I've been banging my head against this for a while now.
I have a function that retrieves fields from a table and populates inputs from them, however when I try to execute the function I receive an error saying "Procedure or function 'Quad_GetAllFields' expects parameter '@subWeek', which was not supplied".
I know I am supplying the parameter, as I can access it from any point in the function.
The function is:
Protected Sub setAllFields(ByVal myConnection As SqlConnection, ByVal subWeek As String, ByVal site As String)
Dim myCommand = New SqlCommand("Quad_GetAllFields", myConnection)
myCommand.Parameters.AddWithValue("@subWeek", subWeek)
myCommand.Parameters.AddWithValue("@site", site)
Dim myDataReader As SqlDataReader = myCommand.ExecuteReader()
If myDataReader.Read() Then
'populate fields
End If
End Sub
And the stored procedure is:
ALTER PROCEDURE dbo.Quad_GetAllFields
(
@subWeek VARCHAR(50),
@site VARCHAR(20)
)
AS
BEGIN
SELECT TOP (1) ID, Priority1, Priority2, Priority3, Priority4, Highlight1, Highlight2, Highlight3, Highlight4, Update1, Update2, Update3, Ahead1, Ahead2, Ahead3, Outlook1, Outlook2, Comments, Site, Week, Submitted FROM Charts WHERE Week = @subWeek AND Site = @site ORDER BY ID DESC
END
Any help on what I'm doing wrong?
I'm fairly new in working with stored procedures, but I still can't find the problem.
Thank you
You have to set the SqlCommand's
CommandType
property to StoredProcedure
, default is Text
:
Protected Sub setAllFields(ByVal myConnection As SqlConnection, ByVal subWeek As String, ByVal site As String)
Dim myCommand = New SqlCommand("Quad_GetAllFields", myConnection)
myCommand.CommandType = CommandType.StoredProcedure
myCommand.Parameters.AddWithValue("@subWeek", subWeek)
myCommand.Parameters.AddWithValue("@site", site)
Dim myDataReader As SqlDataReader = myCommand.ExecuteReader()
If myDataReader.Read() Then
'populate fields'
End If
End Sub
If your string parameter, @subWeek, is null you can get this error.
If your string is null, you need to pass DBNull.Value for @subWeek.
Try hard-coding a @subWeek value
myCommand.Parameters.AddWithValue("@subWeek", "Myvalue")
This should work fine.
