How to tune a stored procedure?..

Answer / arun yadav

There could be 'n' reasons for slow performance. For tuning
the performance of a SP we need to know how much resources
it is using and how much time it takes in execution. We can
check this using the performance monitor (for example, RPC
Counter) and execution plan. Check if we are using
appropriate joins, table defrag, index rebuilt can be the
solutions.

How to tune a stored procedure?..

Answer / virgilio

The statements from above are correct but one main thing
that might speed a proc up is the naming convention.
If you create a user defined Storproc and you name it by
using the "Sp_" prefix SQL thinks is a System Store Proc
and goes to the Master DB to look for the Object instead of
looking locally.

How to tune a stored procedure?..

Answer / arindam choudhury

suppose the query is correct in astored procedure then
1)we need to use tablename with (nolock) in our select
statements so that it does not create delay if other person
is updating the table at the same time it will show last
updated table recordset
2)if we dont need that much the database server to return
the number of records affected after executing any dml
statements which actually reduces the performance ,we can
use set nocount on -set nocount off before and after
writing the sql query,
3)wecan create lesser join statements if we can use
subqueries

these are the few steps to tune stored procedure

How to tune a stored procedure?..

Answer / neethu mohanan

stored procedure is used to write queries,if there is an
error in the query it willnot be saved.In this if there is
any parameters first declare it,and then the query is write.
Each stored procedure could have a name.We can create the
stored procedure for any tables in the database.
create database->create table->stored procedure.
format:

(stored procedure name)
(@parameter1 type(size),@parameter2 type(size))

//(query)
insert into tablename values(@parameter1,@parameter2 )
