I have a database it is 50 gb with hundreds of columns. I would like to choose a certain column and convert the data in it to .csv or excel file. How can I do that I am very new to MSSQL...
View 1 RepliesFor a database, we have 4 data files in a particular file group and the file sizes are almost 70 GB each.
Do I come across any performance issues if I create/pre-allocate an additional data file in the same file group so that the existing files don't grow too much?
In a server we had File Growth,And then We had to Add New Hard Drive And New File On It.And Now We have New server with a Huge Hard Drive.But all files remaind.Can I Reduce This files to One data file or not ?

msdb.dbo.sysmanagement_shared_server_groups_internal and

We have one table where we store all documents in one of the column called "Doc" with varbinary(max) data type.
We want to download those documents from sql table to windows explorer and i wrote BCP in sql 2005. And things were fine.
The format file I used there looks like this,
9.0
1
1 SQLBINARY 0 0 "" 1 Doc ""
Now we are in 2014 and when I try the same code with same format file, it hangs in the middle. So I changed the file to 12.0 instead of 9.0 but still not working.
is there a way to restore all file groups except one? example: Database A has 10 filegroups, but 1 of them is defunct, so i cant delete it and there's no backup for restore it.Can I create a new DB restoring the 9 good FGs from a database A's backup?

View 4 Replies View RelatedI am trying to implement the column encryption on one of the tables, have used the below link as the reference and got stuck at the last step.

I have completed the following steps so far.
- CREATE MASTER KEY ENCRYPTION BY PASSWORD = ‘myStrongPassword’
- CREATE CERTIFICATE MyCertificateName
WITH SUBJECT = 'A label for this certificate'
- CREATE SYMMETRIC KEY MySymmetricKeyName WITH
IDENTITY_VALUE = 'a fairly secure name',
ALGORITHM = AES_256,

Example by using the function
EXEC OpenKeys
-- Encrypting
SELECT Encrypt(myColumn) FROM myTable
-- Decrypting
SELECT Decrypt(myColumn) FROM myTable
When I ran the last command :
-- Decrypting
SELECT Decrypt(myColumn) FROM myTable
I get the following error :
Msg 257, Level 16, State 3, Line 2

View 4 Replies View RelatedI was running an operation to shrink file/emptyfile a data file, and then remove it.
It blocked and caused a huge mess, I suspect on the removal part. But I want to confirm that the emptyfile completed (and that the engine isn't going to try to put more data in there for when I schedule the removal part again a week or more from now).
How does the engine know not to put any more data in there, and how long does that situation last?
While i execute dbcc sqlperf(logspace); I get following values.
Database NameLog Size (MB)Log Space Used (%)

tempdb 7.429688 61.7245

BANKDB 23438.87 48.20037
WSMIRSDB 109.7422 4.839111
For database BANKDB , Log Space used(%) is 48.83% and Log size is about 23438.87 where as my database size of BANKDB is 60 GB. FULL database and Log back is done every day night one time. My database is performing slow now.
Do we need to take log backup frequently like once a 1 hour so that Log space used will be less. Same query is taking more time to execute than before in same database is it because of log file has increased.
I do index organize and rebuild once a week and stats apply nightly.
Is it correct once log space size is increasing more than 10%. Do we need to take log backup?
I have created a stored procedure for retrieving column name, as shown below
CM_id, CM_Name, [Transaction_Month], [Transaction_Year], [Invoice raised date],[Payment Received date],[Payout date],[Payroll lock date]
Now I am trying to create a temporary table using the above generated coluimns from Stored Procedure with datatype.
SQL server, by-mistake I updated values of a column in a database hosted online, is there any way undo the transaction. I didn't created any backup of the database. I read that still it can be recovered through the .ldf (log file) but unable to access it. Is there anyway to get access of the Log file or is there any way to recover the data.

Database File Placement Layout? We are planning to implement a new SQL Server 2014 OLTP Database with a 1 TB Data file and 1 TB Log File. I am looking at the possible layout of the database files and trying to determine the best possible configuration. My knowledge/research tells me that items which need separate storage due to constant simultaneous access are:
Data files – should go on the fastest reading storage.
Log files – should go on the fastest writing storage.
TempDb – involves a lot of writing at the same time the data files are being read.
Indexes - (including full text indexes) - involves a lot of writing at the same time the data files are being read.
Also, are there any benefit to having multiple OLTP Database Log files? Because SQL Server writes to the log file sequentially, I do not see any advantages to having multiple database log files. In a SQL Server 2012 Class I took last summer, under “Determining File Placement and Number of Files”, it states “Use a single log file in most situations as log files are written sequentially.”
I recently installed standalone version of SQL 2014 Standard on my work computer. I used Access before but I want to use a SQL server instead.
We have a shared drive that a file gets deposited every day at midnight. I want to be able to get this file and import it to the server (its basically a list of names).
Here what I have done so far:
I created the database
Created the file and successfully imported data into it using the Import Data feature.
I saved the SSIS package
Scheduled an Agent Job for this package to run at certain time,daily
At first the jobs would fail with a Access is Denied. I added a user under Credentials with my network account ( have admin rights on the work computer).Also added a Proxy for the Credential user I made.
Jobs fail with a “Cannot open data file” error. I tried changing things here and there, but I can’t get it to work.
I have installed SQL 2014 (Evaluation Version) on testing machine. We want to import some excel files on database. I manually created one Test Database and now trying to import excel file. Import completed successfully but I am not able to see any table created as result of Import. I tried it 3-4 times and even restarted sql services but no luck.

what is 64 KB cluster has 128 sectors?
tempdb drives should be formatted with a 64K allocation? how many files needs to created for good performance with 50GB or 100GB? ot 1TB
A little background on what I am trying to achieve first. We are moving to Azure virtual machines and we will have 8 disks on the SQL Server box. I am adding more files to the primary file group and each file will go on its own drive. I am then rebalancing data across these files by rebuilding all of the indexes on the tables which is working fine. No problems so far all is good.
I now have an additional problem. If there is a lob or blob column on the table, rebuilding the clustered index and all the non clustered indexes doesn't rebalance the blob or lob data across the disks such as it does with in row data.
I cannot find any articles on rebalancing lob or blob data because all the articles say to move to a new file group. I do not want a new file group, I just want to use the primary file group where the data already resides, and just redistribute it evenly in the same way that I can in row data which is working fine.
One solution I thought about was to BCP data out of the table, truncate the table and then BCP back into the table which I imagine would have the desired effect of distributing the data evenly over the files.
I want to set up a database role so that users can use sp_readerrorlog through SSMS. It does a check on membership in the securityadmin role.
I have tested it and can see you can grant execute on xp_readerrorlog but the SSMS GUI uses sp_readerrorlog.
I thought I could create a user/certificate and add the signature to sp_readerrorlog but it's not permitted (likely because it's not a normal database object).
So the other solution is to add the users to the securityadmin role but then explicitly deny alter any login (best done with a custom server role in 2012+ but otherwise just manually in 2008). I tested this out and it works, I'm not able to alter any logins or increase my own permissions, I also did a check of what's reported from fn_my_permissions(null, null) and it shows minimal permissions like I'd expect.
