MSSQL script for calculating database size

Description:
Following  script will help us to find database size with numbers of parameters like Dbname, dbstatus, Recovery_Model, DBsize, file_Size_MB, Space_Used_MB, Free_Space_MB, Log_File_Size_MB, log_Space_Used_MB, log_Free_Space_MB, DB_Freespace.

Script:

if exists (select * from tempdb.sys.all_objects where name like '%#dbsize%')
drop table #dbsize
create table #dbsize
(Dbname varchar(30),dbstatus varchar(20),Recovery_Model varchar(10) default ('NA'), file_Size_MB decimal(20,2)default (0),Space_Used_MB decimal(20,2)default (0),Free_Space_MB decimal(20,2) default (0))
go

insert into #dbsize(Dbname,dbstatus,Recovery_Model,file_Size_MB,Space_Used_MB,Free_Space_MB)
exec sp_msforeachdb
'use [?];
select DB_NAME() AS DbName,
CONVERT(varchar(20),DatabasePropertyEx(''?'',''Status'')) ,
CONVERT(varchar(20),DatabasePropertyEx(''?'',''Recovery'')),
sum(size)/128.0 AS File_Size_MB,
sum(CAST(FILEPROPERTY(name, ''SpaceUsed'') AS INT))/128.0 as Space_Used_MB,
SUM( size)/128.0 - sum(CAST(FILEPROPERTY(name,''SpaceUsed'') AS INT))/128.0 AS Free_Space_MB
from sys.database_files  where type=0 group by type'
go

---------------log size---------------
if exists (select * from tempdb.sys.all_objects where name like '#logsize%')
drop table #logsize
create table #logsize
(Dbname varchar(30), Log_File_Size_MB decimal(20,2)default (0),log_Space_Used_MB decimal(20,2)default (0),log_Free_Space_MB decimal(20,2)default (0))

go

---------------database free size---------------

---------------This will show you the size of data and logs for every database----------
if exists (select * from tempdb.sys.all_objects where name like '%#alldbstate%')
drop table #alldbstate
create table #alldbstate
(dbname varchar(25),
DBstatus varchar(25),
R_model Varchar(20))

--select * from sys.master_files

insert into #alldbstate (dbname,DBstatus,R_model)
select name,CONVERT(varchar(20),DATABASEPROPERTYEX(name,'status')),recovery_model_desc from sys.databases
--select * from #dbsize

insert into #dbsize(Dbname,dbstatus,Recovery_Model)
select dbname,dbstatus,R_model from #alldbstate where DBstatus <> 'online'

insert into #logsize(Dbname)
select dbname from #alldbstate where DBstatus <> 'online'

insert into #dbfreesize(name)
select dbname from #alldbstate where DBstatus <> 'online'

select

d.Dbname,d.dbstatus,d.Recovery_Model,
(file_size_mb + log_file_size_mb) as DBsize,
d.file_Size_MB,d.Space_Used_MB,d.Free_Space_MB,
l.Log_File_Size_MB,log_Space_Used_MB,l.log_Free_Space_MB,fs.Freespace as DB_Freespace
from #dbsize d join #logsize l
on d.Dbname=l.Dbname join #dbfreesize fs
on d.Dbname=fs.name
order by Dbname
