Hello,
we are using Sql Server 2005 Managament Studio.
Can someone tell me how I can script out all DROP/CREATE INDEXES for a particular database?
We only want to script out the INDEXES, not the tables.
Please advise.
Thanks.

Hi,
I'm currently migrating to Sql 2005 from 2000 and have a quick question about indexes.
In 2000 i used to click on Table > All Tasks > Manage Indexes... to view and create all my table indexes. There doesn't seem to be anything similar in 2005 Management Studio. I thought it was under Table > Modify but there's nothing there for indexes. I've had to create all my indexes manually through t-sql but this doesn't help when needing to view and manage current indexes.
Can anyone help me on this?
What is Indexes in SQL Server? Where we use ?? How to use?
I need little explanation about this topic with any sample code.
Thanks in advance.
I'm working to improve performance on a database I've inherited, and there are several thousand indexes. I've got a list of ones which should definitely exist within the database, and I'm looking to strip out all the others and start fresh, though this list is still quite large (1000 or so).
Is there a way I can remove all the indexes that are not in my list without too much trouble? I.e. without having to manually go through them all individually. The list is currently in a csv file.
I'm looking to either automate the removal of indexes not in the list, or possibly to generate the Create statements for the indexes on the list and simply remove all indexes and then run these statements.
As an aside, when trying to list all indexes in the database, I've found various scripts to do this, but found they all seem to produce differing results. What is the best script to list all indexes?
Hi all,
Recently, I upgraded one of our database servers from SQL 2000 to SQL 2005. At the moment, all the databases are in 80 compatibility mode. I upgraded them based on the false pretenses that I could perform online reindexing right off the bat. Apparently, that isn't the case, and it requires switching to 90 compatibility. My question is if I switch to 90, will all indexes be invalidated/unusable? Or will I be able to switch to 90 and perform the online reindexing right away with no downtime?
We have a few 24/7 production VLDB's in the mix (one of which is on this newly upgraded server), and only reasonable downtime is possible. The largest window of downtime I have is about 10 PM - 5 AM with prior notice.
The upgrade was performed using SAN-based LUN's with a detach/reattach.
Thanks,
Matt
I'm currently planning disk layouts and use for a new version of ourdatabase. The current version has all data and indexes in the defaultfilegroup, placed on one big raid-5 array(6 drives) along with thetransaction log. Performance is not the best, as you may imagine...Next week we will add another 14 drives and organize them in differentcombos of raid-10 and raid-1, and then create several filegroups andplace tables and index data on separate physical drives.Most of the database will be placed on a raid-10 array, and some parts(tables/indexes/translog) will have their own raid-1 drives.I've been playing with the rather incorrect idea of using raid-0 insteadof raid-1 on one or two of the new disk arrays we're adding and thenplace (some) indexes on those drives.The theory is that even if one drive fails, the db will stay up and itwill be easy to recreate the indexes when the disk has been replaced.(We will have one hot spare available)Does anyone know how well sqlserver 2005 handles disk loss in such aconfiguration?Any other comments? ;-)boa

