= Верификација

Проверката е слична за сите табели. 

Подолу е прикажан пример само за `encounters` табелата.

== Проверка дека датотечните групи се креирани исправно

{{{#!sql
select 
    fg.name as FilegroupName,
    df.name as LogicalFileName,
    df.type_desc as FileType,
    df.physical_name as PhysicalPath,
    df.size / 128.0 as SizeMB
from sys.filegroups fg
left join sys.database_files df ON fg.data_space_id = df.data_space_id
order by fg.name;
go
}}}

== Проверка дека партициската шема и функцијата работат исправно

{{{#!sql
select 
    ps.name as PartitionScheme,
    pf.name as PartitionFunction,
    dds.destination_id as PartitionNumber,
    fg.name as FilegroupName,
    prv.value as UpperBoundaryValue
from sys.partition_schemes ps
join sys.partition_functions pf on ps.function_id = pf.function_id
join sys.destination_data_spaces dds on ps.data_space_id = dds.partition_scheme_id
join sys.filegroups fg on dds.data_space_id = fg.data_space_id
left join sys.partition_range_values prv 
    on pf.function_id = prv.function_id 
    and dds.destination_id = case when pf.boundary_value_on_right = 1 then prv.boundary_id + 1 else prv.boundary_id end
where ps.name = 'ps_Encounters_Year'
order by dds.destination_id;
go
-----------------------------
select
    fg.name as FilegroupName,
    df.name as LogicalFileName,
    df.physical_name,
    df.size / 128.0 as SizeMB
from sys.filegroups fg
    left join sys.database_files df on fg.data_space_id = df.data_space_id;
go
}}}

== Дистрибуција по партиции

{{{#!sql
select
    $partition.pf_Encounters_Year([start]) as PartitionNumber,
    count(*) as 'RowCount',
    min([start]) as MinDate,
    max([start]) as MaxDate
from dbo.encounters
group by $partition.pf_Encounters_Year([start])
order by PartitionNumber;
go
}}}

== Filegroup usage

{{{#!sql
select 
    fg.name as FilegroupName,
    count(*) as PartitionCount
from sys.partitions p
join sys.indexes i on p.object_id = i.object_id and p.index_id = i.index_id
join sys.data_spaces ds on i.data_space_id = ds.data_space_id
join sys.filegroups fg on ds.data_space_id = fg.data_space_id
where object_name(p.object_id) = 'Encounters'
group by fg.name;
go
}}}

== Partition elimination

{{{#!sql
set statistics io on
select count(*) from encounters where [start] >= '2022-01-01';
set statistics io off;
}}}
