Hi all,
I found a database file and a log file over 2G on mssql 2000 server. Actually, they only need around 200M. I try to backup, truncate the database in order make the size smaller. But the size cannot be smaller. How can I do it?

HiI have a backup device file ... ".bck" whick has grown pretty large.Is there any way I can reduce its size ?ThanksDavid Greenberg
View 4 Replies View RelatedI have a database in 2 GB .mdf and a 1 GB ldf. The backup is much
smaller. I need to copy this database to another server which does
not have that much free space. Can this be restored to a smaller
.mdf and .ldf? How?
Thanks.

I have a weird problem.
We are importing a very small subset of a big desktop database into a CE database on a mobile device for an occasionally connected application. The idea is that the mobile device can use this CE database as a fall back database in case we are not connected.
The database is a very simple list of barcodes.
Basically a single field as primary key
EAN13 bigint
When we import 200K rows (yes we have quite a lot of them). The database is 7MB!!!! A bit big I would say since 8 bytes times 200.000 is only 1.5 MB. Where does the extra space come from?
Yes I did compact the database after the import
Hi all:I restored one backup database (7.9 GB mdf) on two diffrent servers. Ishrunk them by clicking "Move pages to beginning of file beforeshrinking".After shrinking, one mdf file is 6.7 GB, and the other is 4.2GB. Ishunk again and again:1. the 6.7GB become 5.9GB, 5.2GB, 4.7GB and 4.2Gb (four times)2. the 4.2Gb become 4.0GB (just one more time)It is wired, I am wondering the mdf will be smaller and smaller if Icontinue to shrink them? What is the reason?ThanksWJ

I have asked this question on 3 forums now and never get an answer, I don't know what is so hard about this question but I will try it here.
I am using SHA512 in C# to convert a password and its salt to hashed. I need to store the password hash and the salt hash in the database in two fields. I was told to use binary field to store the hash data and that the output of SHA512 would ALWAYS be the same no matter how long the password is.
I modified this hash example to use only SHA512 and to work with byte array instead of plain text.
All I need to know now is what size I need to make my binary field to hold this password that is hashed.
http://www.obviex.com/samples/Code.aspx?Source=HashCS&Title=Hashing%20Data&Lang=C%23
Say I have a password which is 30 characters max, and a salt which is 16 characters max. The password and the hash are stored in seperate fields in the same table. They are both hashed using SHA512 and are both being stored as byte arrays in C#, what size to I need to make the binary data type in order to hold the password, and to hold the salt.
Thanks!
I am calling my report logo image via http: url
the moment the image is loaded to image control, it is changing its height and width.
how can i make it fixed and the image to be resized appropriately to fit the image control.
Thank you very much, for the help.
is there any way i can make a field in a table accomodate more than 1023 charcters? i used the 'varchar' datatype and used a length of 2500, but still, I can't fill up a field with more than 1023 characters. Is there any way to change it?
Also, is there any way to used a symbol or special character in a field? Can SQL server identify such a character? like the alpha or beta symbol...
Thank you...

Hi,
i use this script that show me the size of each table and do the sum of all the table size.
SELECT
X.[name],
REPLACE(CONVERT(varchar, CONVERT(money, X.[rows]), 1), '.00', '') AS [rows],
REPLACE(CONVERT(varchar, CONVERT(money, X.[reserved]), 1), '.00', '') AS [reserved],
REPLACE(CONVERT(varchar, CONVERT(money, X.[data]), 1), '.00', '') AS [data],
REPLACE(CONVERT(varchar, CONVERT(money, X.[index_size]), 1), '.00', '') AS [index_size],
REPLACE(CONVERT(varchar, CONVERT(money, X.[unused]), 1), '.00', '') AS [unused]
FROM
(SELECT
CAST(object_name(id) AS varchar(50)) AS [name],
SUM(CASE WHEN indid < 2 THEN CONVERT(bigint, [rows]) END) AS [rows],
SUM(CONVERT(bigint, reserved)) * 8 AS reserved,
SUM(CONVERT(bigint, dpages)) * 8 AS data,
SUM(CONVERT(bigint, used) - CONVERT(bigint, dpages)) * 8 AS index_size,
SUM(CONVERT(bigint, reserved) - CONVERT(bigint, used)) * 8 AS unused
FROM sysindexes WITH (NOLOCK)
WHERE sysindexes.indid IN (0, 1, 255)
AND sysindexes.id > 100
AND object_name(sysindexes.id) <> 'dtproperties'
GROUP BY sysindexes.id WITH ROLLUP) AS X
ORDER BY X.[name]
the problem is that the sum of all tables is not the same size when i make a full database backup.
example of this is when i run this query against my database i see a sum of 111,899 KB that they are 111MB,but when
i do full backup to that database the size of this full backup is 1.5GB,why is that and where this size come from?

