SQL 2012 :: Check Size Of Database After Implementing Data Compression Across All Tables
Dec 4, 2014I found it pretty interesting. I checked the size of a database, before implementing database compression across all the user tables in a database. And Post implementation of compression too I checked the size of the database.
I did not find any difference. But if I expand the table and check propetires->storage and I can see that PAGE compression is implemented across all the tables, but no compaction in the size of the db. It still remains the same.

Feb 11, 2015I have huge table, often I need to query the table on the whole; ie., data may required at any part of the table. So I think of to compress the table with the aim of reducing I/O.
1. is that really suitable for this requirement? If So which compression is good (Row or page )?
2. Or is there any other alternate to reduce the I/O (Except Indexing)?
3. Pros and cons ?
SQL 2012 :: SSMS Object Explorer Lock Timeout When Running Compression Script
Jan 21, 2015ALTER TABLE [dbo].[TableNameExample] REBUILD PARTITION = ALL
WITH (DATA_COMPRESSION = PAGE)
The table is 110 GB, so will take time to compress. But it is one table in a database with 60 tables. Why would executing this statement, cause lock timeout on Object Explorer in SQL Server Management Studio? Users cannot drill down objects in this database without getting lock timeout.
When I cancel the compression script, users of SSMS can access objects in this database again from the GUI. Why does compressing a specific table affect access to all tables metadata? I cannot find anything on the internet but I am sure this has happened to other people.

Apr 14, 2015I got into confusion while working on DB Growth report for 2012 databases which has compression on.I am analyzing the DB Growth based on MSDB..dbo.backupset table which stores the backup information.
But here it gets tricky, In Previous versions we use "backup_size" column to get actual backup size and estimate the db growth based on the previous all backup file info. But now since compression is on in 2012 the "backup_size" colmuns gives a compressed file size(If i am right) so how do you know the actual backup size to estimate the db growth over a period of time??
SQL Server 2012 :: Data Grouping On 2 Levels But Only Returning Conditional Data
May 7, 2014I think I am definitely thrashing and am not getting anywhere on something I think should be pretty simple to accomplish: I need to pull the total amounts for compartments with different products which are under the same manifest and the same document number conditionally based on if the document types are "Starting" or "Ending" but the values come from the "Adjust" records.
So here is the DDL, sample data, and the ideal return rows
CREATE TABLE #InvLogData
(
Id BIGINT, --is actually an identity column
Manifest_Id BIGINT,
Doc_Num BIGINT,
Doc_Type CHAR(1), -- S = Starting, E = Ending, A = Adjust
Compart_Id TINYINT,
[Code] ....
I have tried a combination of the below statements but I keep coming back to not being able to actually grab the correct rows.
SELECT DISTINCT(column X)
FROM #InvLogData
GROUP BY X
HAVING COUNT(DISTINCT X) > 1
One further minor problem: I need to make this a set-based solution. This table grows by a couple hundred thousand rows a week, a co-worker suggested using a <shudder/> cursor to do the work but it would never be performant.

Nov 11, 2014I have 2 tables in my database.
one is Race table and 2nd one is Age Range.
I want to write a query where I can see all races and age range as column.
TblRace

Compression
Apr 2, 2004Hello,
I have been wanting to compress my database. I am not really sure how this is done. I was looking on Enterprise Mangr. and if you right click on the db and go to all tasks, there is an option to shrink database. Is this the way you would compress your database, or are there other ways of doing this?
Thanks for all the help.

Message Compression
Sep 15, 2005We have run some tests on our application. Average message is about 2.5 MB. Messages are send once every 30 minutes. This is 3.5 Gb per month for one site. Now we already have three sites that will be sending this messages. This will be VERY high load on the WAN channel, and will cost us a LOT of money .

