SQL Server 2008 :: Renaming Logical File Names
Apr 30, 2015
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].

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?

I have a SQL Server 2008 R2 Cluster. I have moved a file to another drive by adding a new file on the drive, doing a shrinkfile with emptyfile. I have removed the old file and when I try to rename the new file to the old files old name, I get an error.
ALTER DATABASE mydb REMOVE FILE myfilename
Msg 5009, Level 16, State 9, Line 1
One or more files listed in the statement could not be found or could not be initialized.
ALTER DATABASE mydb
modify FILE ( NAME = temp_filename
, NEWNAME = myfilename
)
Msg 1828, Level 16, State 3, Line 4
The logical file name "myfilename" is already in use. Choose a different name.
I have completed a failover, thinking the name was being held in cache. I've also renamed to something completely different then tried to rename to the old filename.

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!

If I run an ALTER DATABASE command that renames the Logical file name of a database, will I run into any unseen consequences in terms of day to day use of the database?

I'm working on creating a new version of an existing table. I want to keep the old table around, only with a different name. In looking this up I found there's a system routine named sp_rename, which looks like it will work fine.However in thinking about this I realized that the foreign key constraints defined on the table (there's 3 of them) are likely to not be renamed, correct?
If I'm correct, then I suppose I could rename the table, then drop the 3 foreign key constraints, and create them new using different names for those foreign key constraints.

I got a table which gets populated by stor proc where we pivot the Sum(Balance of mortgage) by YYYYMM for the whole duration of the loan term.
I have a requirement to rename the column header where the previous month end balance period be renamed to P0.
if we run the report today, then the balance as at 31/09 should show under column P0 which now shows under 201509 and then P0 keeps shifting with each month run.
How do I dynamically rename the column headers.

The database has approx. 2500 temporary tables. The temp tables match a pattern such as APTMP... I tried deleting the tables in SSMS with the statement, Delete from Information_Schema.tables where substring(table_name,1,5) = 'APTMP' This returns the error message"Ad hoc updates to system catalogs are not allowed".
What is the correct way to delete a group of tables whose name match a pattern from within SSMS?

I'm copying files to a folder with the naming convention as follows in the source folder:
CM_ABC_MY_TEST.txt
In the destination folder, this filename needs to appear as:
CM_XYZ_MY_TEST.txt
In my File System Task, I'm pretty sure I'm going to need an expression with a replace, substring, etc. But am having a hard time nailing down the exact syntax.

I am designing a package to export staging tables into a flat file.The names of the tables will be: TableAStaging_YYYYMM and TableBStaging_YYYYMM. As you can see the names of the tables will be changing each month.
The flat files will have similar naming: C:MyPathFlatFileTableAStaging__YYYYMM and C:MyPathFlatFileTableAStaging__YYYYMM.I want to run the package as an sql job in two steps, one for each table.I need to dynamically pass the table names and file names (together with the path) to the IS package.

Hi All,
We have a SSIS package which is accessing a remote Windows file share location.
The package first moves the file from folder-1 to folder-2 and also renames the file during this process.
Then the package reads the file (using a flat file connection FF_SRC) from folder-2 and renames it again after processing it successfully.
The permissions given to the user executing the package on folder-2 are: Read+Write+Modify+List folder contents.
We are facing an error:
Code SnippetFile or directory "Z:folder-2XYZ.txt" represented by connection "FF_SRC" does not exist.
We are getting the above error when the SSIS package is trying to rename the file the second time in folder-2.
However, the file exists in folder-2.
The OS is Windows 2000 Server SP4.
Any ideas why this could be happening and how it could be resolved?
Best Regards,
Avnip

I'm having trouble working this out in SSIS. I am trying to use a File System task to rename a file using an expression so that file.zip will be renamed to filemmyy.zip at the end of every month (for instance this month would be file0506.zip).
I am using the destination expression variable. But I'm not sure what to put for DestinationConnection. It seems to want a file name, but the file name is going to be variable, so I'm not sure what to put.
Any ideas?

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.

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.

I have had a go at using a package with a script to rename and move a file and it works well by using a script task in a package with source and destination variables. See script at bottom
But in my scenario the file thst comes in every day will have a slightly different name. It will be called "System_UT_INCR_BOOKINGHEADER_20080228000000.TXT"
On the 28th Feb. The date part of the title changes everyday.
SO i need to adjust my "Source" variable which is currently just a string with a value of "C:DatafilesimportsSystem_UT_INCR_BOOKINGHEADER_20080228000000.TXT" So it will only ever look for that exact file name

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 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!

Hi,
I am using a DTS package to extract data from a table and export it to an excel file. This task needs to run on a weekly basis and the filename should contain the date the file was created. I have sucessfully used the activex scropt below to rename .txt files but when I try to use it for Excel files it always defaults to the default filename I specified in the destination file properties. Can anyone show me how to do this for Excel files?
'**********************************************************************
' Visual Basic ActiveX Script
'************************************************************************
Option Explicit
Function Main()
Dim sFilename, oPkg, oConn
Dim sYear, sMonth, sDay
If Month(Now) > 10 Then sMonth = Month(Now) Else sMonth = "0" & Month(Now)
If Day(Now) > 10 Then sDay = Day(Now) Else sDay = "0" & Day(Now)
sFilename = "\servernameD$Daily ReportsFlagcodes " & sDay & sMonth & Year(Now) & ".xls"
Set oPkg = DTSGlobalVariables.Parent
Set oConn = oPkg.Connections(2)
oConn.DataSource = sFileName
Set oConn = Nothing
Set oPkg = Nothing

Historically I've always written a VB script to copy a file from a sharepoint library. I don't like this method because I have to input a username & password in the script and maintain a config file.
Yesterday I was playing around with using a file system task. The sharepoint file has a UNC path so why not? I created a simple test package with a single file system task that copies the sharepoint file (addressed via UNC) to another network location. Package runs fine locally.
I try running on our utility server but am getting a "The file name [SHAREPOINT UNC PATH] specified in the connection was not valid" error. Package is running with a proxy on the server and the proxy account has the same permissions to the sharepoint site (so far as I can tell) as me.
