Quick SQL Server 7.0 Index Question
Jul 23, 2005
At the moment I only know enough about SQL Server to create the databases I
need as a backend for the various internal desktop/web applications I write.
I haven't ever had the time to get seriously involved with internal workings
of SQL Server and we are far too small to employ a DBA.
With any new application performance isn't a problem as the number of
records is very low. Over the life of the application the number of records
obviously increases and performance can start to suffer. My normal cure is
to use the Query Analyzer to suggest and implement indexes that normally get
things back up to speed.
I was wondering whether SQL Server automatically keeps the created indexes
up to date or do I need to be doing anything else either manually or as a
scheduled job? The databases all have auto create statistics and auto update
statistics enabled.
Any pointers gratefully received
Thanks
Alan

Hi all,
I apologize in advance for the lack of homework before posting, but I am just looking for a quick answer, or a quick point in the right direction to figure this out.
I have a developer from an adjacent team that wants to use Reporting Services in a SQL Server 2005 installation.
From what I found online during what I thought was a definitive search yesterday, I gave him the MSDN SQL Server 2005 DVD and told him that Reporting Services is now part of the standard installation. Which is what my brief search yesterday indicated to me.
He did the installation (full, according to him) and said he could not find Reporting Services.
So, the quick question is...
Where is Reporting Services in SQL Server 2005? I don't have a separate MSDN DVD that contains it as was the case on SQL Server 2000. This further supports my (wavering) position that it is part of the standard installation.
Thoughts? Direction? Collective kicks in the posterior?
Thanks!

Hey guys... i cant figure this out for the life of me. I have a long T-sql query, and when i enter the string "Rental" into the Listingtype, it says invalid column name "Rental" ... im not looking for the value to be a column, im looking for it to match the value in the ListingType column... here's the query:

For a query like below ...
How do i have to select only the latest revisions,
if i need to filter last current revisions of each document ...
where the revision could be either alphabetical or even numerical ...
Presently I get all revisions with the below query ...
Note: csd_revi is the field of CSD table for revisions.
---
select distinct
csd1.csd_orig + csd1.csd_subj + csd1.csd_type + csd1.csd_numb + csd1.csd_revi as "Document Reference No.",
csd1.csd_labl + ' ' as "Description"
from
E0437csd csd1,
E0437tra tra1,
E0437csd csd2,
E0437trd trd1,
E0437apr apr1,
E0437apc apc1,
E0437tra tra2,
E0437csd csd3,
E0437trd trd2
where
csd1.csd_orig = 'BS' and
csd1.csd_subj like '%WN1%' and
csd1.csd_type = 'D' and
tra1.tra_drgn = csd1.csd_orig + csd1.csd_subj + csd1.csd_type + csd1.csd_numb + csd1.csd_revi and
tra1.tra_part = 'PARSO' and
tra1.tra_type = 'A' and
csd2.csd_orig + csd2.csd_subj + csd2.csd_type + csd2.csd_numb + csd2.csd_revi = tra1.tra_trno and
trd1.trd_trno = tra1.tra_trno and
trd1.trd_cc = '0' and
trd1.trd_part = 'PARSO' and
apr1.apr_docu = csd1.csd_orig + csd1.csd_subj + csd1.csd_type + csd1.csd_numb + csd1.csd_revi and
(apr1.apr_stat = apc1.apc_code or apr1.apr_stat = '') and
tra2.tra_drgn = csd1.csd_orig + csd1.csd_subj + csd1.csd_type + csd1.csd_numb + csd1.csd_revi and
tra2.tra_part = csd1.csd_ownr and
csd3.csd_orig + csd3.csd_subj + csd3.csd_type + csd3.csd_numb + csd3.csd_revi = tra2.tra_trno and
trd2.trd_trno = tra2.tra_trno
order by
csd1.csd_orig + csd1.csd_subj + csd1.csd_type + csd1.csd_numb + csd1.csd_revi

If I have:
Table Test
TestID (PK)
PretestTech (FK IndividualID)
PostTestTech (FK IndividualID)
ProjectManager (FK IndividualID)
TestInfo
Table Individuals
IndividualID (PK)
Initials
First
Last
Is there an efficient way to query for a list of tests with the PretestTech,PostTestTech,and Project manager initials? I guess I'm stuck because I want to Join the Test and Individual tables but there are three fields that need to be joined. So this is the only way I can think to make it work:
SELECT
TestID
,TestInfo
,(SELECT Individual.Initials FROM Individual WHERE Individual.IndividualID = Test.PretestTech) AS 'PretestTech Initials'
,(SELECT Individual.Initials FROM Individual WHERE Individual.IndividualID = Test.PostTestTech) AS 'PostTestTech Initials'
,(SELECT Individual.Initials FROM Individual WHERE Individual.IndividualID = Test.ProjectManager) AS 'ProjectManager Initials'
FROM Test
Is this efficient or should I rethink my Table design?
Thanks
