I've put in -100 as an arbitrary never possible number. Obviously, this does not return Null values.
Question: How can I return both Null & Numbers when the Textbox in the form is left blank? in all the columns. Currently, I am not getting Null values
Code:
>IIf(IsNull([Forms]![MainForm]![Criteria]),SHOW ME EVERYTHING INCLUDING NULL VALUES & NON-NULL NUMBERS,[Forms]![Material Finder]![txtPS])
or in other words
If the textbox is blank, show me all the data available, else if it is not blank then show me only the values that are greater than the number entered in the textbox from within column A, B, C, D ....
I need to make a query to compare equality of two pieces of data, one is a 6 character fixed-length text string (where the first character can be ignored) and the other is a 4 or 5 digit number (long integer, if 4 digit number can be assumed to be 5 with a leading 0).
I do not have the ability to change the way I receive the data, they are on linked tables of different customers.
I tried using various SQL functions to convert the data in the query but they don't seem to work in Access, so I am getting "Type incorrect in the expression" errors.
How do I do this in ACCESS? I would prefer a SQL query solution to a VBA solution if possible, the data is updated VERY often and the application is already doing too much processing on the form_timer() event.
I am making a report off of a query. The report is returning values from a Option Group. 1=Yes, 2=No and 3=N/A. The report returns the numeric values and I want the value labels instead. So, I created a column in the query for exp1 which looks like the following:
i have checked the forums and i know they kind of answer this question, but im not really sure where i am ment to write it!
I have two queries, which a third query subtracts the 1st query and 2nd query values and gives the end value. If the 2nd value is null, i get a null value at the end, as i need to change this to zero instead. i know i need to use nz (as seen in microsoft access help, and other places on this forum) but im not sure exactly where to put this on my query, and in which query.
I am trying to alter this parameter to bring back all records if either beginningsalesrange or ending salesrange is left blank. I can't quite get it right.
Between [forms]![frmState]![BeginningSalesRange] And [Forms]![frmState]![EndingSalesRange]
I have a table with two fields; Part and remarks - both Text fields containing 1.8 million records. Remarks field has 600,000 blanks in the field. I filtered for blanks to get the 600,000 records displayed. I want to update this field to N/A where null values exist. My code is
UPDATE PartApplications SET PartApplications.remarks = "N/A" WHERE (((PartApplications.remarks) Is Null));
The query updates 55,000 records ONLY and leaves the remaining blank.WHY would all null values not get updated?
i have 2 tables that i am linking on a field that matches with null values on both tables but it either pulls nothing or when i put a right join pulls just one tables data.
i have also confirmed both are pulling from the same data source, so no issues with field properties and confirmed they are null values in each field within both tables.
I'm having a problem with queries, and I can't seem to find a solution in books - I looked through about ten of them and none of them addressed the problem. This may be because it has a painfully obvious solution...
A little background: I am designing a database for a debt-collection law firm. One of the functions it must have is to keep track of various different sorts of financial transactions which can pertain to a given debtor (ie, a received payment, a cost expended, and a few other things).
The problem is that, in generating reports, I need to use queries to find several sums of only those transactions which fall into specific categories (for instance, to calculate the amount a debtor has paid against his balance, it needs to sum only those entries which are both linked to that debtor's ID number and whose type field reads "payment", and then subtract from that those entries whose type field reads "cost"). The problem is this: not all debtors may have "costs" entries, and when there are none, the report comes up blank with a single "#Error" written in the name field and nothing else present.
I believe the problem is that the Sum aggregate is returning a null value when the query finds nothing that meets the criteria. I have been unable to find a way around this; the Nz() and IIf() with IsNull() functions don't seem to be helping.
The query runs as intended when there are entries for every relevant type; however, it is undesired to have to enter a "payment" of $0, "cost" of $0 etc for every entry just so that this function works.
Is there anything I can do about this? Any input would be appreciated, as I'm fairly inexperienced with the use of Office Access. (If it matters, I am using Office 2003).
I am trying to use the expression below to transpose strings of 4-6 numbers (140504) to a string of 8 numbers with "20" in front (20140504). Some of the [Receive_Date] fields are empty or are 0, and in those cases, I need the expression to return a null value.
The Format(...) part of the expression works fine on its own, but I am new to dealing with null values in my expressions, and when I add the rest of the expression, all '#Error' values are returned.
I have a query that performs some calculations, these calculations feed into another query and produce a final value. If there are no null values everything works perfectly. But when there are null values, I get errors.
What I have tried:
1) I tried to implement the Nz function for each field of the formula that is not calculated but from user input.
2) I tried to implement the Nz function for just the field that calculated the last result before feeding into the next query, but it didn't show the 0 value I gave.
3) I tried to use UPDATE TABLE SET in SQL, but I don't think I was using it right. I tried to use it for all records but always got an error when it ran.
The first two above result in showing no values at all, even if there are some. The third didn't work. How to easily update null values in the query to 0? All I could think of was to somehow use Criteria or SQL.
