SQL Server에서 특정 테이블에 대한 CREATE TABLE 문을 생성하려면 어떻게 해야 합니까?

저는 이 문제에 대한 해결책을 마련하는 데 많은 시간을 할애하고 있기 때문에, 이 투고의 정신에 따라 다른 사람에게 도움이 될 수 있다고 생각하여 여기에 올립니다.

더 좋은 대본이나 추가할 게 있으면 올려주세요.

편집: 네, Management Studio에서 하는 방법은 알고 있습니다만, 다른 어플리케이션에서 할 수 있어야 했습니다.

위의 버전을 수정하여 모든 테이블에서 실행되도록 하고 새로운 SQL 2005 데이터 유형을 지원하도록 했습니다.프라이머리 키명도 유지됩니다.SQL 2005에서만 작동합니다(교차 적용 사용).

업데이트: XML 데이터 유형 처리 추가

업데이트 2: 1) 이름이 같지만 스키마가 다른 여러 테이블이 있는 경우, 2) 이름이 같은 PK 제약 조건이 있는 여러 테이블이 있는 경우 수정됨

제가 생각해낸 대본입니다.ID 열, 기본값 및 기본 키를 처리합니다.외부 키, 인덱스, 트리거 또는 기타 현명한 정보는 처리하지 않습니다.SQL Server 2000, 2005 및 2008에서 작동합니다.

스키마 지원:

이것은 David 등의 훌륭한 답변을 수정한 갱신판입니다.이름 있는 스키마에 대한 지원이 추가되었습니다.다양한 스키마 내에 실제로 같은 이름의 테이블이 존재할 경우 이 테이블이 파손될 수 있습니다.또 다른 개선사항은 공식 QuoteName() 함수를 사용하는 것입니다.

Management Studio에서 사용하는 경우:

위의 SQL 코드를 손상시키는 이유 중 하나는 SSMS를 사용하여 테스트하는 경우 긴 문장을 읽기 쉽지 않다는 것입니다.유용한 게시물에 따르면 그리드의 셀 링크를 클릭하면 보기 쉽도록 수정된 다른 버전이 있습니다.결과는 DB 내의 각 테이블에 대해 올바르게 포맷된 CREATE TABLE 문으로 쉽게 식별할 수 있습니다.

분할된 테이블을 지원하여 답변을 개선합니다.

다음 스크릿을 사용하여 파티션 구성표와 파티션 키를 찾습니다.

declare @partition_scheme varchar(100) = (
select distinct ps.Name AS PartitionScheme
from sys.indexes i  
join sys.partitions p ON i.object_id=p.object_id AND i.index_id=p.index_id  
join sys.partition_schemes ps on ps.data_space_id = i.data_space_id  
where i.object_id = object_id('your table name')
)
print @partition_scheme

declare @partition_column varchar(100) = (
select c.name 
from  sys.tables          t
join  sys.indexes         i 
      on(i.object_id = t.object_id 
  and i.index_id < 2)
join  sys.index_columns  ic 
  on(ic.partition_ordinal > 0 
  and ic.index_id = i.index_id and ic.object_id = t.object_id)
join  sys.columns         c 
  on(c.object_id = ic.object_id 
  and c.column_id = ic.column_id)
where t.object_id  = object_id('your table name')
)
print @partition_column

그런 다음 올바른 위치에 아래 행을 추가하여 생성 쿼리를 변경합니다.

스크립트를 공유한 것에 대해 @Blorgbeard에 대한 크레딧입니다.필요할 때를 대비해서 북마크에 넣어둘게요.

에서 '을 하고 '우클릭'을 로 쓸 수 .CREATE TABLE 스크립트, 스크립트:

  • 스크립트에는 많은 cruft(확장 속성에 관심이 있는 사람)가 포함되어 있습니다.
  • 스키마에 200개 이상의 테이블이 있는 경우 수동으로 로트를 스크립팅하는 데 반나절이 걸립니다.

이 스크립트를 스토어드 프로시저로 변환하고 래퍼 스크립트와 조합하면 테이블 설계를 소스 제어 등에 덤프할 수 있습니다.

나머지 DB 코드(SP, FK 인덱스, 트리거 등)는 소스 제어 하에 있습니다.

INFORMATION_SCHEMA에서 발견한 것.COLUMNS 뷰는 이미지나 텍스트 등의 필드 타입에 대해 2147483647(2^31-1)의 크기를 제공합니다.ntext는 2^30-1(2바이트 Unicode 및 모든 것)입니다.

이 크기는 이 쿼리의 출력에 포함되지만 CREATE 문의 이러한 데이터 유형에 대해서는 유효하지 않습니다(최대 크기 값은 전혀 사용할 수 없습니다).따라서 이 결과를 수동으로 수정하지 않으면 이러한 데이터 유형이 지정된 경우 CREATE 스크립트는 작동하지 않습니다.

이 문제를 해결하기 위해 스크립트를 수정할 수 있다고 생각합니다만, SQL 능력으로는 부족합니다.

드롭 테이블(존재하는 경우)을 작성과 결합하려면 다음과 같이 사용합니다.

SELECT Drop_Table + CHAR(10) + Create_Table FROM SysCreateTables

Management Studio를 사용하고 있고 쿼리 분석기 창이 열려 있는 경우 테이블 이름을 쿼리 분석기 창으로 드래그하여 ... bingo!테이블 스크립트를 얻습니다.SQL2008에서는 이 기능을 사용해 본 적이 없습니다.
