How to find the total tablespace usage in SQL Server 2008? - sql

Question

In SQL-server 2008, How would I find (through an SQL query), the percentage of tablespace usage for a particular instance(or all instances) of a SQL Server(2008 R2)?
Also, what is the best way (query) to get the list of all the Named Instances of a SQL Server?

Answer 1

is this what you need:
EXEC sp_spaceused null, false
result:
database_name database_size unallocated space
--------------- ------------------ ------------------
DATABASE_NAME 220.25 MB 69.92 MB
reserved data index_size unused

Use the script:
set nocount on
declare #indexes table(
QualifiedName nvarchar(512),
IndexId int,
FGName nvarchar(128),
Type nvarchar(50),
NumKeys int,
IndexKB numeric(28,0),
UsedKB numeric(28,0),
FreeKB numeric(28,0),
Rows numeric(28,0),
RowModCtr numeric(28,0),
OrigFillFactor int,
tableid bigint
)
insert into #indexes
select
db_name() + '.' + isnull(su.name,'<unknown-user>') + '.' + so.name + '.' + isnull(i.name,'<Heap>') QualifiedName,
i.index_id IndexId,
(select isnull(name,'') from sys.filegroups where data_space_id = i.data_space_id) FGName,
case
when so.type = 'V' then 'Indexed View: '
else ''
end +
case
when i.index_id = 0 then 'Heap'
when i.index_id = 1 then 'Clustered'
else 'Non Clustered'
end Type,
0 NumKeys,
a.used_pages* 8 IndexKB,
CASE
When a.type <> 1 Then a.used_pages * 8
When p.index_id < 2 Then a.data_pages * 8
Else 0
END UsedKB,
(a.total_pages-a.used_pages)* 8 FreeKB,
p.rows Rows,
0 RowModCtr,
i.fill_factor OrigFillFactor,
convert(bigint,db_id()) * power(convert(bigint,2),48) + convert(bigint,su.schema_id) * power(convert(bigint,2),32) + so.object_id tableid
from
sys.objects so with (readpast)
inner join sys.schemas su with (readpast) on su.schema_id = so.schema_id
inner join sys.indexes i with (readpast) on so.object_id = i.object_id
inner join sys.partitions p with (readpast) ON i.object_id = p.object_id and i.index_id = p.index_id
inner join sys.allocation_units a with (readpast) on p.partition_id = a.container_id
where
(so.type = 'U') and a.type_Desc = 'IN_ROW_DATA'
and isnull(INDEXPROPERTY(i.object_id, i.name, 'IsStatistics'),0) = 0
and isnull(INDEXPROPERTY(i.object_id, i.name, 'IsAutoStatistics'),0) = 0
and isnull(INDEXPROPERTY(i.object_id, i.name, 'IsHypothetical'),0) = 0
order by
IndexKB desc
select
i.QualifiedName,
i.IndexId,
i.FGName,

i.NumKeys,
i.IndexKB,
(i.UsedKB - isnull(t.s_UsedKB,0)) UsedKB,
(i.FreeKB - isnull(t.s_FreeKB,0)) FreeKB,
i.Rows,
i.RowModCtr,
i.OrigFillFactor
from
#indexes i
left outer join (
select tableid, sum(UsedKB) s_UsedKB, sum(FreeKB) s_FreeKB
from #indexes
where IndexId > 1
group by tableid
) t on t.tableid = i.tableid
and i.IndexId <= 1
order by
IndexKB desc
