Question

Can anyone please help me on the following:

I have created a SQL Server stored procedure as follows:

create procedure prcGet_sub_menu_list
     @sub_menu     char(5)
as
begin
     select
          'menu_code'     =     menu_code
          'menu_name'     =     menu_name
     from sub_menu_master
     where menu_code      =     @sub_menu
end
return

Now i am calling this procedure from VB.NET, but i get an error like ‘Stored procedure prcGet_sub_menu_list expects parameter @sub_menu which was not supplied’. Please help me on the same. The code which i have in VB.NET is as follows:

Imports System.Data
Imports System.Data.SqlClient

Dim sqlConn as New SqlClient.SqlConnection
sqlConn.ConnectionString = "........"
sqlConn.Open()

Dim menuCode as string
menuCode = cboDetails.selectedItem

Dim sqlCmd as New SqlCommand
sqlCmd.Connection = Connection.sqlConn
sqlCmd.CommandType = CommandType.StoredProcedure
sqlCmd.CommandText = "prcGet_sub_menu_list"
sqlCmd.Parameter.Add("menuCode", SqlDbType.Char)

Dim sqlDA as New SqlDataAdapter()
sqlDA.SelectCommand = sqlCmd
Dim sqlDT as New DataTable
sqlDA.Fill(sqlDT)

This is the code that i have written and it gives me the error:
‘Stored procedure prcGet_sub_menu_list expects parameter @sub_menu which was not supplied’.

Please give me some help on the same.

Regards,
George

You have to give the same parameter name and type like in your stored procedure.

  sqlCmd.Parameters.Add(New SqlParameter("@sub_menu", SqlDbType.Char, 5)).Value = "Joe"

Geetha.