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*"))
I have a calculated field (Bhours) with the following IIf function:
=IIf(Fields!BDate.Value<=Parameters!Pdate.Value and Fields!EDate.Value>Parameters!Pdate.Value,Fields!H ours.Value,0)
It works perfectly, but I don't like the fact that it has a zero for the false part as I like the field to the blanc instead of filled with a zero.I can't use a space as I need to calculate with this field later on. I tried using "", but then the field displays #error".
I am currently working on an instrument datebase, I have a mainquery that takes care of user inputs from a form. The main fields that have been queried on are Type, System, and Manufacturer and they are all look-up fields that contain some null values.
On the same criteria row for these fields, I have
Like IIf([forms]![User Interface].[qtype2]="","*",[forms]![User Interface].[qtype2]) Like IIf([forms]![User Interface].[qsys2]="","*",[forms]![User Interface].[qsys2]) Like IIf([forms]![User Interface].[qman1]="","*",[forms]![User Interface].[qman1])
qtype, qsys and qman are the user inputs from the user interface that returns look-up table values.
This works fine when all 3 of these fields are all filled out for a certain instrument. The problem arise when some fields of the instrument are left blank or is null. The instrument won't show up in a query at all. What I wanted it to do is to show everything including the ones with null fields when the user input are null or "". When the user specifies certain requirement I only want to show the ones that are not null. I understand that putting them on the same row means AND, I have tried to OR them and did not have the result i wanted.
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.
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]"))));
I have a query which returns, among other things, a number of boolean fields. In some cases, there will be a genuine True or False value in each of these fields; in others, it can and should be Null (e.g. as a result of a 'failed' LEFT JOIN of some description, where there is no associated record in the joined table which fulfills the criteria)
So something like this :
Code: SELECT [tblTable2].[fldBooleanField].... FROM [tblTable1] LEFT JOIN [tblTable2] ON [tblTable1].[SomeID] = [tblTable2].[SomeID]
However, I will be writing the result of the query to a text file and here's the problem. I want to show a numeric value for a genuine True / False (i.e. -1 and 0 respectively using the standard boolean conversions in Access) and a blank for any Null values.
So I tried this :
Code: SELECT CInt([tblTable2].[fldBooleanField]) AS fldBooleanField.... FROM [tblTable1] LEFT JOIN [tblTable2] ON [tblTable1].[SomeID] = [tblTable2].[SomeID]
However, currently when I look at the exported recordset in Notepad, I am getting 0's for both False and Null values (and -1 for True)
How I can adapt my query to keep Nulls...null? And convert the genuinely present boolean values to integer form?
Only thing I can think of is to use (untested) :
Code: IIf([tblTable2].[fldBooleanField] Is Null, Null, CInt([tblTable2].[fldBooleanField]))
But there's a number of boolean fields in there, all requiring the same treatment.
i'm creating a search form giving the end user a range of controls to use when filtering/searching data. See the image.But, i think my range search (using the textbox) to put in a lower and upper limit...is preventing this from working. In fact, when i put data into all the controls, no data pops up in my subform.
My query data source can also be seen...showing you how i've handled teh null entries. (i need to put in a null 'handler' for the two textboxes?)
I have a field called PRICE and obviously it is a NUMERIC field as it need to perform calculations such as calculating Total Quantity * Price etc. At the moment the PRICE is inputted manually by the User on a Form and when it has no Price it is simple left blank.
What I wish to include is that on the REPORT when the field is empty it writes the text FOC instead of leaving it empty.
Can you please anyone suggest a way of doing this.
I have a travel time database that should tally the number of minutes traveled and convert them into a time (hours and minutes). I, however, am having difficulty converting the numeric values cleanly. Is there anyway to convert 102 minutes + 100 minutes + 110 minutes = 312 minutes to 5 hours and 12 minutes cleanly? I need to take averages of time traveled and hours worked but cannot do this correctly. Thank you for any help in advance.:eek:
I am new to this forum, and I am facing a problem while learning MS-Access.
I am preparing a database that stores the marks obtained by students in a particular paper in addition to their particulars in tables. A query is then generated to canculate the aggregate marks and result (Pass/Fail) for the student. It is then presented in a report fomatted as a marksheet, as well as one tabulation chart.
The database is very crude in format, but I am happy with it since I do not know programming at all, and still I could make it. I have used in built menu of "ms-access" and mouse clicks only for generating query. It was a learn by doing method.
The problem is that my marksheets require absent students to be marked as "ABSENT" or something of that kind. If I convert my Null values to :
Expr2: IIf(IsNull([E_1]),"ABSENT",[E_1])
It shows ABSENT for null value, but refuses to make column total for E_1; On the other hand if I do not enter such expression, it makes column total in tabulation report, but fails to mark "ABSENT" to those who did not appear. So I have to lose one thing to gain another, while I need both.
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
I have found a SQL Query I have tried to use, however I am having no joy. The query is such:
WITH rows AS ( SELECT *, ROW_NUMBER() OVER (ORDER BY VisitID) AS rn FROM Data ) SELECT DATEDIFF("n", mc.EndDTM, mp.StartDTM) FROM rows mc JOIN rows mp ON mc.rn = mp.rn - 1
