Re-Create All Indexes In Database

Jun 17, 2006

First, I'd like some help stablishing if it's a good idea or not what I'm thinking, and second is what would be the easyist way to achive the result.

Background. We have a multicompany ERP system (200GB, 200+ tables). All data tables have a companyid, counter1id, counter2id, fields. Each table has a primary clusterd index on these fields in that order. And also has multiple other indexes that usually include companyid filed first. ( Note we have 10 companies, ids are 1..10, companies 2 and 5 are the most active, inserts, selects ). MY GUESS IS THAT THIS IS VERY BAD HAVING COMPANYID FIRST. AM I CORRECT? LEADS TO AL LOT OF FRAGMENTATION? VERY BAD TO FIND DATA ON THE INDEXES?


I want to re-create all my indexes and have them counter2id, companyid, counter2id. ( counter1id is a counter for each company, and counter2id is a global counter like identity ) GOOD OR BAD IDEA?

Since I have hundreds of indexes what is the correct procedure? I was thinking on scripting the database, then dropping all indexes, then recreate clustered indexes, then recreate other indexes. Do I have to take care of anything else foreing relationships, etc.

Removal Of Selected Indexes / Script Index Create For List Of Indexes

Jul 1, 2014

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?

Create Indexes In SQL 7.0

Mar 13, 2000

When creating the indexes on the table, SQL 7.0 also created some type of system indexes ( ex. _WA_Sys_curr_int_rate_2C88998B nonclustered, statistics, auto create located on PRIMARY, etc. ). I want to know how can I clear up these system indexes.

Does 7.0 Create Permanent Indexes On Its Own??

Oct 29, 1999

Hello,

A few months ago, the company I work for switched to SQL 7.0 from 6.5. All is running fine but recently I noticed that we have a ton of indexes on each table that start like this: _WA_SYS_....0B679CE2 (here are some specific examples: _WA_SYS_PRODUCT_LINE_0B679CE2, _WA_SYS_RMA_DISPOSITION_0B679CE2)

Did SQL 7.0 do this? If so why? What is it trying to do? Why doesn't it use current indexes (clustered and non-clustered)? Why don't they get Fragmented like User defined indexes? I have a lot of questions associated with this if someone can explain it.

Tech Net, MSDN, BOL and other manual resources don't mention anything about it. At least I haven't found anything on it and I have spent some time looking.

Please help if you can.
Troy

SQL 2012 :: Create New Indexes

May 24, 2014

1)When we create Indexes, key columns are the columns that use in where clause and included columns are the columns that can be used in the select list and on join clause column.

2) I am thinking that we have to create new Index, only if we found at least 50 msec time save.

Quicker Way To Create Indexes

Jul 18, 2006

Hi,I have a new job. It needs to drop and re-create (by insert) a tableevery night. The table contains approximately 3,000,000 (and growing)records. The insert is fine, runs in 2 minutes. The problem is thatwhen I create the indexes on the table, it is taking 15-20 minutes.There is one clustered index and 11 non-clustered. This is a lookuptable that takes many different paremeters, so it really needs theindexes for the user interface to run efficiently. However, thedatabase owners aren't keen on a job taking 20 minutes to run everynight.Any ideas?

Auto Create Statistics / Indexes

Sep 1, 2000

Hi everyone,

I know that statistics called _WA_... are created on tables when auto create statistics is set on a database. Is this an indication that queries against the table would perform better if indexes were created on the columns in question? (The tables I'm interested in optimising are used equally for transactional querying and reporting)

Thanks for any replies!

Should I Create Indexes On Views Or Tables

May 22, 2007

I have a pretty large database that has tables that will contain millions of rows of records. I will predominantly be using Views just to select the data. (I will not be performing any updates or inserts). I propose creating indexes on the views. My question is - if I create indexes on my views, do I have to create them on the tables as well? Is it good practice to create indexes on tables by default even if I am not going to be performing select statements directly on my tables but via my indexed views? Any advice is appreciated.

Thanks

Identify Unused Indexes On Database

May 12, 2015

There are too many indexes built on DB. As per the naming convention it seems the indexes are built as per the suggestions provided from execution plan. I presume most of the indexes are used only once in a month for the reports but are hampering the performance of daily running queries. These are also occupying a lot of space.

To confirm on this I have used the below query to know & identify the unused indexes. I have recorded the counters before and after the huge operations and I observed NO CHANGE in any of the values.

What the below values exactly indicate and when do they change? Is it good to delete the indexes having low USER_SEEKS, USER_SCANS, USER_LOOKUPS?

