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'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 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?)
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 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 want query to show all results including any null values because at the moment it just misses the null values out.
So for example instead of the query saying that Fruiterer A has 5 apples, 0 oranges and 4 bananas it just says that Fruiterer A has 5 apples and 4 bananas. Therefore because oranges was a null value then it simply makes no reference to oranges.
I have two tables called table1 and table2 with following fields:
Table1: Name NameId
Table2: Name NameID Visits
where name and nameid is same but visit can me 0 to 230. name in table2 is same as table2 but only showing visit 1 or higher. How can I make new table that can list all name, nameId and visits.
I can create new table but it shows only table2's record. so all I need is table1 and table2 record if names are missing in table2 then put 0.
Hi all I have 3 linked tables in a vehicle database. 1 keeps a record of Service Due date, 1 has the Fleet numbers and the last contains Vehicle Condition reports. They are linked by the Fleet numbers. I have a query that returns the Services due between 2 dates. What I would like is to have the same query return any outstanding Vehicle Condition items as well for any Vehicles due for servicing. Currently, I can include the field in the query but if there are no current items for a vehicle in the Vehicle Condition table then the query does not return that vehicle as a result. Any suggestions would be appreciated.
Now I want to count the number of sales completed from these totals. However, as Dept 3 has no sales completed for October it does not show in the query. So I get
Dept 1 - 7 Dept 2 - 2 Dept 4 - 6
Any idea how to get Dept 3 - 0 to show up in the query?
I've found several threads on this subject, but I still can't get it to work, so please forgive me if I seem to be duplicating a question.
I'm making a very simple db. It has only 2 tables: MATERIAL (one) TEST RESULTS (many) with left join.
I need to report average test results (by MATERIAL) weekly, even if there were no tests for a particular product that week, ie;
MATERIAL A = 100 MATERIAL B = 90 MATERIAL C = MATERIAL D = 105
When I try to query, I only get results for A, B and D. It seems to be ignoring the MATERIAL table and looking only at the TEST RESULTS table.
I'm sure it's something simple that I'm overlooking but how do I get C to show, even if it has no results.
Here's my query SQL.:
SELECT DISTINCTROW [MATERIAL Query].MATERIAL, Avg([TEST RESULTS].V50) AS [Avg Of V50] FROM [MATERIAL Query] LEFT JOIN [TEST RESULTS] ON [MATERIAL Query].MATERIAL = [TEST RESULTS].MATERIAL WHERE ((([TEST RESULTS].[TEST DATE]) Between [Forms]![Date Range Form]![Start Date] And [Forms]![Date Range Form]![END DATE])) GROUP BY [MATERIAL Query].MATERIAL;
I am trying to build a query that combines several fields. The situation is as follows....
1. If a is > b then i need a 2. If b is > a then i need b 3. If a is null then b is not null 4. If b is null then a if a is not null 5. If a and b are null then '999999'
I have everything taken care of up to If 4. The problem i am having is that when create the sql language for 5 it is adding 999999 to the filed when step 3 or 4 are the case. See languange below.
Any help would be greatly appreciated.
IIf(MSC.[TDS<2500_S_GW_NR_100xGWMSC_mg/kg]>MSC.[TDS<2500_S_GW_NR_Model_mg/kg],MSC.[TDS<2500_S_GW_NR_100xGWMSC_mg/kg]) & IIf(MSC.[TDS<2500_S_GW_NR_Model_mg/kg]>MSC.[TDS<2500_S_GW_NR_100xGWMSC_mg/kg],MSC.[TDS<2500_S_GW_NR_Model_mg/kg]) & IIf(MSC.[TDS<2500_S_GW_NR_100xGWMSC_mg/kg] Is Null,MSC.[TDS<2500_S_GW_NR_Model_mg/kg]) & IIf(MSC.[TDS<2500_S_GW_NR_Model_mg/kg] Is Null,MSC.[TDS<2500_S_GW_NR_100xGWMSC_mg/kg]) & IIf(MSC.[TDS<2500_S_GW_NR_100xGWMSC_mg/kg],MSC.[TDS<2500_S_GW_NR_Model_mg/kg] Is Null,'999999') AS MSC_SGW
I have a series of values within a table that includes a number of null values. I would like to include this field within a query, however if the value is null I would like to show a 0, if the field is not null, I would like it to show the original value.
I have tried to use the IsNull in an iif formula without luck.
PS: If I was conducting this in Excel I would use the following =IF(J3="",0,J3)
I have a query set up to sum 2 fields to a 3rd field, for example, I have field1, field2, and field3. Fields 1 and 2 are data from a table. In Field3 I have an expression: Field3: [Field1] + [Field2] This works fine except when either Field1 and/or Field2 contain no data, then the sum does not work. Any ideas how to correct this? I realize this may not be the best way to accomplish what I am trying to do but this is a small part of a very large application and i would like to change as little as possible since everything else is working ok. Thanks very much.
