I have SQL Server 2005 Express Edition with Advanced Services running on a small web server. It all runs fine, but every now and then the log files grow and grow and eventually use up all the disk space of 30GB. As a quick fix, restarting SQL a couple of times clears out the logs and everything is up and running again. Any ideas on how to stop this happening?

Coming straight to the problem -
I need to write text files of the size more than 1GB! First thought of doing this with BCP but then fetching data from stored proc was taking too long (more than one hour) and so BCP did not seem to be the right option as we have less flexiblity in terms - handling errors, knowing the status as to what point the writing has been complete etc. Most importantly getting such a huge amount of data did not seem to be a one time job! So I am now thinking about writing a CLR procedure which fetches smaller amount of data at a time and writing to file. Something like - open connection, get data, close connection, write to file and continue in cycles of this till whole file is written. Does this makes sense considering the amount of data to be fetched?
Any suggestion/comment on this will be much helpful!
Hi there - can anyone advise on the following issue. We have recently performed some server side tracing on a particular SQL instance over 24hr period. We are now attempting to load these into a database for analysis. Here lies the problem.
When we are loading the profiler trace files (one at a time) into the database the transaction log is growing at an excessive rate. Even though the database is in SIMPLE mode.
We are loading the traces using the command:
INSERT INTO sqlTableToLoad
SELECT * FROM ::fn_trace_gettable('MytraceFileName', DEFAULT)
Can anyone advise how we could possibly get round this issue as we're running out of space due to the transaction log.
Thanks

I have a TRANSACTION table with 150 million rows.
I have a USER table.
Each user has about 600 records in the TRANSACTION table.
The TRANSACTION cluster index is on USERID + RECID . The second index is on USERID + Fieldx + Fieldy.
The TRANSACTION table gets about 1.4 million inserts in a normal day and about 40,000 updates.
I want to go through the USER table and delete all users who have not visited me in a while.
I want to do this without substantially hindering performance in a production environment. I can perform this over a week period or two if needed.
The best way I thought of doing this was to grab x amount of users in a cursor and loop through deleting their corresponding TRANSACTION records.
Does anyone have any ideas on a better way. What is going to happen to my indices during this time ?
Thanks !!!
Dear all,
i have problems with log .
the mssql write 4 G log so plz how can i Eliminate log huge size
I just peeked at my DNN setup and I found that I have a transaction log about 98 gigs large, compared to a DNN database that is only about 250 megs. Crazy, huh?
Do you happen to know what I need that transaction log for? Can I just delete it or will it break my SQL db? Is there a way that I can keep only maybe a week of transactions in it so it doesn't grow so dang large?
Thanks in advance for your response!!

One of my production databases is currently 51 mb. The transaction log is well over 5 gig. I have tried truncating and then shrinking the log through the use of SQL utilities. This does not work! How can I quickly resolve this problem without tampering with the production environment?
Thanks in advance.

I am not a DBA and I run a personal web site that has gotten pretty large. I have never done anything to maintain my sql server, and now my transaction log is 10 Gigs and my data is only like 300 Megs. I am starting to get a memory leak with the sql service. What should I do? Is it bad to have a huge transaction log. I am not familiar with any of this stuff, so someone please point me in the right direction.
View 3 Replies View RelatedHi all,
I found my database log file is 26GB and the database file is just about 280MB. We are doing full backup everyday. However, my sql server seems running very slow now and please advise:
1. How can I decrease/truncate my log file?
2. Would the huge size of the log file be the reasons slowing up my sql server?
3. Would anyone give me direction knowing more on the transaction log?
Thank you and appreciated!
Hi guys, its my first post! Its also like my first time really diving into sql. We are using sharepoint on site here along with sql server 2005, one of our log files is 255 GBs and needs to be made smaller very fast!! We are almost out of disk space and the log is growing fast.
I am very new to sql and dont even know where to go to enter commands, so youll have to bear with me here. I've read about truncating and shrinking and some other things, I am just worried and dont want to mess anything up. I know this is probably a simple task, but like I said, with the truncate command I was reading about, I dont even know where to go to type it in!!! If someone could please help it would be much appreciated. Thanks so much.
Hello, newbie here...
I have a huge dataset in MS SQL Server, over 11 million records of machine data taken every four seconds. I really don't need samples of this data at this interval. I'd like to run a query to retrieve my data for every 30 minute interval. I know enough SQL and DTS to SELECT was fields I want, and how to direct it to a CSV file, but I'm not sure how to manipulate the TimeStamp field in the query to only pull data every 450 records.
TIA
Hey everyone.
I have a problem and I am sure someone here can help. Lat night my DB was working fine, as it has been . This morning I get to the office and now everything has gone to hell in a handbag .
I can no longer connect to my sql2005 DB I get this error when trying to place an order on our order page.
"There was a problem with the website:An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: TCP Provider, error: 0 - No connection could be made because the target machine actively refused it.)
The error has been logged."
I also notice the sql agent will not start. Any the former owner of the Co. had a eval version of sql management studio the must have just expired(could this be causing it?)
Any help anyone can offer would be great.

Hello,
I have a very big T-SQL script (~24mb) and I need the SQL Server on my hosted site to execute it.
Right now, I have a web page that uses Sql.Connection.ExecuteNonQuery () to do it, but the .NET process runs out of memory when I load the file into a C# string.
How would I go about executing this T-SQL script on the server?
Is there such a command:
EXECUTE SCRIPT "myscript.sql" FROM DISC
?
thanks.

