To check the sizes of all of your databases, at the mysql> prompt type the following command: Copy SELECT table_schema AS "Database", ROUND(SUM(data_length + index_length) / 1024 / 1024, 2) AS "Size (MB)" FROM information_schema.
Using SQL Server Management StudioIn Object Explorer, connect to an instance of SQL Server and then expand that instance. Expand Databases. Right-click a database, point to Reports, point to Standard Reports, and then select Disk Usage.
sp_spaceused
sp_helpdb
no looping needed, unlike sp_spaceused.
According to SQL2000 help, sp_spaceused includes data and indexes.
This script should do:
CREATE TABLE #t (name SYSNAME, rows CHAR(11), reserved VARCHAR(18),
data VARCHAR(18), index_size VARCHAR(18), unused VARCHAR(18))
EXEC sp_msforeachtable 'INSERT INTO #t EXEC sp_spaceused ''?'''
-- SELECT * FROM #t ORDER BY name
-- SELECT name, CONVERT(INT, SUBSTRING(data, 1, LEN(data)-3)) FROM #t ORDER BY name
SELECT SUM(CONVERT(INT, SUBSTRING(data, 1, LEN(data)-3))) FROM #t
DROP TABLE #t
In SQL Management Studio, right-click on a database and select "Properties" from the context menu. Look at the "Size" figure.
The best solution is maybe to calculate the size of each database file, using the sys.sysfiles view, considering a size of 8 KB for each page, as follows:
USE [myDatabase]
GO
SELECT
[size] * 8
, [filename]
FROM sysfiles
The [field] column represents the size of the file, in pages (MSDN Reference to sysfiles).
You would see there will be at least two files (MDF and LDF): the sum of these files will give you the correct size of the entire database...
I always liked going after it directly:
SELECT
DB_NAME( dbid ) AS DatabaseName,
CAST( ( SUM( size ) * 8 ) / ( 1024.0 * 1024.0 ) AS decimal( 10, 2 ) ) AS DbSizeGb
FROM
sys.sysaltfiles
GROUP BY
DB_NAME( dbid )
You could use this old fashioned one as well...
