테이블의 전체 구조 복사
답변:
물론 UI를 사용하여 테이블을 비교적 쉽게 스크립팅 할 수 있습니다.
그러면 CREATE TABLE스크립트 가 출력 되며 이전 이름을 검색하여 새 이름으로 바꾸면됩니다 (그리고 새 이름을 가진 개체가 아직 존재하지 않는지 확인).
그러나 이것을 자동화하려고하면 (예 : 코드에서 테이블 작성 스크립트 생성) 좀 더 성가시다. 위의 스크립팅 옵션은 CREATE TABLE메타 데이터의 단일 위치에서 전체 DDL을 가져 오는 것이 아닙니다 . 코드에서 장면 뒤에서 마술을 많이 사용하여 최종 CREATE TABLE스크립트 를 생성합니다 (프로파일 러를 사용하여 데이터를 가져 오는 위치를 볼 수는 있지만 어떻게 어셈블하는지 알 수는 없습니다). 나는 이것에 대한 옵션을 제안했다.

그러나 이것은 매우 적은 표를 얻었고 Microsoft에 의해 신속하게 격추되었습니다. 스키마 생성을 위해 타사 도구를 사용하는 것이 훨씬 더 가치가 있음을 알 수 있습니다 ( 블로그에 대해 블로그했습니다 ).
SQL Server 2012에는 2005, 2008 및 2008 R2에서 수행해야하는 작업보다 훨씬 가까이 접근 할 수있는 메타 데이터 기능이 새로 추가되어 메타 데이터의 열 정보 (예 : [n [var [char]]에 길이 사양을 추가해야하는 경우 정밀도 / 스케일을 추가해야합니다. n [var] char에 대해 max_length를 반으로 잘라야하는 경우 MAX 인 경우 -1을 MAX 등으로 변경하십시오). SQL Server 2012에서는이 부분이 조금 더 쉽습니다.
SELECT name, system_type_name, is_nullable FROM
sys.dm_exec_describe_first_result_set('select * from sys.objects', NULL, 0)
결과 :
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
아마도 이것은을 CREATE TABLE사용하는 복잡한 접근법보다 목표 진술에 훨씬 가깝지만 sys.columns여전히 할 일이 많이 있습니다. 키, 제약 조건, 텍스트 행 옵션, 파일 그룹 정보, 압축 설정, 색인 등 매우 긴 목록이므로 다시 반복 할 위험이 있으므로 타사 도구를 다시 살펴볼 것을 제안합니다. 바퀴를 재발 명하는 비유를 사용했습니다.
코드를 통해이 작업을 수행해야하지만 SQL Server 외부에서 수행 할 수 있다면 SMO / PowerShell을 고려할 수 있습니다. 이 팁 과 Scripter.Script () 메서드를 참조하십시오 .
sys.dm_exec_describe_first_result_set은 OLEDB에서 실행될 경우 datetime2 대신 nvarchar (27)을 표시합니다.

이것은 적대적이거나 부정적인 것이 아닙니다. 그러나 이런 종류의 일은 SQL로 20 년 후 Postgres로 이사 한 이유입니다. Postgres 솔루션은 다음과 같습니다. CREATE TABLE tbl2 (LIKE tbl1 INCLUDING ALL); -모든 색인 주석 등을 포함한 표를 복제합니다.

@DamienSawyer 공정하게, 동일한 인덱스와 다른 모든 것을 가진 동일한 테이블을 여러 개 만드는 것은 일종의 디자인 냄새입니다. 그리고 실제로 필요할 때 도움을 줄 수있는 많은 타사 도구 (일부 무료, 일부 오픈 소스)가 있습니다.

물론 @AaronBertrand는 특히 유비쿼터스 3NF CRUD 스타일 스키마에서 매우 사실입니다. 때때로 우리는 데이터베이스를 덜 단단하게 사용합니다. 예를 들어, CSV와 같은 비공식 소스에서 데이터를 정리하여 프로덕션 시스템으로 마이그레이션하는 등의 데이터를 정리합니다. 비교를 위해 Excel이 훌륭한 이유 중 하나는 통합 문서가 복잡해질 수 있지만 매우 간단한식이 없기 때문입니다. 한 장의 종이는 집을 사기위한 계약과 쇼핑리스트를 작성하는 계약으로 사용될 수 있습니다.

