CASE WHEN Statement Problem
Aug 8, 2007
I am trying to make a field in a query which displays a date based off of the criteria below. I tried nesting IIF statements but I couldn't get it to work so I tried a Case WHEN statement.
CASE
WHEN [Appfrom] Is Null & [Fundfrom] Is Null THEN "7/7/1999"
WHEN [Appfrom] Is Null & [Fundfrom] IS NOT NULL THEN [Fundfrom]
WHEN [Fundfrom] Is Null & [Appfrom] IS NOT NULL THEN [Appfrom]
WHEN [Fundfrom] IS NOT NULL & [Appfrom] IS NOT NULL THEN "7/7/1999"
END
Here is the IIF statement
IIf(IsNull([Appfrom] And [Fundfrom]),"7/7/1999",(IIf(Not IsNull([Appfrom]) And IsNull([Fundfrom]),[Appfrom],(IIf(IsNull([Appfrom]) And Not IsNull([Fundfrom]),[Fundfrom],"7/7/1999"))))))
Neither one works and have no idea how to fix it. Any ideas would be greatly appreciated. Thanks.

Hello, I'm attempting to use a case statement in order to select fields from a column that have names and addresses mixed. I'm wanting to select only the fields that contain names. For example some fields start with an address of "1998 Sky Rd" or PO BOX, or Suite at the beginning of the field. I would like to first select all fields with names in the field and then use an update statement to move/switch fields to another column. The only problem is that I can't seem to get this query to work. Please help!!!
Thank you!!!!!!!!!
SELECT address1, name3=address1 as expr1
Case [address1]
When mid([address1],1,1) Like [A-Z] then [address1]
When [address] is null then ""
When [address] = "" then ""
Else 'Null"
End,
FROM Exercise1;
:confused:

Hi everyone, please help, i am in depserate need here. Am i right in thinking nested IF functions are limited to 7 variables, i need to choose from 12, so i need to use something different
it seems like a CASE function could do what i want it to, but i really have no clue where to start, shall i enter this into a query criteria box, or on the form itself ina new field box...??
Can you give a few hints as to what the code would look like, i have two fields, obviously. One is 'lesson_type' and one is 'cost' i want the cost to change depending on what is selected in the lesson type box.
LESSON TYPE ----------- COST
Beginner 1hour ----------- 15
Beginner 2hour ----------- 29
Beginner 3hour ----------- 42
Test Retake 1hour -------- 13
Test Retake 2hour -------- 25
Test Retake 3hour ---------36
Disqualified Retake 1hour -- 25
Disqualified Retake 2hour -- 49
Disqualified Retake 3hour -- 72
Advanced 1hour ---------- 10
Advanced 2hour ---------- 19
Advanced 3hour ---------- 27
Is it possible to do that, change the cost correpsonding to what one is entered in lesson_type...??? And where do i put it??? What do i do with it??
Thanks, dragon2309

Here is my CASE WHEN statement in SQL. What would the If statement be in MS access?
CASE WHEN LEN(Serial) = 9 THEN Serial
WHEN LEN(CAST(Serial as Varchar(255))) = 8 THEN '0'+Serial
WHEN LEN(CAST(Serial as Varchar(255))) = 7 THEN '00'+Serial
WHEN LEN(CAST(Serial as Varchar(255))) = 6 THEN '000'+Serial
ELSE 'Error'
END
AS NewSerial
Thanks for your help!

hey
Is it possible to use sql case statements in access ?
I have used them in sql server all the time and they are really useful!
I mean statements like this one:
"SELECT iOrderID,dOrderDate,iTotalBeforeVat,iShipTotal,iVa tTotal,iTotal,
CASE sOrderStatus WHEN '9' THEN 'Canceled' END FROM tTmpOrderRpt"
thanks!

