Is Null Not Working, But Does Work If Change To <1?
Oct 5, 2007
I have a query, and it has been working just fine, till today. I have it based on a field being null. This field shows null in the table, it is a text field but it is a 19 digit number if there is anything in there. The fields didnt come up in the query when it was based on Is Null. But if I changed it to a <1 they came up just fine. and After further testing, the change works just how I had it working with the Is Null or so I thought. Any ideas on the WHY behind this, I am really curious about it, thought I would get some opinions on why this happened.
if a field contains some null values, then how to replace each of these null with its previous value ? eg: Phone No Bill date Amt Pending 222000 2-2-07 3456/- null 17-2-07 2356/- 224000 12-2-07 1235/- null 08-2-07 456/
now i want to fill the blank below 222000 with 222000 and 224000 under 224000. how to do it? plz guide me for office 2003.
Hello, I am putting a check whether the inputted value in a text box(txt_id) is filled or not. If it is 'null' then it should not execute the insert statement but somehow the check for the null value is not working. Can someone tell me why??
Private Sub cmd_inserer_Click()
If txt_id.Value = Null Or txt_id.Value = "" Or txt_id.Enabled = False Then info = MsgBox("Veuillez remplir champ « Id »", vbInformation)
ElseIf txt_id.BackColor = &HFF& Or txt_libelle.BackColor = &HFF& Or txt_description.BackColor = &HFF& Then
info = MsgBox("Veuillez remplir tous les champs fausses!", vbInformation)
Else MsgBox txt_id.Value Set db = CurrentDb strSQL = "INSERT INTO objectif ( id , libelle,description) values ('" & txt_id.Value & "' , '" & txt_libelle.Value & "','" & txt_description.Value & "') ;" db.Execute strSQL db.Close
I have a database that I maintain the history of our football league in. What I am trying to do is count each team and the number of wins in each year
The query works fine except in the cases where the team had ZERO wins. Then of course it returns nothing and screws up the other queries when there is a hole for a year.
2 Tables in the database
INFORMATION TEAM YEAR (other fields not relevant)
SCORES TEAM YEAR RESULT (either WIN, LOSS or TIE) (other fields not relevant)
I want to count the number of wins and return it to this query EVEN IF THE NUMBER OF WINS IS ZERO (0).
In 2002 Westside was 0 wins -11 losses and the query not finding any WINS in 2002 did not return a record.
How do you get the query to show 2002 Westside 0
========================== Current SQL Query SELECT Information.Year, Information.Team, Count(Scores.Result) AS CountOfResult, Scores.Result FROM Scores INNER JOIN Information ON (Scores.Year = Information.Year) AND (Scores.Team = Information.Team) GROUP BY Information.Year, Information.Team, Scores.Result HAVING (((Information.Year)>2000));
basically am creating a booking system, i have a add a room form. my form should check whether i already have a room number in my table, which works when the form is filled in. however when my form is null, then i press add new room button, i get this error rather than " please fill your form in"
Error: runtime error '3075' syntax error (missing operator) in query expression 'Room Number ='.
room number is a number field, integer but has primary key. i cant keep autonumber, as my requirement is to add new room number, but the roomnumber has to be unique.
here is the dlookup;
If DLookup("RoomNumber", "tblRooms", "RoomNumber = " & Forms!RoomPackages!txtRoomNumber) > 0 Then MsgBox "This number already exists." Else
Hello. I've searched and read a few threads concerning image controls on forms and haven't been able to find a solution to my problem (yet). Anyway, I have a form with two image controls (imgOK1 & imgOK2). The previous and current setting of the "Picture" property for both images is set to "C:MOMGraphicsfilename.bmp". The location of my images has changed and will change for each user which is "C:Documents and Settingsuser.nameMOMGraphicsfilename.bmp". I'm using the following code to set the .Picture property on form load:
Dim ImgPath ImgPath = "C:Documents and Settings" & Environ("username") & "My DocumentsMOMGraphics" Me.imgOK1.Picture = ImgPath & "imgButton-OK1_25%.bmp" Me.imgOK2.Picture = ImgPath & "imgButton-OK2_25%.bmp"
When the form is opened, an error stating that the image located at "C:MOMGraphicsfilename.bmp" cannot be found; once for each image control. Then the form loads and .Picture properties appear to be set correctly as they are displayed fine. I've tried to clear the .Picture properties for both image controls using the properties editor but the original path returns as soon as the property loses focus. Is there a way to programatically set this property and make it stick so the errors are not displayed?
