Null/empty Field Count
Nov 30, 2007
I have the query below and it returns the number of cases for eache of the case status (open, closed or private) Some of the cases have no status, the field is empty. Is there a way to count the number of cases which have no status in the status field?
Can someone tell me how to do this?
SELECT
Count([Report table part one].CaseStatus) AS CASES,
[Report table part one].CaseStatus AS STATUS
FROM [Report table part one]
GROUP BY [Report table part one].CaseStatus;

In a previous post someone mentioned a difference between Null and Empty. Is Null is not pulling the nulls but I know those fields are empty. Can someone tell me how to pull in these empty fields. for my calculation I need to get Companies that showed revenue after and didn't show revenue once their contract started.
Thank you

I have the following problem:
I have a make table query that sum a total amount in order to have only the total in the table field.
However, when the total is 0.00, the make table query says "you are about to pos 0 rows" instead of postin 1 row with 0.00.
How can I set the query in order to have a 0 in the table when the total is 0 instead of having nothing posted ?
I have tried the is null, is empty, is missing, nz and nothing seems to work.

I have a form, form1. Inside there is a combo box, cbo1, that gets its values from table1.On form load, I want an expression that checks if table1 has any values to "send" to cbo1. If yes, meaning, if after form loads cbo1 is loaded with table1's values, I want cbo1 colored RED, if not, colored WHITE.

I have a module that creates records into a contacts table in my access database. When there is no data in the field from outlook, the data is populated as an empty string "" instead of a null value, creating problems with subsequent queries and processes. I'd like to create the data as a null value but the module keeps failing with "object is required" on the statement
rstImport("Customer ID").Value = System.DBNull.Value
It doesn't seem to like System.DBNull.Value or DBNull.Value, and when I assign the vbNullString constant instead, it gets set to "" again and not null.

Im trying to concatenate a bunch of fields (50 arghh) which each are either blank or just contain one letter. This was someone elses setup for an attendance register which I think is an odd way of doing it. I would have used one field and then to get the mark for a week take a substring at the appropriate position. Anyway im trying to replace an empty string field with a letter to represent the register hasn't been marked using sql statement:
SELECT [400 Student Marks].acad_period, [400 Student Marks].student_id, [400 Student Marks].register_id, [400 Student Marks].register_group, Replace([1],"","U") AS attendance
FROM [400 Student Marks];
[1] being the first register week then I would have concatenated with [2] etc...
This however causes an error each time on the attendance field so im guessing replace doesn't work on empty strings. Is there a way round this/alternative.
Thanks for any advice.

a table which has several fields (ProjectID, Name, PM, Category, Date, Tester).
I am trying to find a way to count how many of the fields have been filled out and how many are null for a particular Project ID.
For example, ProjectID=27 has a Name and a PM but no more data so when I load the form I want the db to tell me 3 of the fields have been filled out for this project. This way I can calculate how many are empty (3 in this case)
How would I go about doing this

I 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?

Hi
Been taking abreak from Access for a few years now and cant get my head round my problem.
I have been asked to manipulate data from a Training Recods database.
Basically, training consists of 26 modules, there are currently 180 people who need training. Each person has been assigned a unique number, once a module has been completed, the date it was completed is entered into the database. There are currently lots of modules which havent been completed, what I need is a way of pulling that data from the DB.
I need to know how many people need to complete each module. For example, Module 1 might need to be completed by 15 people, Module 2 might need to be completed by 27 people etc.
I have enclosed the DB with the table and the form that I am looking to populate with the data.
Anyone have any ideas, I just can't get my head round it!!!!

Hello,
I am using the following code to count records in a table:
Dim myCount
'Looks the data with criteria 1 in table
myCount= Nz(DCount("[Myfield]", "[mytable]", "[myfield]='1'"), 0)
'Returns sum in text box
Me.[txt1] = myCount
My table will also contain no records in the myfield. Is there a way I can count null values? Thanks.

