Why stored procedure is faster than query?
Stored procedures are precompiled and optimised, which means that the query engine can execute them more rapidly. By contrast, queries in code must be parsed, compiled, and optimised at runtime. This all costs time.
Are stored procedures more secure?
5 Answers. They are more secure than what you are doing. Your query is posting raw SQL to the db which means that your parameters aren’t treated as sql parameters but as plain old sql. … A non-dynamic sql stored procedure won’t allow this, because the input parameter won’t execute as extra sql.

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.
Why are stored procedures bad?
Stored procedures require you to reinvent wheels. … Very often, you will end up reinventing these wheels using copy and paste code, which again is a bad practice.
