hi all
i am under impression that indexes also stored seperately from data and need extra space . when we check in EM Table Info, size over there is just data size or sum of data and indexes. if it is just for data then is there is any space used to store indexes and that space is counted in space used by data base or else where.............. please clear my confusion.............. i am quite new in administartion of SQL Server
Hi Folks:
This seems like a pretty straightforward question, but since I've been trying to find this in BOL and not having any luck, I thought I'd ask some folks more experienced than I.
How much room do I need on a SQL box to restore a 6.45 gig database? (it's
going from a huge machine to a backup tape, then from the backup tape to a
much smaller machine for testing an app, and we're trying to find out what we need to do to make it all work out.)
I'm assuming that I would need significantly more than the 6 gigs of the db for the work of actually doing the restore, but can't find out how much more...
Any ideas would be most appreciated.
Many thanks in advance,
Tom
Quick question- how much disk space is required on the subscriber to initialize a subscription (transactional replication) – does it have to copy the snapshot files (e.g. the bcp files etc) from the distributor, and then initialize the subscriber from this, or does it do this over the network?
Does it differ depending on whether it is push or pull?
Say I have a 10 GB snapshot on the distributor with a push subscription to the subscriber. Do I need 20 GB free on the subscriber? E.g. 10 GB to receive the snapshot files + 10 GB for the subscriber DB? Or just 10 GB for the subscriber DB which is initialized from the snapshot files over the network?
Thanks in advance for any help with this.
Hi ,
if we have two file group in a particular sql server 2000 database (c and d drive), and in that database suppose one particular table (location c drive) is growing very fast, i want to move it to D: drive file group. so how we can do it.
Thanks

We have a table with 48 million rows. The table should only be approximately
28 bytes long for each row. This table is clustered primary key consisting of
an integer key and a calculated float value. We have found that the size of the table
is doubled before statistics are gathered. There is a foreign key that references the
primary on another table. There are no other indexes. Sp_spaceused shows the
size changes in the data portion. I had worked on another DBMS system that
had no benefit on collecting statistics on a clustered value. Is this not correct for
SQL Server? Does anyone have an explaination for the size change?
This database is running on SQL sever 6.5.
We are running an home-created stored procedure that includes several rounds of dropping and recreating indexes in a few tables, i.e., after dropping indexes, the tables are truncated, then a lot of records will be inserted into the table, and the indexes are recreated.
we are getting the following error in turns:
1. ODBC error: Microsoft] ODBC SQL Server Driver] SQL Server]Can't
allocate space for object '-841' in database 'tempdb' because the
'system' segment is full. If you ran out of space in Syslogs,
dump the transaction log. Otherwise, use ALTER DATABASE...
We then used EM to expand the tempdb, when reran the procedure, we got the following message:
2. ODBC error: Microsoft] ODBC SQL Server Driver] SQL Server] Cannot
drop the index 'dbo.ItemBalamce_CCB_Id',because it doesn't exist in the
system catalogs.
However, when I check the mentioned index, it is certainly there.
How could this happen?
After several rounds of running theis procedure, these two error messages appeared to occur alternatively.
If you have an answer or suggestion, please let me know ASAP.
Many thanks.
I'm upgrading to SQL 2012 from 2008R2, while doing so i will be rebuilding all the indexes on all the database. In my previous environment while doing so, i got space related error in primary filegroup for insufficient space in the primary filegroup. Is there any rule of thumb about how much space is required by index rebuild command for each database, or is there a safe threshold for free space in the database?

Is it possible to reclaim space after rebuilding indexes(shrinking is not an option).
View 9 Replies View RelatedI was trying to find out how much space is available in a 2000 db for allocation to tables and indexes. I am trying to find the amount of space that has to be used-up before another allocation is automatically made to the database. I looked at sp_spaceused but BOL is rather sketchy at defining what the numbers it returns really mean. Is the "unallocated space" the value I am looking for?
Thanks,

Hi all,
When I am rebuilding the indexes on the tables, I am getting lot of free space( unallocated) on the database.
Before rebuilding the indexes , the size of the database = 385 Gb
After rebuilding the indexes, the size jumps to = 572 Gb (i.e.) This means 187 Gb of unallocated space .
The Command use to rebuild indexes is:
USE [databasename]
GO
ALTER INDEX [PK_index] ON [dbo].[tablename] REBUILD WITH
( PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON, SORT_IN_TEMPDB = ON, ONLINE = OFF )
GO
So, every time we rebuild indexes, we have to shrink the database
(or)
Is there anything else ,I should be doing.
Thanks.
Normally we use rebuild, reorganize indexes when it is required, I used a SQL job using maintenance plan to run daily and rebuild, reorganize indexes and update statistics but I do not know if it runs either they are required or not. Should this plan automatically execute the build upon required indexes to be rebuild or it fires either they are required to be executed or not.