Damien Sawyer
@DamienSawyer 그리고 기본적으로 폐기 단계 준비 테이블 인 중간 프로세스가있을 때 테이블에 존재하는 인덱스, 제약 조건, 확장 속성 등을 모두 포함 할 필요는 없다고 주장합니다. 그것을 모델화하고 있습니다. 다른 사용 사례가 존재하더라도 기본 동작에는 매우 유효한 사용 사례가 있습니다.

이 sp를 작성하여 모든 것, pk, fk, 파티션, 제약 조건이있는 스키마를 자동으로 생성했습니다 ...

스크립트를 수정했습니다 : 고정 TEXT 열 지원 및 테이블 생성 및 데이터 복사 기능이 추가되었습니다. 데이터는 복사했지만 스키마는 아닌 'SELECT * INTO NewTable FROM OldTable'대신 사용할 수 있습니다. gist.github.com/MNF/eb905c7ec215670a3abc62f9c2cf9d7b

이것은 착암기를 사용하여 벽에 못을 넣을 수도 있지만 질문의 폭이 넓기 때문에 언급 할 수있는 유효한 옵션이라고 생각합니다.
SQL Server 2012 SP4 +, 2014 SP2 + 또는 2016 SP1 + DBCC CLONEDATABASE를 사용하는 경우 데이터베이스 전용 데이터의 스키마 전용 복사본을 만드는 데 활용할 수 있습니다. 이는 여러 테이블의 포괄적 인 스키마 복사본을 생성하는 데 이상적이며 일련의 테이블을 반복하는 프로세스를 "자동화"할 필요성을 완화 할 수 있지만 모든 테이블 복사본이 새로운 읽기 전용 데이터베이스 내에 생성 될 것임을 경고합니다. .
이 표는 것이다 외래 키, 기본 키, 인덱스 및 제약 조건을 포함한다. 또한 통계 및 쿼리 데이터를 저장 (사용자가 지정하지 않는 한 포함 NO_STATISTICS하고 NO_QUERYSTORE).
문법은
DBCC CLONEDATABASE (source_database_name, target_database_name)[WITH [NO_STATISTICS][,NO_QUERYSTORE]] 이 브렌트 Ozar가 가지고있는,주의해야 할 몇 가지 다른주의 사항이 또한 큰 포스트 에,하지만 그것은 모두 정말 아래로 비등하는 방법과 당신에 관한 테이블의 복사본을 만들 이유 여부 미묘의는 거래 차단기는 .
SQL Server Management Studio에서 "스크립트 생성"명령을 사용하여 인덱스, 트리거, 외래 키 등 테이블을 생성 할 수있는 스크립트를 얻을 수 있습니다.
SSMS에서
- 테이블이있는 데이터베이스를 마우스 오른쪽 단추로 클릭하십시오.
- 작업-> 스크립트 생성을 선택하십시오.
- "특정 데이터베이스 오브젝트 선택"을 선택하십시오.
- "테이블"목록을 펼치고 스크립트하려는 테이블 옆에있는 확인란을 선택하십시오.
- "다음"을 클릭하여 마법사의 다음 페이지로 이동하십시오.
- 저장 옵션을 원하는대로 설정 한 다음 "고급"버튼을 클릭하십시오
- 원하는대로 고급 옵션을 설정하십시오. 특히, "테이블 /보기 옵션"에서 기본적으로 인덱스, 트리거 및 전체 텍스트 인덱스는 스크립팅 되지 않습니다 . 원하는 경우 "False"에서 "True"로 전환하십시오.
- 완료되면 "확인"을 클릭하여 고급 옵션을 저장하고 "다음"을 클릭하여 선택 사항을 검토하십시오. 스크립트를 실제로 생성하려면 "다음"을 다시 클릭하십시오.
그런 다음 대상 데이터베이스에 필요한 내용 만 포함하도록 편집 할 수 있습니다.
이 스레드에서 E.Mantovanelli의 버전을 기반으로 한 버전이 있습니다. 이는 고유 인덱스가 결과 스크립트에 키워드 UNIQUE를 포함하지 않는 문제를 수정합니다. 또한 비 클러스터형 인덱스없이 테이블을 만들거나 비 클러스터형 인덱스 만 스크립팅 할 수 있도록 매개 변수를 추가합니다. 이것을 사용하여 스테이지 테이블을 작성하고 비 클러스터형 인덱스를 추가 한 다음 테이블 스위치를 수행하여로드가 더 빠르게 실행되고 인덱스가 조각화되지 않도록합니다.

-- 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.
