USE master

CREATE PROC sp_track_db_growth
@dbnameParam sysname = NULL

Purpose: To calulate the file growth percentages for a given database and to show you the rate at which
your databases are growing, so that you can plan ahead for your future storage needs.

Usage: Run this script in the master database to create the stored procedure. Once it is created,
you could run it from any of your user databases. If the first parameter (database name) is
not specified, the procedure will use the current database.

Example 1:
To see the file growth information of the current database:

EXEC sp_track_db_growth

Example 2:
To see the file growth information for pubs database:

EXEC sp_track_db_growth 'pubs'


DECLARE @dbname sysname

/* Work with current database if a database name is not specified */

SET @dbname = COALESCE(@dbnameParam, DB_NAME())

SELECT CONVERT(char, backup_start_date, 111) AS [Date], --yyyy/mm/dd format
CONVERT(char, backup_start_date, 108) AS [Time],
@dbname AS [Database Name], [filegroup_name] AS [Filegroup Name], logical_name AS [Logical Filename],
physical_name AS [Physical Filename], CONVERT(numeric(9,2),file_size/1048576) AS [File Size (MB)],
Growth AS [Growth Percentage (%)]
SELECT b.backup_start_date, a.backup_set_id, a.file_size, a.logical_name, a.[filegroup_name], a.physical_name,
SELECT CONVERT(numeric(5,2),((a.file_size * 100.00)/i1.file_size)-100)
FROM msdb.dbo.backupfile i1
WHERE i1.backup_set_id =
SELECT MAX(i2.backup_set_id)
FROM msdb.dbo.backupfile i2 JOIN msdb.dbo.backupset i3
ON i2.backup_set_id = i3.backup_set_id
WHERE i2.backup_set_id < a.backup_set_id AND
i2.file_type='D' AND
i3.database_name = @dbname AND
i2.logical_name = a.logical_name AND
i2.logical_name = i1.logical_name AND
i3.type = 'D'
i1.file_type = 'D'
) AS Growth
FROM msdb.dbo.backupfile a JOIN msdb.dbo.backupset b
ON a.backup_set_id = b.backup_set_id
WHERE b.database_name = @dbname AND
a.file_type = 'D' AND
b.type = 'D'

) as Derived
WHERE (Growth <> 0.0) OR (Growth IS NULL)
ORDER BY logical_name, [Date]
