SQL 2012 :: Restore DB Without LDF File - Special Case DB Shutdown In Mid Transaction
Nov 14, 2014
Got this situation, trying to do Use SignleMode to recover my handing db, after that lost ldf (and physically too). Tried all things thru SSMS and scripts (below) that I know with no result, is there anything else I can try to recover it, I don't need log file.
An exception occurred while executing a Transact-SQL statement or batch. (Microsoft.SqlServer.ConnectionInfo)
Could not open new database 'MyLostDB'. CREATE DATABASE is aborted.
File activation failure. The physical file name "C:xxxMyLostDB.ldf" may be incorrect.
The log cannot be rebuilt because there were open transactions/users when the database was shutdown, no checkpoint occurred to the database, or the database was read-only. This error could occur if the transaction log file was manually deleted or lost due to a hardware or environment failure. (Microsoft SQL Server, Error: 1813)
EXEC sp_attach_single_file_db @dbname='Commissions',
@physname=N'C:SQLDataMyLostDB.mdf'
GO
CREATE DATABASE Commissions ON
(FILENAME = N'C:SQLDataMyLostDB.mdf')

I have Full database backup upto previous day and transaction logfile of Today transaction. my database has crashed. I have restored previous day's Full backup. I have faced difficulty to restore today's transaction from today's transaction log. What are the steps to restore full database back and one day's transaction log file. Note: there is no differential database backup and transaction backup.
I am just trying to find a good article on the process SQL goes through when shutting down and starting up, so far I have not found anything definitive on Google. I am assuming a checkpoint is invoked and committed transactions are written to disk, while uncommitted are rolled back, but I would like an official textual description of what happens.
I want to install SP2 for SQL 2012, but I am not sure how my instance would be affected.
I want to know if the instance will go down for any amount of time during the update? I can schedule a server reboot after hours, but don't want to apply the service pack if it will take the instance offline at any point.
i have  .bak file  downloaded from internet , and i also have istalled  sql server  2012.my problem that i can not restore  this  .bak file and get this error massage :

hi All :I have an insert statement which readsINSERT Into TableA (Col1)SELECT CASE WHEN Col1 LIKE '%[a-z]%' THEN 999999 ELSE Col1 END ASCol1,FROM TableB**********************TableA. Col1 has a datatype of Int.TableB. Col1 has a datatype of varchar.My insert is failing as it is trying to insert special character,identifying a in the input columnHow can i write a similar case statement to filter out specialcharacters and replace with 99999Also can you refer me to a place where i can have a list of specialcharacters and if need be write mulitple case statements to filterthem out.thanksRS
Database is in simple recovery mode, and published with transaction replication push subscription, just one subscriber but the database is huge. I don't want to overwrite the schema at the subscriber either.
I had to run an alter database command on a published database, it created so many logs that an extra drive had to be added along with an extra log file to accommodate all the logs.
The problem I have is I'd like to know clear the file of logs so I can drop the temporary log file, and give the drive back, but I cannot.
I have tried dbcc shrinkfile with the emptyfile option but it never clears, I have also tried it with notruncate and truncateonly options (mainly out of desperation).
I do not need to worry about point in time restore as a full backup is taken before and after the operation. After which the database will be put back into Full recovery mode.
I have looked at log_reuse_wait_desc and the file says 'Replication', so I am now thinking the file cannot empty because replication is keeping one of the VLFs active. I tried dropping and recreating the subscription hoping it might free something up and I could get somewhere, but it made no difference.
Do I have to remove replication completely to get round this? Surely not.
I have also tried putting the database back into full recovery mode, doing a full DB backup, and a transaction log backup, but its made no difference, which is also what makes me think a portion of the log is still active because of replication, and perhaps the transactions have not gone through to the subscriber, which raises another question, why not?
I have not tried restarting SQL server, as I'd like to know a way out of this without having to do that, plus I do not think it would make any difference anyway.
I received an alert from one of my two secondary servers (all servers are running 2012 SP1):
File 'E:SQLMS SQL ServerMSSQL11.MSSQLSERVERMSSQLDATAMyDatabaseName_DateTime.tuf' is not a valid undo file for database 'MyDatabaseName (database ID 8). Verify the file path, and specify the correct file.
The detail in the job step shows this additional information:
*** Error: Could not apply log backup file 'MyDatabaseName_DateTime.trn' to secondary database 'MyDatabaseName'.(Microsoft.SqlServer.Management.LogShipping) ***
*** Error: Table error: Page (0:0). Test (m_headerVersion == HEADER_7_0) failed. Values are 0 and 1.
Table error: Page (0:0). Test ((m_type >= DATA_PAGE && m_type <= UNDOFILE_HEADER_PAGE) || (m_type == UNKNOWN_PAGE && level == BASIC_HEADER)) failed. Values are 0 and 0.
Table error: Page (0:0). Test (m_freeData >= PageHeaderOverhead () && m_freeData <= (UINT)PAGESIZE - m_slotCnt * sizeof (Slot)) failed. Values are 0 and 8192. Starting a few minutes later, the Agent Job named LSRestore_MyServerName_MyDatabaseName fails every time it runs. The generated log backup, copy, and restore jobs run every 15 minutes.
I fixed the immediate problem by running a copy-only full backup on the primary, deleting the database on the secondary and restoring the new backup on the secondary with NORECOVERY. The restore job now succeeds and all seems fine. The secondaries only exists for DR purposes - no one runs reports against them or uses them at all. I had a similar problem last weekend on a different database that is also replicated between the same servers. I've been here for over a year, and these are the first instances of this problem that I've seen. However, I've now seen it twice in a week on the same server.
Yesterday I received a response to my CI/CS Collation problem and therecommendation was to try and restore a CI Collation database to a CSCollation database. After creating a blank CS database a full restore(Force restore over existing database) does change the Collation toCI. I'm unsure as to how I can restore without changing theCollation. Any suggestions?
I'm trying to replace special characters in SQL SERVER and all the solutions for this RDBMS that I found, it uses loops and the source of my data it's in Oracle. in ORACLE and they use REGULAR EXPRESIONS to solve it..Do you know what its the better option to replace special characters? Using loops in SQL SERVER or REGULAR EXPRESSIONS in ORACLE ?
Create table DBInfo (Path varchar (500)) Insert into DBInfo values('/Data Sources') Insert into DBInfo values('/Data Sources/SALES') Insert into DBInfo values('/PRODUCTION') Insert into DBInfo values('/PRODUCTION/SERVICE') Insert into DBInfo values('/PRODUCTION/SERVICE/MAINTENANCE') Insert into DBInfo values('/PRODUCTION/SERVICE/LOGISTICS')

I am trying to import a file to a db table from a mainframe system. When I look at it on the PC has some special characters in it. They look like nulls and or tabs. When I try to define the fields in DTS, I only see up to the first special character. I tried to write a quick VB program to strip them out, but when VB is reading the file they get stripped out before I see them in the program. Any help would be greatly appreciated.
I have a flat file that has fields delimited by tilde {~} and rows delimited by {CR}{LF}. The problem is, my source is spitting out the {NULL} (&H00) at the end of the row.
The data displays correctly in the pre-viewer (with a non-print symbol at the end of the last field), but gives an error when I try to run the package.
Example:
€œdata€?~€?data€?~€?data€?{NULL}{CR}{LF}
I can process the row in c# using:
€œ €?
as the row delimiter. What is the equivalent notation for SSIS?
I would like to know how to import in the custom delimited text file by using SSIS. For example, instead by using tab or comma delimited, I use this character : '¶' The reason is the delimited format that SSIS provided is too common such as colon, semi colon, tab, comma and pipeline. I have the data that the user also key in the pipeline there. So I am thinking to separate the field by using this special character, but cannot see if there is anyway to import in by using SSIS.
I have a db which was never backed up!!! Yesterday a script was run on this database which deleted my existing tables and created new ones...pretty dumb i know...just one of those days when everything goes wrong...all i have is the transaction log(which had a truncate log on checkpoint enabled..).. is there some way in which i can recover those tables again??? i tried to run dbcc log (dbname,4) which showed me the transaction log with lots of rows but i could not read it ...can anywone help me to understand that transaction log???
How do I restore from a transaction Log? I use 2 separate database devices for my database (Data & Log) If data is corrupted at 3PM, can I just go and do a
LOAD TRANSACTION DatabaseName from the LogDeviceName StopAt 2:59
When I try to run that, it doesn't work. There is no option in the REstore Interface to specify to restore from only the transaction log. Do I need to DUMP the transaction log several times a day in order to do the restore?
Thanks!

Do you backup transaction log periodically? If not, sorry for that.

I need help ASAP!
For some reason, we lost a dozen of our tables with valuable data. could be a virus or something that cleared out our data.
The last backup we have is last night at 11PM. If we recover from that backup, all the users lose all of today's work!
Is there a way I can just roll back the transactions from today?????!
We accidentally overwrite some data in our DB. Bad news is we never back-up our DB. However, the system are set in full-recovery mode. From website and book, i found that it's possible to recover back the data using "Recovery DB to a Point Time" but when we try it, we found that it cannot work without any backup data.
Hi all, I had been made full backup, differential backup, transaction log backup. I want to create new database from these file backup. I did it follow: 1. Create new database from full backup file, it is ok. then 2. restore this database use transaction log backup file, an message raise : "The proceding restore operation did not specify WITH NORECOVERY or WITH STANBY. Restart the restore sequence, specfying WITH NORECOVERY or WITH SATNBY for all but the final step... " thank for reading.

Hi All, I am facing one problem. My Testing Server is down. I have taken full backup 1 hr backup. After that i have taken additional 5 TL backups. All the backups were moved to different server. Now DB Server is corrupted. Now i have to rebuild the Database Server from the available Backup and TLog Backup. But i have reliased that all the Transaction Log backup are having no naming convention in File name.
I am wondering after restoring full backup, which tlog backup i should use for next restore.
using the following syntax in SQL 2005 (win 2003) to restore a log to a marked transaction. Code runs ok but I'm never getting back to the point in time where id 13 still exists , help !
kind regards

Actually instead of creating initial snapshot ,I thought of doing Transaction Replication in 2005 with backup/Restore. Everthing worked fine for DML changes which is being replicated to subscriber. But my question is:
1)In 2005, DDL changes also replicate by default, Why i am not getting that feature while doing tran rep with backup/Restore?
Hi,Currently, I am on SQL2000 SP3 and Windows 2003.I am trying to restore the full database backup and transaction logbackup on the development server. The full database restore is not aproblem, but the transaction log restore happened during the day is.Everytime when I try to compare the transaction in the database(select the last update date from one of my table as a benchmark, thenbackup the transaction log for restore) to the development db with therestored transaction log, I got none of the transaction from the logbackup.What did I do wrong? Is my concept about using the transaction logrestore wrong?Thanks in advance.
i have been doing tests and i cannot manage to do this. here is what i have done and am trying to do:
I created a full backup of the adventureworks database
I made some updates to tables.
I created a differential backup.
I done an update update to another table, dropped a table, and done another update.
Lets say in a production envrionment i just realised the table was dropped and i wanted to go to the transaction just before the table was dropped. is this possible, or are all transactions in the log going to be lost? All i have found remotely related to this are marked transactions, but they are not what i am looking for. i want a list of transactions in the log and be able to select one as the backup point ( via SSMS or TSQL). i am not looking for a point in time restore.
We have a database on sqlserver 2005 on a schedule for transaction log backups is in place already which is happening at interval of 30mins.All these transaction logs are appended to file called 'BKP' on E drive of our server. Now i have to configure logshipping for this database.Normally logshipping process will backup the transaction log,stores it in a shared folder on primary server and then copies the backupfile to another folder on secondary server and then restored ..plz correct me till now if im wrong.Now let us say our normal trans log backup schedule is as follows T1 at 9.30am T2 at 10.00am T3 at 10.30am T4 at 11.00 am Now i decided to schedule the log shipping transaction log backup interval once in 30mins and start transaction log backup at following intervals T11 AT 9.45am T22 AT 10.15AM T33 at 10.45AM T44 AT 11.15AM So T11,T22 etc these backups are restored on standby server sequentially.
Now if Primary database goes down at 11.25am , then do i have to restore the Tlogs T1,T2,T3,T4 and make the Primary database up or i should restore T1,T11,T2,T22,T3,T33,T4,T44 for making my primary database UP..
hi, I would like to know the correct reaction for a crash in both senarios. First senario, I made a full back up at 6 am , then scheduled sql server to make transaction log back up every 2 hours (8,10,12,2 pm,4,6,8) . If I have a crash at 12:30. How would I resotre the data in the first senario....Can I restore the full back up done at 6 am then restore the last transaction log backup ( which is 12 Noon ) . I am not sure If I need to resotre the whole tran from 6 am till the time it was crashed.
Second senario,
I made a full back up at 6 am, then scheduled sql server to make Incremental backup every 2 hours (8,10,12,2 pm,4,6,8) . If I have a crash at 3:00 pm. How would I resotre the data in the second senario. ....Do I restore the full backup at 6 am then restore each incremental backup backwords ( 2,12,10,8)
AS you can see, I am not sure how to deal with this issue, I do appreciate your feedback.
We have an order posting stored procedure that's been executing for 14 hours now. This procedure has simple update statements but all the tables updated have triggers which update other tables with triggers and so on. This procedure hasn't commited yet. I have a full database backup from last night and transaction log backup from this morning while it was running. I want to kill this job and restore database from last backup. Only thing I am afraid of is that it will take too long to roll back which I have no estimate of time. Is there any faster way to get rid of all the uncommited transactions? Has anybody rolled back such a massive transaction? Any idea on how long it can take? Can it affect the overall server performance as this is the main production ERP server. I can see in profiler that this procedure is still running and not hung.
I am currently running MSSQL on DB1 server with 12 DBs I am running a full backup nightly at 8:00pm and coping it over to DB2. I am sending transaction logs every 15 minutes to DB2.
Is there a script or procedure for rolling in all the logs once the restore is finished. I realize the basic way to do this is here http://msdn.microsoft.com/library/default.asp?url=/library/en-us/howtosql/ht_7_backpc_7veh.asp But writing a script with say 22 files each for each db is fairly time consuming.
I have contemplated writing a script that takes the content of the logs directory, parses it based on db name and builds the sql statements but did not want to go through all of it if someone else has already done the leg work.
