I'm trying to write an If statement that determines if my column [Pack_Number] has only one Unique number or if there is more than one.
I'm not exactly sure of the syntax to make this check for an Access Table since it uses records instead of rows like Excel.
This isn't right but it shows what I'm trying to do:
If [Forms]![ReviewButton]![RetailEntry].[Form]![Pack_Number].Value = Distinct Then
MsgBox "It's Unique!"
Else
MsgBox "It's NOT Unique!"
End If
Can anyone point me in the right direction for this check or have an example they can show me?
Any help would be greatly appreciated!
Thanks!
Consider domain aggregate, DCount, to search on specific value. Below assumes form value is a string to encloses single quotes.
If DCount("Pack_Number", "myTable", _ "Pack_Number = '" & _
[Forms]![ReviewButton]![RetailEntry].[Form]![Pack_Number].Value & "'") = 1 Then
...
Per #Erik's comment, no need to concatenate or punctuate:
If DCount("Pack_Number", "myTable", _
"Pack_Number = [Forms]![ReviewButton]![RetailEntry].[Form]![Pack_Number].Value") = 1 Then

I am trying to count the number of records in a table which satisfy criteria for two different fields. Both fields are string values.
The first field is what type of Test appears e.g. 'Manometry'. I can get this field to work on it's own.
I experience a problem when trying to add the second criteria.
The second field is the TestID, which is in the format A_155_19, where 155 is the investigation number and 19 identifies the year it took place.
I would like to count all the manometry tests which occur in the current year.
DCount("[Test]", "Visits", "[Test] = 'Manometry'" & "[TestID] = *Right((Year(Date)), 2)'")
I am currently getting the error message 3075, which is missing syntax.
Any help would be greatly appreciated.
What about:
DCount("[Test]", "Visits", "[Test] = 'Manometry' And [TestID] Like " & SomeExpression)
You can use Format:
DCount("*", "Visits", "[Test] = 'Manometry' And [TestID] Like '*_' & Format(Date(), "yy") & "'")
I am working on a form that is meant to analyze financial data ahead of an insurance policy renewal. It needs to pull various premium and claim $$ totals from the tables, and insert them into the form. From there, it will run some calculations with them, but that should be the easy part. Where I'm struggling is the SQL statements to get the data, in the first place.
After narrowing it down a bit, I've found that the problem is the code is putting the SQL statement into the field on the form, instead of the answer the SQL statement should be providing. I have tried multiple things I've seen online, and can't figure out how to resolve this.
One of the SQL statements reads like this:
L12W = "SELECT Sum(tblActPrem.APWrit) AS SumOfAPWrit FROM tblActPrem " _
& " WHERE tblActPrem.EntID = '" & Me.ctlActEntID & "' " _
& " AND tblActPrem.PolNum = '" & Me.ctltblRnwlTrack_PolNum & "'" _
& " AND tblActPrem.APDate BETWEEN #" & L12M & "# AND #" & Me.ctlRnwAnalysisDt & "#;"""
It should be totalling premium data from the table, where the policy number and account number match what's on the form, and between the selected dates, and putting that total into the field on the form. Instead, I get this on the form:
SELECT Sum(tblActPrem.APWrit) AS SumOfAPWrit FROM tblActPrem WHERE tblActPrem.EntID = '1235' AND tblActPrem.PolNum = 'Policy1' AND tblActPrem.APDate BETWEEN #1/1/2014# AND #1/1/2015#;"
That is exactly how the statement should be running, but can anyone tell me how to make the leap from the statement, to the data?
Thank you!
Consider using DLookup or DSum in the control source of the form's field.
DLookup Solution
First, change your VBA SQL query into a stored SQL Query (notice quotes and # symbols are not necessary when referencing form controls):
SELECT Sum(tblActPrem.APWrit) AS SumOfAPWrit
FROM tblActPrem
WHERE tblActPrem.EntID = Forms!<yourformname>!ctlActEntID
AND tblActPrem.PolNum = Forms!<yourformname>!ctltblRnwlTrack_PolNum
AND tblActPrem.APDate BETWEEN Forms!<yourformname>!L12M
AND Forms!<yourformname>!ctlRnwAnalysisDt
And then in the form field textbox's control source use the DLookUp function (no criteria argument is needed since this should return only one value).
= DLookUp("SumOfAPWrit", "<yournewqueryname>")
DSum Solution
Alternatively, you can change the entire SQL statement into a DSum but notice how long the criteria (WHERE statement) would have to be.
