Making Criteria Optional
May 7, 2007
I have a form with an option group that depending on which one is selected, opens a report with a specific query as it's source. Part of the query looks at a listbox on the form. Here is the criteria for a field: [Forms]![frmOnSearch]![tboCollDev]
I want to make this criteria OPTIONAL. So if there is nothing selected in the listbox, the query should not look at that criteria. FYI, the value that is returned from the listbox is numeric.
Thanks

I've had a look around this forum and haven't seen anything really matching my needs, but please feel free to point me in the right direction.
What I am trying to do (using macros & queries - very new to SQL / VBA) is filter by multiple fields, but also allow the user to choose to filter by different combinations of fields - such as searching for first name and suburb, or salesperson and customer source, or first name and salesperson, or suburb and customer source, or three options or one, etc etc.
There will only be a certain number of search fields, probably five or six, but how do I get the query to recognise that if one of the search boxes is blank, it should allow all records in that field and only search by the other criteria, but if all the search boxes are filled in, the results must match all the criteria?
Does this make any sense?
PS - I am planning to use a command button as an "Apply Filter" so that the filter only updates after the user has specified all the options they want.

Hi,
Is there a simple way to add optional criteria in a query for a subform? Basically, what I'm trying to do is have a number of comboboxes in the parent form that indicate what records are shown in the subform (these records could then be added and/or deleted). I would like to be able to have a combobox such as "Month" that would filter the data shown in the subform to that month. If no month is selected, then the subform would show all months.
Any help would be much appreciated.

I am using this criteria with my calender on my form...
>=([Forms]![frmReport]![txtFrom]) And <=([Forms]![frmReport]![txtTo])
but I have 2 other date fields that I would like to query, so how do I go about making this optional?
Normally with a simple reference like:
Like([Forms]![frmReport]![txtFrom]) & "*"
with the form control's default value as * I tried working with that configuration but either it is not possible or I have the wrong syntax.
I'm open to a VB solution if anyone has one?
Note: I would only be using one of the date fields at any given time
thanks

On the access form I have designed , I need to give optional search option to the users. I have the following search options on the form (screenshot attached):
From Date
To Date
Port
Vessel
Voyage
---------------------
The query is as follows:
SELECT dbo_VESSEL.VESSEL_NAME, dbo_VESSEL.VESSEL_CD, dbo_VESSEL.VOYAGE_NUM, dbo_VESSEL.PORT_CD, dbo_VESSEL.DEPART_ACTUAL_DT, dbo_VESSEL.DIVISION_CD
FROM dbo_VESSEL
WHERE (
(dbo_VESSEL.VESSEL_CD Like [Forms]![VESSDAT].[Form]![txtvessel]) OR
(dbo_VESSEL.VOYAGE_NUM Like [Forms]![VESSDAT].[Form]![txtvoyage]) OR
(dbo_VESSEL.PORT_CD Like [Forms]![VESSDAT].[Form]![txtport]) OR
(dbo_VESSEL.DEPART_ACTUAL_DT BETWEEN [Forms]![VESSDAT].[Form]![txtfromdept] And [Forms]![VESSDAT].[Form]![txttodept]));
----------------------
However, the form still prompts me to enter values for all the boxes and still doesnt show the correct data.

I have two drop-downs on a form along with a child form that shows data based on a query. If both drop downs have selections, say date and dept. then the query would change and the child would show the data - that works fine, but what if one of the drop downs didn't have a value selected, as in i select a date but just want all departments so select noting from the second dd - how would i write the query to reflect this optional selection?

Is it possible to have three different report footers on the same report? I want to show one footer at a time depending on a condition met in the detail section. I already know how to check the condition but I need to know how to do the rest.
Ex:
if condition1 = A then
me!reportfooter_1.visible = true
me!reportfooter_2.visible = false
me!reportfooter_3.visible = false
end if

I currently have a bound form that adds a new student, however, I've decided I don't like bound forms as weird stuff can happen (like when the user exits in another way than I anticipated) so I'm making an unbound form which will add the student when a button is clicked. I already have this working on some other places so this should be no problem anymore.
However in my database a lot of student information is optional and only a first and last name are required (and ofcourse an autogenerated PK). So my question is how do I deal with these fields that might or might not be empty?
I could make a fairly big If ... ElseIf... construction where I slowly fill a String with all the optional fields but I was wondering if maybe there are some better ways to approach this?

How to get a third combo box on a form to be optional.
I have a form with two combo boxes which filter out the results on a query.
However I want the third combo box to be optional i.e. if it is blank then just the results of the first two combo boxes are shown. If the user selects all combo boxes then obviously the results are based on all combo box selections.

I have a subform and when you double click on any field it remembers 3 fields from the record you are in and stores them. I have 3 fields called [section], [losthrs], [stdhrs]. It works perfectly and stores the data from [losthrs] and [stdhrs] fields, but throws up "Argument not optional" for the [section] field.... Can not see a reason why, it is just a simple text field...
I have even tried 'pausing the code' and using the immediate window to show the field values, again losthrs and stdhrs are fine, section gives "Argument not optional".

