I'm trying to do a calculation to refer back to a field if another field Yes and I keep getting the #Type! error.
The fields are [Written] which contains a currency total, [LR Test] which is the Yes or No field and [Written totals]. So basically what I want my expression to do is IF LR Test = Yes I want [Written Totals] to show the amount from the [Written] field, IF it's a No, then it could be Null or 0.
This is the calculation I have tried that returns with #Type!
IIf(([LR Test]=Yes),[Written],Null)
Any help or advice is greatly appreciated. I'm very new to access so it has been quite a struggle.
If your [LR Test] field is of the type "Yes/No", you can refer to it with True False.
IIf([LR Test]=True,[Written],Null)
This would also work, since Access stores a true value as a -1 under the covers
IIf([LR Test]=-1,[Written],Null)
Yes/No fields in MS Access are actually Boolean fields, as already mentioned by Josh in his answer.
So because [LR Test] is a boolean value by itself, you don't need to compare it to anything to get Iif to work.
This is enough:
IIf(([LR Test]),[Written],Null)

I would like to know how to get computed field in MS Access that shows maximum of a number or zero. I mean the function that is similar to the one in Excel Max(A1,0). How do I get this in Access expression builder?
I suppose the only problem you could face, is that if the field has a null value. To be safe, wrap the field with the Nz() function which replaces null to the given argument.
Max(Nz([YourFieldName],0))
When the field is numeric, the zero can be omitted.
Max(Nz([YourFieldName]))
SELECT IIf(YourField > 0, YourField, 0)
FROM YourTable;
This is what I had done, but i thought there was another way
Thank you very much for your quick responses
I have a table containing the following: Five Y/N fields and a calculated field [Priority Results] that totals the number of 'Yeses' from those five y/n fields. I'm trying to create another calculated field that will return a value of Low, Medium or High dependent on the number of boxes that have been checked. [Priority Results] currently returns the values 0 through -5. Low = 0 & -1, Medium = -2, High = -3 or lower. I've tried SEVERAL different versions of If/Then, If/Else, Iif statements and always receive a syntax error. I've read a lot of different sites and the following expression seems to be the most commonly used, but I'm still getting the error. Anyone have any ideas? I've even tried this statement on a non-calculated field and can't get it to work.
IIf([Priority results]<="-1","Low",IIf([Priority results]="-2","Medium",IIf([Priority results]>="-3","High")))
Here are the calculated field [Priority results] properties.
Expression:
[Class Non-Attendance]+[Instructor Referral]+[Late Registration]+[Low Starting GPA]+[Talon Log-in]
Result Type: Long Integer
enter image description here
The part of the table this question relates to has the following fields:
Class Non-Attendance: Yes/No
Instructor Referral: Yes/No
Late Registration: Yes/No
Low Starting GPA: Yes/No
Talon Log-In: Yes/No
Priority Results: Calculated field counting the Yes/No fields above
Priority Outcome: Calculated field (that isn't working) prioritizing based on Priority Results
Don't put parameters for number fields in quotes.
Consider:
IIf(Abs([Priority Results])<=1, "Low", IIf(Abs([Priority Results])=2, "Medium", "High"))
In a query or textbox, expression could be:
Switch(Abs([Priority Results])<=1, "Low", Abs([Priority Results])=2, "Medium", True, "High")
Parts of the question still confuse me, which is why this answer will be brief. You have a calculated field PriorityOutcome based on another calculated field PriorityResults and that is the problem. Access doesn't calculate PriorityResults before calculating PriorityOutcome. Instead Access says PriorityResults doesn't exist yet and passes null to PriorityOutcome resulting in either an error or a silent fail.
There are several fixes you can mix and match. You can repeat the calculation for PriorityResults inside PriorityOutcome: wasteful but often the fastest solution. You can also add a code module with public functions to do part or all of the calculations. Then refer to those public functions in your calculated fields Access intellisense can find public functions.
As the subject expresses, I'm trying to sum the values of a string field where spaces may exist. It must be done this way, unfortunately.
The database is very old. The original developer chose to make all fields Text fields; to get over the null value problems, a function was written in VB6 to replace any null value with a space. This cannot be changed.
Fast forward to now, I'm trying to create a report that sums the length field without changing spaces to nulls first, and it should be done entirely through the control source property of the report.
I've added some of what I've tried below, but every time the report is run, I receive:
Data Type Mismatch
...and I'm not sure how to get around it.
Ideally, I'd like to keep the users out of the database completely, and just add a combo box that lists the reports created in the database so they can be opened by name without having to run any additional update queries first.
