如何查找SQL Server 2008中的總表空間使用情況？

Question

在SQL-server 2008中，如何查找（通過SQL查詢）SQL Server（2008 R2）的特定實例（或所有實例）的表空間使用百分比？

此外，獲取SQL Server的所有命名實例列表的最佳方法（查詢）是什麼？

Answer 1

使用腳本：

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.Type, 
    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 

Answer 2

這是你需要的東西：

EXEC sp_spaceused null, false 

結果：

database_name database_size  unallocated space 
--------------- ------------------ ------------------ 
DATABASE_NAME 220.25 MB   69.92 MB 

reserved   data    index_size   unused
