Table / Relationship Problems - Aargh!
Nov 7, 2005Hi
I'm having real problems with this and just can't seem to get it right. Hopefully someone will be able to point me in the right direction.
The system that I'm trying to create is very similar to a standard order system, the only difference is that it is a quotation system. It consists of quotes and products instead of orders and products.
My problem is with the following. A product is categorised as a category of product. Hence, I have a categories table. Different quotes have applicable categories, so only products belonging to those categories can be included for that particular quote.
My problem is that I do not seem to be able to prevent any product being selected for any particular quote. I always end up getting the whole lot.
My larger problem is that I don't think that I've clarified the relationships properly. I don't know if I need an intermediate "appropriate categories" table and then an "eligible products" table. I also don't know if the fact that my products are not being filtered is down to my poor design or whether I should be enforcing the appropriate products through some cunning SQL.
I am really at my wits end as nothing I do seems to work.
If you have any ideas at all, please, please HELP ME!!!!
Thanks :eek:
Modules & VBA :: Creating A Function That Counts Records And Use That Function In A Query
Dec 11, 2013So basically I need making a function that will count the number of records from another table/query based on a field from the current query.
View 2 Replies View RelatedForms :: SUM Function Produces Error From Calculated Function
Jan 30, 2014I have a project at hand and it's been a predecessor of mine and client has asked me to do some work on it and extend functionality - but I have not really delved into Access before and I have had to worked my way through to this final snag :/
The Main Form has one sub form. This sub form allows the user to add multiple order items i.e. qty, stock, description from records within the system - fairly straight forward.At the last column of each row is the sub total of those particular items i.e.
Qty Unit | Item ID | Total
-----------------------
2 | 1234 | 80.00
------------------------
1 | 43526 | 20.00
------------------------
> | |
So the total is a function of =[Qty Unit] * [Unit Price].Then in the Footer of this SubForm is the Sub Total
=SUM([Qty Unit] * [Unit Price])
All fine and well..... However, the additional functionality kicks in.
Lets add the additional customer_id from the Main Form. Each Item bought is dependent on the customer_id i.e. they get special prices depending on who they are.So a New table is made which has the Item ID and SpecialPriceID (of a table to define as a specialPrice) and the Price linked to this Item and Special Price category. So say that there are two groups of users "wholesale" and "nonwholesale" these would be SP_1 and SP_2 and each client is defined either one of these, and each stock item has a Price for each SP_1 and SP_2. Hopefully I've explained myself there.
Back to the SubForm. So now the Total needs to calculated differently with needed the external customer_id from the Main Form.
Code:
Function CalculateSpecialPrice(ItemID As String, CustomerID As String, Unit As Integer)
Dim SPSelect As String
SPSelect = "SELECT Price FROM [Items_SpecialPrices] WHERE"
SPSelect = SPSelect & " ItemID = '" & ItemID
SPSelect = SPSelect & "' AND SpecialPriceID = (SELECT SpecialPriceID FROM Customers WHERE customer_id = " & CustomerID & ") "
[code]....
its the sub total I just keep on getting #Error on. I have even watched (using alerts) that the correct return variable is the same as the individual rows. This is the equation I used for the SubTotal within the footer.
=SUM(CalculateSpecialPrice([Item ID], [Form]![FormName]![CustomerID], [Qty Unit]))
#Error
Date Function/need Time Function

Now Function To Convert To Date Function
May 25, 2006Hi all,
I need a little help. In my DB, I have a command button set up (I was tired of typing in dates) for date, but I used the Now function, which also gives me the time.
Now I have over 3000 subrecords of the main ones. I now need to queries transaction for that specific date, but it also retrieves the time.
I tried to go back and change the NOW to DATE in VB, but the code does not run.
How do I change all records that have date and time (using NOW function) and only click that command button to show only the date (mm/dd/yyyy)?
Thanks in advance.
Function
Aug 1, 2005Is there any function that can convert either a True, False, "Yes", "No" or Null value.... to a yes/no (check box) data type?
What I want to do is create a make table query. I would like to add a checkbox field from the query. So if there was a function that could convert a data type to a Yes/No checkbox, this would be very helpful...
To give you and idea of what I'm talking about...and how I want to use this... If I am making a table from a query and I want to add a number field, but leave it empty for the time being, what I can do is make a new field in the query maybe call it "Number1". What I would do is Add this as a field in my make table query:
Number1: Cint("")
This will add a blank field that is formatted as a number field when I run the make table query.
So using the same logic, I'd like to make a blank (or unchecked) Yes/No check box field when I run my make table query.
Anyway...that's what I'm hoping for.... I hope someone can help!

