Fileproperty for each database

Question

Hi,
i want to learn mydatabases file sizes(database file and log file)
select * from sys.sysfiles gives that,but it is running for only one database.
i want to learn that for each database,is it possible?
Thanks

Answer 1

it's giving that for only one database which is working on.
To run this script for each database on the server, you'll need to set the database context for each database so that FILEPROPERTY can be used.  Your options are:
Run a script to generate another with a USE statement for each database (Fabrizzio's suggestion)
Run the script using the undocumented sp_MSforeachdb procedure with your script as a parameter (Prasad's suggestion)
Write a script with a cursor over sys.databases and execute your script with a USE statement before each execution:
DECLARE
@SqlStatement nvarchar(MAX)
,@DatabaseName sysname;
IF OBJECT_ID(N'tempdb..#DatabaseSpace') IS NOT NULL
DROP TABLE #DatabaseSpace;
CREATE TABLE #DatabaseSpace(
DATABASE_NAME sysname
,LOGICAL_NAME sysname
,FILE_SIZE_MB decimal(12, 2)
,SPACE_USED_MB decimal(12, 2)
,FREE_SPACE_MB decimal(12, 2)
,FILE_NAME sysname
DECLARE DatabaseList CURSOR LOCAL FAST_FORWARD FOR
SELECT name FROM sys.databases;
OPEN DatabaseList;
WHILE 1 = 1
BEGIN
FETCH NEXT FROM DatabaseList INTO @DatabaseName;
IF @@FETCH_STATUS = -1 BREAK;
SET @SqlStatement = N'USE '
+ QUOTENAME(@DatabaseName)
+ CHAR(13)+ CHAR(10)
+ N'INSERT INTO #DatabaseSpace
SELECT
[DATABASE_NAME] = DB_NAME()
,[LOGICAL_NAME] = f.name
,[FILE_SIZE_MB] = CONVERT(decimal(12,2),round(f.size/128.000,2))
,[SPACE_USED_MB] = CONVERT(decimal(12,2),round(fileproperty(f.name,''SpaceUsed'')/128.000,2))
,[FREE_SPACE_MB] = CONVERT(decimal(12,2),round((f.size-fileproperty(f.name,''SpaceUsed''))/128.000,2))
,[FILENAME] = f.name
FROM sys.database_files f;';
EXECUTE(@SqlStatement);
END
CLOSE DatabaseList;
DEALLOCATE DatabaseList;
SELECT * FROM #DatabaseSpace;
DROP TABLE #DatabaseSpace;;
GO
