I'm using a SQL Server 2008 stored procedure to create a new record with this syntax:
cmd.Parameters.Add("@photo", DBNull.Value)
cmd.ExecuteNonQuery()
but the result is a:
Operand type clash: nvarchar is incompatible with image
Photo is not the only parameter but is the only image one, I am not passing a nvarchar but a null value, am I missing something?
I got the following error , when i am trying to insert data into the table and having the image type field.Operand type clash: image is incompatible with varchar(max)
View 1 RepliesI am working with TVP and I am trying to pass a data table to the stored procedure as TVP. When the command tries to ExecuteNonQuery it throws an error:Operand type clash: datetime2 is incompatible with int. The data for table-valued parameter "@tvpPermitWork" doesn't conform to the table type of the parameter.I checked the data table using the visualizer and I find all the data to be correct. I am now stuck and I don't have the time to change it to stored procedures with individual parameters.

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:

travelQuery.Parameters.AddWithValue("@trip", travelParameter)

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 try that code, and it just throws me the error that type Icon cannot be converted to Image. So how do i get around this? And does "ExtractAssociatedIcon(exefile)" work on exe files? Admittedly i don't really know what im doing

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.
I have DateTimePicker, and when I execute this procedure:

"WHERE TOT_DATE = '" & Me.DateTimePicker1.Text & "'"

With XP set to a language such as Spanish (Spain), the VBA-in-Excel function "Excel.Version" returns the text string "11.0" (not "11,1"). It does not respect the language setting.
"CLng(Excel.Version)" then produces the value "110" (wrong!), perhaps because CLng respects the language setting and is looking for a comma instead of a period.
The work-around is easy. But I need to know if switching to another language requires a setting that my client in Spain missed, or is this just a bug.
If it is a bug, is the problem limited to this one function (Excel.Version), or are there other functions that return values in text format that are affected?

View 1 RepliesWhy does this:Private [Function] As Func(Of Double, String) = Function(ByRef z As Double) z.ToString
gives the following error:Nested function does not have a signature that is compatible with delegate String)'.
While this:Private [Function] As Func(Of Double, String) = Function(ByVal z As Double) z.ToString
Does not? (The difference is ByRef/ByVal)
Furthermore, how might I implement such a thing?
Solution at the bottom. I receive the following error when trying to update records: Must declare Scalar Variable @PaymentTermID Problem is, @PaymentTermID should be defined already in the Update parameters. The 2 functions for onrowdatabound and onrowupdate are tweaked versions of the ones found here for the DropDownList: GridViewRow.DataItem Property. Delete works fine. No new lines are added, just names changed around. I am not exactly used to working with asp objects.