I actually work in an organisation and we have to find a solution about the data consistancy in the database. our partners use to send details to the organisation and inserted directly in the database, so we want to create a new database as a buffer database to insert informations from the partners then make an update to the main database. is there a better solution instead of that?

I am trying to resize a database initial log file from 500M to 2M. I€™m using€?
ALTER DATABASE <DBNAME> MODIFY FILE ( NAME = <DBLOGFILENAME, SIZE = 2 ) "
And I'm getting "MODIFY FILE failed. Specified size is less than current size." I tried going into the database properties and setting the log file to 2M, but it doesn€™t keep the changes.
Any help with this process?
I have a situation where I need to migrate data from an older platform to a newer one. The data from the old system(s) will be available on DAT tapes. All database construction on the new system will be identical to the old one in size and schema, except for one table (call it "ARCHIVE").
If the ARCHIVE table on the old system is 210MB, and the ARCHIVE table on the new system has the same attributes but has been expanded to 380MB in size, can I simply restore the dump for the old table into the new ARCHIVE?
Empirically it works (I have done it with apparent success two times) but I seem to recall that backups are done by pages, and I'm concerned that there may be conditions not being met by simply doing the restore the way I'm planning to do it.
Also, are there any tests or checks built into SQL which I can use to check table integrity on the target ARCHIVE table after the restore?
Any help is greatly appreciated.
Best rgds,

Is it generally or almost always better to have multiplesmall SPs and functions to return a result set instead ofusing a single big 1000+ lines SP?I have one SP for example that is 1000+ lines and earlyanalysis of the SP I see it first has 3 big blocks of codeseparated by IF statements. Then within each IF blockof code I see 3-4 UNIONs. UNIONs that meansthey are all returning the same columns so I amguessing these are prime candidates for becomingindividual functions or SPs, maybe even dynamic SPs.Obviously I am not showing you the code but am Iright to think this way? This same SP has about 15 JOINsincluding some LEFT JOINs and one LEFT JOIN to a (SELECTstatement) and almost all the tables referenced by theseJOINs have thousands of records, very possibly hundreds ofthousands.The SELECT statement is returning 30-40 columns froma lot of the these tables plus I also see a lot of CASE ELSEstatements within the main SELECT statement. The code ofeach CASE statement is calling a function. As an exampleif the CASE is for EmployeeID then a function is being calledto get the EmployeeID's FirstName and LastName. If the CASEis for CustomerID then another function is being called to getthe Customer Name.I am thinking to cut this big SP to many smaller SPs and/or functionsand I also plan on using table variable(s) to hold temporary resultwhile I continue processing the records from the table variablewith other code logic.Also I want to leave as the last thing to do is to convert the"machine result", i.e. EmployeeID or CustomerID to "humanreadable result", i.e. Employee FirstName and LastName,Customer Name.I am trying to test this on the Northwind's Employees table,but the Statistics IO, Time and the Execution Plan aresomething I've only started to use. I am unable to makeconclusion which method is better. I'll work on posting anotherpost specifically with details to this test that I am currently doing.My opinion is that by having 1 single SP with 15+ join causea lot more locking than if I would run smaller SPs and store theresult into temp table variables and continue processing theremaining code logic.I would like to know what you think and if I am right or wrongon how I want to optimize this SP?Thank you

