Exclude Null Values In Query
Dec 21, 2004
I have made a query from a table to count something.
Now, I dont know how to exclude the null value to the new query.
example:
Query Name: School
Field: Sch_No, Sch_Name, Subject1, Sum1, Subject2, Sum2, Subject3, Sum3, Subject4, Sum4, Subject5, Sum5
After run this query, there is a field(Subject4) has a null value.
Before I make a nice report, I have to exclude Subject4 & Sum4. And this will make Subject5 the fourth subject without displaying Subject4 & Sum4.
I hope anybody can help me..i dont know how

I'm trying to create an expression to calculate percentage.
The fields, Value A and Value B might both have null values, but I do not want Access to treat nulls as zero (as in the Nz() fn). How do I get the expression to exclude any nulls and not calculate for those rows, but set the calculated value for a row with null A or B to zero.
I want it to set no calculated value to zero so I don't get overflow errors and can therefore order the data by the calculated field.

I need to create a query with the MTD field
I have created the MTD and it works!!! but now I need it to show all of the PartNum fields even if null. do I need to convert all nulls to zeros? if so how do I go about this?
Here are the fields in the query
First Field:
Field: PartNum
Table: Part
Total: Group By
Second Field:
Field: UnitPrice
Table: OrderDetail
Total: Group By
Third Field:
Field: NumOrdered
Table: OrderDetail
Total: Sum
Fourth Field:
Field: MTD: Sum([NumOrdered]*[UnitPrice])
Table: (blank)
Total: Expression
Fifth Field:
Field: CurrentYear: Year([OrderDate])
Table: (blank)
Total: Group By
Criteria: Year(Date())
Sixth Field:
Field: CurrentMonth: Month([OrderDate])
Table: (blank)
Total: Group By
Criteria: Month(Date())
When I run the query I only get 2 parts and their total. but I want all parts to show up even if they have not been ordered in the month. the parts that have not been ordered should say $0.00 in the MTD field.
Any Suggestions???

Hi,
I have a problem with one of my query, the query has 2 tables, the secondary field from Table2 is linked to the primary field of table1.
The primary field Doesn't allow null Value
The Secondary Field does allow null value which means that the Data in table 1 only concern Some of Table2's Data.
If I run the query with the two tables I can only see the records with the secondary field with no Null Value.
Is it possible to get the query Showing All the records of table1 2 and Table1 even if Table1 has no values?

Have the following scenario with perhaps inbuilt fatal flaw
Building an Inventory Management db and in the process of constructing the tools to move some inventory from 1 location in the warehouse to another (purely an internal transfer)
Part of my table design includes an allocated quantity field to record any outstanding orders for this inventory unit (I am planning on a built in LIFO system, which I haven't got around to contemplating yet)
All went well, the stock was decreased from the existing location using an update query. but failed to materialise in the new location using an append query
After much yelling and cursing at the offending query, finally did a search and found the following:
Update queries will not work if you trying to append a primary key value (knew that one) OR you are trying to append a null value into a field
In the real world, it may well be possible that I will have 0 allocations for a given inventory unit
Does anybody know a way around this seeming impass, or am I faited to rebuild my tables again?
Thanks in advance for any enlightenment

2007 version - my child query is not returning null values. I have 2 fields, both pulled from a parent query. One is "DaysSinceRecd", the other is "AmountPaying". The parent query returns multiple results, which is fine. For example, the parent query might have 10 different records for "0" "DaysSinceRecd", with different "AmountPaying" for each of those records.
In the child query, I am trying to condense that down, so that I only have one "AmountPaying" for each "DaysSinceRecd". It's working fabulously, except that there are records in the parent query that have a value for "AmountPaying" but a null value for "DaysSinceRecd". The null value for "DaysSinceRecd" cannot be changed to another value, it needs to stay null. My child query is not returning the null records. I tried adding to the criteria: IsNull Or IsNotNull, >=0 or <=0. That's not working.