I am amending some Code I found online for an audit table, I need to store additional information in the table that is associated with some forms but not others.
I have researched about putting optional variables in, but I read this only works with the type VARIANT.
Is there a way to make a string optional as my fields contain text?
here is my code so far:
Sub AuditChanges(IDField As String, UserAction As String, Optional UserID As String, Optional DeviceID As String, Optional SimID As String)
On Error GoTo AuditChanges_Err
Dim cnn As ADODB.Connection
Dim rst As ADODB.Recordset
Dim ctl As Control
Dim datTimeCheck As Date
[Code]...

I'm relatively new to MS Access (using MS Access 2013 but the db should work on 2010, too) and try to develop a database for an NGO I'm working in. I created almost all the tables (all that I need for now) and made the relationships.
However now I start to create forms and later reports for the actual user. The database will store information about clients and track consultations and assistance the NGO gives to them. There will be around 50.000 to 70.000 clients in the main table. Every client has a specific Individual ID and is member of a family which itself has another specific Group ID.
Now here is my problem: The User usually searches for the respective family by the Group ID. I implemented this with a search query using the ID number of a search text box. All done and no big problem.
But sometimes the ID number is not known so the user needs to search by name (First and Last Name). I use to different textboxes for this and it works in a similar way like the number search by query (Like "*" & [Forms]![frm_SearchIC]![txt_LName] & "*"). All still good However since most of the clients are actually from arabic speaking countries, converting the names into the Latin alphabet is bound to fail and produce a lot of misspellings. Therefore I added 2 more textboxes and 3 comboboxes for the user to give more information about the client and therefore make it easier to search for the person. I was able to produce a query which gives you the right result if you have ALL information at hand. However, this is not always the case.
1) But I cannot find a way to tell the query that if the a certain textbox or combobox is empty, it shall just "ignore" it and use the information at hand. I tried this in the query by adding in the criteria OR .... Is Null. This is alright for one or two textboxes but for the many I have, it seems to be too many different combinations for the criteria. It just worked with some fields but others always had to be filled in...
2) If no information is given at all, the database should inform the user that he needs to enter at least on field. If nothing is found the user should get a msgBox saying "No IC matches your criteria".
3) The results of the searches should be given out in another form where the user can pick the person from 1-to-many results.
I attached a sample database with sample data and reduced tables, fields, and entries ...

;) Hey everybody,
I am working on a database used in recording device characteristics/test information. The main table of information has dozens of columns for test/part detailed information. When inputing the data for each specific test, many of the info. details are repeated when testing say 20 devices of the same part all at once. Rather than retype every piece of detailed information in every field, everytime, is there an easier way? Does anyone know of a way to make specific fields copy/paste the previous record's information in the fields automatically when a new record is created? Please, if anyone could help or has ANY ideas, let me know...
Thanks

I want to be able to set text boxes so that if one enters a date and a time it displays in the format "dd/mm/yyyy hh:mm", but if one just enters a date is displays in the format "dd/mm/yyyy". Is this possible?
Stipulating "dd/mm/yyyy hh:mm" means that when you just enter a date it adds "0" values for the time e.g. entering "21/6/13" gives "21/06/2013 00:00".
General Date allows for an optional time, but it means that when you do enter a time it gives you seconds as well "dd/mm/yyyy hh:mm:ss" - and I don't want that.

I have set up a database that stores actions (i.e jobs). In the table; two of the fields are...'required completion date' and 'actual completion date'. I wish to lookup, by using a query, all of the open actions (those which havent yet been complete (i.e the 'actual completion date' is null)) and then later on all those which are overdue (i.e the 'actual completion date' is null And the 'required completion date' <today....this being the criteria for an overdue action).
However, I have used a form which has a combo box which contains the values open and overdue. When a selection has been made I want a form to display with the results depending on the selection that has been made. I am capable of creating a form based on a query, but am unsure of how to construct the query with the correct criteria based on the option that is selected from the form.
Any help would gratefully be appreciated. Thanks

I created a form that allows the user to choose the criteria that they want to see on a report using =Forms!formname!controlname in my query. It works great but I want to also allow the user to choose nothing and return all records instead of limiting them to choose just one type of record. Is this possible? Before I created the form my query had the [Enter parameter] on one criteria line and [Enter parameter] Is Null on the next criteria line and that was working great for my use but I need to create a simple form for other users.

I am not sure where to post this so could someone please move it to the appropriate area thanks.
I want to make a graph that will show how many employees are in the company for each year (Going back 10 years and keeping up to date) I have never done this before and our teacher feels that its best if we learn on our own (basicaly he's an idiot).
How do I go about using the pivot chart?
I have made a query which adds up the total number of employees at the current time.. but apart from that I havent a clue. I want the graph to have the years on the bottom and numbers up the side (1,2,3,4,5 etc) and then the number of employees that were in the company during that year will be plotted.
I will use a table that is to be used for archiving to mke the query as it will have all the employees who were ever in the system record.
The table is thus:
Employee_ID
Emp_First_Name
Emp_Surname
Age
Emp_Home_Number
Emp_Mobile_Number
Emp_Address_1
(so on and including postcode)
Date_Started
Position_ID
I have no idea what to do other than to rename the axes and change the increments, but they are jsut numbers, no dates or anything.
Any help apreciated.
