Which is better stored procedure or function?
We conclude that the table-valued functions are more flexible to filter results horizontally and vertically, to use a select into. Stored procedures are less flexible to reuse the results. In terms of performance, table-valued functions are a good choice. The performance is basically the same than stored procedures.
What is difference between stored proc and query?
What is the difference between a query and stored procedure? query and stored procedure do the same thing but the difference is that a query should be compiled everytime the query is executed,while the stored procedure is in compiled form when executed first time.