Recently moved a couple of dbs from SQL 2000 -> SQL 2005 (different machine). Just restored the dbs on the new server from a full backup of the old one. Everything is fine but...
Some queries are returning out-of-order results (for records added since the migration). I tracked this down to the indexes. I completely rebuilt and reorganized the indexes (online) through the manager interface. This helped provide correct ordering for existing records, but new records added since the re index are still out-of-order.
Looking for a way to permanently fix the indexes so I don't have to constantly rebuild them.
Thanks.
Hi everyone, I am trying to upgrade a 2000 DB to 2005 with SSIS Database Transfer.
I finally got it to work with an online transfer but the destination database has no primary keys, indexes or identity columns from the source DB.
What am I missing?
What other ways are there to upgrade a SS2000 DB to 2005?
Thank you.
So I'm reading http://www.sql-server-performance.com/tips/clustered_indexes_p2.aspx and I come across this:
When selecting a column to base your clustered index on, try to avoid columns that are frequently updated. Every time that a column used for a clustered index is modified, all of the non-clustered indexes must also be updated, creating additional overhead. [6.5, 7.0, 2000, 2005] Updated 3-5-2004
Does this mean if I have say a table called Item with a clustered index on a column in it called itemaddeddate, and several non-clustered indexes associated with that table, that if a record gets modified and it's itemaddeddate value changes, that ALL my indexes on that table will get rebuilt? Or is it referring to the table structure changing?
If so does this "pseudocode" example also cause this to occur:
sqlstring="select * from item where itemid=12345"
rs.open sqlstring, etc, etc, etc
rs.Fields("ItemName")="My New Item Name"
rs.Fields("ItemPrice")=1.00
rs.Update
Note I didn't explicitly change the value of rs.fields("ItemAddedDate")...does rs.Fields("ItemAddedDate")=rs.Fields("ItemAddedDate") occur implicitly, which would force the rebuild of all the non-clustered indexes?
I'm trying to automate an auto-export of a table on a daily basis,using BCP. I'm using native format for the BCP because the text inone of the fields can encompass pretty much any ASCII characters, andusing the other options (including the null terminator, stuff like|||, etc) hasn't worked particularly well.So, I'm archiving out a table on a daily basis. I want to script outthe table at the same time; that way, if there are any table changes,an import will still work.How can I do this? I've been digging through google for scripts withno luck. Ideally I'd like a table-creation script, along with CREATEINDEX statements.Anybody have a script handy for this? I know it can be done by usingthe system tables, but I'm hoping to avoid reinventing the wheel.Thanks in advance.Michael
View 2 Replies View RelatedI have a requirement to only rebuild the Clustered Indexes in the table ignoring the non clustered indexes as those are taken care of by the Clustered indexes.
In order to do that, I have taken the records based on the fragmentation %.
But unable to come up with a logic to only consider rebuilding the clustered indexes in the table.
create table #fragmentation
(
FragIndexId BigInt Identity(1,1),
--IDENTITY(int, 1, 1) AS FragIndexId,
DBNAME nvarchar(4000),
TableName nvarchar(4000),
[Code] ....
What is the difference please?

Does anyone have the idea why the Indexes with _WA.....(like _WA_Sys_au_fname_07020F21) gets created.I don't how this index got created. I did not create this Index.
My Question is does the system creates these indexes or something else does this.
Thanks
Chak
Is there a way to tell how many indexes exist for an entire database, all I'm looking is for a count or generating a report list.
any help would be appreciated, thank you
At present I have been assigned to create indexes to retrieve the information fast, from the table. The existing table doesn’t have primary key, foreign key and unique constraints but I found to many default indexes already created by the system. I would like to know how this happened? Please inform how to delete these default indexes. Further, inform me other possible ways for the faster retrieval in SQL sever 7.0, if there are any.
I would appreciate if you send me a step by step explanations for the above problems.
Thanks a lot
I have run into a snag on my development server. Queries that are selecting data based on indexed fields in a where clause are using the wrong indexes. They are arbitrarily using the clustered index which isn't in the select at all and causing big performance problems. I can run the same statements on my production server and it runs based on the proper indexes. I used query execution plans to determine that this was infact the case.
I run DBCC Checkdb everynight and it comes back with no errors. I also rebuild the indexes. We also don't receive any other errors inputting or updating data. This sounds like corruption to me but if it's something else I don't want to spend the night restoring from production if there is another reason.
Has anyone encountered this before? Any ideas?
Appreciate it, K.
Is there any way for me to find out when last indexes have been used so that the one I don't need can be dropped.And also the one's that are of no use at all.
I need this as i am trying to dump all duplicated indexe . i know i can do this in ver 7
thanks
when executed sp_help tablename, I get lot of statistics and indexes like the following. Can anyone please tell me how it is generated automatically. as far i know statistics are generated only for primary keys. Can you please tell me what is clustered , hypothetical and the indexes starting with _WA supposed to be. Also there are lot of duplicate stats. Is it Ok to deletes those.
_WA_Sys_is_platinum_0A9D95DB
_WA_Sys_active_0A9D95DB nonclustered, statistics, auto create located on PRIMARY Active
hind_c_33_15 nonclustered, statistics located on
hind_c_37_1 clustered, hypothetical located
Thanks

Is there a way T-SQL script can find out all indexes built on a set of tables, drop them and periodically ( quarterly as an example ) re-build them ?
Thanks in advance for help.

