I am relatively new to MS Access-2019.
I'm attempting to create a calculated field from an adjacent field. I receive the following error message when I write the argument in the calculated field:
Data Type Mismatch in the Criteria Expression
Online research and the use of library references tell me that I'm attempting to create a calculated field with data with different attributes.
However, a careful review of the "criteria in the expression" does not seem to support this error message.
Specifically, the expression in the calculated field is:
LateFee:[AmountPd]*0.02
As you can see this is not a complex expression.
What am I missing?

I am new to SSIS and trying to use the Derived Column Transformation, but after setting up the control flow I get this error:
I am loading the data from a View and I not sure why the Length and the Data Type columns aren't populated, any suggestion on the reason for error are helpful.
In SSIS, "DT_WSTR" cannot have a length greater than 4000.
Here, it tells you that it cannot determine the data type and length because the value exceed the expected range based on the matadata of the column you used.
To see the matedata of your colmns view, you can right click on the source activity and click on "Show advanced editor". In the popup click on "Input and output properties" and see the datatype of your columns:
If the length of the derived column can be greater than 4000, you have to use "DT_NTEXT" datatype.
One of the field in my data contains both numbers and text, which I usually import to Access via linked tables and setting this field type to number by default. However, the rows that contain texts will be imported as #Num!.
I am tying to convert the rows with #Num! to a default value using the function below. However, my query keeps showing #Num! for the rows with this error. Is there a way for Access to recognize #Num! errors? I have tried other functions like IsError but still unable to achieve the desired result.
IIf(IsNumeric([Field]),[Field],0)
This field type has to be in number because I have other queries that need to treat this field as number, hence I would prefer not to import this field as text.
Thanks in advance!
I have a form in MS Access that has an unbound control named boxReferenceMonthGtis that correctly displays a date.
This control Control Source property is =[GTIS_subform].[Form]![ReferenceMonth] which is a field of type Date/Time in a subform.
When I try to use this control in a query in the SELECT clause it shows this gibberish �䃤.
After reading this I added PARAMETERS [Forms]![Conciliacao]![boxReferenceMonthGtis] DateTime to my SQL, and the SELECT statement started showing the correct value.
However, If I try to use my control as a criteria to filter another field like:
WHERE DateSerial(Year([Departure]),Month([Departure]),1)=[Forms]![Conciliacao]![boxReferenceMonthGtis]
I'm prompted with
Data type mismatch in criteria expression.
What is weird is that if I filter the field [Departure] like:
WHERE ShippingTrack.Departure=[Forms]![Conciliacao]![boxReferenceMonthGtis]
There is no error!
What else I have tried without success
Same error (Data type mismatch)
WHERE CDate(DateSerial(Year([Departure]),Month([Departure]),1)=[Forms]![Conciliacao]![boxReferenceMonthGtis]
WHERE CDate(DateSerial(Year([Departure]),Month([Departure]),1)=CDate([Forms]![Conciliacao]![boxReferenceMonthGtis]
WHERE CVDate(DateSerial(Year([Departure]),Month([Departure]),1)=CVDate([Forms]![Conciliacao]![boxReferenceMonthGtis]
Does anybody knows how to make this work?
What is even weirder is that I have another query in the same database that I can use WHERE DateSerial(Year([Departure]),Month([Departure]),1)=[Forms]![Conciliacao]![boxReferenceMonthGtis] without any issue!
OK:
It could be that some records have Null for Departure.
So i'm testing sample code and I pasted some online text into a field and i'm getting an error and I have no clue why. Here is the entire method which is throwing the error:
EDIT the error is coming from the assignment. However, there is no
error thrown on any number of other input strings.
CurNodeName = RTrim(CurNodeName)
ADORecordset.Fields.Append CurNodeName, adVarChar, 500, adFldMayBeNull
tempString = XMLValueDecode(CurNodeValue)
ADORecordset.Fields(CurNodeName).Value = tempString
...
Here is the string which is being passed into the method:
Most of the methods of the DoCmd object have arguments ? some are
required, while others are optional. If you omit optional arguments,
the arguments assume the default values for the particular method. For
example, the OpenForm method uses seven arguments, but only the first
argument, FormName, is required. The following example shows how you
can open the Employees form in the current database. Only employees
with the title Sales Representative are included.
Here is the exact error description:
Multiple-step operation generated errors. Check each status value.
That is the whole story, and i just don't understand it. Can you tell me why this error is happening?
(From a comment to another answer:)
There must be some critical difference between adVarChar type and adVarWChar that the text being set responded differently to.
It was many versions ago (Access 2000, and the release of Jet 4.0) that Text and Memo fields in Access were upgraded to handle Unicode. From that point forward, Text fields and parameters needed to be referenced as adVarWChar (with a maximum length of 255), while Memo fields and parameters needed to be referenced as adVarWChar or adLongVarWChar (with a theoretical size limit of approximately 1 billion characters).
It is unclear why the code in the question would work for some strings and not others, but certainly using the correct ("W") data type would be a prerequisite.
Have you checked curNodeName for type? If you've passed a numerical type to append, it might be converting it to string implicitly when naming the field to avoid indexing errors, if that's the case, (and you are inadvertently trying to assign that string to the value of a field with an index that is not currently in the collection,) you might be throwing that multi error because you'd be trying to assign a string of a length longer than the default length to a field with an index way outside the current collection (either of which error alone might throw a specific exception, but depending on the way the parser is handling those terms, it might evaluate each side of the assignment for validity before trying to assign an error code.)
What I'm wondering is if you've debug.printed (or just counted, depending on collection size) the field names and indices as matched pairs and tried assigning the string to your field by index instead of name?
While trying to preview the SSRS report I'm building, I'm getting the below error message:
(processing):Unknown ExpressionType: FieldValue denying ReportItems.
I haven't been able to find anything pertaining to this error anywhere. My report is fairly simple, mostly just lookup expressions referencing connected SQL tables. The only thing that has been added is a string parameter with a set readonly value. I experimented with removing it from the expressions it is used in, but no luck.
Any suggestions?
I had a similar error message and found that I had used a ReportItems!FieldName.Value reference in a Dataset calculated field.
