Ottenere Tavolo e stoccaggio Indice dimensioni in SQL Server

Question

voglio ottenere i dati della tabella e lo spazio di indice per ogni tabella nel mio database:

Table Name    Data Space   Index Space 
------------------------------------------------------- 

Come posso ottenere questo risultato?

Answer 1

Questa query qui elencherà la dimensione totale che una tabella riprende - indice cluster, heap e tutti gli indici non cluster:

SELECT 
    s.Name AS SchemaName, 
    t.NAME AS TableName, 
    p.rows AS RowCounts, 
    SUM(a.total_pages) * 8 AS TotalSpaceKB, 
    SUM(a.used_pages) * 8 AS UsedSpaceKB, 
    (SUM(a.total_pages) - SUM(a.used_pages)) * 8 AS UnusedSpaceKB 
FROM 
    sys.tables t 
INNER JOIN 
    sys.schemas s ON s.schema_id = t.schema_id 
INNER JOIN  
    sys.indexes i ON t.OBJECT_ID = i.object_id 
INNER JOIN 
    sys.partitions p ON i.object_id = p.OBJECT_ID AND i.index_id = p.index_id 
INNER JOIN 
    sys.allocation_units a ON p.partition_id = a.container_id 
WHERE 
    t.NAME NOT LIKE 'dt%' -- filter out system tables for diagramming 
    AND t.is_ms_shipped = 0 
    AND i.OBJECT_ID > 255 
GROUP BY 
    t.Name, s.Name, p.Rows 
ORDER BY 
    s.Name, t.Name 

Se si vuole separare spazio tabella dallo spazio indice, è necessario utilizzare AND i.index_id IN (0,1) per lo spazio tabella (index_id = 0 è lo spazio mucchio, index_id = 1 è la dimensione dell'indice cluster = pagine di dati) e AND i.index_id > 1 per lo spazio indice solo

with pages as (
    SELECT object_id, SUM (reserved_page_count) as reserved_pages, SUM (used_page_count) as used_pages, 
      SUM (case 
        when (index_id < 2) then (in_row_data_page_count + lob_used_page_count + row_overflow_used_page_count) 
        else lob_used_page_count + row_overflow_used_page_count 
       end) as pages 
    FROM sys.dm_db_partition_stats 
    group by object_id 
), extra as (
    SELECT p.object_id, sum(reserved_page_count) as reserved_pages, sum(used_page_count) as used_pages 
    FROM sys.dm_db_partition_stats p, sys.internal_tables it 
    WHERE it.internal_type IN (202,204,211,212,213,214,215,216) AND p.object_id = it.object_id 
    group by p.object_id 
) 
SELECT object_schema_name(p.object_id) + '.' + object_name(p.object_id) as TableName, (p.reserved_pages + isnull(e.reserved_pages, 0)) * 8 as reserved_kb, 
     pages * 8 as data_kb, 
     (CASE WHEN p.used_pages + isnull(e.used_pages, 0) > pages THEN (p.used_pages + isnull(e.used_pages, 0) - pages) ELSE 0 END) * 8 as index_kb, 
     (CASE WHEN p.reserved_pages + isnull(e.reserved_pages, 0) > p.used_pages + isnull(e.used_pages, 0) THEN (p.reserved_pages + isnull(e.reserved_pages, 0) - p.used_pages + isnull(e.used_pages, 0)) else 0 end) * 8 as unused_kb 
from pages p 
left outer join extra e on p.object_id = e.object_id 

prende in considerazione tabelle interne, come tho se usato per l'archiviazione XML.

Edit: Se si divide i valori data_kb e index_kb da 1.024,0, si ottengono i numeri che vedi nella GUI.