I have a scenario where I am trying to set up multiple database instances for multiple test/development environment(s) for each group where the test/dev environment will contain a copy of what was in the production environment.. The test/dev environment can be refreshed on demand based on the prior night's full backup of the production environment.. This is good for our web developers and for training purposes, as the test environment(s) can be played around with, and will retain data for as long as the developers/testers/trainers need it, and then can be refreshed to the most current data when everyone in the group decides they want it refreshed...
Normally, this works out well...
However I am having a file size issue...
The production database was pre-allocated (a long time ago) to a large file size (probably to reduce external fragmentation).... So even though the backup file is only 5GB, the production database file itself is something like 40GB... I believe the production database has a maintainance plan on it already that rebuilds the indicies each weekend, etc...
Anyhow, the problem is that when I restore the 5GB database back into a newly created database file, the file expands all the way up to 40GB again, even though the backup file is 5GB...
Normally this would be fine, the problem is that I am trying to create multiple environments, and I do not have the disk space on my test/dev server for 40GB (plus another 15GB or so for the transaction log) multiplied by each of my test/dev environments... It would be much nicer if I could get this down to 5GB (or heck, even 10GB), since I know for sure that the total amount of data in the database doesnt exceed 5GB, and I have plenty of space on my disk for 5 (or 10) GB multiplied by each of the environments I want to create...
I have tried DBCC SHRINKDB and I have tried DBCC SHRINKFILE with the truncate after the restore, which seems to work but doesn't....
I have also tried to go into the database properties and change the "initial size" but that doesnt do anything etiher
Is there any way to get this file back down to a manageable size after the restore??
Or better yet, is there a special method to restore the database so it wont 'expand' back out to 40GB in the first place??? Perhaps some option to tell the restore process that even though the source database had a 40GB pre-allocation, that the database I am restoring into doesn't need to be pre-allocated??
Alright. I'm stuck. I admit it!
I have a bunch of names, and each name can have one or more 'roles'(operator, reader, key operator, etc. Just random words really.) attached to it.
Using reporting services, I've managed to get the information I need with relative ease... the only problem is, with 900 some records to display, it's current length of 41 pages with just one column going down the left side of each page is not exactly preferred by my superior (can't say I blame him really. Looks kind of odd!)
It looks like this right now:
Name1
Function
Function
Function
Name2
Function
Function
Name3
Function
Function
etc all the way down to page 41
I need it to look something like this:
Name 1 Name 4 Name 7
Function Function Function
Name 2 Name 5 Function
Function Function Name 8
Function Function Function
Name 3 Name 6 Function
Function Function Function
etc. Or some variation of...
I've fiddled around, and merely adding one extra column to the initial table-layout with the same =(!UserName etc) just merely replicates the data in the second column... not giving me the new stuff.
I'm quite new to reporting services, but none of the tutorials I've seen/done seem to accomodate for this... Heeelp!
I'm having problems with handling a very large amount of user records - about 100.000 - 150.000 records. Instead of selecting all of them at a time, how do I f.ex. select 1000 of them? (f.ex. get nr. 1 - nr 1000, then get nr. 1001 - nr. 2000) ???

Hi.
I am almost wrapping up a project of my own and I will have the option to restore the database, so dropping the existing one and then running the SQL script to create the database, tables, stored procedures and so on.
My question is, (using .NET 2.0 C#) - what is the best way to resolve the "cannot drop database as it is currently in use" message, or some message of the similar sort?
Even though I specified "USE MASTER" in the commandText string, there will be somewhere, in a situation, where the database will still be in use.
How can I forcefully make it NOT in use, drop it and do other things I like to?
What is the best way?
Many thanks!
Hello,
I'm looking at using full-text indexing for tables to query. I have some smaller fields (varchar(50) that stores names) that I was contemplating using full-text indexing for. I was just curious if it is worth it?
Basically the data that will be there are one-word names, without any spaces or whatnot.

Hey guys,
I'm wondering how most people manage very very large backups. What is the best approach to breaking up the backup files if you're restricted to a drive size (450gig in my case). I unix, you can pipe the backup to gzip and split, I'm not sure how the same thing could be accomplished in windows.
Thanks,

Hi!
Do you now if it is possible to make database unavailable for users after business hours and how.
Thank you in advance,

No, I don't need a step-by-step (necessarily). I've been looking at W3Schools tutorial and it says to:
Code:
CREATE TABLE Person
(
LastName varchar,
FirstName varchar,
Address varchar,
Age int
)
But what is that? A text file saved with a .sql extension. Something typed at a command prompt? Is there an SQL interface?

I work as a computer repair tech for my company and have been offered the opportunity to do a project. I'm looking to make a database of about 2000 peoples fingerprints (2 copies of each finger). We have Microsoft SQL Server but I have no Idea where to start. The vision is, to have an RFID scanner and have everyone swipe their badge then scan their prints and it automatically associates their prints with the badge number. Is there an easier or more simple way to do this or do you have any pointers on where to start? any help will be greatly appreciated. Thanks.:angel:
