Find the size of every database

Find the size of every database

Madhusudan Naidu Gundapaneni

You can find out how much space a database is occupying on the hard disk by using the sp_spaceused function. However, if you want to find all database sizes at once, you have to use sp_spaceused for all databases. It takes some time to write all those T-SQL statments. This handy script will find the size of every database in SQL Server 2000 without using the sp_spaceused function. It will save you time as well as the server's time.

CREATE PROCEDURE Usp_FindAllDBSizes
AS
SET NOCOUNT ON
DECLARE @counter SMALLINT
DECLARE @counter1 SMALLINT
DECLARE @dbname VARCHAR(100)
DECLARE @size INT
DECLARE @size1 DECIMAL(15,2)
SET @size1=0.0

SELECT @counter=MAX(dbid) FROM master..sysdatabases
IF EXISTS(SELECT name FROM sysobjects WHERE name='sizeinfo')
DROP TABLE sizeinfo
CREATE TABLE sizeinfo(fileid SMALLINT, filesize DECIMAL(15,2), filename VARCHAR(1000))
WHILE @counter >
