Forms :: Record Availability Of Volunteers For Different Events In Database
Jul 14, 2013I am trying to create a database that will record the availability of volunteers for different events.
So far, I have used access to create an availability table, that contains fields for event, date, name, shift 1, shift 2, shift 3.
I now want to create a form that will filter this table for a given event, then layout the form so that names appear down the left, date across the top, and then the shift 1 to 3 fields (which are yes/no fields) to appear in the body of the layout.
This is so the organising team can quickly enter this information (received by phone, email, fax) into the database. I have had a go with subforms within subforms but so far drawing blanks.

Selecting Current Assignments
Jul 6, 2005Help please. I have a database with patient authorizations to various providers. They may have more than one authorization on the same day. I need to select the patient and the most recently assigned provider (other selection criteria will also be used). Data may look something like:

If A Make-table Query Result Is Null, How To Have A Default Message Appear In Table ?
Jan 21, 2005Hi everybody,
Beginner here needs help !
I'm building a make-table query for which if the result is null (no record correspond to the set of criterias), a default message like "there was no activity during the period" would appear in the table (not a message box...I need the message in the output table). The best I could think of is an IIF function but it doesn't seem to work... Is there any way to do this without using VBA?
Thanks in advance !

Related Consultants And Assignments Based On Dates
Mar 26, 2007In my database I have:
* A table of consultants
* A table of contracts
* A table of assignments (shows which consultants are assigned to which contracts, along with the start and end dates of those assignments)
* A table in which consultants book their time to projects
The consultant assignments change over time. What I need to do is create a query that shows a) the amount of time a consultant booked to a project(s), and b) the contract to which he/she was associated at the time. For example, if a consultant was associated to Contract A in February, Contract B in March, and Contract C in April, I want to be able to accurately reflect that in my query. I'm not sure how to go about doing this in my query.
I'm sure many here have solved similar problems, so any help you can give will be appreciated.
Query With Is Null Returning Not Null Records

Thanks.
Queries :: Filter Data From A Table Using Query (from Data Input Form)
Dec 30, 2014I would like to filter data from a table using a query (from an data input form). The objective is to output all results if input form field is empty and to output results higher or equal to the type in the field if field is not Null. The query code is as follows:
IIf(IsNull([Forms]![Form2]![MaxDiffInput]);[Maximum operational pressure (bar)];[Maximum operational pressure (bar)]>=[Forms]![Form2]![MaxDiffInput])
However, is not providing any result when the input field (MaxDiffInput) as a value.
Changing Data In Query Results Changes Data In Source Table
Dec 17, 2012I have a table and a simple query that pulls results from the table. Nothing too crazy. But, if I were to go in and change some of the data/values in the query results it will change the respective data in the table. I know that this cannot be right. What do I have to do to either prevent the ability to change query results and/or prevent any changes in the query from altering the original data in the table.

Tables :: Transfer Data From Table Or Query To Second Table
Apr 25, 2014Let's say that there're 2 workers: Worker A, and Worker B, and they are fixing some engines. There's 2 different engines: Engine A, and Engine B. And these workers are fixing these engines for all day, and in the evening they have to register how many engines they've fixed.
And my job is to design Access database for them. I thought it will be very easy to do; I've created table with columns: Date, Worker, Engine, Quantity - so every day Worker A and Worker B can register, that they have repaired some amount of Engines A and Engines B.
But there's a problem that I also have to register how many Engines have arrived to the factory, and how many of them weren't repaired on time (E.g. 15 Engines A have arrived, Worker A fixed 5, Worker B fixed 5 so there's 5 engines left for tomorrow)
I've figured out that I should somehow create table IncomingEngines with columns Date, Engine, Incoming, Fixed, Undone (field Fixed should be completed automatically every day for every engine - it would be a sum of engines A and engines B fixed by worked A and worker B - so I could fill Incoming field manually)
It's easy to create this kind-of Query, but I can't add column to querry, or edit it.
If Data Is Null Change To A Different Formula
Aug 31, 2004Can 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.
THANKS!

Reports Show No Field Data If Value Is Null
Oct 6, 2006I have a question about reports in Access. Is there a way for report fields to be omitted from the report if the database value is null?
For example:
Name: Joe
Last Name: Smith
Company: (Is Null)
website: something.com
would become.....
Name: Joe
Last Name: Smith
Website: something.com
thanks!

View 2 Replies View RelatedQueries :: Export Query To Excel Then Delete Query Data From Table
Nov 20, 2013I am wondering if there is a quicker way to export a query to excel then have the data in that query removed from the original table. (effectively cutting the data from the table and exporting to excel)
I understand that this can be done by exporting the query to excel then running the same query as a delete query to remove the data but I just wondered if this is the most efficient way.
I have experience of VB in excel but currently only use the basic macro builder in Access though if Access VB is more efficient I can easily learn.

You Tried To Assign The Null Value To A Variable That Is Not A Variant Data Type. (Er
Jul 1, 2007Hi,
I am getting this error 'You tried to assign the Null value to a variable that is not a Variant data type. (Error 3162)' I know why I am getting the error, I found out that Form and Subform should be implemented only with one-to-many relationships where the Subform is the many end. However, I have the opposite of that for a reason.
Is this bad practice? Is there anyway around it or to fix the error please?
Any help will be very much appreciated,

Insert Null Values Into Date And Integer Data Type
Sep 22, 2006Hello guys,
Does anybode has any idea, of how to do that ? I can do it very easy in VB.NET, or C#, but in Access I give up.
So, I have to take data from the form , and send it to Sub.
With data type of String , I have no any problem, use Nz funciton, end everything, goes well.
But with Date and Integer, I can not find solution.
So :
Date
Dim PensionerFromDate as Date
PensionerFromDate = IIf(IsNull(Me.txtPDPensionerFromDate) = True, ????, Me.txtPDPensionerFromDate)
(instead of ???? i tried everything .. dbNull, vbEmpty, vbNull,sqldatenull, and somtimes it works but int the table stores "12/301899")
Integer
Dim CompanyID as integer
CompanyID = IIf(Me.cboCompany.Column(0) = 0, ????? , Me.cboCompany.Column(0))
I tried here instead of ????, tu insert "", ",," , " " , Cint("") itd. itd. . but nothing works.
Has anybody any idea ?
100 x thanks in advance
Forms :: Making Data In A Field On A Form Appear If Content Is Not Null
Dec 31, 2014I have a subform with continuous records. One of the fields in the recordset of the subform is a field named "Remarks". This field does not need to be visible on the continuous subform as it is rare that this field will have any entries.
I plan to apply conditional formatting on another field (IDcardNo) in the record line of the continuous subform so that when field "Remarks" contains any data it will show as a different format on the field IDcardNo.
I would like to make a small form appear when one points to the IDcardNo field with the different format, so that the data in the field "Remarks" pops up when one points to the field IDcardNo with altered format, showing that there is data in the field "Remarks".

Salutation = Me.Salutation

This code is working fine, until it hits an empty field, and then I get an error message: Run time error '94':
Invalid use of NullIs there some code I can use to tell it to skip any null fields?
Queries :: Join Results Of Unmatched Query With Matched Query To Include Null
Mar 24, 2013I am trying to do the good 'ol sales report (query) to include customers with no sales.
I have a customers table, account number table, sales table & sales (line) detail table. (all linked in that order)
If I run a query to show customers (in the customer table) with account numbers, that works
An unmatched query to show customer without an account number works (but of course the unmatched account number field isn't shown).
How can I get the two two be shown together with the "unmatched" having a null or 0 for their account number?
I am guessing in principle, the resulting solution can be modified to show customers without sales alongside those with sales?