View 1 Replies View RelatedDear all,
In my current database design, there is one table (PState) which has a Primary Key (int) and a few other fields.
During development, a pattern started to arise; for certain rows in PState, I wanted to specify an additional set of columns (over 10 of them with quite large lengths) for each row in PState. However, as these additional columns would only be required in approximately 20% of the rows of PState, there would be plenty of NULL values in PState if I would make this table wider than necessary. So, I decided to create a separate table with those optional columns (PStateWFI). In order to attach these additional columns in PStateWFI to PState in the cases they were needed, I would obviously have to create a Foreign Key constraint on the Primary Key of PStateWFI so that these optional rows would know which row in PState they would belong to.
However, the problem with this approach is that one could define multiple rows in PStateWFI referring to the same row in PState, which would not make sense. Thus, a UNIQUE index constraint added to the constrained ID column in PStateWFI would make sense to ensure that there could only be one set of optional columns added to each row in PState. But now, when adding the UNIQUE index, the FK constraint started to appear as a bidirectional key link in the Diagram; hence, new entries in PState would have to meet a FK constraint based on PStateWFI, which was not intended.
Hence, I had to create a quite awkward design to enforce the constraints:
1. The PState table has a Primary Key (PState.ParticleID, int, Identity Specification: Yes)
2. The PStateWFI table has a Primary Key (PstateWFIID, int, Identity Specification: Yes)
3. PStateWFI has field "PStateID" which has a FK constraint to PState.ParticleID (which is a one-way constraint operating in the correct way and does not constrain insertions in PState)
4. PStateWFI has an additional column ParticleIDIndex which has a UNIQUE Index attached to it.
5. There is a check constraint on PStateWFI enforcing PStateWFI.ParticleIDIndex = PStateWFI.ParticleID.
Although this structure does the job, it makes it necessary to add a redundant column in PStateWFI by duplicating the PStateWFI.ParticleID into PStateWFI.ParticleIDIndex, since I can't create a UNIQUE index on PStateWFI.ParticleID without constraining the PState table as well. So, insertions into this table would have to insert the same value into two columns. Not a big deal, but appears slightly ugly.
Basically I'd hope someone could explain why a bidirectional FK constraint has to be enforced on the primary key table in a relationship when the constrained column in the primary key table has a UNIQUE index attached on it. I have a few other cases where the above approach would benefit from a more clear structure.
Thanks in advance for any advice.
I've been asked to look at using Clustered Columnstore indexes for one of my tables. The table contains about 5 million records with about 50 columns. The max field size is a NVarchar(MAX) with max field length currently of about 4k characters. It's only about a gigabyte's worth of data. The table is about 50% R/W operations. Currently, we have multiple indexes with no clustered index due to some performance issues that happened in the past. I've been attempting to determine if it's even really worth it to switch over. I feel that the table is still fairly small with minimal columns and don't believe there will be any noticeable improvement over traditional indexing.
View 3 Replies View RelatedI had an existing table with lots of indexes.
As a test (fro speed) - I added a non clustered column-store index.
When I run test queries it always ignores my new column-store index. Why?
Should I remove the old indexes, leaving just the column store?

View 3 Replies View RelatedI'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?

I am generating a Report from Sql Data Source in Sql Server 2005 and viewing the Report in Report viewer control of Visual Studio 2005.
The data in the Data Source contains string with multiple spaces (for example €œ Test String €œ) but when they get rendered in Report viewer control, multiple spaces gets converted to single space €? Test String €œ.
I tried following solutions
1) Replacing spaces with €œ €?
2) Inserting <pre> tag before the string and </pre> tag after the string (Also tried <Pre> instead of <pre>)
But in all the cases result is same. The Report Viewer control is showing €œ €? instead of space and €œ<Pre>€? tag instead of preserving spaces.
Please provide me a solution so that spaces can be preserved in Report Viewer.

Hi.. I was doing a good maintenance on my DB and my trans log LDF keep growing until 30GB but my DB data file MDF is only 2GB. I found the two following method to reduce my log size.
Method 1: I used veritas to backup log file with truncate
Method 2: I used the shrink database option in Enterprises manager to shrink it (file chosen=log , use default option)
After doing that, I found my LDF log file is still about the same size=27GB but when I see clearly, from the shrink database windows, the log spaced used reduced to only 100MB, the allocation log space is still 27GB. Why? How to make the LDF smaller to be the around the same size as the space used 100MB?
This is driving me bananas. Can't find any info on this anywhere....SQL 2000 seems to replace double space with a single space when I seta varchar field to " " (2spaces), it only stores " " (1space). Whyon earth would microsoft do this? If I save 2 spaces - I WANT TO SEE2 SPACES!!!!Can anyone help? Is this a database setting? Is this due to usingvarchar?Any help appreciated.Colin Hale
View 2 Replies View RelatedHello,
Somebody know how to reduce the space allocated for the transaction log space for my SQL_DB ?
3700 MB allocated but only 100 MB used and 3600 MB are free !
Transaction log properties :
Automatically grow file are filled
file growth by percent = 5%
maximum file size - restrict filegrowth = 3700 MB (we can't reduce it !)
Thank you for your precious help !

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 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?
