c# - Calling stored function using user input variable -

-

Newbie here I am creating a web app in C # which uses the database to display results through a variable located within a dropdown.

So far, I have a procedure that looks like the following; 

  Use [Energy Expansion] Go SET ANSI_NULLS Go to go to the conversion process QUOTED_IDENTIFIER [dbo]. [getbysID] @SchoolID int select as * invoice from energy where dateID by schoolID = @ schoolID;   
 My question is, can the "School ID" represent a variable from the webpage? For example, the user selects a school from the dropdown, which sends a variable of "schoolID = 1" to represent a specific school. Does SQL school interpret properly? Or should I do some different way?  
 EDIT: Sorry for the awesome format here, I'm very new to this.

I am trying to implement a screen-scraps application that opens a URL in which a parameter changes as it is for a loop: var data = [ '100', '101', '102', '103', '104']; (Var indexA = 0; indexA & lt; data.length; indexA ++) for {Phantom Generation ({'port': freeport}, function (pH) {ph.create page (function (page) {page.open ("http: //...++ data [index B] +" ...

Data is verified in scrap HTML and from index to array Matches. So in page 101 I scrap '101 and retrieve' and pu
