I want an example of choose function to write in expression builder in access 2007 ..
I have a size as 1/4,2/3,4/9 etc to be converted to ABC,DEF,GHI etc . i have nearly 40 entries so i think choose statement would do it .. moreover i cant find switch statement in expression builder .......
For example one could be to replace the text ..... or any other method to change the size to alphabetical grade.
I need to clean up data from text file which is huge.
I wonder if Access Expression Builder can mirroring "IF function" from Excel Here is what i am trying to do The data consist of multiple customer and multiple date. But the layout only specified customer ID once eg.
CustID: aaaa
Date
01012013
02012013
03012013
CustID: bbbb
01012013
02012013
When exported the file I used Fixed Width command to separate Date Column and Cust ID column.
Below is the result that I am looking for
CustID: aaaa : aaaa
Date : aaaa
01012013 : aaaa
02012013 : aaaa
03012013 : aaaa
CustID: bbbb : bbbb
01012013 : bbbb
02012013 : bbbb
1. Column A is Date
2. Column B is Customer ID
because Customer ID in column B only appear once, I need to create another column to populate that Customer ID whenever the transaction related with that Customer
3. Column C is the column where i tried to populate Customer ID to each date related to that Customer.
If I worked in excel the formula will be --> IF(AND(C5="",B6=""),"",IF(AND(C5="",B6<>""),B6,IF( B6<>"",B6,C5)))but in access i am stucked.
I have this following problem:
I want to program a textbox. In the expression builder of the properties sheet's control source I've programmed this following code:
=IIf([word1] Or [word2]=1,1,0)
It works. But I have to add 37 other "words" and I can not.
I tried:
=IIf([word1] Or [word2]=1,1,0) or =IIf([word3] Or [word4]=1,1,0) Or....
But it doesn't work.
In Expression Builder, I have the query(in the Criteria row) set to run based on values in different fields on a form. When one of the fields is empty however, the query will not return any records.
How can tell Access to ignore the fields when those fields on the form are empty and only look at fields that are not null.
I want to count the number of occurences in a datatable when loading a form. BUT i want only to count if it is equal to a value on a text box on this same form.
what i made:
1-created a unbound textbox
2-inserted on "control Source" this expression =DCount("*";"T_Pendentes";"[disponente.Procurement]= " & [me].[disponenteProcurement].[Value] & "")
where * is to count all, T_Pendentes is the table, and de expression is the criteria.
Good day all
Heres what im trying to do:
in one textfield i have =Count(*)
this returns all the records in my db.
now i want to split it up. i want to count all the records for each month.
my field name is datein_now but its just a normal textfield and not a date field.
example in field: 05/02/02 10:24:31 AM.
also got a datein textfield:05/02/02
i had
Count(*) where datein_now between 05/05/01 and 05/05/31
please help

I now try to rework on an old project but when I try to run some queries I get an error message: Undefined function 'Date' in expression . The same happen for the Format function.Both are built in Access functions
View 5 Replies View RelatedI'm relavtively new to databases but after a steep learning curve (being left with many databases created by my old manager with no instructions on use) I'm getting there.What I am trying to do is pull out the date from records in a field called "Model_ID". The Model_ID field contains this kind of information:
Endscopy20120726JSmith
GISurgery20120521JDoe
I want to bring back "20120726" or "20120521". In excel I can do this with the mid and find functions but find doesn't work in access. I've tried combining the mid function with instr function but it comes back as too complex!
When I enter a date into the [Return Text Date] field on my table and then select a value from the [Upgrade Fee] combo box followed by a selection from the [Upgrade Investment Class] combo box i want the value (or Date) in my Eligibility Date field to be amended by the given amount.
I have an expression, listed below, that i want to repeat (copy + Paste would be good) and amend the values. I have entered 2 and that seems to be all it will allow. I want to have 30 possible permutations to the fields 0 - 300 (in 50 intervals) by 5 (1,2,3,4 & 5)
The Code works below but I cant have anymore code in the expression builder
IDEAS please people.......
