Setting Field To Null
Jan 28, 2013I have a form to enter attendance in that pulls students from a StudentEnrollmentTable based on FacultyName which is selected from a combobox that runs the following code:
Private Sub cboInstructorName_Click()
Me.Requery
End Sub
A query (StudentAttendanceBYFaculty) is run each time a faculty name is selected. On the form their is a field name TempClassesAttended which is bound to a field of the same name in the StudentEnrollmentTable. Teachers will enter attendance data and run an append query to append the current form records to the StudentAttendanceTable. Each time the form is repopulated the most recent TempClassesAttended values are pulled into the form. This is what is expected.
Now I want to load Null values into the TempAttendance field on the form each time the Faculty selects their name and runs the event. I looked at code online and it seems easy enough, but I don't know enough to make it work. This is the code suggested:
UPDATE TableName SET FieldName = Null
OR
UPDATE MyTable
SET MyField = Null
how to include this into the current event so that the event will return the faculty records with Null values in the TempAttendence field.
Modules & VBA :: Setting Variable To Null When It Has A Value?
Jan 21, 2015 I have the following simple variable assignment...
Dim PolRef As String
Let PolRef = Me.Policy_Ref_Num
But when I run my code I get "Invalid Use of Null" and PolRef is set to ""
This field is populated however, so I'm confused to why I cant set my variable to it.
If I don't use a variable and simply have let XXX = me.Me.Policy_Ref_Num then it still wont return the value from the field.

Queries :: Checking Query For Null And Setting Operations
May 30, 2014I have been working on an application where I am collecting survey data in a database. There are multiple survey tools available to the user, and it's possible to complete multiple survey tools in the survey.My problem is, it's possible for the surveyor to complete some tools on one day and other tools on another day. I am having problems with trying to figure out how to add a tool that has not been previously added and keep in the same survey which is all held under a single Survey Number.
The first step in the function is to set a Record Number temporary variable based on whether or not the tool has been used (it's possible to use multiple instances of a survey tool, so need to know if the Record Number is '1', or the next number in the sequence.I've been trying to do this by checking a query for a Null and setting the temporary variable using something like:
IF ISNull("RecordNumber","qryRecordHeader") Then '1'
Else
DLast("RecordNumber","qryRecordHeader") +1
End IF
The second half works just fine, so if there is a previous record, it will add. But if it's Null, it doesn't work.I'm trying to avoid opening a temporary form to run the query and checking a field. Is there a way around that?
Tables :: Setting Primary Keys To More Than One Field In Table / But They Cannot Have Null Values
Nov 30, 2012Access 2010..One organization that we work with provides us with a block of numbers for each of the two types of contract products we order from them; we do order non-contract stuff from them also.The block of numbers are the same (i.e. 20000 to 30000 this year) for each of the two products. This means that each product can have the number 20000, for example. We call this the Tracking Number. If it is one of these products, we need to select the Contract Number.
For all other one off orders we have with them, we assign our own Tracking Number starting with 00001. This Tracking Number cannot duplicate unless it is one of the aforementioned two products.Both the Tracking Number and Contract Number are in the same table. The user selects the Contract Number from a form (connected to the Contract Number table that has all the details on the contract) and the Contract Number is populated in the same table that has the Tracking Number.Each order must have a Tracking Number (no null)..Not all orders need a Contract Number (null okay).The Tracking Number and Contract Number combination cannot duplicate.I tried setting the primary keys to more than one field in the table, but they cannot have null values.
If not... I have been working on Plan B.... an AfterUpdate on the form (either the form or a field... don't know yet) that looks at a query that only has results if there are duplicate values.
Modules & VBA :: Switch Function - A Null Makes Whole Column Null
Nov 16, 2014I do not understand what is happening here. I have foll0wing line in a calculated query field:
m: Switch([EmpID]<5,1) ' run Query 18 in attached example, A2007/2010
this produces 1 for all EmpID<5 and Null for all other EmpID's. All as expected.
But if I do this:
m: Switch([EmpID]<5,1,[EmpID]>=5,Null) ' run Query 19 in attached example
then the entire column is set to Null

Query With Is Null Returning Not Null Records
Apr 18, 2006Hello all,
A bit of a weird one, I've got a query and the criteria for showing records is that one particular field is null. However the query is showing records with the values in the field chosen for the Is Null.
Not sure why this is happening, has anyone come across this problem before?
Thanks.

