List tables by their size in Azure SQL Database

The query below returns tables in a database with the space they use, sorted by those that use more.


select schema_name(tab.schema_id) + '.' + as [table],
    cast(sum(spc.used_pages * 8)/1024.00 as numeric(36, 2)) as used_mb,
    cast(sum(spc.total_pages * 8)/1024.00 as numeric(36, 2)) as allocated_mb
from sys.tables tab
    inner join sys.indexes ind 
        on tab.object_id = ind.object_id
    inner join sys.partitions part 
        on ind.object_id = part.object_id and ind.index_id = part.index_id
    inner join sys.allocation_units spc
        on part.partition_id = spc.container_id
group by schema_name(tab.schema_id) + '.' +
order by sum(spc.used_pages) desc


  • table - table name with schema name
  • used_mb - space used in MB
  • allocated_mb - space allocated in MB


  • One row: represents one table in a database
  • Scope of rows: all tables in a database
  • Ordered by: table used size, from largest to smallest
