I'm really not sure how to go about this. I'm creating a course booking system and when creating a booking I need to check for current bookings with the same employee and course id's (i.e. the employee is already booked on the course). The query takes the employee and course id's from a form, and is initialised when the 'book' button is pressed. It correctly selects if the person is already booked on the course but I want the query to return a value to the form i.e. if it returns null/false then the booking can be created but if it returns a record/true then the booking already exists and a message box can be displayed.
I'm not sure if I'm going about this the right way, can anyone suggest how this can be done as described above or suggest a better way of doing the task?
Is it possible to filter a forms records by using a boolean True/False field. I want to show all current records for option 1, Expired records for option 2, and all records for option 3. The form is based on 'tblMembers' which has a field [Expired] which is a boolean yes/no field formatted to true/false.
I have a query that shows banned users (I work in a school). When a student's ban has ended, a tick box is checked in a form linked to tblBannedUsers to show they are no longer banned.
The query itself simply queries all records in tblBannedUsers with a username field (UserID) taking search criteria from a box on a form.
However, I want to filter out the students that are no longer banned (those with a tick in the checkbox). To do this, I thought it would be a simple case of editing the query, and in the Ban Lifted field criteria, use =False to say I only want those records with a tick.
This doesn't work and I still get all records given the combo box filter (which are just filtering for a username...if I leave it blank it gives all records via Is Null).
What should I be putting in the criteria to filter out those records with a ticked checkbox?
Thanks,
Steve Swallow
EDIT: I've just done a test query and <B>No</B> is the criteria to use, but when I use this criteria in my query which also take data from a form's combo box it ignore the <B>No</No> criteria.
I'm trying to limit the records on a subform via an option group selection. The group has 2 options: optionTrue (option value = 1) and optionFalse (optio value = 2). I have the following code in my query criteria of the true/false field.
IIf([Forms]![FrmHome]![frameProcessed]=1,-1,0)
The false part works, but the true part doesn't. I've tried many variations using true/false, using checkboxes, etc. and nothing works.
The database is SQL Server if that matters.
Any suggestions?
Also, is their a way to have an option for True or False or ALL?
There are around 100,000 records to update. Would a SQL Statement be more efficient?
It is a local table being used to sum up the results of a handful of rules. The columns can only hold True or False (datatype) If and only if all columns are True - then true
MyRow T T T T T T T T T T - Sum in next column is T MyRow T T T T T T F T T T - Sum in next column is F
Speed is very important. The Recordset for a single row is still open on the Currrent Record since the Update just finished.
Code: RS_RE_1SegStatusProfiled.Fields("Total") = (RS_RE_1SegStatusProfiled.Fields("RE_1") AND CStr(RS_RE_1SegStatusProfiled.Fields("RE_2") AND (RS_RE_1SegStatusProfiled.Fields("RE_3") ' and so on
My guess is that since the recordset is open to the current record on a local table, it will be efficient to just re-read all of the values and And them together.
Since I have code writing to each record, I could also go through all the extra assignment of a local variable.
I have a form that shows the records found in a query if the completed tick box is false. this is fine, but i have also put the tick box on the form, and wish the user to tick it when they are done how ever they, get a beeping error and wont let you change it to true. Can anyone suggest the resolutoin for this.
I want to create an opion group with two rad buttons in it. The values of those button wont be values but as true or false in order to use it in another text box to performa calculations. EX.
=IIf([radNew],"Hello",IIf([radUsed],IIf([txtAgeofCar]<184,[txtExciseinTotal]=Null,IIf([txtAgeofCar] Between 185 And 365,[txtExciseinTotal]*(-0.15),IIf([txtAgeofCar] Between 366 And 1095,[txtExciseinTotal]*(-0.2),IIf([txtAgeofCar] Between 1096 And 1825,[txtExciseinTotal]*(0),IIf([txtAgeofCar]>1825,[txtExciseinTotal]*(0.25))))))))
As you can see radNew and radUsed are the Options Buttons. Its not working in an option group.