= DSum("APWrit", "tblActPrem", "EntID = Forms!<yourformname>!ctlActEntID
AND PolNum = Forms!<yourformname>!ctltblRnwlTrack_PolNum
AND APDate BETWEEN Forms!<yourformname>!L12M AND Forms!<yourformname>!ctlRnwAnalysisDt")
Sorry if the title is confusing. But I have a table with a few different columns. One column is the KitNumber and the other is the ReturnDate. I am trying to select the value of the ReturnDate to see what the length of the entry is (also, does VBA let you get the length of a date?). What I need to do though, is the user will enter a number in an unbound, and then that value will look in the table to see if it matches another value in there, and if it does, it will select the return date. Here is the code I have now:
strSQL = "SELECT ReturnDate FROM Crew WHERE KitNumber = " & Me.AssignKit
Debug.Print strSQL
DateLen = Len(strSQL)
So say I enter '111111' in the unbound. I want it to look in the table then to see if there is a matching number. Then if there is it should return the ReturnDate value and get the length of it. Cause right now the Debug just returns the KitNumber instead of the date. Anyone be able to help me out? Thank you
If it's a one off, then a DLookup in the OnExit or OnChange events should give you the info you need to work with
using your example,
Debug.Print DLookup("ReturnDate","Crew","KitNumber = " & Me.AssignKit)
if KitNumber is stored as a string in the database, then you would need to put quotes around the selection
Debug.Print DLookup("ReturnDate","Crew","KitNumber = '" & Me.AssignKit & "'")
Note that DLookup returns the first one it finds, so if you need multiple values, you will have to look into recordset functions .Find and .FindNext
I have a problem very similar to this one, but I just can't seem to solve it!
In MS Access (2003), I want to search a table based on entries in a number of fields, some of which may be empty.
I have:
text fields
date fields
integer fields, and
a memo field (but we can probably not bother searching this one if it is difficult).
They map onto a table exactly.
I am trying to create a query that will return matching rows when data is entered into one or more of these fields, but some fields can be left blank. How the heck do I do this?
A query like the one on the linked question works for text fields, but what do I do about the number fields, date fields (and possibly even the memo field)?
To give a clear example, the following code block works for TextField1, but not NumberField1:
PARAMETERS [Forms]![SearchForm]![FilterTextField1] Text ( 255 ), [Forms]![SearchForm]![FilterNumberField1] Text ( 255 );
SELECT Table1.[TextField1], Table1.[NumberField1], Table1.[TextField2], Table1.[TextField3], Table1.[DateField1], Table1.[DateField2], Table1.[DateField3]
FROM Table1
WHERE (Len([Forms]![SearchForm]![FilterTextField1] & '')=0 OR Table1.[TextField1] Like '*' & [Forms]![SearchForm]![FilterTextField1] & '*') AND (Len([Forms]![SearchForm]![FilterNumberField1] & '')=0 OR Table1.[NumberField1] Like '*' & [Forms]![SearchForm]![FilterNumberField1] & '*');
I do hope you can help. I'm sure I'm missing something really obvious, but for some reason my brain feels like it is leaking out of my ears at the moment.
Thank you!
If you need it, this is the basic design of the relevant entities:
Table1
SomePrimaryKeyWeDontCareAboutRightNow
TextField1
TextField2
TextField3
NumberField1
DateField1
DateField2
DateField3
MemoField1
SearchForm
FilterTextField1
FilterTextField2
FilterTextField3
FilterNumberField1
FilterDateField1
FilterDateField2
FilterDateField3
FilterMemoField1
You can check fo null values or cast to string
You could certainly spend a great deal of time crafting a huge and very hard to debug SQL query for this, or just jump into VBA and write some code to construct just the SQL you need.
VBA is there just for these kinds of scenario, where something is either impossible or becoming too complex to do otherwise.
With VBA, you can use an initial SELECT query that collect all the data, and then construct a WHERE clause based on the content of your search form to filter it.
For instance, I have a form like this, that allows the user to enter any criteria to filter a list of prices:
Some code to implement this could look like:
' Call this whenever the use click the Apply button '
Private Sub btApply_Click()
' Construct the filter '
Dim filter As String
If Not IsBlank(cbSupplierID) Then
If Not IsBlank(filter) Then filter = filter & " AND "
filter = filter & "(SupplierID=" & cbSupplierID & ")"
End If
If Not IsBlank(txtPartNumber) Then
If Not IsBlank(filter) Then filter = filter & " AND "
filter = filter & "(PartNumber LIKE '*" & txtPartNumber & "*')"
End If
If Not ckShowLocked Then
If Not IsBlank(filter) Then filter = filter & " AND "
filter = filter & "(NOT PriceLocked)"
End If
' ... code snipped, you get the jest ... '
' Now re-construct the SQL query '
Dim sql As String
sql = "SELECT * FROM Price"
If Not IsBlank(filter) Then
sql = sql & " WHERE " & filter
End If
SubForm.Form.RecordSource = sql
End Sub
It may seem like a lot of code, but each block only does one thing, and it's a lot easier to debug and maintain than cramming everything into a query.
