Question

Can we have a SQL query which will basically help in viewing table and index sizes in SQl Server.

How SQL server maintains memory usage for tables/indexes?

Answer 1

The exec sp_spaceused without parameter shows the summary for the whole database. The foreachtable solution generates one result set per table – which SSMS might not be able to handle if you have too many tables.

I created a script which collects the table infos via sp_spaceused and displays a summary in a single record set, sorted by size.

create table #t (   name nvarchar(128),   rows varchar(50),   reserved varchar(50),   data varchar(50),   index_size varchar(50),   unused varchar(50) )  declare @id nvarchar(128) declare c cursor for select '[' + sc.name + '].[' + s.name + ']' FROM sysobjects s INNER JOIN sys.schemas sc ON s.uid = sc.schema_id where s.xtype='U'  open c fetch c into @id  while @@fetch_status = 0 begin    insert into #t   exec sp_spaceused @id    fetch c into @id end  close c deallocate c  select * from #t order by convert(int, substring(data, 1, len(data)-3)) desc  drop table #t
