I'm trying to find a code that will allow me to check a value of a yes/no checkbox based on a username.
What I want to happpen is:
1. The code looks to see if the username that is entered in "txtUsername" field on the form matches the "empUsername" value on the table "tblUsers."
2. If there is a match, I want it to look at the value for the field "Admin" on "tblUsers" to see if the value is checked as true.
3. If the value is true, I want it to open a specific form "frmAdmin." If it is false, I want it to open a form "frmMain."
VBA codes not recognizing the Admin field and instead taking all users into the frmMain.

I have a form that has a field that needs to get its data from a query based on two fields in the form. The following is my DLookUp statement:
DLookup("[COMEX]", "OptionMetalsListQ", "[Metals] = '" & [cboMetals].[Column](1) & "'" And "[DateOfPrice] = " & Me.txtDateOfPrice)
Comex is a metal market. the bound column in cboMetals is text and The date is a date.I am getting the error "Run-time error '13': Type Mismatch.

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

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 have this
Code:
If Not IsNull(strCount = DLookup("[Number_Of_Records]", "All_Booked_Callbacks ", "[CallBack_Date] =#" & Me.CB_DAte.Value & "#" _
& " And [CallBack_Time] = #" & Me.CB_Time.Value & "#")) Then strCount = DLookup("[Number_Of_Records]", "All_Booked_Callbacks ", "[CallBack_Date] =#" & Me.CB_DAte.Value & "#" _
& " And [CallBack_Time] = #" & Me.CB_Time.Value & "#") Else strCount = "0"
All_Booked_Callbacks is a query which has a date and time columns and count of callbacks for that day and time, this always returns 0

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 a small problem with dlookup multiple criteria. Vba code looks like this:
Code:
Label34.Caption = DLookup("[Spent_Hours]", "249_1_CHours", "[Date_Added]= " & Me.Text27 & " And [Shift] = '" & Me.Text29 & "'")
This gives following error:
Syntax error in number in query expression '[Date_Added]=4.02.2015 And [Shift] = '2'.
[Shift] column is a numeric field.

having used a query to generate data from a set of records where i can select the criteria (they are two letter abrv and are in a single field in the table but there may be multiple criteria). As I would like others to do it without using the query my first thought was a form with a series of check boxes tick for inclusion in the query or not. As i have built the query am I looking at changing that or taking it all into VB and using some code to pull the relavant 'ticks' across............ and how the hell would i do that......
many thanks in anticipation......

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

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 am having an issue with DLookup, which, for some reason which I do not understand appears to missing the first record in the table.
What I am trying to do is to extract the e-mail address of all users who have 'Admin' status to the database. In the table ('LogIn') there are 3 users who have 'Admin' status and this is confirmed by the DCount function in the following code. There respective ID values in the table are 1, 49 and 51.
Yet when I run the Loop to get all e-mail addresses it misses ID 1 and just returns records for ID 49 and 51.
I have tried changing other users status to 'Admin' and it finds them but always misses the first record.
Here is the code I am using:-
LastIDRef = 0
strToEmail = Null
strMailToAddress = Null
AdminCount = DCount("[ID]", "[LogIn]", "[LogIn].[Security Level] = 'Admin'")
Do
strLinkCriteria = "[LogIn].[Security Level] = 'Admin' And [LogIn].[ID] > " & LastIDRef
[Code] ....

I have 2 tables, one called Addresses and Extended Areas.Within my imported orders I have addresses with postcodes and countries. My Extended Areas table has Country, zip_low, zip_high and extended area with a Y.I wish to check certain postcodes from a particular country between zip_low and zip_high, which gives Y if it is indeed a Extended area.

Front end Access 2010, back-end SQL-server 2008 R2.
Normally I retrieve a certain value by Dlookup("myvalue", "mytable",...)
or
strSQL = "SELECT myvalue FROM mytable...;"
Set rs = CurrentDb.OpenRecordset(strSQL, 4)
But is there any faster way to retrieve a single value from an SQL-server table, beside doing doing the select by a stored procedure running through a pass through query, then open a recordset
Set rs = CurrentDb.OpenRecordset("mypassthroughquery")
just to retrieve ONE value?
I could not find something like DLookup("...) for an SQL-Server or in T-SQL.

I have a lookup which selects a 'Recipient'.
I need to add a check to see if this 'Recipient' (user selected) already exists within another table.
If so, I need a pop-up to appear.
If not, I want the user to continue unimpeded.

I was able to use the UNION ALL qry. But, when I have another file (like original2) that does NOT have all the columns listed in the UNION ALL qry, I get a Parameter value box asking for the missing columns when I run the qry.
Example:
original1IDDateGroupChristianJohnnySteve 18/5/2013A1528/5/2013B338/5/2013C2348/5/2013D2358/5/2013E5
original 2IDDateGroupChristianJohnny18/6/2013A212528/6/2013B2338/6/2013C2248/6/2013D22
The UNION ALL qry includes all the possible resources ( includes all the possible column fields Christan, Johnny, and Steve).
When I run the UNION ALL qry with the original2 file, An "Enter Parameter Value" box is displayed with the mssing column name "Steve".
Is there a way to Map the original2 table into a working table with all the columns, or use VBA code to construct the UNION ALL qry to only include the existing columns? My data has variable columns and I'm trying to avoid the parameter popups.

I have a table that stores ID,PolicyNumber,NewPolNo fields.It has millions of records. The field NewPolNo is empty. I need vba code that will check the following for each record:
1. If the length of the PolicyNumber is over 14 characters long then store that PolicyNumber value in NewPolNo field.
2. If the length of the PolicyNumber is less than 14 characters long thenagain store that PolicyNumber value in NewPolNo field.
3. But if the length of the policyNumber equals to 14 digits long then check the following:
a) If the last 7 digits are 0's of that PolicyNumber. If yes then store first 7 digits in NewPolNo field.
b) If the last 7 digits are not 0's then store the whole PolicyNumber value in NewPolNo field.
We need to check these conditions for each record of the table.

I have a table which contains the following:-
boardingpoint pickupcode pickuptime
bolton N1 07.30
bolton N2 08.00
each boarding point has 6 different pickupcodes and pickuptimes
i am trying to create a form, which is currently displaying data from an query depending on which tour is selected from the main form.
my current dlookup is like this.
=DLookUp("[pickuptime]","boardingpoints","[boardingpoint]=Forms![pickup list]![boardingpoint]")
what do i need to add to the end of this so that it also looks at the pickupcode as well as the boardingpoint to display the correct pickuptime and not just the first one it comes to?

I am designing a project in which there is a form and on that form there is a textbox and Browse button. With browse button you can select a file from the dialog box and that file path will appear in the textbox. This part has been done as below:
Code:
Private Sub CommandButton1_Click()
ChooseFile
End Sub
Sub ChooseFile()
Dim fd As FileDialog
Set fd = Application.FileDialog(msoFileDialogFilePicker)
[Code] ....
Now the next Part i.e Part2 in which we have to see the references present in Column D of the "Summary" worksheet of the workbook whose path is present in textbox1 and check if they match with any of the references in field "Ref" of the Access table named tblLiterature.
If value in column D matches with Ref field of the Access table then change the status field of the Access table to the corresponding columns A,B,C named as "Withdrawn","Obsolete","Updated". that means if the column A of the corresponding Reference is Y then change the status field to "Withdrawn". If column B is Y then change the status to "Obsolete" and if column C is Y then change the status to "Updated".
Please see attached the workbook as this kind of workbook will be searched against Access table .
