Hughe Logfile After A DELETE
Feb 3, 2004
Hi
I have a business case where I have a database with a size of 2 GB. In my business case I want to delete 70% of the contents in the database. During the delete the size of the database(including the logfile) grows up to 10 GB. When I look on the database in the SQL Server Enterprice Manager there are only 700 MB used of these 10 GB.
The deletes are performed with ordinary SQL-statements "DELETE FROM X WHERE Y = 1 AND Z = 2..."
Thankfull for hints on how to solve this problem.
Regards,
Peter

Hi, maybe someone has some clues to the following situation. Suppose from a SQL 7 database, only the log .ldf files are lost. All datafiles are present. Suppose there is no backup of this database. SQL Server will put the database in the SUSPECT status. The following question is very interesting to me: Can one recover from this situation??? I ask this, because when datafiles are lost, it's obvious that you have lost data, but since the transaction log files are a "bit special", I just wonder how one can survive such a situation.
I know that IF a database has only ONE log file associated with it, and this one log file gets lost, SQL Server will create on startup a new log file. But with multiple log files, it does not behave in this sympathic manner. Is there perhaps any way to recover (for example, an undocumented dbcc command or so) ?
I surely will appreciate any tip or suggestion !! Thanks!!!

Hello guys!
I would like to clear the logfile. Could anybody tell me how to do this?
What I would like most would be to run SQL-Server without any log-file (while development). But I suppose that this is not possible.

Dear all,
I am using SAP with MSSQl 2005. My transaction logfile is full. I took backup of transaction logfile and it should be truncated and shrink after the backup, but it did nothing. There is no error but the file size remain same.
I tried from SQL server management studio selecting database--right click--shrink--file. Then i try to release unused space, shrink, but not worked.
I also checked these steps while the SAP system was stopped.
Can anyone guide me what to do now?
Thanks

Hi there,
I want to write a sql query (for SQL7 & 2K) that gives the size and space used of the log file for a given database. I can do it for data files using sysfiles/sysindexes, but can see how I can do it for the logfile.
I know I can use DMO or dbcc sqlperf(logspace), but I want to understand how and where the information is kept in system tables.

Hi, i am not familiar with MSSQL so maybe it's not as difficult to you as it is to me - in brief:
SQL version: Microsoft SQL Server 7.00 - 7.00.699 (Intel X86)
Errorlog shows:
Starting up database 'CH2'.
Opening file E:CH2DATA1CH2DATA1.mdf.
Opening file E:CH2DATA2CH2DATA2.ndf.
Opening file E:CH2DATA3CH2DATA3.ndf.
File D:CH2LOG1CH2LOG1.ldf does not exist - unable to activate.
Enterprise Manager
Shows database CH2 (suspect)
Executing script:
sp_add_log_file_recover_suspect_db CH2, CH2LOG1, 'D:CH2LOG1CH2LOG1.ldf', 1000
Shows errormessage "The database 'CH2' does not exist."
How can i get a new logfile?
What if i created a new db 'CH2' and then replaced the data files?
What do i have to tell MSSQL to create a new logfile on startup?
All scenarios shown in Books On Line only seem to solve problems
if you do have a logfile and need more space.

I am trying to move a logfile from one disk to another. I've detached the database, moved the logfile to another disk and reattached the database. I used the sp_detach and sp_attach_db to specify the paths of the *.MDF and *.LDF. I've tried it through Enterprise Manager and with boths ways I get an error message saying: "Error 9003: The LSN (201:48:2) passed to log scan in database 'DatabaseName' is invalid". Does anyone know what this means and how I can get around this. I've even tried to attach the database with the logfile in the original path and I still get that error. Need Help Please!
Thanks

Has anyone had this problem or know how to prevent it? I received an error message yesterday from my SQL server (v7.0 with SP2) saying that the logfile for the tempdb was full. The logfile for tempdb is set by default to unlimited growth and the drive it is on has 24GB free. What causes this error to happen?

If I can get around taking a few databases offline, I'd like to. I need to get logfiles on a lower-capacity drive.
Ideally, I wouldn't like to have multiple logfiles swimming around. But, I was thinking that if I created a second logfile, and then backed up the transaction log, I might be able to remove the first logfile?
The other thought I had, was creating a second logfile, and then turning off autogrow on the first log.
Maybe there is a better solution? Maybe neither of these will work?
Thoughts?

Hi there,
I recently saw that the transaction log files of user dbs grow undefinitely in SQL Server 2000 - one of our customers had a 11 GB log file which totally slowed down the server.
Another customer of ours uses one of my applications logging all actions in a MSDE database file and I fear that the corresponding transaction log file will grow and block the system too - is there any way that I could shrink and set the max size of the transaction log file through SQL?
I already know the command "SHRINK FILE ('filename')" but I haven't found a SQL command to set the max size.
Thank you for any hints!