Field Criteria: Is Null; There Are Null Values In That Field; No Records Are Returned
Nov 16, 2007I think the title pretty much sums it up....
I have a query where data is first sorted by user input; first field's criteria: [fieldname], then by another field's criteria: Is Null.
I know there are records containing null values in the second field, as I have run a select query with the criteria: Like "*", to make sure they are null, and not zero-length-strings.
The query is refusing to return any results...
Any ideas?
Setting Up A New Db
Feb 15, 2007Hi Guys,
ok I work a lot on databases but have recently been asked to set up an access database for my team. We are a marketing team within a large insurance company and need a small access database for MI and project management.
I have made a start on this and going well so far but there are some things I need it to do that I dont know how :P
Ive never messed about with Acess before so bare with me :P ok so this is what im looking for, any help would be greatly appreciated.
I have set up various tables for look up wizards for some of the menus on another table I designed for the raw data entry.
I need two tables, two forms - one table for very basic generic data such as
- Job Number
- Description
- Business Unit
- Owner
- Due Date
- Completion date
I then need to drill down into this to add more information, so its basically two tables on top of each other with co-dependencies.
So for example one of my team enter a new project at the very basic lvl, they have a job number, they know what business unit it is for and they know the date its due, as time goes by and work is done on the project I want them to be able to click on a button that takes them to another form where they can enter information that is linked to the original information.
So they search for job number 00000 and come up with the above data on the first form, I want them to then click on 'Project Information' button and be taken to another form that has a lot more stuff on there, like a description, complications, notes, links to documents etc etc. I tried to do this linking two tables together but it doesnt work as the two forms/tables are not co dependend and are irrespective of each other.
Does this make any sense ? and does anyone know how I might make this work ? Please let me know if I am not clear and I will try to explain as best I can
I would also like to change the form 'theme' aswell and have my companies logo transparent behind the data fields etc, anyone know how to do that as I only have the option to use the standard themes.
Any help would be greatly appreciated

Setting References
Jun 22, 2005Is it possible to set which VBA reference boxes are ticked each time a database is loaded?
A problem is created when a person amending the database to the person using it has different setups and so some of the references show as "missing" and so compile errors show on loading.
We are using Microsoft Access 97.
Any help most appreciated.

Setting A Value To An Option Box

Odd Problem...is It A Setting?
Feb 14, 2007I tried various searched and came up empty handed.
I have a user that is using a database that is on a network. When she enters records using her computer and exists the database, they don't save. If she goes back in, they aren't there. However, if she uses another computer, they save.
I can assume that it's not user error because it's the same user on two different computers.
Any ideas?
Setting Up Tables
Mar 4, 2007I am confusing myself more and more as i read on normalization and queries and everything else. I am trying to create a database for parts that our company sells and am having trouble deciding how to lay out the tables. I figure I should use the part number for the primary key as it will not repeat. from there though, i have a problem, each type of part has different fields nessesscary to decribe its attributes. for example, one part number may be for a box and its describing fields might be brand, width, length,load rating, and height. but another part number might be for a circuit breaker which would have completley different describing fields like brand, amperage rating, voltage rating, connection type, and trip type. Should i create 1 table for everything even though many fields would be blank depending on which type of item it was or should i create seperate table for each type of item with only the required fields to decribe that item?

Jan 17, 2008Hi,
i have a subform within a form. when the form is loaded, i would like the subform to automatically be ready for a new record instead of shown the last record entered. i have tried various macros ( not VB ) but to no avail. the form shows the persons info and needs you to add a certain piece of info. this would be the only reason for the form.
can it be done?

Help With Setting Up Tables
Apr 18, 2006Dear all,
i have having such trouble setting up some tables in a new db, and am wondering if someone could give me some tips as I really don't know what I'm doing (I am new to this).
I have one main table, called Client Information. The PK is CaseNumber. I also have 11 other tables. The PK in each of these is called things like CasedetailsID, witnessinfoID, etc. Each of these tables contains the CaseNumber field (supposed to be from the Client Information table). The Client Information table contains the PK from each of the other tables.
The way I have the relationships set up at the moment is that the Client Information Table is linked to each of the other tables via the fields called casedetailsID, witnessinfoID, casetypeID, etc. The relationships are all one to many (the 'many' side being on the Client Info table, the 'one' side being on the related tables). There is obviously something incorrect about the way I have the tables set up, however, as when I try to enter data into the form, although the data gets stored in the individual tables, none of my queries or reports seem to be working (ie, I try to run a report, but it doesn't show any data).
any tips or advice regarding a good way to go about setting up tables and relationships would be very much appreciated.
Help Setting Up A Database
May 11, 200717412 Hi, I am trying to set up a database for organizing Track and Field meets. I'm a newbie to a lot of the Access capabilities. I've attached a PDF of what I'm looking at doing for my Access tables. Some of the tables I think I have right. I don't know how to organize the meets, events, days. Should I have a table for each event? Can you look at my tables and give me advice on problems you can see? In the end I would like to enter the event results by race. Some races could have 10 or more heats. There are also field events that have different number of attempts depending on the meet. There are different track meets with different events each time and the order in which the events occur changes from meet to meet. Any help or advice you can give me would be great. Thanks!

Setting Up A Table
Nov 9, 2007Hi
I feel really stupid for asking this, but I am so stressed at the moment, I can't concentrate!
I have a database that stores land locations and information relating to it. In the database, I need a form that asks 13 questions and answers are given in drop down boxes (about 3 answers to each question). Each of these answers relate to a score, which I want to be able to show automatically.
What I would like to know is how to set the table for it. This table has to use the ID from the land locations table (which is sorted by the way).
Please see the attachment for a simple design of what my 'boss' wants it to look like. The form for this table will be a subform on the main form for land locations.
Please can someone help me? I would really apreciate it :)