Can someone simplify my feeble scratching at a Case Select statement, please?
I have two fields in a table (True/False): IsActive and IsDefault
I would like to convert some If...Else...Then statements to a Case Select statement which details what should be done when any of the possible states of the two fields exist.
Semi-Psuedo example in the (subform) Form_Current Event:
With Me
If !IsActive = True And !IsDefault = False Then
Do Something on the Parent form
ElseIf !IsActive = True And !IsDefault = False Then
Do Something Else on the Parent form
ElseIf !IsActive = True And !IsDefault = True Then
Do Something Else Again on the Parent form
Else
Do Something Entirely Different
End If
End With
What blows my mind is the Select Case Expression bit. I can't figure out how to write this. Any help is greatly appreciated.

If I write a select case statement for a field X i.e. 6 to 7 for example will this:1. Select any fields X where the number is greater than or equal to 6 but less than (and not including) 7B. Select any fields X where the number is greater than or equal to 6 but includes decimels of 7 i.e. 7.5 ORC. Select any fields X where the number is greater than or equal to 6 but includes but literally only includes cases where the the whole number 7 appears>I only ask because in an example in a book I am looking at says:Case 10000 to 20000......Case 20001 to 30000I would have through the word "to" means until but not including but in this case the field that equals 20000 would never be selected?

I have a boolean array, foundState(3), whose 4 elements correspond to 4 variables describing conditions that will dictate what action is taken upon closing a form.
There are only 6 possible outcomes for the array, and they can be divided into just 4 cases:
Case {T,T,T,T}
Case {T,T,T,F} OR {T,T,F,F} OR {T,T,F,T}
Case {T,F,F,F}
Case {F,F,F,F}
What the proper syntax would be for this if I'm trying to create a "Select Case" statement for these 4 cases.

I am trying to get a Case Statement to evaluate multiple conditions. Example: below when I get diagnosis code 20400 and the age_at_diagnosis is 40 the code is basically ignoring the second condition of the Case "And rs![Age_At_Diag] < 18". How do I get the code to recognize both conditions?
Code:
Private Sub cmd_Update_Conditional_Codes_Click()
Dim rs As DAO.Recordset
Dim rs2 As DAO.Recordset
[code]...

I have a lengthy CASE statement in my database that displays specific text in a field based on the value of another. Simple stuff but for some reason it randomly will not work on certain values, and never the same one twice. Is there a commonly known cause for this? I have verified that the spelling and spacing etc. are correct in my code so that shouldn't be causing the problem.

I have a simple SELECT CASE query. I'm not sure how the syntax goes and I want to learn about it.
In the attached file, if you click on "cohort table", you will see the categorization for each unit under "field1".
how will I be able to use a SELECT CASE statement in a query to populate each unit with assigned category?

Details:
I have a Profile form that tracks the expiration date for each client's various certifications. These dates are set up in the Short Date format in the table design of Access.
Problem:
When a user accidentally presses an alphabetic key while updating an expiration date, an Access error message is triggered. This is confusing to my users as these messages are written in Access lingo. I would rather that nothing occurs at all. I wrote a case statement to disable each letter of the alphabet and applied it to the On Key Down Event for each expiration date control on my Profile form to solve this problem, but this must be applied to 28 separate controls. I would rather call a function that disables alphabetic keys for each date control in my form when called.
Questions:
How do I transform my Disable Alphabetic Keys Case Statement into a function that I can call for each expiration date control? I know that when writing a function certain variables have to be declared and/or initialized.
Also, will I need to create a function to re-enable alphabetic keys or is this unnecessary because the disable alpha keys function will only be called for specific controls, not the entire form?
What I Have Tried:
I have tried copying and pasting my Disable Alphabetic Keys Case Statement into a module to attempt to create a function, but it needs work.
Below I have included 2 types of code:
(1) The original On Key Down code applied to each date control on my form
(2) The same code written as an attempt at a function
Original Profile Form Code to Disable Alphabetic Keys in the On Key Down event for each date control
Private Sub txtCert1ExpDate_KeyDown(KeyCode As Integer, Shift As Integer)
Select Case KeyCode
'All message box text is for me to test the code, not for the user to see
Case vbKeyA
MsgBox ("you pressed the A key")
[Code] .....

