As a DBA for a large corporation, I manage literally hundreds of databases. In order to help keep track of all the databases and log files, I needed a way to quickly gather an inventory of all databases located on each sql named instance, so I came up with this simple little script that also includes a filesize in megabytes column:
sysdatabases.name AS 'db_name'
, (select 'file_type' =
WHEN sysaltfiles.groupid = 1 THEN 'data'
WHEN sysaltfiles.groupid = 0 THEN 'log'
END) as 'file_type'
, sysaltfiles.name AS 'file_name'
, (sysaltfiles.size * 8 / 1024) AS 'file_size(MB)' -- file size in MB
sysdatabases.dbid NOT IN ('1','2','3','4')
Run this script in the Master database and it will output a database list that you can export to a spreadsheet for reporting or futher analysis. If anyone knows a better way to do this or some enhancement suggestions to include additional useful information, let me know.
