Hello.
I need to design a database structure that will keep ALL table records and not delete anything. Every record will have associated users, but I need to keep perminant track of what every user did to any record.
Can you suggest a reading or backup method? Should I keep older versions of a record within the same table or move them to another? Or backup to log files? Any suggestions?
Thank you in advance

question 1:
i found that database log file can contain more records after performing backup database statement.
for example:
i create a database and limit the log file to 2mb. then i create a table and insert data.
If i backup the database before i insert data , the database file can contain 192 records unitl the log file is full.
If i don't perform the 'backup database' statement.
The 'dbcc sqlperf(logspace)' indicate the utilization ratio is less than 40% after inserting 192 records
why?
I list my code:
Code Snippet
create database db_test
on primary
(
name=db_test,
filename='C:Program FilesMicrosoft SQL ServerMSSQL.1MSSQLDatadb_test.mdf'
)
log on
(
name=db_test_log,
filename='C:Program FilesMicrosoft SQL ServerMSSQL.1MSSQLDatadb_test_log.ldf',
maxsize=2mb
)
go
backup database db_test to disk='db_test.bak' --- if i don't execute this line, log file can contain a lot of record
go
create table db_test..table1(col char(8000))
--insert data to fill up the database log
declare @n int
set @n=0
while @n<192
begin
insert into db_test..table1 values(replicate('a',8000))
set @n=@n+1
end
question 2:
i create a database and limit the log file to 2mb. Then i create a table and insert data in an endless loop.
After the inserting operation executing for a while, the 9002 error occurs, indicate the log file for the database is full.
But the 'dbcc sqlperf(logspace)' command indicate the unilization ratio is low, and log_reuse_wait_desc in sys.database is 'CHECKPOINT'
And I can insert data , and i'm sure the state of log_use_wait_desc is 'CHECKPOINT'.
As i known, the checkpoint can't truncate log under full recovery model. Only the back log operation can truncate the transaction log.
So log is not full, why 9002 error is encounterd. and why the log_reuse_wait_desc return 'CHECKPOINT'?
I list my code:
Code Snippet
create database db_test
on primary
(
name=db_test,
filename='C:Program FilesMicrosoft SQL ServerMSSQL.1MSSQLDatadb_test.mdf'
)
log on
(
name=db_test_log,
filename='C:Program FilesMicrosoft SQL ServerMSSQL.1MSSQLDatadb_test_log.ldf',
maxsize=2mb
)
go
create table db_test..table1(col char(8000))
--insert data to fill up the database log
declare @n int
set @n=0
while @n<>-1
begin
insert into db_test..table1 values(replicate('a',8000))
end
any suggestions?
thanks in advance.
I have a problem when i restore my .DAT_BAK file. I am getting error like "The backup set holds a backup of a database other than existing database. Restore Database is terminating abnormally".
I tried by using
RESTORE DATABASE <DATABASENAME>
FROM DISK = 'D:DATAMYTEST.DAT_BAK'
WITH MOVE 'VZAI_DATA' TO D:PROGRAM FILES..MSSQLTEST.MDF',
MOVE 'VZAI_LOG' TO D:PROGRAM FILES..MSSQLTEST.LDF',
REPLACE
And also i tried like
RESTORE DATABASE <DATABASENAME>
FROM DISK = 'D:DATAMYTEST.DAT_BAK'
WITH REPLACE
When i use like this,
RESTORE FILELISTONLY FROM DISK = 'D:DATAMYTEST.DAT_BAK'. I am able to get the output as LogicalName, PhysicalName, Type, FileGroupName, Size, etc.
Can i anyone please help me out?
Thanks in Advance,

Hi there
I'm getting this message on my third automated backup of the transaction logs of the day. Both databases are in full recovery mode, both successfully backed up at 01.00. The transaction logs backed up perfectly happily at 01:30 and 05:30, but failed at 09:30.
The only difference between 05:30 and 09:30's backups is that the log files were shrunk at 08:15 (the databases in question are the ones that sit under ILM2007, and keeping the log files small keeps the system running better).
Is it possible that shrinking the log files causes the database to think that there hasn't been a full database backup?
Thanks

Hi,
I already submitted this type of question before and i receive reply. But unfortunately i found out errors when performing on my system.
My problem regarding to this one:
Suppose i have two databases with same tables with different records and I would like to copy the records from one database to another data and vice-versa. So that both the tables contains same number of records inside the tables.
Example:
Database1 (EmployeeTable) contains 6 records.
Database2 (EmployeeTable) contains 10 records.
It should copy only those records which is not present in each other database. No duplicate records.
Before i was recommend to use Primary key, if it is not present use index.
Hope this time i could solve my problem.
Thanks.

