SQL query will be compiled everytime it is executed.
Stored procedures are compiled only once when they are
executed for the first time.

Answer / gayathri

Every query is submited it will be compiled & then
executed.where as stored procedure is compiled
when it is submitted for the first time and this compiled
content is stored in something called procedure cache,
for subsequent calls no compilation,just execution & hence
better performance than query.
In Query we can execute only 1 statement. Stored Procedure:
In Stored Procedure we can execute Batch of Queries

Answer / senthil kumar

compared with query, stored procedure is efficient and fast
execution.Because stored procedure is program once it
formed then execute as a program.

Answer / vial

stored proceure compiles only once and stores in database
managemant system so it is optimized for best performance
while sql query compiles every time and executes using dbms
driver so its performance decreses

Answer / robinson

The execution plan will be created when compiling the stored
procedure and permanently stored in the database and so it
is much efficient, But in the case of query the execution
plan will be created at runtime.

Advantage in Programming - If you are using Query in your
program exe, want to change Query, you have to change query
and compile it again. But if used Stored procedure, no need
to recompile just modify the sp. Query is slow and SP is
fast.

5. In a query memory management is more high than the SP

Answer / kshitij s. nirmaley

query and stored procedure do the same thing but the
difference is that a query should be compiled every time the
query is executed, while the stored procedure is in compiled
form when executed first time .If we use stored procedure
we can avoid recompilation of the query.

Answer / pratap

A stored procedure is a named group of SQL statements that have been previously created and stored in the server database. Stored procedures accept input parameters so that a single procedure can be used over the network by several clients using different input data. And when the procedure is modified, all clients automatically get the new version. Stored procedures reduce network traffic and improve performance. Stored procedures can be used to help ensure the integrity of the database.
CREATE PROCEDURE procedure_name
@param data_type = default_value,
@param data_type = default_value,
@param data_type = default_value
AS

BEGIN
DELETE FROM Employees
WHERE EmployeeId = @EmployeeId;
END

Answer / swathi

Queries are compiled each and evey time when we execute.
where as Stored Procedures are compiled only once when we
execute for the first time and the execution plans are
cached in memory.
