IIF Not Returning Data - If "false", Should Return All Results
Dec 29, 2006
Greetings,
I've been banging my head on this for days, and what really makes this difficult is the number of websites which say it should work just fine!
I'm working with Access 2003 and trying to make use of the IIf function. I have given my fields generic names in the examples below.
I have a number of items I want to search upon in my search form. Each item has a check box and a combo box. I want the query to look at the check box. If the box is checked, I want the query to use the value in the combo box. If the check box is UN checked, I want the query to ignore this field and return all values. I thought this was simple, until I tried to do it!
Here is my code, placed in the Field-name criteria box of the query:
This will return all records where Field-name = 2.
So... my original code should work! Because no "false" condition is stated, the query should be blank, and should return all records. But it doesn't! Truly maddening.
Here are some attempts which did not work:
IIf([Forms]![form-name]![checkbox-name]=True,[Forms]![form-name]![combobox-name],>0)
---> The ">0" caused an error. In fact, I can only specify an integer - all else, including things with operators, do not work.
Working with nulls - it does not seem to recognize an unchecked box as a null.
That's the short version of the story - any and all ideas welcome!
IIF function not returning the false value. I have the following results based on the query shown below.
SELECT Trade.Ref_No, Trade.CERS_Price, Market.[USD/EUR_Rate], IIf("CERS_Price_currency = US Dollar.USD",[Trade].[CERS_Price]*[Market].[USD/EUR_Rate] , 0) AS [Price In Euro], Market.[USD/CHF_Rate], Trade.CERS_Price_Currency FROM Status INNER JOIN (Market INNER JOIN Trade ON Market.MarketDate = Trade.Trade_Date) ON Status.StatusID = Trade.StatusID;
Price In Euro USD/CHF_Rate CERS_Price_Currency CERS_Price 35 7 US Dollar. USD 5 91 7 Euro. EUR 13 1,715.00 7 Brazil Reais. BRL 245 759.00 33 Indian Rupees. INR 23.00
As you can see returns all calculations whether is USD or not. Can you help please? Ultimately I want to do this for all other currencies by nesting the IIF function.
I'm really not sure how to go about this. I'm creating a course booking system and when creating a booking I need to check for current bookings with the same employee and course id's (i.e. the employee is already booked on the course). The query takes the employee and course id's from a form, and is initialised when the 'book' button is pressed. It correctly selects if the person is already booked on the course but I want the query to return a value to the form i.e. if it returns null/false then the booking can be created but if it returns a record/true then the booking already exists and a message box can be displayed.
I'm not sure if I'm going about this the right way, can anyone suggest how this can be done as described above or suggest a better way of doing the task?
I have a table that has a list of tasks and checkboxes attached to them to be checked once the task is completed. I need to run a query on the table that will only bring me back the tasks with a completion that is false.
Everything that I read online indicates that this is a difficult task for access. Maybe I can accomplish this in SQL view instead of design? If I put false is all of the yes/no fields, the query brings back nothing.
I am trying to filter a form to show the entire weekend's activity on Monday but only yesterday's activity Tuesday through Friday. Using this code I can return Friday's results on Monday and yesterday's for the rest. How do I get the range Friday to Sunday?
I have a query with two table's in them. One is filled, the other is still empty. Both table's are related to each other with the field "document number".
This was working fine in access 2000, now in 2003 it returns zero results. I am starting to think it is because one table is empty it returns nothing. How can i adapt the query criteria or something else that it shows the results from table one, while table two can still be empty. One table holds the documents and all information about it, the other holds the information wich document is referenced on wich document. Now since i can have documens which don't reference to a document, i still want those in the list.
I have a table listing a number of cell phone products and their carrier along with their status' in the production process. I want the query to return the most recent status for each product for each carrier. However, out of the 20+ products that I'd like the most recent status for for each carrier, it's only returning about 12 products of the most recent status for one carrier.
Any help would be much appreciated! Leave a message if you need more clarification.
Item: Access app front end for an SQL database (production tracking/job logging utility)
Problem: The app has a main search page that allows job entries to be located and opened by varies criteria (job#, job name, etc). I can currently run multiple searches on different criteria successfully but if I open a job window(which has been returned as result of my search) and then close that job window to do a new search my search function will no longer return any results(other then “Calculating….”) unless I close out the access app and reload.
Thanks in advance for any ideas that can point me in the right direction to hunt down my bug.
I'm having an issue with a query I created. When run the query requests an Artist Name. I enter this and it returns one result. However in actual table ther are two results for that artist. The only difference is that for the record that doesnt appear the field labelled "Gallery" has a zero value.