We take a full backup in the early morning and hourly transaction log back during the working hours for one database in the production server. The application team made certain changes to the design of the said database in their development server. The backup from the development server was restored to the production server during working hours. After the restoration should we take a full backup before next transactional logbackup? Would the transactional log backup with out a full backup after the restoration of a database be valid?
View 5 Replies View RelatedHi i am looking for some advice about sql databases and wondering if anybody can help me.
First the Background.
I am in the process of writing a payroll program that uses SQL as a data store. However rather then creating individual databases for each payroll that can be ran on the system i have created a core payroll table that generates a unique id for each payroll and then reference that thoughtout the system.
Now The Problem
The problem I now have is when I work out the final pay for the employees I want to make a quick copy of the various records just in case I need to undo the net pay calculations for adjustments to the data, it is effectively rolling back the transactions to the database but I want to be able to keep them till I decide that everything is correct.
I cant take a snapshot of the entrie database because the payrolls stored within may be in all sorts of states.
I need to keep the records for just the payroll I'm working on.
Any Ideas or Solutions !!!!!
Thanks

Hi all,
I have a db with 15 tables and I want to keep records that have been deleted.
Now I don't know where to start:
Must I keep the same structure as the main db or can I also dump all the data in one table?
what are the advantages and disatvantages of the named possibilities.
If someone knows anything else please help me out.
Thnx in advance
I have a database that is just over 1.5GB and the Full backup that is 13GB not sure how this is since we have compression on for full backups and my other full backups are much smaller than there respective databases...Now my full backup is taken every Sunday night and the differentials are taken every 6 hours after the full backup. Now I have been thrown into this DBA role with little to no experience just what I have picked up and read. So my understanding of backups are limited but what I think I understand is that we take a full backup and the differential only captures what changes in the database so my question is why is my database 1.5GB but my differential is 15.4GB? I have others database that are on the same instance and don't seem to have this problem. I also just noticed that we do not rebuild the index before a full backup like we do on other instances...

View 1 Replies View RelatedHi,
I have a MS SQL Server 2005 Enterprise Edition 9.0.2153 which manages my BizTalk Server 2006 Databases. The BizTalk server installer automatically creates a job named Backup BizTalk Server (BizTalkMgmtDb) which should back up the databases and transaction protocolls.
The SQL Server Agent runs under domain-administrator account which has full access to my backup directory D:ackups.
The job executes the following steps:
Step 1: BackupFull:
Command:
exec [dbo].[sp_BackupAllFull_Schedule] 'd' /* Frequency */, 'BTS' /* Name */, 'D:Backups' /* location of backup files */
Step 2: MarkAndBackupLog
Command:
exec [dbo].[sp_MarkAll] 'BTS' /* Log mark name */, 'D:Backups' /* location of backup files */
My challenges are:
1. The job doesn't back up my databases(D:Backups is empty after executing the job)
2. I get every time the following error in error protocol of the job:
BACKUP LOG cannot be performed because there is no current database backup. [SQLSTATE 42000] (Fehler 4214) BACKUP LOG is terminating abnormally. [SQLSTATE 42000] (Fehler 3013).
I have already switched the Databases from full to simple recovery mode and vica versa, it didn't help. Also, the above stored procedures doesn't include neither the TRUNCATE nor the LOG parameters for the logfiles so I wasn't able to solve this issue by adjusting these flags.
Any help would be appreciated.
Thanks in advance,

