I have an access table with the following columns
Field Name Data Type
Sending_Division_$ - Currency
Receiving_Division_$ - Currency
Check_Total_$ - Currency
I need to have Check_Total_$ = 0 if the other 2 columns cancel each other out (one is negative and one is positive). I keep getting the
"Invalid SQL Syntax - cannot use multiple columns in a column-level
CHECK constraint.
I have searched the web and tried to use the validation Rule box with no avail.
=[Sending_Division_$]+[Receiving_Division_$]
Thanks for taking a look!
This will work for Access 2010+.
You will have to redesign the table (better from the start).
First of all the table needs a "Primary Key", say Id as AutoNumber.
Then add the first 2 columns so now you have 3 columns (with the ID).
Save the design of the table (without exiting) and now add the column Check_Total_$ and select Calculated under "Data Type".
In the "Expression Builder" build the expression you want as:
[Sending_Division_$]+[Receiving_Division_$]
Save the table.

I need some help with an Access expression. I keep getting a syntax error.
I'm trying to get a calculated field from the combination of another calculated field.
Note that the LaserCuttingRate field is also a Lookup field. So it's not a simple entry field. It becomes a selector of the 3 choices.
IIf([LaserCuttingRate]="200",([CuttingTime]*200/60),IIf([LaserCuttingRate]="400",([CuttingTime]*400/60),IIf([LaserCuttingRate]="100",([CuttingTime]*100/60)))
All help appreciated.

I think you're missing a final close bracket.
There are 6 open brackets ( but only 5 closing brackets )
UPDATE - second issue
Two extra issues
The checks on number either don't need, or shouldn't have double-quotation masks
The final IIF also needs a false clause at the end (in the example below, 0).
Try this - I have put it into an Access database scratch table and it worked. (If relevant, note that I had LaserCuttingRate and CuttingTime set as doubles, as well as the Result Type for the calculated column).
IIf([LaserCuttingRate]=200,([CuttingTime]*200/60),IIf([LaserCuttingRate]=400,([CuttingTime]*400/60),IIf([LaserCuttingRate]=100,([CuttingTime]*100/60),0)))
I have a table named "customers", and a table named "cases". These relate to real estate transactions. On the table "cases" I have a field for "other party", which lets you enter a new customer or pick from an existing one if we have already had that person in our database from a different transaction.
I have created a form with a listbox so I can search all the case records via the customer and other party fields (I also show some other info about the case but am not needing to search that info). In formview the listbox shows the customer name, but only shows the ID number for the other party. When I go to the rowsource, buildevent, and see the query in datasheet view, the records display the way I want them to -by name, not showing ID numbers.
Why won't it display correctly on the listbox??? Please help! I have spent way to many hours trying to figure this out :( This is my first time using access and I am just figuring it out as I go.
this is the SQL from the query in the listbox rowsource:
SELECT Query3.Customers.ID, Query3.[Last Name], Query3.[First Name], Query3.[Other Party], Query3.[Property Address], Query3.[Assigned To], Query3.Lawyer FROM Query3;
and this is the SQL from Query3:
PARAMETERS [ [forms]]![FRM_SearchMulti]![SrchText] Text ( 255 );
SELECT CasesALL.*
FROM CasesALL
WHERE (((CasesALL.[Last Name]) Like "*" & [forms]![FRM_SearchMulti]![SrchText] & "*")) OR (((CasesALL.[First Name]) Like "*" & [forms]![FRM_SearchMulti]![SrchText] & "*")) OR (((CasesALL.[Other Party]) Like "*" & [forms]![FRM_SearchMulti]![SrchText] & "*"));
Listboxes and combo boxes have a hidden column feature, usually a primary/foreign key of underlying table. Users generally do not know which primary key they should pick, hence the connecting name/item displays for their selection. Your situation sounds like the key is not being hidden but displaying and with two columns designated, you do not see the Other Party field.
To fix, under Property Sheet / Format Tab of the listbox, adjust Column Count and corresponding Column Widths according to your query (i.e., recordsource of listbox). As shown below the first column of query is hidden with 0 inches of display while the next two fields will display at 2 inches:
Column Count: 3
Column Widths: 0"; 2"; 2"
...
List Width: 4"
Be sure column widths add up to your List Width or there will be cut-offs. Also, inches are automatically added when you enter numbers. Finally, do note the data value of the listbox will be whatever is designated in Bound Column under Property Sheet / Data tab:
Bound Column: 1
Usually, the bound column is the hidden field or it wouldn't be hidden or used!
You probably miss to set columnwidth(s) of the listbox to: 0
I am trying to build a query which will look at the data in two fields in two different tables and check to see if the data is the same, if it is I want it to return the number of times it is matched, if it isn't I simply want it to return the text saying "No viewings".
I have constructed this query in my access database which has the field from the first table "Property" and the second field I want it to compare the data with, "Viewings". I have build the following expression using the build tool, however I am stuck to make it work since every time I get this error message when trying to run the query: "Your query does not include the specified expression 'Property Viewed' as part of an aggregate function."
totalViewings: IIf([Viewings]![Property Viewed]=[Property]![ID],Count([Viewings]![Property Viewed]=[Property]![ID]),"No Viewings")
Any help how to overcome this error would be very appreciated.
