Using lot intermediate table in SP, at end of the SP, those table are getting truncating.but those pages are still unallocated and unused , How to unallocated the space and add to OS drive.
Because of above scenario, we are wasting lot of space. i am seeing lot of unallocated space.
say if I am doing an simple insert (50 million records) with union all into a table.... when i check it while the query is running I see some records inserted.... however, at the end i have no data... table gets truncated. Is it so because I was out of space (I checked the drives and seems like data drive is running out of space).
Thanks for ur help.
I have a database that has grown larger than I had expected. I thinkthere is one table that is at the root of the problem. The table isdefined as follows:CREATE TABLE [dbo].[UserAudit] ([UserAudit_id] [int] IDENTITY (1, 1) NOT NULL ,[UserAuditAction_id] [int] NOT NULL ,[Dataset_id] [int] NOT NULL ,[UserName] [char] (64) NOT NULL ,[TableName] [char] (64) NOT NULL ,[Detail] [varchar] (4000) NOT NULL ,[DateRecorded] [smalldatetime] NOT NULL ,[Dsc] [char] (256) NULL)There are 14919 records in this table. When I do the calculations iapproximate that space used by this table should be in the region of10mb (4+4+4+64+64+290(average length of Detail column)+4+256) * 14919.When I execute "sp_spaceused 'UserAudit'" i see that 119MB are beingused by this table.name rows reserved data index_size unusedUserAudit 14919 119808 KB 119352 KB 400 KB 56 KBEven if I use 4000 for the Detail column in my calculations I stillcome up with about only 64mb.Any ideas on whats going on here?Thanks in advance.

View 6 Replies View RelatedI'm trying to determine how much space some tables use (SQL2000), and I found 2 suggestions posted earlier, but can't get them to work for me.
The first was
"Right click on the DB in Enterprise Manager, select view then taskpad."
When I try that, I get some of the tables displayed with the info I want, but I can't see them all and can't scroll down beyond the first 22 tables in the database.
The second suggestion:
exec sp_msforeachtable @command1="print '?'",@command2="sp_spaceused '?'"
It says "command copleted successfully, but where does the output to this go ?? Is there something other than "print" I should use ?

Enterprise Edition SQL2k sp3a on Win2k3 Enterprise Edition server.
Using BCP to load ~4 million records.
Largest record width is ~350 bytes.
When finished i have over 6 million pages reserved and only about 800 thousand actually used.
Which puts me 'round about 3 rows per page and WAY too much empty space.
YIKES!
Any thoughts as to why this is happening?
Or insight into how BCP handles page allocations that may be different than the typical extent based page allocations for table data?
Thanks!
I have a stored proc that processes large amounts of data. I have used temp tables in this stored proc. After I drop these temp tables, it doesn't release the disc space and my hard drive runs out of space before the process ends. When I stop the sql service and restarts it, it releases the disc space. How can I force the release of disc space inside of my stored procedure?
View 6 Replies View RelatedI'm trying to figure out how to reclaim unused space in a huge table (tbl) after setting one of the text columns to be the empty string. Other tables have foreign key columns associated with tbl.
After doing something like this,
update tbl set col = ''
the table doesn't automatically reclaim that space. If I do a direct insert into a new table like this,
insert into tbl2 (cola, colb, colc) select * from tbl
the new table is smaller as expected (about half the size in my case). Any ideas?

The default behaviour for pressing SHIFT + SPACE when editing text inside a cell in the Table Editor view in Microsoft SQL Server Management Studio Express is to change focus to select all cells comprising the current row. This behaviour lends itself to the default behaviour for pressing SHIFT + {LEFT | RIGHT | UP | DOWN } in changing the focus to select adjacent cells.
However, I find this is quite annoying as the SHIFT + SPACE combination is quite a common miss-type when entering text in UpperCaps or when entering text with spaces while holding the SHIFT key.
Anyone else have this gripe with MSSMSE? Anyone know how to disable this behaviour?

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.

My client's website database is hosted by a third party. I need to alter one of the column definitions for the largest table in the database. Unfortunately, the transaction log fills up if I try to alter the table. I've done all the usual stuff like truncating the log, etc., but the simple fact is that the operation requires more log space than we have available. Therefore, we need to purchase additional disk space for the database.
What I'm looking for is a way to roughly estimate how much log space will be required to alter this table so that we purchase enough but not too much additional space. The table has an identity primary key and 4 other single column indexes: one int, one datetime and two varchar(30) columns.
Any suggestions? Thanks in advance.
In our SQL Server database we will have a table that will be populated with about 2000 recordsper day. That is 2000 records per day for 5 days per week. Currently the computer we are using has about 50 gigabytesof available hard drive space on it. We are concerned that maybe we will need a bigger hard drive,based solely on the number of records entered into this table per day. The problem is I don'tknow how to calculate how much hard drive space we need. I think I read that using varchar,sql server 2005 really optimizes a database. Here is a typical example of data in ourdatabase. I put dots on three lines between the first and last sample record to justillustrate that there are many records in between.
Basically we only need 8 months of data at a time in the table and then we can purgerecords older than 8 months.Can someone help me approximate how much hard drive space I might need for 8 months of data,given the following sample record in the database?
Sample: -->34.5 4.08 10.6 .0012
Sample Table in my DB just for illustration:
(PPsquare inch) (Diameter) (Weight gm) (coeffOfSatFriction)
34.5 4.08 10.6 .0012...21.7 3.54 6.22 .019
The sp_spaceused proc seems to have been removed in 7.0?

