Same Logical File Name For Two DB.
Jul 5, 2000
Hi everyone,
I have a database (xyz) one Machine A. On the same machine I want to create a copy of the (xyz)database with different name(xyz_1). When I restore with move option it will restore but the thing is logical file names of xyz and xyz_1 are same. I know I can change these file names by manupulating the system table.
My question is If I didn't change the logical file names of database xyz_1(new). Is there any problems or issues may arise.
Thank you,
Dindu.

In the database properties screen, there are four tabs: General, Transaction Log, Options, Permissions. In the General Tab, it lists four columns: File name, Location, Space Allocated, File Group.
The string in the File name column has a value such as MY_DATABASE_DAT, whereas the Location column has a value like D:mssql7dataMY_DATABASE.MDF.
The Location value is clearly the Windows file name. The "File name" (which I have seen called the "logical file") is a mystery to me. What is it used for? How can it be changed? Is there a problem if two different databases have the same "logical file" name?
(For example, if you do sp_detach_db, copy the file to another place and then sp_attach_db the new file to another database name, you have two different databases with the same "logical file" name.)
Much thanks to anyone who can shed light on this.

I cannot find the answer to this: how do you update the logical file name for a database? Restore database "Alpha" over "Beta" specifying WITH MOVE parms allows "Alpha"'s physical files to overlay "Beta"'s, but now "Beta"'s logical file names are "Alpha_Data" and "Alpha_Log".
Updating sysfiles directly gives back a 270; "Get outta here!"
Can this not be done?

Hi
Every one
One thing i found out that my 2 databases in server A
Has same logical file name .
I have try to change the name but it is not allowing me to change.
I had refer BOL it says that we should have unique logical file name in a server for each database.
Question i have is does it going harm me i don't know this
if any one u know please suggest me.
Problem I already started getting is I do backup 5 small databases of 10 to 20 mb in one tape only. The 2 database which has same logical file name out
of which one is getting copied & another is not ,All other database it backup
perfecly.
But at the same time in a hard disk if i take backup of this database in a same device it works perfecly so i don't understand where the problem is
If any has any idea please suggest me
Thanks

I'm moving a database (XYZtest) from the test server to the production server via sp_detach/sp_attach. I want the logical file names to be XYZ_data, rather than XYZtest_data, etc. I can easily rename the disk files, but how do I rename the logical file names?
Thanks,
Al

Is there a way to rename the logical file for a database. For example, if I am moving a development database into production, I can use backup - but the backup takes the logical file names of the database and puts it into my production server. Now I have a production database with "dev_data1" for a logical file.....Can I change that name....?
Thanks!

Hi all -
Quick question... I want to move all my non-clustered indexes to their own seperate drive array. How would I accomplish this?
Do I just add the filename at the end of the statement like you do in Oracle? (EXAMPLE: CREATE INDEX IDX_Cls_Code on dbo.Class(Code) on secondary.ndf)
If this isn't correct, can someone please post the correct syntax?
Thanks!

Is there a way to rename the logical file names? I'm not talkingspecifically about the physical files, because those can be changedduring a restore, but the values immediately to the left of those inEnterprise Manager such as DBName_Data and DBName_log. EnterpriseManager lets me change them during a restore, but when I do it gives anerror. Any ideas?

Is there any danger with renaming the LOGICAL file names behind the database?
There are a bunch of databases that were restored copies and all of them have the same logical database file name. I'm trying to get some growth data so I want the logical files to be different (prefer them to match the actual database name) so I can more easily identify them.
For instance:
database_id name type_desc name physical_name
1 DLMdb1 ROWS DLMDB1 D:dlmdb1.mdf
1 DLMdb1 LOG DLMDB1_log E:dlmdb1.ldf
2 DLMdb2 ROWS DLMDB1 D:dlmdb2.mdf
2 DLMdb2 LOG DLMDB1_log E:dlmdb2.ldf
3 DLMdb3 ROWS DLMDB1 D:dlmdb3.mdf
3 DLMdb3 LOG DLMDB1_log E:dlmdb3.ldf
Am I safe to rename the logical names? I can't think of anything that references those logical file names that I would be breaking [backups, applications].

What's is the between backing up a database to a file and a logical backup device?
If I point the logical backup device to a file on the filesystem, it's same as backing up to a file? isn't?

Hi all
We generally modify the logical name of a data file or log file from the vendor defined to our standard name. Is there any impact that you know about this? If you have 2 seperate database and accidently you have 2 same logical name .. I dont' think that will be an issue ... correct?
ALTER DATABASE XXX_UAT
MODIFY FILE (NAME = 'mdd_Data', NEWNAME = 'XXX_UAT_Data')
GO
ALTER DATABASE XXX_UAT
MODIFY FILE (NAME = 'mdd_Log', NEWNAME = 'XXX_UAT_Log')
GO

I have a query. on my search page i have a number of textboxes e.g. title, subtitle, ISBN where users can enter a search string and when they click on a button the data is displayed in the gridview below.
my query seems to be bringing up the right records but with some additional records into the gridview. I have tried the same query within the SQL server management studio and it brings back two records like indicated but within my aspx page it brings back 6 additional records that have no relevance to the query. Im quite baffled as to why this is happening and i have debugged but nothing comes to light.
my code in my aspx page is as follows:
public void BindData(){String _BookID = TxtBookID.Text;String _Title = TxtTitle.Text;String _Subtitle = TxtSubtitle.Text;String _ISBN = TxtISBN.Text;String AuthorFName = TxtForename.Text;String AuthorLName = TxtSurname.Text;
SqlDataAdapter ad = new SqlDataAdapter("SELECT Book_ID, Book_ID_Internal AS [Book Internal ID], Title, Subtitle, ISBN, Edition, Publication_Date AS [Published Date] FROM Book WHERE Book_ID_Internal = '" + _BookID + "' OR Title = '" + _Title + "' OR Subtitle = '" + _Subtitle + "'", conn);DataSet ds = new DataSet();ad.Fill(ds, "Book");if (ds.Tables[0].Rows.Count == 0){//if there are no rows returned-state in the gridds.Tables[0].Rows.Add(ds.Tables[0].NewRow());GridView1.DataSource = ds;GridView1.DataBind();int columncount = GridView1.Rows[0].Cells.Count;GridView1.Rows[0].Cells.Clear();GridView1.Rows[0].Cells.Add(new TableCell());GridView1.Rows[0].Cells[0].ColumnSpan = columncount;GridView1.Rows[0].Cells[0].Font.Italic = true;GridView1.Rows[0].Cells[0].Text = "No Records Found";}else{GridView1.DataSource = ds;GridView1.DataBind();}}
if i input the same query into SQL management studio:
SELECT * FROM Book WHERE Book_ID_Internal = 'ITD 450' OR Title = 'HTML 4.0'
it returns two records which is correct.
Can anyone see where i am going wrong?

The organisation I'm working for has SQL Server 2005 merge replication up and running on 11 servers in 3 different countries.
Ocasionally we experience problems caused by rows in a logical record relationship being replicated between servers in the wrong order, i.e. an attempt is made to insert child rows before the parent. I am not able to reproduce this behaviour on my test servers.
Has anyone else experienced this problem?

Hi All,
I've been asked to trouble shoot an installation where many stored procedures are performing poorly. Upon examination I've found that the queries in these procs consume a large volume of logical IO (table scans etc). I'm trying to show that this could cause poor performance of the stored procedures as well as degredation of the server as a whole - but I cant find any suitable counters in Perfmon.
Anyone help?

I have a view based on few tables okay
I have a query that gives me document details of various revisions
Now i also get the latest rev of those if i use a MAX() in my Query
Now a case where i have say
Docu Numb - Revi - Received Date
Document1 - rev0 - 10/2004
Document1 - rev1 - 11/2004
Document1 - rev2 - 12/2004
Document1 - rev3 - 01/2005
Document1 - rev4 - 02/2005
Document1 - rev5 - 03/2005
Document1 - rev6 - 04/2005
Document1 - rev7 - 05/2005
If i query for latest it gives Document1 - rev7
And if i filter for a month of 12/2004
If i query for latest it should give Document1 - rev2
Now i need to get a filter with latest as rev2,
plus i also need as a indication of actual latest as rev 7
using a query
How do i do that ...
Coz when i use filter for a month and Max then it
does not consider rev7 for that filter and skip the record
and if i try to filter only as per month .. i get a wrong info
as latest rev2 which is not a true info as per database records.
May i possibly get both ... filtered info as per specific month and
also a rev info as what is the latest for a spec document.
Just i need to know is that possible .. in SQl using a query
Any more info needed please mail me on

I'm trying to restore about 70 databases onto a new SQL server andwanted to script the creation and restore. I've done the creation withno problems, but on the restore, the logical names (of the originaldata) are all over the place and were historically wrong.So, when I use the script below... I've had to work out the Logicalname for the data and the log file and alter the script accordingly.Creation------------Create Database MyDatabase ON (NAME = MyDatabase_data, FileName ='D:DatabaseMSSQLDataMyDatabase.mdf') LOG ON (NAME = MyDatabase_log,FileName = 'D:DatabaseMSSQLDataMyDatabase.ldf') COLLATESQL_Latin1_General_CP1_CI_ASRestore-----------RESTORE FILELISTONLYfrom disk ='D:DatabaseMSSQLBACKUP2006-08-07MyDatabase_db_200608072100.BAK'restore database MyDatabasefrom disk ='D:DatabaseMSSQLBACKUP2006-08-07MyDatabase_db_200608072100.BAK'with REPLACE,MOVE 'SomeOtherRubbish_Data' TO'D:DatabaseMSSQLDataMyDatabase.mdf',MOVE 'SomeOtherRubbish_Log' TO'D:DatabaseMSSQLDataMyDatabase.ldf'goWhen I then look at the properties of the database, it shows the oldconvention which I don't want.So, even though I've been neat creating the database, it getsoverwritten with the odl rubbish name. How can I change the logicalname so that I can have a nice and neat naming convention ?Oh, Yes I know I added the collation when creating the database, butthat's another thing that we need to address at some point.Thanks in advance

The many that I have spoken to all are clueless on this one. Thanks in advance for the right solution!
The insert trigger I created works fine (well, nearly fine), except that AFTER the first insert operation (ie second, third etc), it always produces the correct results BUT FOR THE PREVIOUS INSERTED ROW. It is as if there is a latency of one row in the temp table INSERTED.
I would greatly appreciate a 'why', and more importantly, a 'how to fix it' for this problem.
If you need to look at the code, a NOTEPAD file is attached.
Much appreciated