As per the old times, do we still need to have the SQL server database's data file and logfiles seprately while we are even using Fusion IO?
In my case, all the drives G and H are from Fusion IO.
So, will it really matter if both my Data and log are on G drive or should I still have them separately on G and H Drives.

Can anyone tell me why my SQL2000 database has grown aprox 15 % and my Log file 20,000 % when I attach it to SQL2005 .I've Thousands of Databases to Upgrade, but with the log file increasing to more than the size of the Database Its going to be a struggle !
It also takes a fair ammount of time to attach,
I suspect there is some reindexing going on , as when I try to reattach to SQL 2000 I get index errors ?
Is the re anything I can do in advance to reduce the database growth ?
I know I can truncate the log afterward but the peak diskspace consumed during my Migration may be an issue !
Thanks for any help

I have a problem that looks like it has not been discussed before inthese groups.I have a simple SQLAgent job that runs sp_who (could be anything, butlet's just say sp_who for this example). I have set the jobstep towrite to an output file "T:out.txt". If the job is owned by anadmin, it runs fine and writes the output file. If it is owned by anon-admin user, it gets the following error msg:Warning: cannot write logfile t:out.txt. Error 1059 : Circularservice dependency was specified. The step failed.I know about setting up the SQLAgent CMDExec proxy account, and havedone that. In fact, both SQLAgent and the SQLAgent cmdexec proxy usethe same domain account, which is in the administrator group of thelocal server. So, I know that security is not the issue.When a simple job runs and writes to an output file, what service orservice group could it be trying to start or modify? I looked throughthe list of Services, and could not find any circular dependencies.Is there a utility to detect this? Why would running under onecontext (as an admin) be ok while the other context (non-admin on SQL,but using the same admin domain service account) fails?Thanks in advance for any info you might have.

I am having difficulty restoring a database (DB_1) with 2 datafiles and one log file, DB Structure is as following:
Filegroup PRIMARY with file name 'fnm_data' with physical file name and location D:dbfile_1.mdf,
Filegroup 'FG1' with file name 'fgnm1_data1' with physical file name and location F:dbfile_FG1.mdf,
One log file with file name 'fnm_log' with physical file name and location (E:loglog_db.ldf)
{Note} Logfile resides on E drive whereas Datafiles reside on several other drives.
I need to restore the DB on another machine. And I need to move the log file to a drive other than E.In this case it is K drive. Hence I have used the following code,
restore log DB_1 from disk='M:kupccciclog.txt'
WITH RESTRICTED_USER , MOVE 'fnm_log'
TO 'K:DBlog_db.ldf', recovery, replace,RESTART
go
When I try to restore from backup files, I keep error message saying "Physical file name E:loglog_db.ldf may be incorrect." 'fnm_log' cannot be restored. Use Move command to identify a valid location for the file.
Even though I am using Move command to move the log file.
Then I found that if I create a drive with E: and a folder named 'log' then restore program runs alright. That is, when E:log exists then code does run smoothly. All the restore code is looking for the presence of path of the log file from where it is been backed up. In this case it is E:log folder. Once the database is restored I could kill that directory and nothing happens. Also log file has been restored on K:DB only.
Why the restore code is looking for the initial drive letter and path even though I have used Move command? Is there an issue in my code?
Any help will be highly appreciated.

When trying to install Business Contact Manager (BCM) for Outlook 2007, the setup failed and I was refered to a log file in my Local Settings/Temp folder. The log actually says that Business Contact Manager was installed sucessfully! BCM is supposed to install SQL Express 2005 as an instance or as instance if SQL Express is already installed. There is an MSSMLBIZ instance in Services..
Who can I send the Log File to for analysis and the fix feedback?
When I first went into Computer Management and clicked on Services and Applications in the left panel, the error message appeared "Snap-in failed to intialize. Name: SQL Server Configuration Manager CLSID:{CA9F8727-31DF-41D2-975C-887D84903967} This message diappeared when I clicked on Services and Applications again. Under Services, there are 3 SQL services - one is an application that was uninstalled 3-4 weeks ago and I disabled this service. The other 2 are: SQL Server (MSSMLBIZ) and the other one is SQL Server (SQLEXPRESS) When I tried to start either of the last 2, the message appeared: Services "Could not start the SQL Server (MSSMLBIZ) service on Local Computer. Error 3: The system cannot find the path specified. Under Program Files/Microsoft SQL Server/MSSGL.1 folder is mostly empty. So, it seems like the Path in the Registry is not valid and that nothing is being installed in the MSSQL.1 folder. If so, how do I fix this?
How do I get the BCM SQL instance to install and run properly? what do the messages in Services mean and how do I resolve these.
Thank you!
Gary

I am using Master Data Service for couple of months now. I can load, update, merge and soft delete data in MDS. Occasionally we even have to hard delete data from MDS. If we keep on soft deleting records in a MDS table eventually there will be huge number of soft deleted records. Is there an easy way to hard delete all the soft deleted records from all MDS tables in a specific Model.