I have an append query created to add files to a table from an imported excel file. The table to which I am appending (SubTBL) has a field names Observation. This field is not required. There is a relationship to another table (ObservationTBL) which has 3 records. The information I am trying to append includes 7000 records, about 4000 have observations assigned and they match the information in the ObservationTBL. The remaining 3000 have blank records for observation. When I run the append query, only those with observations are appended. The rest are not added because of "key violations". I removed the relationship between the ObservationTBL and the SubTBL and the append query runs. Then when I try to re-do the relationship it fails "Violates referential integrity rules".To be clear:
1. The records without an observation are blank. (There are other fields in this append that have blank fields also and they are not causing any problems) 2. The field observation is NOT set to required.
I have create a table clients that contains multiple column i.e. Id, First Name, Last Name, Starting Date, Company , while defining the table I did not mark REQUIRED property of any column
I have created a form based on this table "CLIENTS",
I create the company as combo box and taking the list from COMPANIES.ID
I put the validation rule as IS NOT NULL and put validating text Select Company from list.
If I marked REQUIRED property of this column in table definition as YES then it displays system generated message with tablename.controlname, while i want to display my own message.
But when i input the data and leave the Company column blank the validation is not executed.
There are three columns in the form on which I want to apply the same validation.
I have a question about errors on null value.I have made a small database for tryout, it has to be implemented in another one.And the small database is working.I have one table where there is one field called BatchInput.I scan a barcode into it and let two query's breaking it apart. I scan this batch into the table field
BatchInput: 20 MAY 2004H149-082-79 A4147011A05
Then I have my first query (Qrybreak1) extracting the date and deleting H14
And query (QryResult) even wont start, giving a popup with Invalid procedure call..How could I handle Null on the part where there is no space after the partnumber (missing Certnumber)?
Access 2010. I've had to learn it at work because our DBA was let go and I was the only one willing to give it a go. Read a book or two and picked up some stuff on the internet.
Here's my problem: I have a simple table -Employee with 4 fields. FirstName, LastName, Office and JobTitle. I have form called Form1 that has 3 control fields cboJobTitle (a combo box that is populated by a query that finds all the unique values of that field in the Employee table), cboOffice (same as above) and txtName (a text box to allow user input) that are used as the criteria for a multi-field query triggered by a button at the bottom of the form. The idea being that you could do a search using this form to find all the employees in one office or all the accountants in one office, or any other combination.
The main search query has the following criteria for each field - Like [forms]![Form1]![cboOffice] & "*" Like [forms]![Form1]![cboJobTitle] & "*" Like [forms]![Form1]![txtName] & "*"
It works great...until I enter a record where one of those fields may be null, such as if I leave the JobTitle blank. If I have two employees in an office in one city and then do a search for all the employees in that office, it only returns one record and ignores the one that has the null value in the JobTitle field.
Im trying to change the background colour of some fields if the value is null or missing, but I'm not quite sure how to handle the coding. The fields in question are title, given name and surname, and if they are empty I want to change the background colour to highlight to users that they need to collect this information. Any help that you can provide would be great!
Can you please help me with an “IF” statement. Here are the two formulas I want to use: #1. ToDate Billing: DateDiff("d",[Start Date],Date())/30*20 #2. ToDate Billing: DateDiff("d",[Start Date],[End Date]/30*20 I want to use formula #1 (w/current date) if an end date is not entered. If an end date is entered, then #2 needs to be used.
I would appreciate any assistance anyone can offer.
I am trying to update values in an unbound text box based on a selection in the combo box on the same form; however whilst I am easily able to display the information for the first selection the values do not update when I change the value in the drop down.
We are creating a simple database to maintain driver license information for faculty, staff, and students who use cars from the university’s motor pool.
To do this, I have created two tables: tblDRIVER and tblLICENSE.