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).
When I run the query I receive
The query returns this:
2000 Westside 6
2001 Westside 3
2003 Westside 1
2004 Westside 3
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));

I have a count column in this query, and i would like for it to return a zero instead of null if it doesnt find anything to count. Here's the SQL for the query.
Code:
SELECT Documents.Status, Count(Documents.Document) AS CountOfDocument
FROM [Request Details] INNER JOIN Documents ON [Request Details].Request_ID = Documents.Request_ID
GROUP BY Documents.Status, [Request Details].Contract, [Request Details].CDRL, [Request Details].Change_Cycle
HAVING (((Documents.Status)="No Record") AND (([Request Details].Contract)=[Forms]![Report Runner]![Contract]) AND (([Request Details].CDRL)=[Forms]![Report Runner]![CDRL]) AND (([Request Details].Change_Cycle)=[Forms]![Report Runner]![ChangeCycle]));

I am trying to create a clean database and code to generate a report.
I am trying to count the number of null fields in one of my queries:
However, because of this expression, I cannot carry other fields with it. So the end result looks like:
But I would really like it to spit out the following information:
Total Not Fixed: 241
Department: Sustaining Eng
is there a way to create an SQL query to simply add data: I have tried the following:
Code:
ALTER TABLE qrySustainingEngNotFixed2 ADD Dept TEXT(25)
Insert Into qrySustainingEngNotFixed2 (Dept) Values (Sustaining Eng)
SELECT TotalNotFixed, Dept
FROM qrySustainingEngNotFixed2;
The above isn't working. Keep in mind that I want this is just for display purposes. I pondered making a custom table and then making a Union Query, but I'm trying to do this all in one SQL statement.