I'll try and break down my problem as best I can and explain what I'm trying to achieve. Firstly, I have three tables:
**RFI** (stands for Request For Information)-
Fields: rfi_id, Customer_id .....
**RFI_project** -
Fields: rfipro_id, project_id, rfi_id *"....." represents other unnecessary fields*
**Customer** -
Fields: Customer_id, company .....
I have an access form with two comboboxes. On the first combobox I select the name of a project at which point the second textbox changes to show those *rfi_id*'s where there is a match with the project name selected.
Now what I'm trying to do is this - When I select an *rfi_id* in the second combobox I want it to display in a textbox on my form the company where there the *rfi_id* value matches the value in the combobox. It's a bit tricky due to the way the tables are joined...here is what I'm essentially trying to display in the textbox field in SQL terms:
SELECT Customer.company, RFI.Customer_id
FROM Customer, RFI
WHERE (((Customer.Customer_id)=[RFI].[Customer_id]) AND ((RFI.rfi_id)=[Forms]![Request for Info Form]![Combo90]))
ORDER BY Customer.company;
In order to do this I have tried the following to no avail. In the after update event of my second combobox I have inserted the following:
companyTB = DLookup("company", "Customer", "Customer_id =" & DLookup("Customer_id", "RFI" And "rfi_id =" & [Forms]![Request for Info Form]![cmbRFI]))
When I change the combobox value I get the error Run-time error '13': Type mismatch. I've tried searching for what I've done wrong but this is a very broad error apparently and I can't find anything similar (or that I understand). I also tried this instead -
companyTB = DLookup("company", "Customer", "Customer_id =" & DLookup("Customer_id", "RFI", "rfi_id =" & cmbRFI))
which gives me the following error - Run-time error '3075': Syntax error(missing operator)in query expression. Anyway, would anybody be kind enough to give me a breakdown of what I need to do to achieve this, or what I'm doing wrong (or maybe a better way to do it?). Forgive me for being to seemingly stupid at this, I've only just begun working with access more in depth in the last 3 weeks or so. Thank you.
Your first DLookUp has incorrect syntax:
companyTB = DLookup("company", "Customer", "Customer_id ="
& DLookup("Customer_id", "RFI" And "rfi_id ="
& [Forms]![Request for Info Form]![cmbRFI]))
I have broken it into three lines to make this easier to see. The second line has And between "RFI" and "rfi_id" when it should have a comma.
companyTB = DLookup("company", "Customer", "Customer_id ="
& DLookup("Customer_id", "RFI", "rfi_id =" & cmbRFI))
The error you are getting on your second combo seems likely to be due to the result returned by cmbRFI. You can check this by filling in an actual rfi_id, rather than the reference to the combo and by setting a text box equal to cmbRFI and see what it is returning. Combo can be difficult because the displayed column and the bound column can be different.
It can be convenient to set up your combobox with several columns, as shown in your query, so the rowsource might be:
SELECT rfi.ID, Customer.company, RFI.Customer_id
FROM Customer
INNER JOIN RFI
ON Customer.Customer_id=RFI.Customer_id
ORDER BY Customer.company;
(or the three tables, joined, if necessary)
Then
Column count = 3
Column widths = 2cm;0;0
Bound column = 1
You can now refer to the second column in your textbox:
= cmbRFI.Column(1)
Columns are numbered from zero.
It is always worth reading up on sql before working with Access:
Fundamental Microsoft Jet SQL for Access 2000
Intermediate Microsoft Jet SQL for Access 2000
Advanced Microsoft Jet SQL for Access 2000
Your last Dlookup statement seems absolutely fine so I'm a little confused as to why it isn't working, you may be able to get round the problem like this though:
Combox2_AfterUpdate (Or whatever the event is called)
Dim rs As Recordset
Set rs = Currentdb.OpenRecordset("SELECT C.Company, R.Customer_ID " & _
"FROM Customer As C, RFI As R " & _
"WHERE C.Customer_ID = R.Customer_ID " & _
"AND R.RFI_ID =" & [Forms]![Request for Info Form]![Combo90] & " " & _
"ORDER BY C.Company")
CompanyTB = rs!Company
rs.Close
Set rs = Nothing
End Sub