View 3 Replies View RelatedDatabase Backups && Compression
Jun 19, 2007Hi All
I have a database which is 72GB, which is backed up every night as part of the maintenance plan. I have plenty of storage space, and the server that runs the database is fairly powerful (quad-processor 3.2ghz, 64bit, 48GB RAM) and is part of an active-passive cluster. The database backup is also copied to a SAN location.
My issue is with the size of the backup file. As part of the Disaster Recovery plan, I need to copy this database backup file accross the network to a remote site, so that in the event of a disaster at the site, business can continue at the remote site after restoring the database backup file. However, my database backup file is so big that I cannot copy it accross the network in time for the next morning. I have tried using WinRar and have managed to achieve a file about 20% of its original size, but it takes 2 hours to produce this file.
Is there any recommended reeading for this type of issue? Log shipping / mirroring has been investigated and will be part of the DR model but the 'powers that be' insist on having a full copy performed to the remote site.
Any suggestions? Thanks in advance guys n gals :-)
Use Backup Compression On Few Servers
Jul 26, 2015I am wanting to use backup compression on a few sql servers (2008R2 and 2012). I have never touched compression before and always just gone with the default.I use Ola Hallengren's scripts to do the backups which, if not specifically specified, will use the server default.Backups (FULL and LOG) have been happening successfully on these servers for years.SQL won't care that the previous backup in the set was uncompressed or that the hourly transaction log backups previously taken were uncompressed?Restore statements (T-SQL) will be identical?From everything I am reading it is simply a case of setting the configuration and acting like nothing changed but I just wanted to be 100% certain.1 of the servers is a SharePoint backend.All of the backup files from all servers are picked up by Commvault backup system.
View 4 Replies View RelatedPrint Compression When Deployed
Dec 14, 2006I have a report being utilized for return address labels, conforming to Avery 5167. I have tried designing both as a table and as data in rectangles. Since these are return labels their is only one instance of data replicated for all textboxes, therefore the columns are of consistant length.
The report has seven columns of precise measurement, the data filled colums are set as 1.75in, 0.25in, and between the data columns are blank columns set to .3125in, 0.25in. I have also tried to fill data into the blank colums and set the font color to white. All report margins are set to 0in and the table location is 0.04167in, 0.125in. all textboxes have the properties for increase/decrease to accomadate turned off.
The biggest issue I am having is in printing from the deployed report versus printing while designing. I have adjusted for the glitch in margins for RS2005 and have printed succussfully prior to deployment to adhere to the specific measures for the label, report margins and textbox height and width and blank column spacing.
However, after deploying the report the data spacing seems to be compressed when printed. I am not getting the same measure between data fields as I had when designing the report. The entire printout seems to be slightly compressed.
When printed from design colums 1,3,5, and 7 start respectively at .3125in,2.375in,4.3756in,6.4375in from the edge of the page.
When printed fromt he deployed report columns 1,3,5 and7 start respectively at .3125in,2.3125in,4.28125in,6.28125in.
The progression of compressed measure seems to increase from left to right inthat by the time the report is printed via the deployed report the "Tab" area is a difference of .15625in which when printing for very precise template format this creates a problem. As well as a headache when one thinks the report is correct before deployment.
Transaction Log Shipping Over WAN With Compression
Jan 18, 2006Hi guys,
I have a server in a datacenter (SQL 2005 ent) that collects large quantities of data from our visitors. I need to set up a secondary database in our office (different geographic location) that will server 2 purposes, 1, a backup of the database and 2, allow us to perform complex queries on the data.
There is no updating of the data on the secondary server so no changes need to go back to the primary server. A database in standby mode is fine and users on the secondary server can be disconnected when it's being updated.
I have transaction log shipping working well in a staging environment (LAN). My first question is is there any reason why transaction log shipping would not work over a WAN with a VPN connection?
And my second question is can I compress the trn files for transport over the WAN. If I manually compress the files with winzip they compress by 98%. That translates into a huge saving when I am leasing a line to transport these files.
Thanks in advance
Stephen
Delta Compression Of Query Results
Feb 14, 2007Suppose a database server and client are separated by a low bandwidthlink such as DSL, and the client repeatedly issues a query for, say, acurrent product list.Suppose the product list is large, but only a handful of entries havetypically changed between queries. It would be nice if only the changesfrom last query to current one could be sent, saving bandwidth.Is there any way to do this?Thanks,--"Always look on the bright side of life."To reply by email, replace no.spam with my last name.

Sep 28, 2007We have a number of large binary xml messages. I would like to compress the XML before converting to VARBINARY as much as possible. What is the recommended way to handle this if the conversions are happening in TSQL? I will also need to be able to decompress in .NET code, so I'm wondering if the best way is to just use CLR Integration for the marshaling routines, rather than building the marshaled structure in SQL. Any suggestions on reducing the XML payload size for extremely large messages?

SQL Server 2012 :: How To Insert Data Into Table From Linked Server
Nov 19, 2013I wonder if it possible to move data from tables on a linked server to a "normal database"?
Name linked server: Covas
Name table on linked server: tblCountries
Name field: cntCountryName
Name "normal" database: CovasCopy
Name "normal" table: Countries (or dbo.Countries)
Name "normal" field: Country
This is just a test setup. I figure that if I get this working the rest will be easier.
My current query:
select * from openquery(COVAS,'
INSERT INTO CovasCopy.dbo.Countries(Country)
SELECT cntCountryName FROM db_covas.tblCountries;')