The fields in tblDRIVER are: pkfDriverIndex strLastName strFirstName strInitial strAddress1 strAddress2 strCity strState strZIP datBirthDate
The fields in tblLICENSE are: pkfUpdateIndex fkfDriverIndex datDateUpdated strState strLicNumber datExpirationDate ynViolations ynActive
Information about the driver is stored in tblDRIVER and the driver’s license information is stored in tblLICENSE. Periodically, we run a report that identifies drivers whose licenses are due to expire within a certain number of days. All this works fine.
My problem is that I am trying to create a lookup form that will load from a data entry form that will permit the Motor Pool Clerk to look up a driver by name and review the licensing information (which appears as a subform).
All this sort of works- I am using a combo box (based on a query) to look up a driver’s last name (which it does) and to populate all the driver’s information on the look-up form (including license information in a subform). Currently, the combo box locates the driver (including the unique index, last, and first names), and populates the form with first and last name but the rest of the information is not displayed on the look up form. Worse still, sometimes one driver’s last name matches up with the first name of the next driver listed in the table! This seems to happen only if a look up is attempted more than once. What gives.
It might be an easy one but I just wasted the past hour deciphering through my code in order to solve the run-time error '94' that I'm getting when trying to execute the following code:
Code: Private Sub cmdUpdateDates_Click() '################################### 'This sub aims at combining the timesheet date and the start and end time into the fields [Start Time] and [End Time]. '################################### Dim intCounter As Integer intCounter = 0 Dim rs As ADODB.Recordset
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?
I have an expression in one column of my query and It keeps returning a negative result and there are no negative numbers in the source data. Can anyone help. I just want to sum the sums the two IIf expressions, but its not working. Thanks
Other Qty: Sum(IIf([QSum]![ACCOUNT]=2 And [QSum]![ICUNIT]=95 And [QSum]![UNITS]="ITEM(S)",[QSum]![QUANT],Null)) Or Sum(IIf([QSum]![ACCOUNT]=2 And [QSum]![ICUNIT]=100 And [QSum]![UNITS]="ITEM(S)",[QSum]![QUANT],Null))
I am having problems with setting up a set of combo boxes.
What I am trying to do is if combo Productline is empty then in combo PartNumber would show all products but if combo Productline has a value selected then in the combo partnumber would only be able to select the partnumbers in that productline.

I have a program that runs under access 2007 that I use at my work. We will soon be updating to MS office 2010 and the program will not work now because a calender file .ocx was removed from access 2010. Is there a way to get the 2007 .ocx file to work in access 2010?The program I am using is a relatively simple stand-alone and unsupported app that we use to request patient arrival and departure from various radiology tests inside a hospital. No reports are made from the app other than the number of patient transports for the day.
The app is placed on a common drive accessed from any pc in the hospital. No special permissions are required. But our app does use the calendar, time and date functions in access 2007. When I tried the app on a pc with access 2010, it basically says it (access) cannot open the app because a .ocx file is not present.Is there a way to make the access 2010 calendar file work in access 2007?
I have an Access 2010 database with two tables and two forms. The tables are Organizations and People. Similarly, the forms are Organizations Entry Form and PeopleEntryForm. The People are linked to the Organizations table. Several people can be linked to the same organization.On my Organizations EntryForm, I created a command button to duplicate a record using the wizard. It works fine.
I did exactly the same thing on the PeopleEntryForm, but instead of copying the record, it creates a new blank record. I don't get any error messages. Is my problem due to the fact that the People table is linked to the Organizations table?
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.
I am trying to change the button color on a subform if a related form data changes.Main form is products with a continuous subform with serial numbers of products i.e, serial number, location, price and a button to add addtional issues if there are any for this particular serial number (this will open up another form related to the serial number so I can add an issues if there are any).The reason I would like the button to be a different color is so I can quickly see if there are any additional notes been added to the serial number. Just in case you may ask why not add the field to the continuos form is that the issues and be quite lengthy and there may be lots of serial numbers on the form
I have not done much work in later version of Access. Now I found if I change a design in one form and similar forms (names are different) which are linked to the same tables got changed as well without openning them up and making changes. Is this something new with Access 2003?
