How can I set default values for my parameters in my web service. For example the employee number needs a default value of -99 for my or statement to search for the record. I would also like to add the default value of " " for the employee&#039;s name. Here&#039;s my code:<BR><BR>&#060;WebMethod&#062;Public Function GetEmployeeInfo(ByVal employeeID As String, ByVal lastName As String) As System.Data.DataSet<BR>Dim connectionString As String = "server=&#039;;; trusted_connection=true; Database=&#039;Northwind&#039;"<BR>Dim sqlConnection As System.Data.SqlClient.SqlConnection = New System.Data.SqlClient.SqlConnection(connectionStri ng)<BR> <BR> <BR>Dim queryString As String = "SELECT [Employees].[EmployeeID], [Employees].[LastName], [Employees].[FirstName],"& _ <BR>" [Employees].[Title] FROM [Employees] WHERE (([Employees].[EmployeeID] = @Employ"& _ <BR>"eeID) OR ([Employees].[LastName] = @LastName))"<BR>Dim sqlCommand As System.Data.SqlClient.SqlCommand = New System.Data.SqlClient.SqlCommand(queryString, sqlConnection)<BR> <BR>sqlCommand.Parameters.Add("@EmployeeID", System.Data.SqlDbType.Int).Value = employeeID<BR>sqlCommand.Parameters.Add("@LastName ", System.Data.SqlDbType.NVarChar).Value = lastName<BR> <BR>Dim dataAdapter As System.Data.SqlClient.SqlDataAdapter = New System.Data.SqlClient.SqlDataAdapter(sqlCommand)<B R>Dim dataSet As System.Data.DataSet = New System.Data.DataSet<BR>dataAdapter.Fill(dataSet)<B R> <BR>Return dataSet<BR>End Function