I have checked the table and the gallery field is not set to a required field so I dont understand why it wont show it as a result of the query.
running access 2000. I have a query that I selected to return the Top 1 record sorted descending on the date so it would pick the most recent entry. I did it by selecting Top 5 from the drop down box in query design mode and then changed the 5 to a 1 using SQL View from qry design.
SELECT TOP 1 Class.CourseID, User.UserName, Class.TrainerID, Class.ClassLocationID, Class.ElapsedTime, Class.ClassDate, Class.Comments FROM [User] INNER JOIN Class ON User.UserID = Class.UserID ORDER BY Class.ClassDate DESC;
It still gives me as many records as are entered on the system. How can I get JUST the most recent record entry?
I have built a Project/Resource database for our department, and I am having an issue with 3 computers in the group. First, all of our computers are setup the same (as far as I can tell), however, there are 3 users that have the same issue...when selecting an item from a dropdown, it should populate the dropdown below it with a new list, based on the first dropdown. It is only on certain forms, and only happens on these three computers. If the users log into any other computers, it works fine. I know it's not alot to go on, but does this sound familiar to anyone? I'm at a complete loss!
When I run this query, it shows that 41 records are going to be appended. I click on yes, but when I go into the table to view the appended records they do not show.
Code: Public Sub test() Dim frm As Form Set frm = Forms!StationLevelSummary
[code]...
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 trying to do a string compare between two variables. One string variable is part of an array (which I'm looping through), the other is passed to the function as an argument.the function should return the position of a field in the OrderBy string of a subform.Here's the VBA :
Code:
Private Function SortPosition(strOrderBy As String, strField As String) As StringDim arrSortedFields() As String Dim i As Long If Len(strOrderBy) > 0 And InStr(strOrderBy, strField) > 0 Then arrSortedFields = Split(strOrderBy, ",")
[code]....
The weird thing is, the line in blue returns True when, by watching the variables, it appears that it should not, and returns False when it appears that it should?
I would have thought the expression "[RandomField]" Like "[RandomField]*" should return True?And similarly the expression "[SomeFieldName]" Like "[ADifferentField]*" should return False?Have been using 'Like' for donkey's years and never seen it throw results like this before?
(P.S. The reason I need to use 'Like' rather than a straight = is to account for the possibility that a field may be sorted descending, and therefore to nullify the DESC keyword which may follow any given field...)
I have a db with 2 tables, one containing basic info FirstName, Surname, YearGroup, and another table with other data. I imported a list of names into the first table, firstname and surname only were imported, other field was left empty, other table was also left empty. I made a simple select query to pull all records from both tables and i get no results at all. None of the imported names show on the query results. what I am missing?
I have the following two querydefs. Here is the SQL; qry1 SELECT [dtFind], tblData.dtReading, tblData.dblValue FROM tblData WHERE DateDiff("n",[dtReading],[dtFind]) Between 1 And CInt([intMins]);
qry2 SELECT [dtFind], tblData.dtReading, tblData.dblValue FROM tblData WHERE dtReading Between DateAdd("n",-1*[intMins],[dtFind]) And DateAdd("n",-1,[dtFind]);
[dtFind] and [intMins] are parameters.
I use the querydefs is VBA code as such Dim db As DAO.Database Dim rstDataSQL as DAO.Recordset Dim qdfData As DAO.QueryDef Dim strQdef As String
Set db = CurrentDb() strQdef = "qry1" ‘or qry2 Set qdfData = db.QueryDefs(strQdef)
‘Set values of parameters qdfData![dtFind] = dtDate qdfData![intMins] = intMins
Set rstDataSQL = qdfData.OpenRecordset
qry2 executes significantly faster than qry1, but I am having issues getting the correct results.
If I set [dtFind] = 12/28/2005 10:47:00 AM, both queries work fine. The last returned record has a value for dtReading of 12/28/2005 10:46:00 AM.
However, if I set [dtFind] = 12/28/2005 10:48:00 AM, only qry1 returns the right records. qry2 will not return the record with dtReading = 12/28/2005 10:47:00 AM, but qry1 will. :mad:
I changed the Between statement to “Between DateAdd("n",-1*[intMins],[dtFind]) And DateAdd("n", 0 ,[dtFind])” to see what happens. As I expected, records where dtReading = 12/28/2005 10:47:00 AM and 12/28/2005 10:48:00 AM are returned.