My client has an Access database where the value of a checkbox is stored in a field called Exclude_PropCount as -1 or 0. I am trying to get this form working online, but have been unable to successfully store this value in the db. I have set up a simple page to test it, and my relevant code is this:
sql_save = "INSERT INTO HVM_Data (VC, Exclude_PropCount) VALUES ('a9', '-1')"
con.Execute sql_save
set duplicateVC1 = db.Execute("SELECT Exclude_PropCount FROM HVM_Data WHERE VC = 'a9'")
response.write duplicateVC1("Exclude_PropCount")
But no matter whether I have '-1' or '0' in the INSERT statement, the response.write line always returns "False". And of course I've tried inserting "true" and "false", but it only accepts an integer.
As exceptionally bad timing would have it, my server is slightly fubar and I can't download the database to my PC to see what's actually being stored there, but looking at the above code, do you see anything I'm doing inherently *wrong*? This is my first time with checkboxes so I won't be surprised if that's the case. Hints?
Using DoCmd.TransferSpreadsheet I'm exporting a table which has a couple of Yes/No fields formatted as Yes/No. However when I export, they appear as TRUE/FALSE? Am I doing something wrong?
In a form, the value of any field may determine if the other field will be true or false. For example in my form, inventory, if value in code is equal to 2 then the Field Table will be automatically false.
I have a report where my customer wants to be able to input a value and then be able to select whether the report shows values above or below that value. I have a combo box that has 2 values (1=Less than or equal to, 2=greater than or equal to). There is a text box where he inputs the rate to compare against (e.g. $75). When he hits submit, the application stores the values of the combo box and text box into global variable and then I have a public function that can be used to retrieve the values. GetHRate() gets the value to compare against and GetHRateCompare() gets the value to indicate <=(1) or >=(2).
In my query for criteria for rate I have this expression: IIf(GetHRateCompare()=1,"'<=",">=") & GetHrate()
I've tried every combination of double quotes, single quotes, no quotes moving the GetHRate inside the IIf statement and nothing seems to work.
If I just hardcode <=GetHrate() into the criteria it works perfect but that does not achieve my goal of letting him select over/under at run time. Here's the full query:
SELECT qryCustomers_AverageTimeByScheduleID.ServiceName, qryCustomers_AverageTimeByScheduleID.ScheduleID, qryCustomers_AverageTimeByScheduleID.SumOfTotalTim e, qryCustomers_AverageTimeByScheduleID.PropertyID, qryCustomers_AverageTimeByScheduleID.PropertyName, qryCustomers_AverageTimeByScheduleID.MonthCount, qryCustomers_AverageTimeByScheduleID.AverageTime,
My first question is how do I append 00001 so I can have a value for the false side of 9123400001 instead of 912341...My second question is why does it prompt me to enter parameters? It also produces all false values from the if statement...What I am trying to do is use a column that has either a Y or a N and using the if statement to correspond with different formulas depending on the Y or N.This what I have so far.
IIF function not returning the false value. I have the following results based on the query shown below.
SELECT Trade.Ref_No, Trade.CERS_Price, Market.[USD/EUR_Rate], IIf("CERS_Price_currency = US Dollar.USD",[Trade].[CERS_Price]*[Market].[USD/EUR_Rate] , 0) AS [Price In Euro], Market.[USD/CHF_Rate], Trade.CERS_Price_Currency FROM Status INNER JOIN (Market INNER JOIN Trade ON Market.MarketDate = Trade.Trade_Date) ON Status.StatusID = Trade.StatusID;
Price In Euro USD/CHF_Rate CERS_Price_Currency CERS_Price 35 7 US Dollar. USD 5 91 7 Euro. EUR 13 1,715.00 7 Brazil Reais. BRL 245 759.00 33 Indian Rupees. INR 23.00
As you can see returns all calculations whether is USD or not. Can you help please? Ultimately I want to do this for all other currencies by nesting the IIF function.
