Hi,

every thing that you need to know is writing in the script details.
but for you i'll write it again.
this stored procedure move the LDF or MDF files to a new location.
the syntax to use it is after that you run the script that create the stored procedure is
example MDF: exec MoveAllDatabaseFile 'MDF','C:\NewMDFLocation\'
example LDF: exec MoveAllDatabaseFile 'LDF','C:\NewMDFLocation\'
after that you stop SQL Server Services,move those MDF or LDF files that you just run the script on them and then start the SQL Server Services back.

The Script

--Move All MDF - LDF Files to a new location
--write by Avi Grinberg
create procedure MoveAllDatabaseFile
@FileType char (3),@fullpath varchar(500)
as
if @FileType not in ('MDF','LDF')
begin
Select '@FileType must be MDF or LDF and @fullpath should be like N''C:\DatabaseFiles\'' the script was terminated' as
'ERROR'
select 'example of right syntax - exec MoveAllDatabaseFile ''MDF'',N''C:\DatabaseFiles\''' as 'Example Script'
return
end
declare @dbname as varchar (100)
declare @dbfilename as varchar (100)
declare @runalter as varchar(500)
--Case LDF
if @FileType = 'LDF'
begin
DECLARE CRS_db CURSOR LOCAL FAST_FORWARD
FOR
select sysdb.name as 'DBName',masterfiles.name as 'FileName'
from sys.master_files masterfiles,sys.sysdatabases sysdb
where masterfiles.database_id = sysdb.dbid
and masterfiles.type_desc = 'LOG' and masterfiles.database_id > 4 --not take system DB's
end
--Case MDF
else
begin
DECLARE CRS_db CURSOR LOCAL FAST_FORWARD
FOR
select sysdb.name as 'DBName',masterfiles.name as 'FileName'
from sys.master_files masterfiles,sys.sysdatabases sysdb
where masterfiles.database_id = sysdb.dbid
and masterfiles.type_desc = 'ROWS' and masterfiles.database_id > 4 --not take system DB's
end
--Start execute MDF or LDF
OPEN CRS_db
FETCH NEXT FROM CRS_db INTO @dbname,@dbfilename

WHILE @@FETCH_STATUS = 0
BEGIN

Set @runalter = 'Alter database ' + @dbname + ' modify file (name = ' + @dbfilename + ' , filename = N'''+ @fullpath +
@dbfilename + '.' + @FileType + ''')'

exec(@runalter)

FETCH NEXT FROM CRS_db INTO @dbname,@dbfilename
END
CLOSE CRS_db
DEALLOCATE CRS_db

Followed the directions but this did not work for me. I had to drop every db and use sp_attach_db after moving the mdf and ldf files. Oh well.....

you can use this improved script.

--This script create a store procedure that Move All MDF - LDF Files
--Wrote by Avi Grinberg
create procedure MoveAllDatabaseFile
@FileType char (3),@fullpath varchar(100)
as
if @FileType not in ('MDF','LDF','mdf','ldf')
begin
print '@FileType must be MDF or LDF (or lower case) and @fullpath should be like N''C:\DatabaseFiles\'' the script was terminated!.'
print 'example of right syntax - exec MoveAllDatabaseFile ''MDF'',N''C:\DatabaseFiles\'''
return
end
if @fullpath not like '%\'
begin
print 'The @fullpath must end with a ''\'' ,this script is terminated!. '
return
end
declare @dbname as varchar (100)
declare @LogicalFileName as varchar (100)
declare @PhysicalFileName as varchar (100)
declare @runalter as varchar(500)
--Case LDF
if @FileType = 'LDF' or @FileType = 'ldf'
begin
DECLARE CRS_db CURSOR LOCAL FAST_FORWARD
FOR
select sysdb.name as 'DBName',masterfiles.name as 'LogicalFileName',substring(right(physical_name,charindex('\',reverse(physical_name))),2,100) as 'PhysicalFileName'
from sys.master_files masterfiles,sys.sysdatabases sysdb
where masterfiles.database_id = sysdb.dbid
and masterfiles.type_desc = 'LOG' and masterfiles.database_id > 4
end
--Case MDF
else
begin
DECLARE CRS_db CURSOR LOCAL FAST_FORWARD
FOR
select sysdb.name as 'DBName',masterfiles.name as 'LogicalFileName',substring(right(physical_name,charindex('\',reverse(physical_name))),2,100) as 'PhysicalFileName'
from sys.master_files masterfiles,sys.sysdatabases sysdb
where masterfiles.database_id = sysdb.dbid
and masterfiles.type_desc = 'ROWS' and masterfiles.database_id > 4 --not take system DB's
end
--Start execute MDF or LDF
OPEN CRS_db
FETCH NEXT FROM CRS_db INTO @dbname,@LogicalFileName,@PhysicalFileName

WHILE @@FETCH_STATUS = 0
BEGIN

Set @runalter = 'Alter database ' + @dbname + ' modify file (name = ' + @LogicalFileName + ' , filename = N'''+ @fullpath + @PhysicalFileName + ''')'

select (@runalter)

FETCH NEXT FROM CRS_db INTO @dbname,@LogicalFileName,@PhysicalFileName
END
CLOSE CRS_db
DEALLOCATE CRS_db

Avi,

just want to say thanks for posting the script, I have over 300 databases to move and this script will be most useful. ( I have done a successful trial run on a test bed server)

Only change I would make is use 'print (@runalter)' rather than 'select (@runalter)' so only the commands you actually want are reversed engineered out, also all the databases could be offlined, files moved, then bought on-line again if you want to avoid a service restart.

cheers

george
