Kopieren Sie die vollständige Struktur einer Tabelle
Mit einigen Methoden verlieren Sie beim Erstellen einer Kopie einer Tabelle Indizes, PK, FK usw. Zum Beispiel kann ich in SQL Server sagen:
select * into dbo.table2 from dbo.table1;
Dies ist nur eine einfache Kopie der Tabelle. Alle Indizes/Einschränkungen fehlen. Wie kann ich eine Tabellenstruktur kopieren (ohne ein Backup zu verwenden)?
Ich möchte dies hauptsächlich manuell tun, aber wenn dies nicht möglich ist, akzeptiere ich jede Lösung.
Sie können eine Tabelle natürlich relativ einfach über die Benutzeroberfläche skripten:
Dies gibt ein CREATE TABLE Skript und Sie müssen nur den alten Namen suchen und durch den neuen Namen ersetzen (und sicherstellen, dass ein Objekt mit dem neuen Namen noch nicht vorhanden ist).
Wenn Sie jedoch versuchen, dies zu automatisieren (z. B. das Skript zum Erstellen einer Tabelle im Code zu generieren), ist dies etwas umständlicher. Die obige Skriptoption zieht nicht nur das gesamte CREATE TABLE DDL von einem einzelnen Ort in den Metadaten; Es macht eine ganze Menge Magie hinter den Kulissen des Codes, um das eventuelle CREATE TABLE script (Sie können Profiler verwenden, um zu sehen, woher es seine Daten bezieht, aber Sie können nicht sehen, wie es sie zusammensetzt). Ich schlug eine Option dafür vor:
http://connect.Microsoft.com/SQLServer/feedback/details/273934
Dies wurde jedoch mit sehr wenigen Stimmen getroffen und von Microsoft schnell abgeschossen. Möglicherweise lohnt es sich viel mehr, ein Tool eines Drittanbieters zum Generieren eines Schemas zu verwenden ( Ich habe darüber gebloggt ).
In SQL Server 2012 gibt es neue Metadatenfunktionen, mit denen Sie viel näher an die Arbeit herangehen können, die Sie in den Jahren 2005, 2008 und 2008 R2 ausführen müssen, indem Sie Spalteninformationen aus den Metadaten zusammensetzen (was beispielsweise viele Einschränkungen mit sich bringt Dezimal müssen Sie die Genauigkeit/Skalierung hinzufügen, wenn [n [var [char]] Sie die Längenangabe hinzufügen müssen, wenn n [var] char Sie die max_length halbieren müssen, wenn es ein MAX ist, müssen Sie ändere -1 in MAX, etc etc). In SQL Server 2012 ist dieser Teil etwas einfacher:
SELECT name, system_type_name, is_nullable FROM
sys.dm_exec_describe_first_result_set('select * from sys.objects', NULL, 0)
Ergebnisse:
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
Ich habe auch darüber gebloggt.
Wahrscheinlich ist dies viel näher an Ihrem Ziel CREATE TABLE Aussage als ein verschlungener Ansatz mit sys.columns, aber es gibt noch viel zu tun. Schlüssel, Einschränkungen, Text in Zeilenoptionen, Dateigruppeninformationen, Komprimierungseinstellungen, Indizes usw. Es ist eine sehr lange Liste, und ich schlage noch einmal vor, dass Sie sich dafür ein Tool eines Drittanbieters ansehen, anstatt das Risiko einzugehen, dass ein Over wiederholt wird -gebrauchte Analogie, das Rad neu zu erfinden.
Wenn Sie dies jedoch über Code tun müssen, dies jedoch außerhalb von SQL Server tun können, können Sie SMO/PowerShell in Betracht ziehen. Siehe dieser Tipp und die Scripter.Script () -Methode .
ich habe dieses SP geschrieben, um automatisch das Schema mit allen Dingen zu erstellen, pk, fk, Partitionen, Einschränkungen ...

