From SQL to HTTP post?

So I have a SQL (Sybase) DB that we recieve "reads" into. These reads contain information such as reader, datetime, employee id ..... I need the ability to post some of the information contained in this table and another table (cross referenced by said employee Id) to an http post. I need this to happen on insert of information to said table. What'd be the best route to do this? Can an http post be done with just a stored proceedure in SQL or would I need another program to accomplish this?

Thanks.
