How can I use longer variables in my sql procedures?
I have a stored procedure which operates with an @parameter which I call using the attached code. The variable nameTable is is the name of the current database table that I want the procedure to use. When I run the code I get an error saying "Conversion from string "Table1" to type 'Integer' is not valid."
I tried editing the procedure from "@parameter1 int" to "@parameter1 str" but it causes an error.

Dim nameTable As Integer = Table1
cmdProcedure.Parameters.Add(New SqlParameter("@parameter1", nameTable))

Hey, I changed to vchar128 like you said and I now get this error:
Conversion from string "Table1" to type 'Integer' is not valid.
I have attached the full code below for you to see. I appreciate you trying to help!
P.S in the procedure editor, the data type is "@parameter1 varchar(128)," as you told me to put.

Public Class RateBox
Private Sub OK_Button_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles OK_Button.Click
Dim scoreRating As Integer = ListBox1.SelectedItem 'this is the rating score out of 5'
Dim cnPubs As New SqlConnection("Server=MARK-HOME\SQLEXPRESS;Database=Library;Integrated Security=SSPI;")
Dim nameTable As Integer = "Table1"
cnPubs.Open()
Dim cmdProcedure As New SqlCommand("dbo.StoredProcedure1", cnPubs)
cmdProcedure.CommandType = CommandType.StoredProcedure
cmdProcedure.Parameters.Add(New SqlParameter("@parameter2", scoreRating))
cmdProcedure.Parameters.Add(New SqlParameter("@parameter1", nameTable))
cmdProcedure.ExecuteNonQuery()
Form1.JackBennyTableAdapter.Fill(Form1.LibraryDataSet.JackBenny)
Me.Close()
End Sub
Try switching lines 9 and 10 ...
What does the header of the stored procedure look like ?
My guess would be:
create procedure dbo.StoredProcedure1
@parameter1 varchar(128)
, @parameter2 int
as
...