Thanks
I would suggest doing something like this:
1) Assuming this is something you are developing yourself, make sure your data structure is all in order first. Since I dislike relatively code-hostile identifiers, I'd have the tables as so -
Properties - PropertyID (AutoNumber, primary key), HouseNumberOrName, Street, etc.
Viewings - ViewingID (AutoNumber, primary key), PropertyID (Number/Long Integer), ViewingDate, etc.
In the Relationships view, Properties.PropertyID would then be set up to point to Viewings.PropertyID in a one-to-many relation.
2) Your actual query I would then break into two, the first to compile the data and the second to format it for display. The first would go like this, saved as ViewingCounts...
SELECT Properties.PropertyID, Count(Viewings.PropertyID) As ViewingCount
FROM Properties LEFT JOIN Viewings ON Properties.PropertyID = Viewings.PropertyID
GROUP BY Properties.PropertyID;
... and the second like this, saved as ViewingCountsForDisplay:
SELECT Properties.*, IIf(ViewingCount = 0, 'No viewings', ViewingCount) AS Viewings
FROM Properties INNER JOIN ViewingCounts ON Properties.PropertyID = ViewingCounts.PropertyID
ORDER BY Properties.PropertyID;
I'm trying to follow Microsoft's example on how to add an "All" option to a ComboBox in Microsoft Access, but their article does not do an adequate job of providing guidance, aside from specifying the code.
What I'm trying to do is build a form that allows a user to select an option from a ComboBox (the options are generated from records in a table), and then build a report filtered based on the user's selected option. The ComboBox consists of 2 columns: the primary key/ID of the records and their displayable names.
I can't understand the VBA code Microsoft provides enough to figure out what is going on, but I would like the "All" option in my ComboBox to either have a blank primary key/ID, or one that = 0. That isn't the case, as selecting the "All" option when using the form results in the error message "The value you entered isn't valid for this field". This leads me to believe that the "All" text is getting filled into the primary key/ID column instead of the display column. The example instructs me to assign the display column number as the "Tag" property of the ComboBox - and in this case, my display column number is 2. However, this (and pretty much any other value I add) results in the aforementioned error message.
Any idea if Microsoft's example is even applicable to my case, or do I need to adjust their code somehow?
Check the Control Source property of your combo box. Sounds like it may be bound to a field in the form's record source. If you make it an unbound control (nothing in the Control Source property) you should be able to select any item from the combo's Row Source without Access complaining at you.
Say your combo's Row Source is a query like this:
SELECT id, disp_name
FROM YourTable
ORDER BY disp_name;
You can add an "all" row with a UNION query:
SELECT id, disp_name
FROM YourTable
UNION ALL
SELECT TOP 1 0, "**ALL**"
FROM AnyTable
ORDER BY disp_name;
AnyTable can be just that. If you happen to have a table which contains only a single row, use that one ... and you wouldn't even need the TOP 1 part. Just try not to use some ReallyBigTable as AnyTable.
Edit: Actually some ReallyBigTable would be fine if it has a primary key or other unique field which you can use in a WHERE clause to retrieve a single row:
SELECT id, disp_name
FROM YourTable
UNION ALL
SELECT 0, "**ALL**"
FROM ReallyBigTable
WHERE pk_field = 1
ORDER BY disp_name;
UNION ALL will return all combined rows. If you have any duplicate rows, you can thin them out by using just UNION instead of UNION ALL.
How do I bind a text box with a field, which doesn't belong to form's "Record Source" table, through the Design View?
Example: I have "Order.cust_id" (Record Source=Order) and I want to display "Customers.name". I believe it is trivial but I have no experience with MS Access. I tried to use the text box "Control Source" property but no luck.
One method would be to convert the text box to a combo box. Then set the row source to include both the cust_Id and the Customer.Name from the customer table. SQL statement example
Select Cust_ID, Name From Customer
Order By Name;
By setting the number of columns to 2 and the column widths; the first column as zero (i.e. "0;6") then the foreign key would be hidden from the user and the customer name would be displayed.
Note this method does force you to have limit to list set to true.
Also you do end up with a drop down list which may not be what you want.
You can use DlookUp as the control source of a textbox:
=DlookUp("[Name]", "Customer", "ID=" & Cust_ID)
Syntax: What to look up, table name, where statement
The Where statement should follow the rules for Jet SQL, which means that you must use delimiters if the field is text or date format.
Note that Name is a very bad name indeed for anything. I suggest you rename the field immediately before things get worse.
It can be useful to know the error(s).
You could create a new View (e.g. OrdersAndCustomerNames), select all the columns you want to use in the form, then instead of using the Order table as Record Source, you would just switch to OrdersAndCustomerNames. You say you have no experience with MS Access, so I am guessing you are not building anything huge and overly complicated, so I would do it this way. I am quite sure it can be done more elegantly but this will do for now.