I am using sql server 2000 and windows server 2003 standard edition:
My database backup job is failing due to lack of disk space. I am taking the backup onto E drive and the
available free space on E drive is 6.85 GB and there are no other drives I can use for the database backups.
The size of mdf file is 21 GB and that of ldf file is 4.2 GB.
The transaction log back up job of that db ran fine.
This database recovery model is Full and
Auto shrink is not checked.
There is one primary filegroup for the database.
In this situation, I am thinking of the following option:
1. Backup the db and log files onto another network shared drive.
If I want to still use the same server E drive to backup the db and log files instead of using another network shared drives.
how can I do that.
Please let me know the best way of handling this issue.
Any help is greatly appreciated. Thanks!
I neglected to backup the transaction log as part of the process of backing up the database. Now i only have the backup file for the database and no transaction log backup. When i try to do a restore on the database, i get the error on a "tail log missing" message (which i'm assuming is that it's looking for the t-log backup?).
Is it possible to restore or even restore to a new database? I'm only looking to retreive data from 2 tables within the backup file.
Thanks!
SQL Server 2005 on Windows 2003 Server x64.
We replicate a SQL2000 database (DataBaseA) to a SQL2000 database (DataBaseB) by using the Restore function and hasn't change its logical name but only the physical data path and file name. It is running fine for a year. We use the same way to migrate the DataBaseB to a new SQL2005 server with the Restore function and the daily operation is running perfect. However, when we do the Backup of DatabaseB in the SQL2005, it just prompt the error message
System.Data.SqlClient.SqlError: The backup of full-text catalog 'DataBaseA' is not permitted because it is not online. Check errorlog file for the reason that full-text catalog became offline and bring it online. Or BACKUP can be performed by using the FILEGROUP or FILE clauses to restrict the selection to include only online data. (Microsoft.SqlServer.Smo)
Please note we left the DataBaseA in the old SQL2000 server.
Please help on how we can delete the Full-text catalog from DatabaseB so we can do a backup
Many Thanks
I did tried the encryption on server "A" for database "AdventureWorks2012". Then I tried to restore to server "B". There was the certificate issue, and I thought "of course : it's encrypted ! Let's deactivate it". So here I go "ALTER DATABASE AdventureWorks2012 SET ENCYRPTION OFF".I look at sys.databases : not encrypted.I backup using no encryption, I verify using msdb.dbo.backupset : not encrypted.
I move my backup to my other server where encryption was never configured (so no certificate, nothing...), and I have the error :
Msg 33111, Level 16, State 3, Line 1
Cannot find server certificate with thumbprint '0xFA130E58C999C4919B8975999C83A75A403B11D8'.

Anybody figure a way around this:
In a development server you take a backup and you want to move the entire database to a production server. The production server does not contain the database, users, or logins in master.
When you restore the backup to production in 7.0, the users get moved to DBO because the logins do not exist and then you cannot delete them.
We are having to drop the users from the database on development, back up the database and restore it to production, then recreate the users on production.
This is bogus and did not happen in 6.5 because of the aliases.
Anybody come up with a better way?
I am fairly new to VS 2005 and SQL Server CE. I have developed a Desktop Windows application using VB 2005 and the SQL Compact Edition Database. This application will sell to users via web download.
When they download a service patch, or updated version, I wish for them to retain the data in their present database. In other words, fill the new database with the old data. The new table structures will remain intact except for added columns at the end.
Question is how to save the old data and update the new database with it. Is there an easy way to do this, or do I need to write a module to save a database copy, and update the new database with content at install time?

View 1 Replies View RelatedI have a Subscriber database updated using transactional
replication and want to create a copy for development & testing. The Distribution database is running on the

It looks like an attempt is being made to restore
replication information too. I note that
the RESTORE statement has a KEEP_REPLICATION options which implies (I would have
thought) that by default the replication information is not be restored.
Incidentally, before implementing replication, backing up
the live database and restoring the backup to a new database took < 7
minutes but running the same process with a Subscriber database backup takes
about 15 minutes.
I€™d be interested to know if anyone has any idea what I€™m

Hi,
I was wondering how I could restore a bkp file into a database with a different name. For example, I made a backup of T1.mdf and i want to restore t1.bkp to T2.mdf.
I am using VB.Net to do the backup and restore.
Is there any way of doing it?
Thanks!
i have a stored procedure that backups database on server A which i execute this SP from server B in a scheduled job. when i run this job it gives me an error:

i searched MS KB, everywhere but could not find the solution or even explanation why this happenning.
both sql servers are 2000 and they are linked.
Due to a network time skew some time ago, all of the databases on an SQL system now have the following information stamped on them..
Within Enterprise Manager (SQL 2000), The "Last Database Backup" timestamp for each database is showing the year 2025.
Our backup system runs incrementally daily and a weekly full. Unfortunately, the timestamp does not seem to be updating as the year is as I guess in the future.
Can anyone advise of a procedure so as I can wipe this time skew date from each of the databases?
Many thanks folks!
