Getting the Disk Usage Statistics for all Tables in a Database

Getting the Disk Usage Statistics for all Tables in a Database

I know, there are standard reports and other GUI tools for doing this task for SQL Server 2005 or later but what about when you need to extract such information from a SQL Server 2000 instance or when you just want to write some code? 🙂

The undocumented stored procedure sp_msforeachtable is here to help you (along with the stored procedure sp_spaceused)!

Here’s how:

–Select the database to be scanned for table disk usage

–Create temporary table 1 – Sizes will be in strings/KB
create table #tmpSizes(
[name] nvarchar(200),
[rows] varchar(50),
reserved varchar(50),
data varchar(50),
index_size varchar(50),
unused varchar(50)

–Create temporary table 1 – Sizes will be in KB
create table #tmpSizesFinalKB(
[name] nvarchar(200),
[rows] int,
reserved int,
data int,
index_size int,
unused int

–Get the disk usage per table and store in temp table 1
EXEC sp_MSforeachtable @command1=”sp_spaceused ‘?'”

–Indirect casting and copying of the information in temp table 2
–This is only when you want to store the disk usage statistics
–in a form that allows sorting operations etc.  
insert into #tmpSizesFinalKB
from #tmpSizes

–Access the disk usage results (in KB)
select * 
from #tmpSizesFinalKB
order by reserved desc

Now you can easily manipulate the disk usage statistics in temp table #tmpSizesFinalKB in order to represent them in the form you may like!