I have a query with the following criteria in one of the fields:
>=DateAdd("m",-12,fom()) And <=DateAdd("m",1,fom())
fom is a function for first of the current month. I need this query to be specific to what month it is when its ran so i want to only have this criteria if the month is > = october. If it isnt October or greater, i want the criteria to reflect this.
>=DateAdd("m",-12,fom()) And <=fom()
Which also works by itself. But when i add it to an iif statement it always produces no results. Below is the iif statement.
Iif(month(date())>=10, >=DateAdd("m",-12,fom()) And <=DateAdd("m",1,fom()),>=DateAdd("m",-12,fom()) And <=fom())
I have also added the column name to each expression and it still doesnt produce any results.

I am creating a multi-search form for a student database, where after I enter my search criteria I hit a "Run Query" command button and then it opens a query form with all of my criteria.So far I can search using last name, first name, and middle name. When I try to search with a start date and end date I am have issues.The start date and end date is for the class date. In the query form under the field, class date, for criteria I wrote:
Between IIf([Forms]![Search Form]![Start Date]="",1/1/10,[Forms]![Search Form]![Start Date]) And IIf([Forms]![Search Form]![End Date]="",4/25/15,[Forms]![Search Form]![End Date])
I want it when I write a date in the start date and end date I want it to give me a list of all the students who took the course between those dates. Also, if I leave the dates blank I want it to search all dates. The dates 1/1/10 and 4/25/15 are just the dates I gave because that is far back as my database goes.

I have an Option Box that contains three Report Choices, Report1, Report2 and Report3. I want to run the Reports. I coded using If-Then and it worked out fine. See code below:
Private Sub Frame0_Click()
If Me.Frame0 = 1 Then
DoCmd.OpenReport "Report1", acViewPreview
ElseIf Me.Frame0 = 2 Then
DoCmd.OpenReport "Report2", acViewPreview
Else
Me.Frame0 = 3
DoCmd.OpenReport "Report3", acViewPreview
End If
End Sub
I would like to get the same result using "Case." However, when I use the Case format, it does not show all the reports as it does in the IF -Then format. See Case format below:
Private Sub Frame1_Click()
Dim Test As Integer
Select Case Test
Case Me.Frame1 = 1
DoCmd.OpenReport "Report1", acViewPreview
Case Me.Frame1 = 2
DoCmd.OpenReport "Report2", acViewPreview
Case Me.Frame1 = 3
DoCmd.OpenReport "Report3", acViewPreview
End Select
End Sub
Something simple is missing at the top. Please advise as to how to correct this?

Someone was helping me out and sent me the attached code to connect to a SQL server from Access2000 in a query. Access doesn't use the CASE statement, but the IIF statement instead. Can any of you help in deciphering the below CASE statement into an IIF statement?....

I have this code in an event property on a report and it is working great. However, I now need to do a second case based on which modules are down. Is it possible to have a select case within a select case? I have the select case for the systems now with in each system I need a select case based on modules?
Dim dbs As DAO.Database
Dim rst AS DAO.Recordset
Set dbs = CurrentDb
Set rst = dbs.OpenRecordset("Select * From YourTable")
While Not rst.EOF And Not rst.BOF
Select Case rst![System Number]
Case 42144
' do this
Case 88754
' do this
Case Else
' do this
End Select
rst.MoveNext
Wend
rst.Close
Set rst = Nothing
Set dbs = Nothing

How can I set up a table so that as we assign a case it generates a new number with the year in front of it. I would like for the case number to be generated by the program and when someone enter a new case the program generates the next case number and assignes it to that case. The format we use for our file numbers are year-XXXX (ex: 07-0001). With the new year I'm trying to set this up so that as we start the year the computer will generate the new number.