How do you find out indexes ( with column names info ) on a table ?
Thanks in advance.

I am on SQL 6.5.
I have a question about speed and indexes. I have a static table (no updates except once a year). I want to be able to search data quickly on one column or many columns. I have created nonclustered indexes on each of the columns I search by. Is there anything else I can do to speed up my queries? Unfortunately all the searches involve using the like operator. I have even broken my table down into 2 smaller tables (Table A ~ 3 million rows, Table B 8 million rows).
All suggestions will be appreciated.
Thanks,
Eric
We have to interduce a new naming convention for the indexes currently available in the user databases.
We also have to drop all the old indexes available in about 250 tables and recreate them all acording to the naming convention we are coming up with.
Can any body suggest any idea.
I thank you guys in advance for your considaration.
hi.
there 2 different queries
1
[MYSQL].... where Cat=@CatID and Date=@Date[/MYSQL]
2
[MYSQL]... where Cat=@CatID and Date=@Date and Salesman=@SID[/MYSQL]
these queries are often used.
my question is about indexes.
should I use two different indexes?
index 1 : Cat,Date
index 2 : Cat,Date,Salesman
or only index 2 is enough ?
I need to alphabetize PART of a union all query, and was told that this may be accomplished with an index. I tried joining two views, but it does not work! I have NO experience with indexes and need some help.
Here is my code:
Select id, country from countries where id = 6 union all Select id, country from countries where id <> 6
I want the country with id 6 (USA) to be the default on a drop down list, then all the other countries listed after it in alphabetical order. Can you do this with an index? If so, how do I proceed?
Thanks!

We recently updated some of the databases from MS Access 2000 to SQL Server 2000. In Access we had columns which were set to Indexed No Duplicates, these were not Primary key fields. Is this possible to set some indexes to prevent duplicates in SQL Server without creating performance issues?

Do you have to take the DB offline to create or run indexes in SQL Server 2000??

The table i have stores max 2000 records. Not sure if i neeed a clustered index for this few records. I guess not.
Q2
For the same table as above. How do you create primary keys if there is not unique records.
Do i create a new column? like newColumnID identity? and create a primary key on this new column? Ok even if i create this newcolumn. I don't think it will improve the retrieving speed cause i'm not selecting this column.
Opinions, ideas?
i am running a stored procedure which has got clustered indexes created after creating table and data is inserted into it after creating clustered indexes. The tables which are meant in this sp is temporary tables and how to gain the performance of a query
View 2 Replies View RelatedI've created indexes for the queries below running select getdate() before and after the query to determine the time. I'm curioius as to how sql server determines and decides how and when to use the indexes for the queries and how the run times of these queries compare. I'm also curious to know what kind of difference there would be on the last two queries as the only difference is the values.
For the last two queries I don't think there would be a difference but hoping that someone would know.
Below are my results:
select count(distinct CustomerID)
from Orders
where Status = 5
SELECT getdate()
go
Create Index Orders_Index On Orders(customerID)
go
SELECT getdate()
select sum(TotalDue)
from Orders
where CustomerID = 11212
select getdate()
go
Create Index Orders_Index On Orders(customerID)
go
select getdate()
select count(distinct AccountNumber)
from Orders
where SalesPersonID = 288
select getdate()
go
Create Index Orders_Index On Orders(salespersonID)
go
select getdate()
select count(distinct AccountNumber)
from Orders
where SalesPersonID = 276
select getdate()
go
Create Index Orders_Index On Orders(salespersonID)
go
select getdate()
where can i find a example on how tobuild a script to reindex all my tablesTksDaveP