=IIf([Upgrade Fee]=0 And [Upgrade Investment Class]=1,[Return Text Date]+180,IIf([Upgrade Fee]=0 And [Upgrade Investment Class]=2,[Return Text Date]+150,""))IIf([Upgrade Fee]=0 And [Upgrade Investment Class]=3,[Return Text Date]+120,IIf([Upgrade Fee]=0 And [Upgrade Investment Class]=4,[Return Text Date]+90,""))
Hi!
I need some help.
I want to create a formula (using expression builder or something else) who will separate the word id=276616652 lang=FR temp=80 in a new column (for each word)
Id=276616652&Lang=FR&Client=Diesel649&Temp=80
by the way, im using this in a log database
I've built a query against a form and included a calculation to give me the average sum which looks like this :
=Sum([data field])/31*12.5
This work fine however, what is the best way to overcome the different number of days in the month ie; 28, 30 and 31? I've looked at the Expression Builder but getting lost :rolleyes:
Regards
Richard

Hi,
I am fairly new to Microsoft Access and can't get to grips with the expression builder. I have several fields where I need to add validation rules and no matter what I try I can't seem to get it right. E.g I'm trying to set a validatio rule for only allowing locations into a certain field. Could someone please give me some help or point me in the direction of a good guide?
Hi, i am making a stock control program in Access. I have designed several tables, forms and queries etc. but have come stuck at the point where i want to create a button so when i click it, it automatically changes the stock level of all the products that are low in stock, to their "target stock level".
I am confused about how to do this. I tried making a button and going into the expression builder and putting:
=[Product Stock Level]=([Product Target Stock]-[Product Stock Level])+[Product Stock Level]
This would basically change the stock level to the target stock level. But when i press the button, nothing happens.
Any help on this matter is greatly appreciated.
Thanks alot.
Im looking for a guide to teach myself how to use the expression builder.
I know how to write constraints in SQL, so with a bit of luck it will be similar. :P
A list of every command you can use might be just as good as a tutorial.
Can anyone point me in the right direction?
Thanks.
Hi,
I am trying to write an expression in my query which, given a condition, it uses the following criteria:
"Carmarthenshire" Or "Ceredigion" Or "Neath Port Talbot" Or "Pembrokeshire" Or "Swansea"
So far I have come up with this:
IIf([Forms]![Main Menu]![cboRegion]="West Wales","Carmarthenshire" Or "Ceredigion" Or "Neath Port Talbot" Or "Pembrokeshire" Or "Swansea")
However the Query builder complains the expression is incorrect or too complex etc. etc...
If I simplify it to this:
IIf([Forms]![Main Menu]![cboRegion]="West Wales","Carmarthenshire")
it works fine but unfortunately this isn't what I need.
Any help much appreciated,
Matt.
Hi all,
Should you write an expression the criteria field in a query and use IIF, an interesting little bug appears that I have not managed to get around. Should you want the expression to return a range as the criteria (i.e. Between ... And ... ) it can't do it because IIF tries to evaluate the range before it passes the result back to the query. I need it to actually pass the Between And to the query to use as it's criteria. It can't do this, so it passes back a null and of course the query fails to produce any meaningful result.
I need to do this as I have two date text boxes in a form so that people can search through specific dates, but in the table these date fields can be blank. (Basically it's a Date Completed field, so if the job hasn't been completed, the date is left as Null) So i need users to be able to leave both text boxes blank so that the resulting query will display the Null values as well. If they leave one blank, it auto sets itself to the a minimum/maximum date. When both boxes are blank i need to return nothing so the criteria is effectively blank or = Is Null And Is Not Null to display all records.
Example of WIP
IIf(IsNull([Forms]![frmListImgChng]![txtDateComp1])=True And IsNull([Forms]![frmListImgChng]![txtDateComp2])=True,#15/01/2007#,IIf(IsNull([Forms]![frmListImgChng]![txtDateComp1])=True,Between #01/01/2007# And #01/04/2007#,IIf(IsNull([Forms]![frmListImgChng]![txtDateComp2])=True,Between [Forms]![frmListImgChng]![txtDateComp2] And #31/12/2030#,Between [Forms]![frmListImgChng]![txtDateComp1] And [Forms]![frmListImgChng]![txtDateComp2])))
The red bits of code are test values. The first one passes back to the query as it is not a range, the second does not as it is.