In access report, I'm trying to change color of text in specific records based on the true/false value in another record. Works in forms using conditional formatting, but won't seem to work in a report.
Here's what works in forms : IIf([2009 Symposium]=true, forecolor=255 ....this changes the records to red.
But using the same expression in a report doesn't change the text color.
I have created my tables and form and am now trying to run reports to organize the data. I have figured out how to group the individuals by group and treatment, but can't figure out how exclude individuals from the final list if they are already in another. As background, some of the individuals are eventually excluded from the experiment, though I keep the initial data. When the exclude individual checkbox is checked ("True" on the report) I do not want the individual to be listed in the "False" list, even though there are entries for that individual when that checkbox wasn't checked (when it was "True"). This is so I can get an idea of the current totals in each group.
Implant Period >Treatment >>Exclude individual? >>>Individual ID
I feel like this should be a fairly simple task, but I cannot figure it out... Maybe there is coding to exclude individuals from the "False" list if they are already listed in the "True" list?
Greetings, I've been banging my head on this for days, and what really makes this difficult is the number of websites which say it should work just fine!
I'm working with Access 2003 and trying to make use of the IIf function. I have given my fields generic names in the examples below.
I have a number of items I want to search upon in my search form. Each item has a check box and a combo box. I want the query to look at the check box. If the box is checked, I want the query to use the value in the combo box. If the check box is UN checked, I want the query to ignore this field and return all values. I thought this was simple, until I tried to do it!
Here is my code, placed in the Field-name criteria box of the query:
This will return all records where Field-name = 2.
So... my original code should work! Because no "false" condition is stated, the query should be blank, and should return all records. But it doesn't! Truly maddening.
Here are some attempts which did not work:
IIf([Forms]![form-name]![checkbox-name]=True,[Forms]![form-name]![combobox-name],>0) ---> The ">0" caused an error. In fact, I can only specify an integer - all else, including things with operators, do not work.
Working with nulls - it does not seem to recognize an unchecked box as a null.
That's the short version of the story - any and all ideas welcome!
I have a table called Prem. It contains three fields (Offer, MailCode, MktgProgam). I want to have a form where a user can select. the Offer (from the offer field) Once selected, it takes the MailCode and MktgProgam information from the Prem table and uses that info (MailCode, MktgProgram) to pull from the main table called "Cust" Is this doable?
I am using Access 2007. Second, I am using two tables, Inventory and Service Request. Inventory is a list all the Inventory, with has things like location (building & room number), type (desktop, laptop, etc.) and access tag number. Service Request also has Access Tag Number (should link back to Inventory) & date of reported/resolved problem and description of problem/solution.
On my form for Service Request, I have the access tag number as a fill text box, when you double click on that text box, it runs a Query that asks for the 1) Building, 2) Room Number & 3) Type . . . Query currently opens in a the spread sheet view that shows those three things but also the Access Tag Number associated to them.
I would like that Access Tag Number to just return into the field that was double click to start the query.
Hi I have a subform with several records entered. When a particular entry is made in the subform eg. chocolatebiscuit I want the subform to not allow any more entries - records in that particular subform Is there a easy way to do this?
I have tried to do this by saying Me.Form.allowadditions = false
Unfortunately this works on the whole form and stops the next subform - belonging to the next main record from adding a new record. How do I restrict the new records in A particular subform?
I tried Me.Form.allowadditions = true on entering the subform
but it doesnt work every time.
Also i put on enter if not chocolatebiscuit then allow entries but for new records it takes the last entry in the subform which could be two records back in the main form says yes there is a chocolatebiscuit and will not allow a new record.
This seems really straight forward to me. I have 3 forms - FormA, FormB and FormC. When I open FormA the user inputs some information, when they tab to the last field, FormB opens (which I want to be invisible) and Form C opens.
I've tried putting this coding on the Open event of FormB: Me.Visible = False
I've also tried putting this code on the Open event of FormC Forms!FormB.Visible= False
Neither work. My form (FormB) still displays when eithr event occurs.
