Zkopírujte kompletní strukturu tabulky
Při použití některých metod ztratíte při vytváření kopie tabulky indexy, PK, FK atd. Například v SQL Serveru mohu říci:
select * into dbo.table2 from dbo.table1;
Toto je pouze jednoduchá kopie tabulky; chybí všechny indexy/omezení. Jak mohu zkopírovat strukturu tabulky (bez použití zálohy)?
V první řadě to hledám ručně, ale pokud to není možné, přijmím jakékoli řešení.
Tabulku můžete skrýt poměrně snadno pomocí uživatelského rozhraní:
Výsledkem bude CREATE TABLE script a musíte pouze vyhledat a nahradit staré jméno novým jménem (a ověřit, že objekt s novým názvem již neexistuje).
Ale pokud se to snažíte automatizovat (např. Vygenerovat skript vytvoření tabulky v kódu), je to trochu těžkopádnější. Výše uvedená možnost skriptování netáhne pouze celé CREATE TABLE DDL z jednoho místa v metadatech; to dělá spoustu magie za scénami v kódu generovat eventuální CREATE TABLE skript (můžete použít Profiler, abyste zjistili, kde získává svá data, ale nemůžete vidět, jak je sestavuje). Navrhl jsem pro to jednu z možností:
http://connect.Microsoft.com/SQLServer/feedback/details/273934
To se však setkalo s několika málo hlasy a společnost Microsoft je rychle sestřelila. Možná bude pro vás mnohem užitečnější použít pro vygenerování schématu nástroj třetí strany ( o tom jsem blogoval ).
V SQL Server 2012 existují nové funkce metadat, které vám umožní se dostat mnohem blíže než práce, kterou musíte udělat v letech 2005, 2008 a 2008 R2, a shromažďovat informace o sloupcích z metadat (která má mnoho upozornění, například pokud je to desetinné číslo musíte přidat přesnost/měřítko, pokud [n [var [char]] musíte přidat specifikaci délky, pokud n [var] char musíte snížit max_length na polovinu, pokud je MAX, musíte změnit -1 na MAX atd.). V SQL Server 2012 je tato část o něco jednodušší:
SELECT name, system_type_name, is_nullable FROM
sys.dm_exec_describe_first_result_set('select * from sys.objects', NULL, 0)
Výsledek:
name system_type_name is_nullable
-------------------- ---------------- -----------
name nvarchar(128) 0
object_id int 0
principal_id int 1
schema_id int 0
parent_object_id int 0
type char(2) 0
type_desc nvarchar(60) 1
create_date datetime 0
modify_date datetime 0
is_ms_shipped bit 0
is_published bit 0
is_schema_published bit 0
Pravděpodobně je to mnohem blíže vaší cílové CREATE TABLE prohlášení než spletitý přístup pomocí sys.columns, ale je ještě mnoho práce. Klíče, omezení, text v řádcích, informace o souborových skupinách, nastavení komprese, indexy atd. Je to velmi dlouhý seznam a já vám znovu navrhnu, abyste se místo toho podívali na nástroj třetí strany, s rizikem opakování opakování -používal analogii, znovu vynalezl kolo.
To vše říká, pokud to potřebujete udělat prostřednictvím kódu, ale můžete to udělat mimo SQL Server, můžete zvážit SMO/PowerShell. Viz tento tip a metoda Scripter.Script () .
napsal jsem tento sp, abych automaticky vytvořil schéma se všemi věcmi, pk, fk, oddíly, omezení ...

To by mohlo být pomocí sbíječky k vložení hřebíku do zdi, ale vzhledem k šíři otázky si myslím, že je platnou možností zmínit se.
Pokud používáte SQL Server 2012 SP4 +, 2014 SP2 + nebo 2016 SP1 +, můžete využít DBCC CLONEDATABASE vytvoříte kopii dat bez databáze ve schématu. To je ideální pro generování komplexních kopií schématu více tabulek a může to zmírnit potřebu „automatizovat“ proces opakování v sérii tabulek, ale je třeba upozornit, že všechny kopie tabulek budou vytvořeny uvnitř nové databáze pouze pro čtení .
Tyto tabulky budou zahrnovat cizí klíče, primární klíče, indexy a omezení. Zahrnují také statistiky a data úložiště dotazů (pokud nezadáte NO_STATISTICS a NO_QUERYSTORE).
Syntaxe je
DBCC CLONEDATABASE (source_database_name, target_database_name)[WITH [NO_STATISTICS][,NO_QUERYSTORE]]
Je zde také několik dalších upozornění, o kterých má Brent Ozar skvělý příspěvek , ale vše se opravdu scvrkává na to, jak a proč chcete vytvářet kopie tabulek o tom, zda nebo ne některá z jemností jsou jističe obchodů.
Pomocí příkazu „Vygenerovat skript“ v SQL Server Management Studio získáte skript, který může vytvořit vaši tabulku, včetně indexů, triggerů, cizích klíčů atd.
V SSMS
- Klepněte pravým tlačítkem myši na databázi, ve které je tabulka
- Zvolte Úkoly -> Generovat skripty
- Zvolte „Vybrat konkrétní databázové objekty“
- Rozbalte seznam "Tabulky" a zaškrtněte políčko vedle tabulky, kterou chcete skriptovat
- Kliknutím na „Další“ přejdete na další stránku průvodce
- Nastavte možnosti uložení tak, jak chcete, a poté klikněte na tlačítko „Upřesnit“
- Nastavte pokročilé možnosti tak, jak chcete. Zejména v části „Možnosti tabulky/zobrazení“ si všimněte, že (ve výchozím nastavení) jsou indexy, spouštěče a fulltextové indexy ne skriptovány; pokud je chcete, přepněte je z „False“ na „True“
- Až budete hotovi, klikněte na „OK“ pro uložení vašich pokročilých možností a „Další“ pro kontrolu vašeho výběru. Skript znovu vygenerujete kliknutím na tlačítko „Další“.
Poté můžete upravit a zahrnout přesně to, co potřebujete do cílové databáze.
Zde je verze založená na verzi E.Mantovanelliho v tomto vlákně. To opravuje problém, kdy jedinečný index nezahrnul do výsledného skriptu klíčové slovo UNIQUE. Přidá také parametry, takže tabulka může být vytvořena bez indexů bez klastru nebo můžete skriptovat pouze indexy bez klastru. Používám to k vytvoření stolní tabulky, načtení, přidání neindustrovaných indexů a poté přepnutí tabulky, které umožní zatížení běžet rychleji a indexy nejsou fragmentovány.

-- Creates a copy of a table with optionally all indexes and constraints depending on parameters
-- Updated by : Brent Willis
-- Date Updated : 09-11-2019
-- Changes: Added the ability to create a table with clustered index and constraints only or to
-- CREATE just the non-clustered indexes. This is helpful so a table can be created,
-- loaded then non-clusted indexes added so it can them be swapped into a partitioned
-- table with freshly created indexes to lower fragmentation.
--
-- Also fixed an issue when a unique index was defined the index resulting table was not unique.
