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,

better performance than query.

plan will be created at runtime.

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
DELETE FROM Employees
WHERE EmployeeId = @EmployeeId;

Queries are compiled each and evey time when we execute.
where as Stored Procedures are compiled only once when we

cached in memory.