Function Isn't Available
Nov 3, 2005I'm having a problem getting a form to open. I'm using access 97 on on XP machine and whan I open my database I get Function isn't available in expressions in query expression '[Case Types]![theName]&"-"&Format([SourceDocs]![CaseNumber]&"","00")&"-"&Format([SourceDocs]![CaseYear]&"","00")'.
This database works fine on a Windows 2000 machine running Access 97 but none of the XP machines will open it.
Any suggestions?
Thanks,
Rick
CHR() Function Not Available
Nov 10, 2006I have a database in which I am designing a report which includes a name/address block. I am surprised to find that the report does not recognise the Chr() function in the text box control source string "=[Organisation] & Chr(13) & Chr(10) & [Address]..."; designed to insert a CRLF between the contents of the named fields.
I know the syntax is correct because I've checked by using the expression builder to replicate the code. (Expression builder includes the Chr() function, as expected.)
The interesting thing is that the function is recognised in other databases used on the same machine, both those created remotely and locally.
Anyone know what could be going wrong?

Function Is Not Available
Sep 4, 2005I am using a crosstab query to gather info from a table. I am using the Format [DateAppt], "mmm". The query ran successfully before but I now get the error "Function is not abailable in expression in query expression 'Format ([DateAppt], "mmm")'. This is used for column headings in a report that gives results by month.
I am using Microsft Office 2000 Premium with XP Professional operating system.
I used the original disk to repair Office thinking that the function was missing from the function library but to no avail.
Does anyone know how to restore this function?
Thank you,
Jack
Help With IIF Function
Sep 29, 2005Just wonder if anyone could give me some help on an IIF function used in my query:
I have a table which has numerous “W” codes, the charging for an order does not occur if it has a W12 or a W14 code and has no “[Authorising Name]” BUT does however charge if the weight of the order is over 100kg
IIf([WCode]="W12" Or [WCode]="W14",IIf([Authorising Name]="",0,[charge], IFF ([weight]>99,[charge],0)))
I can get this working for a single W code but not for the 2 OR I can get it working for both Codes but then the weight side doesn’t.
I have tried all combinations of <> = < etc etc but still no luck., I think I need another OR but no matter where I put it I hit problems either with the function or the result.
Another small issue, my [authorising Name] field can appear to be empty, but in the field are spaces what is the best way for ensuring I capture both empty and theses space records ?
Thanks in advance

Using Max Function In SQL
May 4, 2006I have parts table in Access where a part id is automatically assigned to each part number. I am trying to get the last part number entered in the parts table by querying on the max part id. The max part id will always be the last part number entered in the table. I don’t want to display the part id though; I only want to display the part number associated with that max part id. This is what I have been playing with.
"select part_no, (max)part_id as part from tblPartsSignOut "
Can someone give me some insight on how to structure this query the correct way?
Thanks

Help With Max Function!
Jun 28, 2007I'm trying to link a table to a query called M Gate Status. Each product has a certain status that matches it and I'd like my query to show the most recent status for each product. I've created an M Gate Status # column on the MGS table and want to select the maximum number, but I can't figure out the max function to put in my query. I'd like to do this without using VBA.
Thanks in advance!
IIF Function
Jul 3, 2007Hello everyone,
I need help modifying my query:
SELECT DISTINCT EqInitial, EqNr, LastEventDt, DateDiff("d", StartDt, Date() ) AS TotalDays
FROM EQUIPMENT;
The table Equipment is populated with data that comes from a third party so I cannot change it. Sometimes the StartDt field of this table has no data and when executing the query above the DateDiff function will obviously not return anything for the TotalDays field of that particular record.
I need to populate the TotalDays field with 1 everytime the StartDt fields has no data.
I though about using the IIF function, but I’m not sure if this is the best approach and I don’t know the syntax to “make” the TotalDays field show 1. :confused:
Your help is greatly appreciated .
Where To Put IIF Function
Jul 31, 2007Does an IIF function go in the criteria row?
I want to say if place1 has a 'U' in it put it into column 'Stuent1U' but if it has a 'C' in it, I want it to go into Column 'Student1C'.
Thanks to anyone who may help me.
IIF Function
Aug 11, 2007I am having a bit of trouble with some SQL now that looks like the following....SELECT [fields]
FROM [table]
WHERE ([field]=[control1])
AND (IIf([control2] Is Null,"[set value]","[>=control2 value]"));Can someone tell me where I have gone wrong??
The idea is to get a range of values with the "IIF" function (>=control value) if a value is manually entered into the control and a set value from the query if the control is left blank.
Right Function
Aug 17, 2007In my query I have a field that contains an id. The id consists of 8 characters. I need all part to find all parts where the last character in the string is an "F". This is how I have the query setup right now.
Field: Finished Good:Right([Part]![User_8],1)
Criteria: "F"
When I run the query I get an error - ODBC call failed. ORA-00936:missing expression (#936).
Why am i getting this error?
