Hello again,

I need to get the following information:

- Space Allocated from each database,
- Space Used and from each database and
- Space Free from each database in one instance and Total Space Used on that instance.

Can you send me one Query/Stored Procedure that give me all this output.
I need to make one report with all this information.

I know that with sp_spaceused i get this information but i need to get this information for all databases in one cursor or somethin like this.

Thanks and regards,
JMSM ;)

There is an undocumented system procedure that executes any T-SQL query in all databases.

EXECUTE sp_MSforeachdb 'EXECUTE sp_spaceused'

Hello,

Thanks for the information you send me.
But what i need is to get all this information in one table, so i need to insert this info in one temporary table to execute one procedure that send this information in one row for each table.

Thanks and regards,
JMSM ;)

Sorry,

I think that you'll not understand the info that i post before.
I need to make one report that gives this information in one row for each database in one instance.

Thanks and regards

I have a script that gets most of what you want, together with a few other bits of info.

It's a bit messy as it has evolved over time, so you could remove a few superfluous bits if you want.

create table #ls (name varchar(255), LogSize real, LogSpaceUsed real, Status int) 

insert #ls exec ('dbcc sqlperf(logspace)')

declare @name varchar(255), @sql varchar(1000);

select d.name, DATABASEPROPERTYEX(d.name, 'Status') Status,
case when DATABASEPROPERTYEX(d.name, 'IsAutoCreateStatistics') = 1
then 'ON' else 'OFF' end AutoCreateStatistics,
case when DATABASEPROPERTYEX(d.name, 'IsAutoUpdateStatistics') = 1
then 'ON' else 'OFF' end AutoUpdateStatistics,
case when DATABASEPROPERTYEX(d.name, 'IsAutoShrink') = 1
then 'ON' else 'OFF' end AutoShrink,
case when DATABASEPROPERTYEX(d.name, 'IsAutoClose') = 1
then 'ON' else 'OFF' end AutoClose,
DATABASEPROPERTYEX(d.name, 'Collation') Collation,
DATABASEPROPERTYEX(d.name, 'Updateability') Updateability,
DATABASEPROPERTYEX(d.name, 'UserAccess') UserAccess,
replace(page_verify_option_desc, '_', ' ') PageVerifyOption,
d.compatibility_level CompatibilityLevel,
DATABASEPROPERTYEX(d.name, 'Recovery') RecoveryModel,
convert(bigint, 0) as Size, convert(bigint, 0) Used,
case when sum(NumberReads+NumberWrites) > 0
then sum(IoStallMS)/sum(NumberReads+NumberWrites) else -1 end AvgIoMs,
ls.LogSize, ls.LogSpaceUsed,
b.backup_start_date LastBackup
into #dbs1
from master.sys.databases as d
left join msdb..backupset b
on d.name = b.database_name and b.backup_start_date = (
select max(backup_start_date)
from msdb..backupset
where database_name = b.database_name
and type = 'D')
left join ::fn_virtualfilestats(-1, -1) as vfs
on d.database_id = vfs.DbId
join #ls as ls
on d.name = ls.name
group by d.name, DATABASEPROPERTYEX(d.name, 'Status'),
case when DATABASEPROPERTYEX(d.name, 'IsAutoCreateStatistics') = 1
then 'ON' else 'OFF' end,
case when DATABASEPROPERTYEX(d.name, 'IsAutoUpdateStatistics') = 1
then 'ON' else 'OFF' end,
case when DATABASEPROPERTYEX(d.name, 'IsAutoShrink') = 1
then 'ON' else 'OFF' end,
case when DATABASEPROPERTYEX(d.name, 'IsAutoClose') = 1
then 'ON' else 'OFF' end,
DATABASEPROPERTYEX(d.name, 'Collation'),
DATABASEPROPERTYEX(d.name, 'Updateability'),
DATABASEPROPERTYEX(d.name, 'UserAccess'),
page_verify_option_desc,
d.compatibility_level,
DATABASEPROPERTYEX(d.name, 'Recovery'),
ls.LogSize, ls.LogSpaceUsed, b.backup_start_date;

create table #dbsize1 (
fileid int,
filegroup int,
TotalExtents bigint,
UsedExtents bigint,
dbname varchar(255),
FileName varchar(255));

declare c1 cursor for select name from #dbs1;
open c1;

fetch next from c1 into @name;
while @@fetch_status = 0
begin
set @sql = 'use [' + @name + ']; DBCC SHOWFILESTATS WITH NO_INFOMSGS;'
insert #dbsize1 exec(@sql);
update #dbs1
set Size = (select sum(TotalExtents) / 16 from #dbsize1),
Used = (select sum(UsedExtents) / 16 from #dbsize1)
where name = @name;
truncate table #dbsize1;
fetch next from c1 into @name;
end;
close c1;
deallocate c1;

select * from #dbs1
order by name;

drop table #dbsize1;
drop table #dbs1;
drop table #ls;

Hope this works for you:

Create TABLE #db_file_information(
fileid integer
, theFileGroup integer
, Total_Extents integer
, Used_Extents integer
, db varchar(30)
, file_Path_name varchar(300))

-- Get the size of the datafiles

insert into #db_file_information
( fileid
, theFileGroup
, Total_Extents
, Used_Extents
, db
, file_Path_name )
exec sp_MSForEachDB 'Use ?; DBCC showfilestats'

-- add two columns to the temp table

alter table #db_file_information add PercentFree as
((Total_Extents-Used_Extents)*100/(Total_extents))

alter table #db_file_information add TotalSpace_MB as
((Total_Extents*64)/1024)

alter table #db_file_information add UsedSpace_MB as
((Used_Extents*64)/1024)

alter table #db_file_information add FreeSpace_MB as
((Total_Extents*64)/1024-(Used_Extents*64)/1024)

select * from #db_file_information

drop table #db_file_information
