I am trying to create a report in MS Visual Studio and use the DateClosed as a parameter so that a user can select on 'DateClosed'. The error I am getting says:
Error Message: Conversion failed when converting date and/or time from character string.
The select satement is below is based on a view that I had to convert a string (DateClosed) to a datatime data type.
SELECT GrantNumber, GrantAmount, GrantDate, NatureOfGrant, SpecialInstructions, FullName, GMP, GrantType, Name, DateClosed
FROM V_WSF_GrantMakingPartnersGrants
ORDER BY DateClosed DESC
I am really confused because the 'ClosedDate' above is returning the value as a datetime data type. I can't cast it again, because it already sees it as a date. This is making no sense to me.
Can anyone tell me how to add the parameter into MS Visual Studio?
It's not clear where you are getting the data from - SQL Server or Oracle? So you want to pass the date? Ie, you enter 02/02/2012 and then click to generate report?
If you are passing to Oracle, you might have to use the sql function TO_DATE(xxxx). The same thing may apply to SQL Server but that is not an area I'm not familiar with. Therefore:
..order by DateClosed may have to read like this:
to_date(DateClosed, 'yyyy/mm/dd')
The 2nd parameter - must match the date format that you are sending in...
I hope this helps...
I think you should use the dateTime.formate to specify the format type on the dataBase..
like "YYYY-MM-dd". make sure the format is the same date format you are using on your DataBase string date.
I think this will solve your problem.

I build a dynamic Dictionary in ClickHouse DB. It will create the dictionary before the SQL commands execute. Also, the dictionary name was created at the same time.
The dictionary name was a combined string by date and table name. Because I don't want to keep so much data in the long-term dictionary, the short-term Dictionary could be a great help to release the memory after maybe an hour when no one is using it.
And the error happened.
When I use the dictionary in my SQL commands it is okay with solid commands.
e.g.
dictGet(CONCAT('2022-04-06', 'MyTableName'), 'GetBackColumnName',myKeyColumn) AS col_name
But when I change to using the column from Table, it was broken.
e.g.
dictGet(CONCAT(DATE_COL, 'MyTableName'), 'GetBackColumnName',myKeyColumn) AS col_name
And the error message shows up.
Illegal type String of the first argument of function dictGet,
expected a const string.
Does anyone know how to fix the issue?
My CH version is: 20.8.7.15
I try to find the resolution from the ClickHouse office report but nothing can fix this issue. And I tried lots of functions of String to figure out what happened.
Hello everyone and happy new year,
I'm converting my project to use SQL Server instead of MySQL and I'm struggling with the problem of managing timestamps.
In the project, I have this code:
Customers::whereBetween('created_at', [Carbon::now()->subDays('7'), Carbon::now()])->count();
which gives me back the number of new customers registered in the last 7 days.
Using MySQL no problem whatsoever while with SQL Server I get this error:
Converting an nvarchar data type to datetime resulted in a value
outside of the allowable range.
despite in my model, I have set
public function getDateFormat()
{
return 'Y-m-d H: i: s.v';
}
to get the values in milliseconds.
What did I forget to set up?
The error tells you that a conversion failed. Possible reasons:
The date does not exist
If you get February 30th as the input, it will fail.
Input not complying to the format in use
To detect whether this is the problem, you will need to find out what the generated SQL is and find out which value caused this problem. After carefully studying the conversion you should be able to determine what the problem and solution is.
The following conversion is not working. I would like to see if anyone can be able to solve it.
Syntax:
ToText(Date({db.field}),"dd/MM/yyyy")
System is saying that the date id is required.
however ToText( Date({db.field}), "dd/MM/yyyy") is working fine....
the other simplest way is :
Crystal Report Design Window->Right click on date field->format Field->Customize the date format as you want to.
I am creating a report in MS Visual Studio 2008 epxress. The dataset should be limited using parameters. I want the users to have the ability to choose a starting date and then name the number of years into the future they want to see the data.
I created 3 parameters
1. fromdate (Type:Date/Time; visible): This is where they choose a date
2. futureyears (Type: Integer; internal): This is where they should write the number of years into the future
3. todate (Type: Date/Time; internal): This is an internal parameter with the following function as the default value:
=dateadd(DateInterval.Year,Parameters!futureyears.Value,Parameters!fromdate.Value).
fromdate and todate are then used in the query of the dataset to limit the data.
The following error appears when I try to preview this:
"The DefaultValue expression for the report parameter 'todate' contains an error: The expression that references the parameter 'futureyears' does not exist in the parameters collection. Letters in the names of parameters must be use in the correct case"
The thing is: The parameter "futureyears" does exist, when I write the function for the default value of todate, I choose it from the parameters section. so it is there.
I tried to run this report without the futureyears parameter and typed in a random number in the dateadd function. Without the parameter in question, the report runs fine. the problem must be the parameter "futureyears", but I don't know where the problem is. Thank you for your help.
I just figured out the answer myself. Leaving this here in case anyone has a similar problem.
In the parameters folder, the "futureyears" parameter was listed UNDER the "todate" parameter.
All I needed to do for it to work was shift the futureyears parameter ABOVE the todate parameter. Now the report runs fine.
This is my first attempt to create a Visual Studio 2008 report using parameters. I have created the dataset and the report. If I run it with a hard-coded filter on a column the report runs fine. When I change the filter to '?' I keep getting this error:
No overload for method 'Fill' takes '1' argument
Obviously I am missing some way to connect the parameter on the dataset to a report parameter. I have defined a report parameter using the Report/Report Parameter screen. But how does that report parameter get tied to the dataset table parameter? Is there a special naming convention for the parameter?
I have Googled this a half dozen times and read the msdn documentation but the examples all seem to use a different approach (like creating a SQL query rather then a table based dataset) or entering the parameter name as "=Parameters!name.value" but I can't figure out where to do that. One msdn example suggestted I needed to create some C# code using a SetParameters() method to make the connection. Is that how it is done?
If anyone can recommend a good walk-through I'd appreciate it.
Edit:
After more reading it appears I don't need report parameters at all. I am simply trying to add a parameter to the database query. So I would create a text box on the form, get the user's input, then apply that parameter programmatically to the fill() argument list. The report parameter on the other hand is an ad-hoc value generally entered by a user that you want to appear on the report. But there is no relationship between report parameters and query/dataset parameters. Is that correct?
My last assumption appears to be correct. After 30 years in the industry my bias is to assume a report parameter actually filters the SQL data using the given parameter. This is not the case with .rdlc files used by Report Viewer. These report parameters have nothing to do with fetching data. Sounds like this was a design decision on Microsoft's part to completely separate the display of data from the fetching of data, hence, Report Viewer has no knowledge of how data may be fetched. Best way for me to conceptualize this dichotomy is to think of Report Parameters more as Report Labels, quite distinct from the dataset query parameters.