Dies könnte sein, dass ein Presslufthammer verwendet wird, um einen Nagel in eine Wand zu stecken, aber angesichts der Breite der Frage halte ich es für eine gültige Option, dies zu erwähnen.
Wenn Sie SQL Server 2012 SP4 +, 2014 SP2 + oder 2016 SP1 + verwenden, können Sie DBCC CLONEDATABASE verwenden, um eine Nur-Schema-Kopie Ihrer Datenbank ohne Daten zu erstellen. Dies ist ideal zum Generieren umfassender Schemakopien mehrerer Tabellen und kann die Notwendigkeit verringern, den Prozess des Durchlaufens einer Reihe von Tabellen zu "automatisieren". Beachten Sie jedoch, dass alle Tabellenkopien in einer neuen schreibgeschützten Datenbank erstellt werden .
Diese Tabellen enthalten Fremdschlüssel, Primärschlüssel, Indizes und Einschränkungen. Sie enthalten auch Statistiken und Abfragespeicherdaten (es sei denn, Sie geben NO_STATISTICS Und NO_QUERYSTORE An).
Die Syntax lautet
DBCC CLONEDATABASE (source_database_name, target_database_name)[WITH [NO_STATISTICS][,NO_QUERYSTORE]]
Es gibt noch ein paar andere Vorbehalte zu beachten, bei denen Brent Ozar einen großartiger Beitrag hat, aber alles läuft wirklich darauf hinaus, wie und warum Sie Kopien von Tabellen erstellen möchten, ob oder nicht Alle Feinheiten sind Deal Breaker.
Mit dem Befehl "Skript generieren" in SQL Server Management Studio können Sie ein Skript abrufen, mit dem Sie Ihre Tabelle erstellen können, einschließlich Indizes, Triggern, Fremdschlüsseln usw.
In SSMS
- Klicken Sie mit der rechten Maustaste auf die Datenbank, in der sich die Tabelle befindet
- Wählen Sie Aufgaben -> Skripte generieren
- Wählen Sie "Bestimmte Datenbankobjekte auswählen".
- Erweitern Sie die Liste "Tabellen" und aktivieren Sie das Kontrollkästchen neben der Tabelle, die Sie skripten möchten
- Klicken Sie auf "Weiter", um zur nächsten Seite des Assistenten zu gelangen
- Stellen Sie die Speicheroptionen wie gewünscht ein und klicken Sie dann auf die Schaltfläche "Erweitert"
- Stellen Sie die erweiterten Optionen nach Ihren Wünschen ein. Beachten Sie insbesondere unter "Tabellen-/Ansichtsoptionen", dass (standardmäßig) Indizes, Trigger und Volltextindizes nicht skriptgesteuert sind. Wenn Sie diese möchten, wechseln Sie sie von "False" zu "True".
- Wenn Sie fertig sind, klicken Sie auf "OK", um Ihre erweiterten Optionen zu speichern, und auf "Weiter", um Ihre Auswahl zu überprüfen. Klicken Sie erneut auf "Weiter", um das Skript tatsächlich zu generieren.
Sie können dann bearbeiten, um genau das, was Sie benötigen, in Ihre Zieldatenbank aufzunehmen.
Hier ist eine Version, die auf der von E.Mantovanelli in diesem Thread basiert. Dies behebt ein Problem, bei dem ein eindeutiger Index das Schlüsselwort UNIQUE nicht im resultierenden Skript enthielt. Außerdem werden Parameter hinzugefügt, sodass eine Tabelle ohne nicht gruppierte Indizes erstellt werden kann oder Sie nur die nicht gruppierten Indizes skripten können. Ich verwende dies, um eine Stufentabelle zu erstellen, sie zu laden, die nicht gruppierten Indizes hinzuzufügen und dann einen Tabellenwechsel durchzuführen, damit die Last schneller ausgeführt werden kann und die Indizes nicht fragmentiert sind.

-- 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.