The data should be in increments of 1 minute, although there are periods where data is missing. None of the dates have values like 12/28/2005 10:47:01 AM, i.e. seconds value is always 0.
I’ve tried adding “PARAMETERS [dtFind] DateTime, [intMins] Short;”, and also using CDate(DateAdd()) without any luck.
Whether I am using the queries using VBA/DAO or user input to set the parameter values, the results are the same.
SELECT CPL_CLIENTS.CODE, CPL_CLIENTS.FULLNAME FROM CPL_CLIENTS WHERE (((CPL_CLIENTS.FULLNAME) Like "*" & Forms!frmSafeKeep_AddClient_SearchDesig!txtSearchT ext & "*"));
As the control source of a listbox, so that the user can enter something in "txtSearchText", and the listbox will be narrowed to only those those clients that have a matching part of their name.
The problem is that the user enters, for example, "duncan", and the list returns nothing, when in actual fact there are 5 matching records. If the user enters "Duncan" (note the capital letter), they get all 5 records as they should.
If memory serves, access should only be case sensitive if you tell it to be - and this is working fine on other forms.
The only difference between them is the data source. Other forms are getting data from linked tables in the backend. This form is getting it from a linked Oracle table.
I have a query which pulls up results based on the value of a text box. All works well except one field has a DOB (date) and if I search say for " /1976" I get no results, however search /76 and all the people with that year of birth show then show up. The date is stored in the dd/mm/yyyy format.
I'm using the like [forms]![clients]![searchfield] in the criteria of the query to bring up results.
I have two tables Contacts & Allowance. There is a relationship defined between the two based on Contact ID (primary field/contacts - foreign key/allowance). The Contacts table has Firstname + Surname. I have produced a query based on certain fields in both tables however the result is totally pulling incorrect info.
I'm working on a select query that I have created through the visual query design window in Access 2003, I have multiple criteria but the query is not filtering the results properly.
I'm selecting only records :
where the DeliveryCountry field is within the EU - works where the ProductID does not contain Repair, Upgrade or Rpr - doesn't work where the Demo/Sale ID is 2 - works
I've viewed the code in SQL view but I still can't locate the problem, though I suspect it lies in the treatment of ANDs and ORs.
The SQL is pasted below (I have reformatted with indentations so I hope it is easier to read).
One thing to note: the reason the countries list is split in two is because Access did this automatically when I had one long list. Is there a maximum length for WHERE clauses?
FROM Products RIGHT JOIN (([Demo/Sale] RIGHT JOIN Orders ON [Demo/Sale].[Demo/SaleID] = Orders.[Demo/SaleID]) LEFT JOIN [Order Details] ON Orders.OrderID = [Order Details].OrderID) ON Products.ProductID = [Order Details].ProductID

I have a switchboard which runs a google style search query to find people based on their first name, surname, date of birth or NI number on clicking the search button. It uses the following criteria in the query Like "*" & [Forms]![SearchF]![Firstname] & "*" for each of the above fields.
This works perfectly until someone inputs a record that doesn't have anything in one of the fields. ie, full name and DoB, but no NI number. When a record is entered in this way, the table stores the record but the search query cannot find it.
What is the best approach to returning calculated results in a query. I have been using nested IIf statements that include DateAdd but I think that I am at a point where there must be a better way.
I want my query to calculate a date based on: 1) A Type field from my table 2) A calculated date based on other query fields.
My query has the following fields: [Type] [Action 1] [Projected Action 1] [Projected Action 1 Revised] [Action 2]
I want to create a calculated field for [Projected Action 2] that says:
If [Type] is "A" then if [Action 2] Is NotNull, Null if [Action 1] is NotNull, [Action 1] + 10 workdays if [Projected Action 1 Revised] is NotNull, [Projected Action 1 Revised] + 10 workdays if [Projected Action 1] is NotNull, [Projected Action 1] + 10 workdays
[Code] ....
I would like to keep using nested IIf but I keep running into problems and I thought that there is probably a better way.
Multi search wont return results: Obviously I have my table and search form. But have hit a problem that is probably simple to overcome, but for the life of me I cant see it.
The small peice of code I have used = forms]![searchF]![name1] I have also tried Like"*" & forms]![searchF]![name1] & "*" still not working. The qurey accompanying form (searchF) works to displaying searchF form unpopulated which I believe is correct. I should at this stage be able to fill out the one table heading (name1) where the query should return a result in the (searchf) form but it does not return.
The tables, forms and quries, have all been saved and closed and re opened many times
The form (searchF) propeties have been checked and double checked. I have even built a test table but the same things happen as my main table.
