Asp.net - Conversion Failed When Converting The Nvarchar Value '01:00' To Data Type Int

Oct 17, 2011

I don't know how to convert the nvarchar value into an int, but that is the way it needs to be set up. I've found other posts about this but I don't know how to use CAST in the INSERT statement I have. All the posts I could find were about converting to int in SELECT statements. I need this statement to change the field @Duration to an int in the database. @Duration is an amount of time. (01:00, 02:00...) They will all get rounded up to the next int value. So if a user enters 0:45, it should be converted to 1. how to get this INSERT to work?

Conversion Failed When Converting DateTime From Character String

Feb 11, 2011

I have two datetimepickers on my form to set a start date and end date for a SQL server database query. I am passing these dates with parameters to my query from the .Value of the datetimepickers. When I run the program, the code returns an error of "Conversion failed when converting datetime from character string" I am not converting anything in my code. It is my understanding that the StartDatePicker.Value is already a datetime and does not require conversion.

Here is some code:
'Define Wages_Query
Dim Wages_Query As String = _
"SELECT [Department], [Operation_NUM], sum(STWag) as [STwag], SUM(OTWag) as [OTWag]," & _
" SUM(Shift_Diff) as [Shift_Diff]," & _
" SUM(COALESCE(STWag,0) + COALESCE(OTWag,0) + COALESCE(Shift_Diff,0)) as [TotalWages]" & _
" FROM dbo.Financial" & _

Error : Conversion Failed When Converting Date And/or Time From Character String

Mar 27, 2011

The error is: Conversion failed when converting date and/or time from character string.Basically I'm trying to make it so that when someone clicks a location in a list box it increments the correct field in a Stats table by 1 to say that they clicked the location. I've been trying to solve this for a while now and can't get anywhere. My date is in date format, and so is the Date field in my Stats table. My code can be seen below.

Dim Current As String
Dim Check As String
Dim objCmd2 As Object

[code]....

The issue comes in with the second SQL statement I think. I don't understand why adding a date into a date field would be an issue, I've tried adding it as a string which didn't work.

Conversion From Type 'DBNull' To Type 'Decimal' Is Not Valid When Field Has Data?

Feb 7, 2012

I am pulling data from a local MSSQL database using a stored procedure, then send the data to a web service. Every part of the component works well except for a pesky problem will a DBNull being returned from the DataRow field, when I know that the field is not null and has valid data. The database and associated INSERT statements that add to this field are designed to not allow NULL entries. When I debug break the program on or right before the line that throws the error I see that the field has valid data for the current row.If I add a null check to the code (as below) the operation continues as normal:

Dim dataResultsTable = Me.myViewTableAdapter.GetData(int)
For Each myDataRow In dataResultsTable.Rows
If worker.CancellationPending Then

[code]....

Why is the read operation returning DBNull instead of the data in the database?

EDIT: Just to be clear, the operation does return the proper data, but the data is not being saved into the variable.

Asp.net - Declaring A Nvarchar In VB/Matching An Nvarchar In A SQL Query?

Apr 22, 2009

I'm working on an ASP.NET application that uses VB. I'm using a SQLReader/SQLCommand/SQLConnection within the VB file to try to pull data values.I was mystified to find out that the reason why the query wasn't returning any values, and someone here showed me how to troubleshoot the query to verify things were being returned, which they weren't.

I talked to a co-worker, and he asked if it would match because I was feeding a string, and the Text field for the database is an nvarchar. How can I declare the variable in VB so that when fed in as a parameter for the query, it can match?The types of data it looks to match are just basic things like "2", "2a", "1a", and so on.If there's no way to just declare the nvarchar, does anyone have a suggestion on how I might workaround that?

Side note: This is a continuation, of sorts, of this question: http://stackoverflow.com/questions/768052/sql-reader-saying-no-values-exist-query-seems-fine

Edit: I set things up like you guys said, but now I'm getting an error that "No mapping exists from object type System.Data.SqlClient.SqlParameter to a known managed provider native type. "I have the parameter as a form-wide variable like this:

Private travelParameter As New SqlParameter("@trip", SqlDbType.NVarChar)

And then inside the main form,

travelQuery.CommandText = "SELECT [StartLoc], [EndLoc],[TravelTime], [AvgSpeed], [Distance] FROM [TravelTimes] WHERE [TripNum] = @trip"
travelQuery.Parameters.AddWithValue("@trip", travelParameter)

Option Strict And Data Type Conversion

Mar 2, 2011

Just wondering what the preferred/practised data type conversion technique is?

For example I recently enabled option strict, which in turn found quite a few errors in relation to data types, vb.net prompted me to use CType, which is fine.

However, I have seen other functions for data type conversion, such as .tostring, CInt , Convert, integer.parse and also Ctype.

Why would you use Ctype over the others?

I know its a pretty primitive question , but why do so many conversion methods exist?

Get Nvarchar Data From SQL Server Database?

Jun 11, 2012

I'd like to get some values from nvarchar column (SQL Server database). My code looks like below:

Dim value1 As String
Dim con2 As New System.Data.SqlClient.SqlConnection
con2.ConnectionString = "data source=AAA;initial catalog=DWH;integrated security=SSPI;"
con2.Open()

[code]....

It works fine only when there are numeric values in the column. But in this column are stored variable characters values and this types of values are not being displayed on the page. I don't know what is the reason.I've tried to use getValue.ToString instead of getString but it doesn't work either.