Cheers,
Matt
Basically i have a drop down that i want controlling the Criteria for each field in my query to have an advanced search. If i leave a field blank the query comes up with nothing so i tried this:IIf(IsNull([Forms]![Inventory Report Search]![Model]),Is Null,[Forms]![Inventory Report Search]![Model])this is not working. it is still returning the query blank. if i put valid critera in the dropdown it comes back Fine.how do i make is so if a field is blank it will return it as null or not even there.Note: also tried this;Forms]![Inventory Report Search]![Model] Or Forms]![Inventory Report Search]![Model] Is Nullworks, But comes back as too complex after a few searches and when i open the query there is a million or's in there. so that wont work.
View 3 Replies View RelatedNow I have been working for a few months with ACCESS but one thing that keeps giving me trouble and that is the "Expression Builder". I look at the Microsoft Help and it is not good in explaining this part of ACCESS. I have Access books and they are not good with explaining this aspect of Acess. Is there anyone with a good source to point me in the direction to learning the Expression Builder better then I know now?
View 1 Replies View RelatedThis seems so simple and it probably is, I've probably been staring at my database for too long doing too many other things but here goes:
I want to create thank you letters for a list of people. I've made my query and gotten all their info together but now I can't make a report for the letter. I can make my text box but after that nothing seems to work out right. I'm not that good with VB code so I have been using Expression Builder which follows logic statements and not real code. I can't get even the address showing in one text box with 3 lines. Once I get that far I can get the remainder of my letter created because its all the same thing but I really need some help to get beyone the address!
Thanks
I need to implement the following logic in a report column:
IF hist_mis_cds!typgess = "", then calculated field= ""
ELSE
IF hist_mis_cds!typgess <> hist_code_translation! src_code_desc
then calculated field= "X"
ELSE calculated field= ""
I have implemented the following query in Expression Builder for the calculated field:
=IIf(HIST_MIS_CDS!TYPGESS="","",IIf(HIST_MIS_CDS!T YPGESS<>HIST_CODE_TRANSLATION!SRC_CODE_DESC,"X","" ))
When I click on Form View, I get "#Name?" in the calculated field.
Any ideas? Thanks.

Hi, I need some help using functions in queries. I can calculate simple arithmetic in calculated fields, but fail when using functions. For example I have attached a doc file showing a query. One table displays record ids, the other four have data for consecutive dates for each record. I cannot make the query calculate the standard deviation of the data for each record. What expression would I use, I know it is stdevp but when i try and create the expression i get error messages galore.
thanks
Hi, can anyone help me? I'm using an access database to collect information and pull reports. One of the fields in one of the tables contains dates and time. In my query I would like to be able to state that records created after 17:00 and before 08:00 of the next day, get counted in next day reports. (i.e. Record 1 created 26.05.05 at 18:01 would show in my report as coming in on 27.05.05 at 08:00 am). Thanks,
View 5 Replies View RelatedHi all!
I need to write an expession in the Expression Builder but I cant seem to get it correct. Here is what I want to do:
I have 2 forms and 1 query.
I want the criteria for my query to take the data from the loaded form, ie if form1 is loaded then take the value in field1/form1 as criteria, otherwise, if form2 is loaded then take the value in field2/form2 as criteria.
Form1 and form2 are never loaded at the same time.
Can someone give me a suggestion? Thanx for your help
I have query that filters my list in Access. The list can be filtered in different ways(like using a combobox). This is the criteria of the query for the field Title of the table Book:
Code:
Like IIf([Forms]![frmName]![cmbSearch].[OnClick];"*" & [Forms]![frmName]![txtSearchBar] & "*"; [Book]![Title])
What I want is when the cmbSearch is clicked, the list must show the Tiltes where the title of the book contains the words of the search bar. When its not clicked on that button, the list must show all the titles.
Here is the SQL of the query:
Code:
SELECT Book.ID, Book.Title FROM Book
WHERE (((Book.Title) Like IIf([Forms]![frmName]![cmbSearch].[OnClick],"*" & [Forms]![frmName]![txtSearchBar] & "*", [Book]![Title]))
The problem is the list filters whether I click on a different cmdButton or an optionButton. I dont know why [cmbSearch].[OnClick] doesnt work.