=Sum(IIf([MY_LEN]<>" ",DCount("[MY_LEN]","MY_TABLE"),0))
=Sum(Nz(Iif(Trim([MY_LEN])='',Null,[MY_LEN]),0))
=DSum("[MY_LEN]","[MY_TABLE]","[MY_LEN]<>' '")
=Sum(Iif(Val([MY_LEN])>0,[MY_LEN],0))
=(SELECT Sum([MY_LEN]) AS MyLen FROM MY_TABLE WHERE (((MY_TABLE.[MY_LEN])<>' ')))
Is this possible?
Can't compare anything to Null. Can't say If x = Null Then because Null is undefined. So you can't test if undefined = undefined. Use If IsNull(x) Then in VBA and Is Null in query criteria. Don't really need IIf() for Sum() aggregate, other aggregates such as Count or Avg would.
To handle possible space, empty string, or Null for a text field holding numeric data.
=Sum(Val([MY_LEN] & ""))
I am facing very simple issue but not getting solution over it.
I have textbox in my ssrs report, I am passing value "1;prashant" or null to it. Now, if I pass value "1;prashant" to textbox then textbox should show only "prashant" and If I am passing nothing then it should be blank.
I have tried following IIF condition:
=IIF(IsNothing(FieldS!WIAPPORVER.Value),"",Split(Fields!WIAPPORVER.Value,"#")(1).ToString())
But, I above code is giving an error ["#error" shows in textbox] if I am passing blank value.
Please let me know, where I am wrong in this.
Thanks
There are probably better ways of doing this, but this is what my head came up with at the time:
=IIF(
IsNothing(Fields!WIAPPROVER.Value)
,""
,Right(Fields!WIAPPROVER.Value,Len(Fields!WIAPPROVER.Value) -InStr(Fields!WIAPPROVER.Value,";"))
)
I believe SSRS is trying to compute everything in the report at runtime, so in your case it is still trying to fetch index 1 from an array even though there is nothing in it and it crashes.
Edit: Changed parameters to Fields. I created a parameter to remake the issue at my side.
Just get the split out of the iif. Then in your iif, if field is nothing create a string that when split will return ""
=Split(IIF(IsNothing(FieldS!WIAPPORVER.Value),"#", Fields!WIAPPORVER.Value),"#")(1)
You are relying on the IIf expression short circuiting, but SSRS IIf expressions do not short circuit - the expression will try and work out Split(Fields!WIAPPORVER.Value,"#")(1).ToString() for all rows and fail when this value doesn't exist.
You can get this going by using text expressions, which don't get this error.
With test data:
And a simple table:
I have added columns with both your existing expression and a new expression:
=Right(Fields!WIAPPORVER.Value, Len(Fields!WIAPPORVER.Value) - InStr(Fields!WIAPPORVER.Value, "#"))
This new expression works for NULL values, empty strings and strings with no delimiter present:
My situation/problem:
TableA
id, postalcode, region
Criteria for the field i want to add value in (postalcode):
=IIf([tableA.Region]="Chicago","60064",[postalcode])
What i need to accomplish is an iif-query where:
In the field postalcode I check in the criteria if the field region equals Chicago. If so fill up the field with postalcode 60064 if not DO NOTHING
For the do nothing part I'm using the fields name, this is wrong?
am i using the criteria in the right field (the field i want to add?)
I'm using a selection query?
As you can see i'm a noob in access queries...
Can somebody give me the right iff statement?
Thx in advance,
D
I'll suggest you bracket table.Region differently, or eliminate the brackets there entirely.
=IIf([tableA].[Region]="Chicago","60064",[postalcode])
=IIf(tableA.Region="Chicago","60064",[postalcode])
If that doesn't fix the problem you're trying to solve, tell us more about the problem. If you're getting an error message, tell us what it says.
Taking a wild guess, that code as a field expression in a query will not give you an editable column in the query result set. If you want to pre-load a column value based on your criteria, but then allow the user to change the value, use a form. In the form's On Current event, load the value as you wish.
This is a dead old post but I think this was what you wanted:
=Like IIf([tableA.Region]="Chicago","60064",'*')
As far as I can understand,
if not DO NOTHING
You need to return nothing if the condition is false.
What you need is the WHERE clause instead of IIF
If I'm understanding your question correctly, you want a NULL value in Postal Code if it's not Chicago?
=IIf([tableA].[Region]="Chicago","60064","")
Please add another IIF query as OR