I have two tables: tblStudents and tblEnrollments. The query I have designed shows the StudentID and counts the number of Enrollments that each student has. I want the students who don't have any enrollments to still show up and have a 0 by their ID. Right now, only the students with enrollments show up in the query results.
Here is my SQL Statement:
SELECT tblStudents.StudentID, Count(tblEnrollments.EnrollmentID) AS CountOfEnrollmentID
FROM tblStudents INNER JOIN tblEnrollments ON tblStudents.StudentID = tblEnrollments.StudentID
GROUP BY tblStudents.StudentID;
What do I need to do to it to have null values display as zero?

I have a form with 4 different search fields used to query a table and limit results: Policy#, SSN, Credit_Amt, Debit_Amt. Any matching rows based on the search criteria are returned in a subform.
My problem is how to handle any fields where the user doesn't specify a search value.
In my query, I have the Criteria set to:
Field: Policy_No
Criteria: =[Forms]![form name]![Policy#]
Field: SSN
Criteria: =[Forms]![form name]![SSN]
and so on....
If I place my criteria on different OR lines, the query runs, but if a user specifies more than 1 criteria, I get all the data for one criteria(such as policy# matches) and all the data for the second criteria(such as all the records for a certain credit_amt, regardless of Policy #).
If I place my criteria on the same criteria line, effectively making it AND, I get no results because I assume the database is looking for any blank search field values.
So, how do I make the query an "AND" query, but actually get results by ignoring any NULL search fields? So if a user enters a Policy# and Credit_Amt, the results will be only matching rows by Policy# AND Credit_Amt, and doesn't look at SSN and Debit_Amt.
I've tried different iterations using IIF(Not IsNull(.... to no avail.
Thanks!

Hi,
This query will allow me to view payments that are made between 2 dates. I would like to know how to flip the query around so that it gives me the payments that have not been made. I think this would be described as returning the null values?
The SQL code i have at the momnet is:
SELECT download20060602.Date, download20060602.Description, download20060602.Amount, Members.FirstName, Members.[Mid Name], Members.Surname, Members.[Memb No]
FROM Members LEFT JOIN download20060602 ON Members.description = download20060602.Description
WHERE (((download20060602.Date) Between [Enter Start Date] And [Enter End Date]));
Any help or ideas would be fantastic.
Cheers
Phill

Hi there.
I've attached my db in the hope someone can help my head scratching.
I have got a Sales summary table with several other related table. Most notably, a table with the items in the sale and one with the costs. Because each sale might contain many different items and many different costs, I thought seperate tables were the way to go.
All I'm trying to do is make another query that gets the total sales (That's adding each line item * quantity) - (Each cost line item*it's quantity) and then finally the margin made on the deal.
However, if there are no costs or sales involved in the sale the query ignores it. (Sounds odd, but some transactions might be cost free, and some may not involve any revenue - so I have to bear it in mind).
I tried the Nz function, but It's either not what I need or I'm doing it wrong.
How do I get this to work?
Many, many thanks!

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.
Is it not allowing Null records?

I am currently creating an Access 2007 database for calculating salesperson commissions. I have a table with 5 fields I'm working with: SalesRep, SOWRep, TerritoryRep, Period and Commission. I am trying to build a query that will calculate commission for a salesperson for each record where their name appears in one of the first three fields. Each time their name appears, they get the commission listed in the Commission field for the stated Period. I have managed to do this part successfully. My problem now is that I am creating a query that will sum all of their commissions by Period. I have run into a situation where sometimes a salesperson will not appear in one of the rep fields, resulting in NULL values in the previous queries. How can I create a final query that will sum correctly even if there are NULL values returned on the previous queries?
Here is what I have so far:
November: Avg((SELECT [SumOf1/3GM$s] FROM [BaxterActualMargin1] WHERE [Period] Like "November*")+(SELECT [SumOf1/3GM$s] FROM [BaxterActualMargin2] WHERE [Period] Like "November*")+(SELECT [SumOf1/3GM$s] FROM [BaxterActualMargin3] WHERE [Period] Like "November*"))

