ここに非常に似た質問があります:
しかし、それは私が望んでいることではありません。
私が入れたものを正確に取り戻したいのです。例えば:
CREATE STATISTICS [_MM_STATS__745366020_7_1_4_5_2_3]
ON [dbo].[ProductShipTax]
([TaxRegionId], [ProductShipTaxID], [TaxRate], [ItemNo], [DateFrom], [DateTo])
たとえば、別のデータベースに適用できるように、上記の正確なスクリプトを取得できるクエリが必要です。
これは可能でしょうか?
文法のこのサブセットをサポートする2005+互換オプションは以下のとおりです。
CREATE STATISTICS statistics_name
ON { table_or_indexed_view_name } ( column [ ,...n ] )
[ WHERE <filter_predicate> ]
[ WITH
[ STATS_STREAM = stats_stream ]
[ [ , ] NORECOMPUTE ]
[ [ , ] INCREMENTAL = { ON | OFF } ]
] ;
注:ただし、2005のサポートは多少制限されます。製品自体は増分またはフィルタリングされた統計をサポートしていません。この機能がCONVERT
に追加される前にバイナリを文字列に変換するにはkludgyの回避策の1つが必要になるため、統計ストリームのサポートを導入していません。

PowerShellに慣れている場合、これは2行のコード(または必要に応じて1行)で実行できます。
#function: on local instance, scripting out [AdventureWorks2012] db auto-created statistics (those stats for indexes are created with the indexes, so no worry needed)
#the generated file is put at c:\temp\stats_auto.sql
import-module sqlps -DisableNameChecking;
foreach ($t in (dir sqlserver:\sql\localhost\default\databases\AdventureWorks2012\Tables))
{
$t.Statistics | ? { $_.IsAutoCreated} | % { "create statistics $($_.name) on [$($t.schema)].[$($t.name)] ( $($_.statisticColumns -join ',') )" } | Out-File c:\temp\stats_auto.sql -append;
}
このスクリプトをPowerShell IDEで実行した後、次のt-sqlコードをc:\ temp\stats_auto.sqlで取得できます。