Query:
SELECT OBJECT_NAME(S.[OBJECT_ID]) AS [OBJECT NAME],
I.[NAME] AS [INDEX NAME],
USER_SEEKS,
USER_SCANS,
USER_LOOKUPS,

Rebuilding Large Database Tables And Indexes

Jul 7, 2015

I have come across a database system which isn't designed to work optimally. It is fairly large (~400GB) and performance of loading and querying is degrading (improper data types, fragmented indexes, non unique clustering key and other problems). So, I have quite a task in front of me, but I am up for the challenge. I figure this is not a unique situation, many of us would have come across this before. I have done this before too, but only for smaller databases, some of the operations here I expect to take a couple of hours or more to complete (depending on load/infrastructure speed etc, I know).

My plan is thus:

+ Take a full backup of the database
+ Set the recovery model of the DB to simple
+ Drop non clustered indexes
+ Drop clustered indexes
+ Remove PKs (wrong data types, too large!)
+ Narrow data types (add new column, update column in batches to old value, rename new column to old column)
+ Add PKs, which will create clustered indexes automatically based on PK ID
+ Create non clustered indexes
+ Run a SHRINKDB (normal operations I would never do this, but this is a special case, ensure log file is truncated to a logical size especially after all those table modifications...)
+ Set the recovery model of the DB to Full
+ Ensure everything works OK or better

Can CREATE DATABASE Or CREATE TABLE Be Wrapped In Transactions?

Jul 20, 2005

I have some code that dynamically creates a database (name is @FullName) andthen creates a table within that database. Is it possible to wrap thesethings into a transaction such that if any one of the following fails, thedatabase "creation" is rolledback. Otherwise, I would try deleting on errordetection, but it could get messy.IF @Error = 0BEGINSET @ExecString = 'CREATE DATABASE ' + @FullNameEXEC sp_executesql @ExecStringSET @Error = @@ErrorENDIF @Error = 0BEGINSET @ExecString = 'CREATE TABLE ' + @FullName + '.[dbo].[Image] ( [ID][int] IDENTITY (1, 1) NOT NULL, [Blob] [image] NULL , [DateAdded] [datetime]NULL ) ON [PRIMARY] TEXTIMAGE_ON [PRIMARY]'EXEC sp_executesql @ExecStringSET @Error = @@ErrorENDIF @Error = 0BEGINSET @ExecString = 'ALTER TABLE ' + @FullName + '.[dbo].[Image] WITHNOCHECK ADD CONSTRAINT [PK_Image] PRIMARY KEY CLUSTERED ( [ID] ) ON[PRIMARY]'EXEC sp_executesql @ExecStringSET @Error = @@ErrorEND

Create Script To Create/Refresh Identical Database

I've tried searching for anything but haven't had any luck as of yet. I guess I don't even know where to start or what to look for.

Any help would be appreciated. Thanks!

DEBATE: Moving Heavily Used Database Or Breaking-off Indexes

Feb 20, 2002

Scenario:


We run a multiple database environment, with two of the databases receiving most of the user activity. (both write and read). These databases are roughly 25gb each and receive roughly the same amount of activity. Currently both of the .mdf files sit on the same drive shelf. Their log files are located on a separate drive shelf.

Debate: We have an extra fiber channel shelf available for us to use. We are not having too many problems related to performance, but we are always seeking for different ways to increase application/server performance. The debate centers on what to do with the extra shelf. There are two different suggestions on how best to use the shelf. They are:

1)Separate the .mdf files for two most utilized databases. This would separate the databases and the I/O associated with each across two different shelves

2)Break off the indexes for all 5 databases on to the extra shelf. This would leave all the .mdf files on the same shelf, but it would move the I/O associated with the indexes to a different shelf.

Can anyone provide the pros and cons of either suggestion?
I would like to see arguements for either side.

DB Engine :: Removing Unused NC Indexes From Subscriber Database

Nov 13, 2015

We have transaction replication set up on one of our servers whose replicated DB is used for reporting purpose:

Now, the replicated database "D" of size 350 GB has mainly grown huge as compared to Published DB (200 GB) because of the index sizes at subscribed DB. Therefore:

I have found that Database D has one table of data size 15 GB, with rows 8349533 and index size 28 GB the biggest in the database. And adding have total of 109 Non clustered indexes:

On using SP_blitzindex i have found approx 50 NC indexes unused with below usage:

Reads: 0 Writes:273,243 and total size of indexes being 18 GB

Last User Seek
Last User Scan

Last User Lookup all '0' 
0 singleton lookups; 0 scans/seeks; 0 deletes; 0 updates; 
except for few 3 or 4 where updates are more than 4000.

Is this sufficient enough to delete all the above 49 unused NC indexes? And Can i create Missing index on Subscriber database?