Hello:
Need some serious help with this one...
Background:
Am working on completing an ORM that can not only handles CRUD actions -- but that can also updates the structure of a table transparently when the class defs change. Reason for this is that I can't get the SQL scripts that would work for updating a software on SqlServer to be portable to other DBMS systems. Doing it by code, rather than SQL batch has a chance of making cross-platform, updateable, software...
Anyway, because it needs to be cross-DBMS capable, the constraints are that the system used must work for the lowest common denominator....ie, a 'recipe' of steps that will work on all DBMS's.
The Problem:
There might be simpler ways to do this with SqlServer (all ears :-) - just in case I can't make it cross platform right now) but, with simplistic DBMS's (SqlLite, etc) there is no way to ALTER table once formed: one has to COPY the Table to a new TMP name, adding a Column in the process, then delete the original, then rename the TMP to the original name.
This appears possible in SqlServer too --...as long as there are no CASCADE operations.
Truncate table doesn't seem to be the solution, nor drop, as they all seem to trigger a Cascade delete in the Foreign Table.
So -- please correct me if I am wrong here -- it appears that the operations would be
along the lines of:
a) Remove the Foreign Key references
b) Copy the table structure, and make a new temp table, adding the column
c) Copy the data over
d) Add the FK relations, that used to be in the first table, to the new table
e) Delete the original
f) Done?
The questions are:
a) How does one alter a table to REMOVE the Foreign Key References part, if it has no 'name'.
b) Anyone know of a good clean way to get, and save these constraints to reapply them to the new table. Hopefully with some cross platform ADO.NET solution? GetSchema etc appears to me to be very dbms dependant?
c) ANY and all tips on things I might run into later that I have not mentioned, are also greatly appreciated.
Thanks!

I am having great difficulty with cascading deletes, delete triggers and referential integrity.
The database is in First Normal Form.
I have some tables that are child tables with two foreign keyes to two different parent tables, for example:
Table A
/
Table B Table C
/
Table D
So if I try to turn on cascading deletes for A/B, A/C, B/D and C/D relationships, I get an error that I cannot have cascading delete because it would create multiple cascade paths. I do understand why this is happening. If I delete a row in Table A, I want it to delete child rows in Table B and table C, and then child rows in table D as well. But if I delete a row in Table C, I want it to delete child rows in Table D, and if I delete a row in Table B, I want it to also delete child rows in Table D.
SQL sees this as cyclical, because if I delete a row in table A, both table B and table C would try to delete their child rows in table D.
Ok, so I thought, no biggie, I'll just use delete triggers. So I created delete triggers that will delete child rows in table B and table C when deleting a row in table A. Then I created triggers in both Table B and Table C that would delete child rows in Table D.
When I try to delete a row in table A, B or C, I get the error "Delete Statement Conflicted with COLUMN REFERENCE". This does not make sense to me, can anyone explain? I have a trigger in place that should be deleting the child rows before it attempts to delete the parent row...isn't that the whole point of delete triggers?????
This is an example of my delete trigger:
CREATE TRIGGER [DeleteA] ON A
FOR DELETE
AS
Delete from B where MeetingID = ID;
Delete from C where MeetingID = ID;
And then Table B and C both have delete triggers to delete child rows in table D. But it never gets to that point, none of the triggers execute because the above error happens first.
So if I then go into the relationships, and deselect the option for "Enforce relationship for INSERTs and UPDATEs" these triggers all work just fine. Only problem is that now I have no referential integrity and I can simply create unrestrained child rows that do not reference actual foreign keys in the parent table.
So the question is, how do I maintain referential integrity and also have the database delete child rows, keeping in mind that the cascading deletes will not work because of the multiple cascade paths (which are certainly required).
Hope this makes sense...
Thanks,
Josh

I'm trying to clean up a database design and I'm in a situation to where two tables need a FK but since it didn't exist before there are orphaned records.
Tables are:
Brokers and it's PK is BID
The 2nd table is Broker_Rates which also has a BID table.
I'm trying to figure out a t-sql statement that will parse through all the recrods in the Broker_Rates table and delete the record if there isn't a match for the BID record in the brokers table.
I know this isn't correct syntax but should hopefully clear up what I'm asking
DELETE FROM Broker_Rates
WHERE (Broker_Rates.BID <> Broker.BID)

The requirement is: I should allow single row delete from a table but not bulk delete. An audit table should get updated if there is any single delete or single update. So I wrote the triggers as follows: for single and bulk delete
ALTER TRIGGER [dbo].[TRG_Delete_Bulk_tbl_attendance]
ON [dbo].[tbl_attendance]
AFTER DELETE
AS
[code]...
When I try to run the website, the database error I am getting is:Transaction count after EXECUTE indicates that a COMMIT or ROLLBACK TRANSACTION statement is missing. Previous count = 0, current count = 1.
