问题 I'm an ameture using SQL server 2012 and need help with an update query. I have a SQL table showing results. Every result is unique through the date of the event, the ContestID and the rank of the result (1st 2nd 3rd etc.) Every result has allocated points depending on how well they did in the event. Last place, 4th, 3rd, 2nd and 1st have the same points for each event but points between last and 4th are calculated depending on how many results there are. E.g. 7 RESULTS: OLD 1st - 150pts 2nd

I am thinking about creating a stored procedure and then a job that would execute the stored procedure every 5 minutes. My question is, can you make an HTTP request from a stored procedure? Is there a better approach to accomplish this goal? 回答1: I ended up using a CLR function (using C#) to pull the JSON Object from
