The queries are more flexible, as you have complete control over every aspect of the query. Store procedures only give you as much control as the inputs allow.  The benefits of stored procedures are code re-use, execution plan re-use, and security ( you don't have people/program's directly interacting with the data - you can define how, what and who can interact with the data)

Hi,

With the plan reuse you eliminate the compile time. Often this is small compared to the execution time. However I heard a story that compile time was 3 minutes, vs 10 seconds execution time.

So, generally, benefit of stored procedure is more control. Benefit of query is more flexibility.

this is an often discussed question, as a sample:

you have to ask first:
What are the differences between stored procedures and raw queries?
after that, like @PortletPaul posted, you need to understand "The Pros and Cons of Stored Procedures"...

for example, a really bad use of stored procedures:

USE MyDatabase;
GO
DECLARE @my_result int;
DECLARE @SomeNumericValue int;
SET @my_result = 0;
DECLARE my_cursor CURSOR FOR SELECT SomeNumericValue FROM SomeTable;
OPEN my_cursor;
FETCH NEXT FROM my_cursor INTO @SomeNumericValue;
WHILE @@FETCH_STATUS = 0
BEGIN
   SET @my_result = @my_result + @SomeNumericValue;
   FETCH NEXT FROM my_cursor INTO @SomeNumericValue;
END
CLOSE my_cursor;
DEALLOCATE my_cursor;

SELECT @my_result as my_result;
GO

in this case is better a raw query like :

SELECT SUM(SomeNumericValue) as my_result FROM SomeTable;

if you need to perform more that 1 query - like ADO, it handles multiple recordsets - and/or no just select commands, than you can use stored procedures.
