Skopiuj pełną strukturę tabeli

Używając niektórych metod, podczas tworzenia kopii tabeli tracisz indeksy, PK, FK itp. Na przykład w SQL Server mogę powiedzieć:

select * into dbo.table2 from dbo.table1;

To tylko prosta kopia tabeli; brakuje wszystkich indeksów / ograniczeń. Jak mogę skopiować strukturę tabeli (bez użycia kopii zapasowej)?

Przede wszystkim chcę to zrobić ręcznie, ale jeśli nie będzie to możliwe, zaakceptuję każde rozwiązanie.

Oczywiście możesz napisać tabelę stosunkowo łatwo za pomocą interfejsu użytkownika:

Spowoduje to wygenerowanie a CREATE TABLE skryptu i wystarczy wyszukać i zastąpić starą nazwę nową nazwą (i sprawdzić, czy obiekt o nowej nazwie jeszcze nie istnieje).

Ale jeśli próbujesz to zautomatyzować (np. Wygenerować skrypt tworzenia tabeli w kodzie), jest to trochę bardziej kłopotliwe. Powyższa opcja skryptu nie tylko wyciąga cały CREATE TABLEDDL z jednego miejsca w metadanych; robi całą masę magii za kulisami w kodzie, aby wygenerować ostateczny CREATE TABLEskrypt (możesz użyć Profiler, aby zobaczyć, skąd bierze swoje dane, ale nie możesz zobaczyć, jak to składa). Zasugerowałem opcję:

http://connect.microsoft.com/SQLServer/feedback/details/273934

Jednak spotkało się to z bardzo małą liczbą głosów i zostało szybko zestrzelone przez Microsoft. O wiele bardziej opłacalne może być użycie zewnętrznego narzędzia do generowania schematu ( pisałem o tym na blogu ).

W SQL Server 2012 wprowadzono nowe funkcje metadanych, które pozwalają zbliżyć się znacznie do pracy, którą należy wykonać w 2005, 2008 i 2008 R2, gromadząc informacje o kolumnach z metadanych (które zawierają wiele zastrzeżeń, na przykład jeśli jest to dziesiętny musisz dodać precyzję / skalę, jeśli [n [var [char]] musisz dodać specyfikację długości, jeśli n [var] char musisz przeciąć max_length na pół, jeśli jest to MAX, musisz zmień -1 na MAX itp.). W SQL Server 2012 ta część jest trochę łatwiejsza:

SELECT name, system_type_name, is_nullable FROM
  sys.dm_exec_describe_first_result_set('select * from sys.objects', NULL, 0)

Wyniki:

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

Pisałem też o tym na blogu.

Prawdopodobnie jest to znacznie bliższe twojemu ukierunkowanemu CREATE TABLEstwierdzeniu niż skomplikowane podejściesys.columns , ale wciąż pozostaje wiele do zrobienia. Klucze, ograniczenia, opcje tekstu w wierszach, informacje o grupie plików, ustawienia kompresji, indeksy itp. To bardzo długa lista i jeszcze raz zasugeruję, abyś spojrzał na to narzędzie zewnętrzne, zamiast ryzykować powtórzenie - wykorzystał analogię, ponownie wymyślając koło.

To powiedziawszy, jeśli musisz to zrobić za pomocą kodu, ale możesz to zrobić poza SQL Server, możesz rozważyć SMO / PowerShell. Zobacz tę wskazówkę i metodę Scripter.Script () .

napisałem ten sp, aby automatycznie utworzyć schemat ze wszystkimi rzeczami, pk, fk, partycjami, ograniczeniami ...

Może to być użycie młota pneumatycznego do wbicia gwoździa w ścianę, ale biorąc pod uwagę szeroki zakres pytania, myślę, że warto o tym wspomnieć.

Jeśli korzystasz z SQL Server 2012 SP4 +, 2014 SP2 + lub 2016 SP1 +, możesz użyć dźwigni, DBCC CLONEDATABASEaby utworzyć kopię bazy danych bez danych tylko do schematu. Jest to idealne rozwiązanie do generowania kompleksowych kopii schematu wielu tabel i może zmniejszyć potrzebę „automatyzacji” procesu zapętlania szeregu tabel, ale należy pamiętać, że wszystkie kopie tabel zostaną utworzone w nowej bazie danych tylko do odczytu .

Te tabele będą zawierać klucze obce, klucze podstawowe, indeksy i ograniczenia. Będą również zawierać statystyki i dane z magazynu zapytań (chyba że określisz NO_STATISTICSi NO_QUERYSTORE).

Składnia jest następująca

DBCC CLONEDATABASE (source_database_name, target_database_name)[WITH [NO_STATISTICS][,NO_QUERYSTORE]] 

Jest też kilka innych zastrzeżeń, o których Brent Ozar ma świetny post , ale wszystko naprawdę sprowadza się do tego, jak i dlaczego chcesz tworzyć kopie tabel, czy któraś z subtelności jest łamaczem, czy nie .

Możesz użyć polecenia „Generuj skrypt” w SQL Server Management Studio, aby uzyskać skrypt, który może utworzyć Twoją tabelę, w tym indeksy, wyzwalacze, klucze obce itp.

W SSMS

• Kliknij prawym przyciskiem myszy bazę danych, w której znajduje się tabela
• Wybierz Zadania -> Generuj skrypty
• Wybierz „Wybierz określone obiekty bazy danych”
• Rozwiń listę „Tabele” i zaznacz pole wyboru obok tabeli, którą chcesz skryptować
• Kliknij „Dalej”, aby przejść do następnej strony kreatora
• Ustaw opcje zapisywania tak, jak chcesz, a następnie kliknij przycisk „Zaawansowane”
• Ustaw zaawansowane opcje tak, jak chcesz. W szczególności w „Opcjach tabeli / widoku” zwróć uwagę, że (domyślnie) indeksy, wyzwalacze i indeksy pełnotekstowe nie są skryptowane; jeśli chcesz, zmień je z „False” na „True”
• Po zakończeniu kliknij „OK”, aby zapisać zaawansowane opcje, i „Dalej”, aby przejrzeć wybrane opcje. Kliknij ponownie „Dalej”, aby faktycznie wygenerować skrypt.

Następnie możesz edytować, aby uwzględnić tylko to, czego potrzebujesz w docelowej bazie danych.

Oto wersja oparta na wersji E.Mantovanelli w tym wątku. Rozwiązuje to problem polegający na tym, że unikalny indeks nie zawiera słowa kluczowego UNIQUE w skrypcie wynikowym. Dodaje również parametry, dzięki czemu można utworzyć tabelę bez indeksów nieklastrowanych lub można jedynie skryptować indeksy nieklastrowane. Używam tego do utworzenia tabeli stołu montażowego, załadowania, dodania indeksów nieklastrowanych, a następnie przełączenia tabeli, które pozwalają na szybsze ładowanie, a indeksy nie są pofragmentowane.

--    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.