NOTE: Im working in MS Access 2003, only results in this SQL/database (not mysyl, MSSQL etc)
I want to be able to ORDER an SQL query and put the NULL values last.
I have a basic databse:
Table name: PeopleTable
Field names: TableID, PersonField, PersonID
The aim is to order by PersonID and put the NULL values last
See pic1.jpg;
The picture (pic1.jpg) shows the database as it is without a query.
See pic2.jpg;
Picture 2 (pic2.jpg) shows the query results when I use the orderby statement (SELECT * FROM PeopleTable ORDER BY PersonID As you can see it shows the results ordered by the PersonID however the NULL values are first.
See pic3.jpg
Desired results, it is ordered by the PeronID and the NULL values are last (NOTE this is an editied screenshot).How can i achieve this is MS Access 2003?

how to return all values in a query when a form critieria is left blank. I have made some progress, the combo box criteria queries were fairly simple, but i'm getting stuck with my date criteria. My query doesn't return null values when I want it to.
I want it to return all records (including null values) if the form OpenFrom and OpenTo dates are blank, and just the values between the selected dates (excluding null values) if the form is completed.
Code:
SELECT qryReportSelector2_Authority.*, qryReportSelector2_Authority.ApplicationDate AS ApplicationDateFilter
FROM qryReportSelector2_Authority
WHERE (((qryReportSelector2_Authority.ApplicationDate) Between Nz([Forms]![frmReportSelector]![OpenFromDate],DMin("[ApplicationDate]","[qryAllCases]")) And Nz([Forms]![frmReportSelector]![OpenToDate],DMax("[ApplicationDate]","[qryAllCases]"))));

Hello I am new to this site as well as MS Access and SQL. So any help would be appreciated. Sorry if this is too drawn out. I have this query that returns the previous business day's(Monday through Friday) number of docs sent from my department to another department. I would manually go into the SQL view in Access and change the date to yesterday. The easy part was having the code do the previous day. The problem comes Monday morning when the code does the previous day. It will do Sunday which will return nothing since I really want Friday's numbers. I am trying to figure out how to take into consideration if the query is run on Monday morning and to automatically choose Friday. I checked out DayOfWeek() and Case When condition statements but really unsure about syntax and whatnot. Here is the SQL view of the query...

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?

I made a query to calculate the average of a column, suppose that I have 5 records in that column (46,35,0,19.3,12), when the query calculate the average it sums the total of the column and divide by 5 (that's 112/5 = 22.4), what I need the query to do is to divide by 4 because one record is zero (that's 112/4=28). I put in the criteria the following (Not Is Null And <>0), yes this will not show the column that has zero but it still divide by 5.

I've created a query where I am searching a database of job titles for contacts that are considered senior management.
One criteria I've entered into a query is as follows:
Like "*Vice*"
Which is meant to identify anyone with "Vice" in the title. The problem is I have noticed this also returns records with "service". So can I edit this query to specify that the "V" must be capitalized? I think this would serve.

Hi,
I've been searching the forums, and I find a bunch of posts about the subject, but I just can't seem to really find what i need.
What I'm looking for is how to construct a query, that will exclude any entries in my table that might fall on a Saturday or Sunday.
What is the easiest way to do this?
I'm going to be using the results of this query in a Report and DAP.
Thanks

I have a simple dbase that lists individual staff members' qualifications, skills and hobbies.
One person may have 20 qualifications and another may have 1 or none.
I have a separate field for each qualification.
Is it possible to write a query that only returns fields that are not null in each record so that the subsequent report is not full of blanks? I know I can use Can grow - Can shrink on the report but I'd rather eliminate blanks via a query if I can.

I have a difficult problem (because of my own capabilities). I have a table (tblFoods) which includes a number of food with their analyzes. I have a second table (tblExclusiveFoods) which is connected with a third table (tblCustomers) with one-to-many relation. Namely, o tblCustomers is the "One" and tblExclusiveFoods is the "Many".
Into table tblExclusiveFoods there is a field that acts like a ComboBox and gets data from the tblFoods such as drop-down-menu. So, using the combo box i can select the foodID from tblFoods and then showing into exFood field which is a part of the tblExclusiveFoods fields. When i collect the foodID's from the tblFoods, i would like to to build a query which will exclude these foods from the tblFoods.
