In real world production tuning sometimes a "quick fix" is required. This script will generate index create scripts for any column ending ID which doesn't have an index. It's dirty and its quick but you might just be amazed by the results when run against your database!
--
-- Set to required database
--
use xxxxx
go
--
-- I've used a # temp table so the contents can be saved or viewed
-- if required
--
create table #test2(ObjName sysname,ColName sysname,ObjId int,ColId int)
--
insert into #test2(ObjName,ColName,ObjId,ColId)
select obj.name, col.name, obj.id,col.colid
from dbo.sysobjects obj join dbo.syscolumns col on obj.id=col.id
where col.name like '%id'
and obj.xtype='U'
--
-- remove where an index exists
--
delete from #test2 where convert(varchar,objid)+':'+convert(varchar,colid) in
( select convert(varchar,id)+':'+convert(varchar,colid) from dbo.sysindexkeys )
--
-- put QA into text output
-- cut and paste output to create indexes
--
select 'create index idx_'+ObjName+'_'+colname+' on '+objname+'('+colname+')'+char(10)+'go'+char(10)
from #test2
--
-- once you're happy remove temp table
-- drop table #test2

Indexes directly affect the performance of database applications. This article uses analogies to describe how indexes work. The estimated execution plan feature of the Query Window is utilized to compare the performance of two queries in a batch.

SQL Server 2000 has indexed views, which can greatly improve database performance. However there are a number of restrictions on building the view, including the restriction against outer joins. So how can this work? New author Jean Charles Bulinckx brings us a technique that can help you get around this restriction.

There is nothing spectacular about using indexes per say. However, on many occasions I have come across a variety of SQL coders that never consider validating that the index they think they are using is efficient or even being used at all. We can all put indexes on the columns that we think will be required to satisfy individual queries, but how do we know if they will ever be used. You see, if the underlying table data is constructed, contains, or is ordered in a particular way, our indexes may never be used. One of the factors around the use of an index is its clustering factor and this is what this article is about.
