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?

I have a sql select statement with something like:
select... where column in (@Parameter)
In VB code a set parameter.defaultvalue to "65555,67803", But i get an error "Conversion failed when converting the nvarchar value '65555,67803' to data type int."
I am trying to create stored procedure that gone return varchar value, and that value I need to display in textbox.This is the code for stored procedure:
Create PROCEDURE Status @id_doc int, @Name varchar(50) OUTPUT AS select @Name =items.name from Doc,Items where @id_doc=IDN and doc.IDN=Items.ID return @Name
This is the code in vb.net where i need to display returned value from procedure in textbox:
Public Sub Current() Dim dtc As New Data.DataTable Dim dr As SqlClient.SqlDataReader
[code]....
When I try to execute this code I get this message in exception:
"Conversion failed when converting the varchar value 'Blue color' to data type int."
I don't understand where else it could be screwing up. I'd love to be able to keep it to a null value if it is one already, I'm just trying to get it to take anything right now and this is where I'm at.
am using visual basics to develop a search on my project using the date picker but any time i try to search for a date on my SQL database i received the following error message from my programme. "Conversion failed when converting data and/or time from character string "
when running my program I get the following error:Conversion failed when converting date and/or time from character string. After playing a round with breakpoints I discovered the error to appear during:
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" & _ [Code] .....

I'm trying to insert data into a table in my database. I'm using MS Visual Studio 2005 with SQL Express/I get the error message: "Conversion failed when converting from datetime to character string". [code]
When using INSERT INTO statement to SQL 2008 R2 to a column with data type as date and the data I am taking from a DateTimePicker control with date format as short. When my system date format short set to dd/MMM/yyyy the INSERT INTO statement is working perfectly but when the system date format short set to dd/MM/yyyy I am getting the above error.I tried by changing the control format to custom and dd/MMM/yyyy but still the same error is coming.I am using VB2010 and SQLExpress 2008 R2 SP1?
here is an sql query statement i run in vb.net. i keep getting the error of "Conversion failed when converting date and/or time from character string." whenever i try to execute this. the datatype of filing_date and approvale_date is "text" but the deyt variable is originally Date, converted to string: (Date.Today).ToString, like so. nulll is simply a variable with vbNullChar as its value.
Dim a As String a = "INSERT INTO tblVisitor(Name, Sex, TimeIn, EnterDate) VALUES('"& txtName.Text &"', '"& cboSex.Text &"', '"& Now() &"', '"& DateTime.Parse(cboEnterDate.Text) &"')"

Which cboEnterDate is my DateTime Picker. Then I got the message:Conversion failed when converting date time from character string.
I am developing a Windows application for restoring specific databases from our Production platform to "field" tablets by using backups that are taken daily to disk. To preclude "orphaned users" on the tablets, I want to extract the "user name", "password" (hashed) and "sid".I am calling the MS Stored Procedure "revlogin" that produces screen text to copy and paste into a query to recreate those users on another SQL server instance.
IF (@denylogin = 1) BEGIN -- login is denied access SET @tmpstr = @tmpstr + '; DENY CONNECT SQL TO ' + QUOTENAME( @name )

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

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.
Dim i as integer For i = 0 to 365 sqlinsert.InsertCommand="insert into cashdate (date) values (getdate()+'" & i & "')"[code]....
getdate is a function in the database that returns the datetime of now i have an error that says conversion failed when converting date or time from character string .what to do now ??
there is one search button to see the report on datagridview using year..so when the more items are there in database correspond it year(say 2012)... the above exception is thrown by filling the datgridview,the problem happens when it tries to connect with crystal report,it shows error...Remember that i face this problem only if there are more records in my database(exactly more than 100 rows)...when i delete few rows from the database,it works fine..I have created a table and added that table to a dataset,then assigned that table1 as datasource for crystal report

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.
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?

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)
I have a program that calculates commission, but if the commission is nothing then I do not want it to show a zero commission. I want a message box to show a message that there is no commission earned.

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?

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.