Hey guys,
I have a table which has 6 text columns (tblA).. I no longer require 1 of those text columns and want to reclaim the space that it is currently taking up..
Is the only way to BCP out all the data (except the 1 column i no longer require) drop the column and BCP the data back into the table?
I hv dropped the useless columns for a table but the table size is remain unchanged by executing sp_spaceused. pls advise how to release table spaces.
thx
currently stuck with an issue where I need to reclaim the unused table space in SQL server.
ISSUE: Due to database size issue we have moved all the images from database to filesystem and want to reclaim the unused space now....I have tried shrinking the database and rebuild the indexes but didn't see any difference in the table or database size.
Similarly I have identified many Non clustered indexes on big transactional tables(~ 4 million records) that where not used since GO live 1 year back, so I wanted to drop these indexes to cut down the performance and maintenance overhead , so my question is will dropping these indexes reduces the database size?
best method to my issue regarding unused space. SQL SERVER 2014 BI EDITTION..I have a table that showed 62% Data, 7% unallocated, and 29% unused space.I ran the ALTER TABLE <table name> REBUILD, which changed it to 32% data and 67% unused.What I do with this table monthly and what I believe is causing this unused space issue is this:Every 1st of the month I get a csv file that holds around 3.2 million rows/15 columns of data. About 3 gbs every time.It's 13 months of data. I remove the last 12 months from the current table and import the new 13 month data.I do this twice a month and have no choice because the data is constantly updated and why we get it twice a month.So I am deleting around 6 gbs of data a month as well as adding around 6 gbs of data a month.
I believe this is why I end up with so much unused space, but just found the REBUILD command, which worked but now a small hit on performance and have too much space in the current table. I have read several times that shrinking the file is no good, but what other way to get rid of the extra space in this table? Also, the table doesn't have any indexes or primary key because of duplicates.
Edit 2007-8-9:
Added code to show database file sizes. Not really closely related to tables sizes, but a lot of the people who need this want to know why their database it so large, so it may help to know which files, especially the logs, are so large, and if the files have empty space in them.

As I understood, if SPARSE is used on a column, which have many NULL marks, then the storage could be efficently used (we need less spaces to save NULL marks, hence a table which has many NULL marks with SPARSE property needs less storage than the same table, but without SPARSE. I created two table as follow:
/******* Table with Sparse ******/CREATE TABLE Sprstb(
unsprsid INT IDENTITY(1,1) NOT NULL,
Firstname varchar(20) NOT NULL,
Lastname varchar(20) NOT NULL,
Tel int NOT NULL,
adress nvarchar(60) SPARSE NULL)/***** Table without Sparse*******/CREATE TABLE Unsprstb(unsprsid INT IDENTITY(1,1) NOT NULL,Firstname varchar(20) NOT NULL,
Lastname varchar(20) NOT NULL,
Tel int NOT NULL,
address nvarchar(60) NULL)
I have populated the Sprstb with 5 Milion records. It needs 509,961 MB storage. Then I have copied this table into Unsprstb
SET IDENTITY_INSERT [dbo].[Unsprstb] ON
Insert [dbo].[Unsprstb](unsprsid,Firstname,Lastname,Tel,adress)
SELECT unsprsid,Firstname,Lastname,Tel, adress FROM [dbo].[Sprstb]
SET IDENTITY_INSERT [dbo].[Unsprstb] OFF
The Unssprstb need only  466,031MB !
That means the Table with SPARSE column need more storage, Why?Â
By the way, in table Sprstb column address has  1666198  Null mark (from 5000000)
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 12 Replies View RelatedI have many large tables with millions of records in a SQL Server database. They all use an Identity column which is the clustered index. We haven't been deleting any records until recently because disk space is now becoming a problem.
Assuming I delete a lot of old records, I'm thinking that the freed up space in the data pages won't be reused. New records will be added at the end of the table because of the Identity column being the clustered index. So the table will keep getting bigger even though there is lots of free space.
Assuming I'm right, then how do I recapture this unused space? Is an alter table rebuild the best way? Or rebuilding the clustered index?
Hi All ..
I have 2 disk drive
C and D
The SQL Server data and log files are stored in D: drive
I have only 575 MB free spaces in C: drive
I have a Sql data base name StoresDB and there is a table name CustTBL
There are almost 6555500 rows in that table
My issues are whenever I am querying the CustTbl from Query Analyzer
(Select * from CustTbl)
The C: space decreased to 40 kb
And the same time,I am not getting all the rows in the query result
In Query analyzer Message Tab it is showing (6555151 row(s) affected)
But In the Grid Tab it is showing Grid#1 :6318847 rows or sometime less rows....
What is the reason to for these two issues?
I have updated the index and statistics for CustTbl TABLE but not got any changes
..
When I closed the query window the C: drive again showing 575 MB free space
Hi all,
Report:
-For instance 2 small tables (eg. width 10cm = 3 inch?)
-And one wide table (eg. width 30cm = 10 inch?)
All separated by "insert pagebreak after table".
Problem:
When rendered, the pages with the small tables on have a lot of white blank space at the right of the table. This is probably caused by the big table on page 3.
This report is distributed by email in Excell format. So on sheet 1 and 2 there are a lot of white cells on the right of the tables. When trying to print, they just want to use the "landscape" option and the "fit to page" option. Because of the empty white cells, the fit to page option reduces the first 2 tables to a very small table which covers only 50 % of the page width. The other 50 % is reserved for the empty cells.
Off course, I know that deleting the empty cells offers a solutions, but it would be a lot more handier if there were no empty cells in the first place.
Anybody with a solution?