Hi all,Desperate for help on this.The query below ran like a charm for this years database which was full of entries, but when I did a quick test run for next year with limited entries the 'Temp' table fields were all blanked. All the individual queries, 1 through 9, work fine on their own and work fine in this linked form when there is enough data in the database to cover all the fields. Apparently if only one query is blank all the fields will be blank.For instance if there are multiple registered households, table ‘1’ would normally show a count of those households, but if none of those households have children, table '2' which counts children will be blank and in turn blank out all the rest of the fields including table ‘1’.I've tried the ‘is null, '=0" and ‘nz’ routines on the Count(Tablename.Fieldname)'s, but can't seem ‘to get them to output a value of 0 in the null fields. I must be doing something wrong. Any and all help would be very much appreciated.SELECT Year(Now()) AS ProjectYear, [1].CountOfClaimID AS Households, [2].CountOfPersonID AS Children, [3].CountOfPersonID AS Participants, [4].CountOfSponsorID AS SponsorsTotal, [5].CountOfHouseholdID AS Sponsored,[6].FamiliesWithChildren, [7].SponsoredFood, [8].SponsoredGifts, [9].SDSD INTO TempFROM (SELECT Count(Household.ClaimID) AS CountOfClaimID FROM Household GROUP BY Household.RegStatus HAVING (((Household.RegStatus)=-1))) AS 1, (SELECT Count(Members.PersonID) AS CountOfPersonID FROM Household INNER JOIN Members ON Household.HouseholdID = Members.HouseholdID GROUP BY Household.RegStatus, Members.Status HAVING (((Household.RegStatus)=-1) AND ((Members.Status) = "Child" ))) AS 2, (SELECT Count(Members.PersonID) AS CountOfPersonID FROM Household INNER JOIN Members ON Household.HouseholdID = Members.HouseholdID GROUP BY Household.RegStatus HAVING (((Household.RegStatus)=-1))) AS 3, (SELECT Count(Sponsors.SponsorID) AS CountOfSponsorID FROM Sponsors GROUP BY Sponsors.SponsorStatus HAVING (((Sponsors.SponsorStatus)=-1))) AS 4, (SELECT Count(Sponsorship.HouseholdID) AS CountOfHouseholdID FROM Sponsors INNER JOIN Sponsorship ON Sponsors.SponsorID = Sponsorship.SponsorID GROUP BY Sponsors.SponsorStatus, Sponsorship.SponsorshipYear HAVING (((Sponsors.SponsorStatus)=-1) AND ((Sponsorship.SponsorshipYear)=Year(Now())))) AS 5,(SELECT Count([Table0].HouseholdID) AS FamiliesWithChildrenFROM (SELECT Households_All.HouseholdID, IIf([Children]>0,1,2) AS FamChildrenFROM Households_AllGROUP BY Households_All.HouseholdID, Households_All.ChildrenHAVING (((IIf([Children]>0,1,2))=1))) as Table0) AS 6,(SELECT DISTINCT Count(Household.HouseholdID) AS SponsoredFoodFROM Household INNER JOIN Sponsorship ON Household.HouseholdID = Sponsorship.HouseholdIDGROUP BY Household.RegStatus, Sponsorship.SponsorshipYear, Sponsorship.FoodHAVING (((Household.RegStatus)=-1) AND ((Sponsorship.SponsorshipYear)=Year(Now())) AND ((Sponsorship.Food)=-1))) AS 7,(SELECT DISTINCT Count([Household].[HouseholdID]) AS SponsoredGiftsFROM (Household INNER JOIN Sponsorship ON [Household].[HouseholdID]=[Sponsorship].[HouseholdID]) INNER JOIN (SELECT Households_All.HouseholdID, IIf([Children]>0,1,2) AS FamChildrenFROM Households_AllGROUP BY Households_All.HouseholdID, Households_All.ChildrenHAVING (((IIf([Children]>0,1,2))=1))) as Table0 ON [Household].[HouseholdID]=[Table0].[HouseholdID]GROUP BY [Household].[RegStatus], [Sponsorship].[SponsorshipYear], [Sponsorship].[Gifts]HAVING (((Household.RegStatus)=-1) AND ((Sponsorship.SponsorshipYear)=Year(Now())) AND ((Sponsorship.Gifts)=-1))) as 8,(SELECT DISTINCT Count(Household.HouseholdID) AS SDSDFROM HouseholdGROUP BY Household.RegStatus, Household.SDSDHAVING (((Household.RegStatus)=-1) AND ((Household.SDSD)=-1))) as 9; Thanks much,aldo

I have a table tblBookings.
In this table it has a bookingID, CustomerID and some other none relevant details.
The CustomerID comes from table tblCustomer. i.e a customerID must exist in the customer table to be allowed in the bookings table tblBookings
A customer can exist in tblCustomer without existing in the booking table.
I am trying to write a query that will list each and every customer ID in the tblCustomer and count the number of bookings that that customer has (even if it is zero).
I have a query that will count the bookings if they exist in the booking table and display the number of times that a customer appears in the bookings table.
SELECT tblBookings.CustomerID, Count(tblBookings.CustomerID) AS NoOfBookings
FROM tblBookings
GROUP BY tblBookings.CustomerID;
How do I create a query that will do this but list all customers even if they don't exist in the bookings table (but obviously occur in the customers table)
I am trying to create a similar query where all bookings per hotel are listed even if no bookings are made for that hotel. I am guessing the answer is the same as above.
The Ritz. Bookings 0
The Hilton. Bookings 3
The Carlton. Bookings 0
The Lowry. Bookings 2
For every hotel.
That kind of thing.
If you need more information please shout.

I am trying to make a query with two tables. Each row consist of a student ID, their name and all their personal information. Both tables are exactly the same. But one table is a link table. That link table gets update every so often from an outside program and the other table is not linked. I want to be able to run a query that updates certain fields called "address changes". I have figured out how to find the updates, but I am having a problem with a field that is blank. If I have a field in the non-linked table that is empty but there is information in the linked table, it does not see it. Is there a way to get around this empty field problem?
