Basic: what's the size on disk of my MS SQL Server DB?
More: can I quickly see where the data is? i.e. which tables, logs, etc

What version of SQL? – SQLChicken May 28 '09 at 12:35
this is a programatic question, show be in StackOverflow! read: – balexandre May 28 '09 at 13:01
I disagree. It's fundamentally a sysadmin question. Why do programmers care if the server runs out of disk space? – Nick Kavadias May 28 '09 at 13:11
I agree with Nick. It's a either/or question. DBA questions definitely belong here. – squillman May 28 '09 at 13:44
It's both: programmers care about handling the exception if the DB runs out of usable space; sysadmins care for obvious reasons. :) – JYelton May 10 '11 at 20:24

You'll probably want to start with the sp_spaceused command.

For example:

sp_spaceused Returns information about the total size of the database

sp_spaceused 'MyTable' Returns information about the size of MyTable

Read the docs for all the things you can get information about. You can also use the sp_msforeachtable command to run sp_spaceused against all tables at once.

Edit: Be aware the command sometimes returns multiple datasets, each set containing a different chunk of stats.

Just to add a note, sp_spaceused returns the number of 8KB pages the database files occupy. – Dario Solera May 28 '09 at 12:46
If your db is 2000 then you might need to run DBCC UPDATEUSAGE to get the right numbers in here. Should always be correct in 2005 – Nick Kavadias May 28 '09 at 13:02

The easiest way (no typing!): In SQL 2005/8 from Management Studio, right click the database, select Reports, Standard Reports, Disk Usage (also By Top Tables, Table and Partition).

This script loops through all of the tables in the current database and shows how much space each one takes up for data, indexes, and unused space:

You can see the physical files in sys.database_files. This has the path to the file and the size (in blocks IIRC).

sp_spaceused will show you how much space an individual object takes up.

Run Start\ Programs\ Microsoft SQL Server\ Enterprise Manager. Open Database sheet, in property %databasename% you can see location Data filrs & Transaction files.

Or if it's SQL Server 2005, 2008, etc, open SQL Management Studio, right click the database, select properties and then click the second item on the left tab, files. However this will only return the overall file size - which you could see by just looking in the folder where the data and log file are stored. – David May 28 '09 at 12:43

run this to get the size per table:

This is a query/view that gets all of this info, and more, without any "evil" cursors or loops. ;-)

    vwTableInfo - Table Information View

 This view display space and storage information for every table in a
SQL Server 2005 database.
Columns are:
    Owner		may be different from Schema)
    Columns		count of the max number of columns ever used)
    HasClusIdx	1 if table has a clustered index, 0 otherwise
    IndexKB		space used by the table's indexes
    DataKB		space used by the table's data

There are several descriptions of how to do it from the GUI.

Real DBA's know: GUI's are for chumps.


Returns a recordset of all of the file names, locations, space on disk, and type.

You can also retrieve the file names from each databases's sysfiles table.