Good evening:
We're porting an old app written in ASP.NET 1.1433 and SQL 2000 to ASP.NET 2.0 and SQL 2005. In the old app we have a few data grids that are populated from a dataset pulled from the database. We use a SQL query that we build based on more than 10 different user inputs, the result of which is an enormously complicated SQL string. We'd like to move this processing into a SPROC in the 2005 database.
Rather than writing stored procedures to create the SQL SELECT statement, is it possible to pass an entire select state ment to a SPROC and have it executed within? We're trying to capitalize on paging in 2005 using ...ROW_NUMBER() OVER (ORDER BY PM ASC)... and building the string using IF ELSE statements is mind numbling complex and tedious.
And suggestions woudl be great.
Thanks,
Brad
One of my databases is approxiamtely 1.5 GB's but when I run a backup the backup file explodes to 38GB's.
What is the proper usage of Shrink Database, is this safe or is there another method to reduce the size?
The log file for my database in SQL Server 2005 is huge. How do I get empty it or in effect shrink it or start it over?Thanks

I am using SQL Server 7 and have about 5 databases. One of them has a data file of about 10 Meg, and most of the others are larger. I do a nightly backup to both a local and mapped drive. On both, the size of the backup file for this database is more than 500 Meg, but the rest appear to be an appropriate size. Does anyone know why this would be happening? The database works fine, it does not get a lot of insert/delete activity and I run DBCC every weekend. If anyone has any ideas I would sure like to hear from them.
View 1 Replies View RelatedDoes anybody know why BCP on v6.5 grabs so much memory for SQL Server? I have a few table imports where the BCP process will consume over 460MB of RAM during the imports.
The BCP cmd file is executed via an xp_cmdshell call. The server has 2+GB of RAM, but the BCP process effectively flushes large amounts of data from the buffer. It takes quite along time for the cache to recover from this, and after this, the rest of the nightly processes run much slower, as they end up having to hit the drives to retrieve information that should already be in cache.
If anyone can shed some light on this it would be much appreciated.

I have a job that selects alot of data from one database into another.
Can I choose not to log this operation (doesn't need to be and the log fills up before it's done)
Thanks..
type of code:
Insert into database_1
Select * from database_2
I have a huge log file (285M) on SQL Server 7.
The database itself is about 10M.
How can I reduce the log file ?
Is it possible to build it again from scratch ?
I tried the Truncate Transaction Log but it didn't help.
I have a 2 GB text file(semicolon delimited), which I need to

Thanks.

Hi all our It Admin is having issues with the backups. He was doing full backups every 4 hours with backupExec, which means thats way too much. But now hes trying to do a simple recovery now, because obviously the transaction logs have not been truncated. Its a big mess, I'm not involved in this part, they handle the backing up and permissions. Transaction logs are huge??
Any suggestions??
I need to compare if two developers did the job correctly and created identical tables.
The problem is more complex, but I will try to solve it somehow if I solve the problem of comparing two tables (let them be in different SQL Server 2008 databases) and their properties. No data needs to be compared.
I have an xml file of 44 Gb (Not Meg, its really GB) . Delivered by the Danish custom authorities.
My problem is simple - How to import such a beast? I have seen a limit of 2.1 Gb everywhere.

View 3 Replies View RelatedHi,
i have 4 tables, each consist of app. 10000000 rows.They have same columns (fTime[datetime] and bid[money]).What i wanna do is to collect all of datas into one of the tables, in ascending order by fTime.
PS i wanna do it as fast as possible as well
I have a medical DB with the loads 150,000 transactions per month. Each month, I load the tranactions into a table for the current year. I also have to update records for prior months based on current month information.
For example, out of 186,000 dump records...150,000 will be loaded into the main table and 36,000 will be used to update records already loaded into the main table.
The tables have 90 columns, I have a clustered PK using [Soc_Sec_Number] & [Month] & [Row Index]. I need the row index counter (like auto number in MS Access) because I can have multiple transactions per month for the same Soc Sec Number.
===========================================================
My steps are
1) Load 150,000 records into main table (For december, this makes the table have 1,800,000 rows
2) Run queries for the remaining 36,000 rows to update records already loaded into the table containing the 1,800,000 rows.
3) The 36,000 queries have to be splits depending upon the update type code, So I am actually running 6 queries using 6,000 rows each against the 1,800,000 records.
The update queries are using inner joins with [Soc Sec #] and [Date], part of my composite Primary Key on both tables.
=============================================================
Problem
This process takes forever, about 4 hours per monthly update. As the months go out, the main table gets larger and the time increases. It took almost 24 hrs to get from January 2004 to June 2004.
I am running Sql Server on my PC, no seperate workstation. My PC has 2.8 GHZ with about 1 Gig in RAM. Could my PC specs be too low. I noticed that the task mamager shows sqlservr.exe using over 657,000 mb of RAM when running.
I also ran a simple Select MAX(Soc_Sec_Number) query that took over 5 minutes. This is way too long especially since Soc_sec_Number is part of the composite PK.
Could my queries actually take that long or are my pC specs too low. MY PC seemed to freeze after the JUNE update? Any help appreciated.
I have an 80 gig server. My client has sent me a backup of their db. The actual data file is 47 gigs. The client didn't truncate the transaction log, and on the backup , it is 37 gigs.
Question : when restoring this to my dev box, do I need to restore the transaction log, or, is there a way to truncate it so the 37 gigs isn't transferred to the server?
Thanks
