[sql] 하나의 SQL 문에서 모든 테이블, 저장 프로 시저, 트리거, 제약 조건 및 모든 종속성을 삭제하십시오.

모든 테이블을 삭제하고 하나의 SQL 문에서 저장 프로 시저, 트리거, 제약 조건 및 모든 종속성을 삭제하여 SQl Server 2005에서 데이터베이스를 정리할 수있는 방법이 있습니까?

요청 이유 :

새 DB를 생성하는 대신 사용하지 않는 기존 DB를 정리하기위한 DB 스크립트를 갖고 싶습니다. 특히 DB 관리자에게 요청을하고 잠시 기다려야 할 때 특히 그렇습니다!



답변

이 스크립트는 모든 뷰, SPS, 함수 PK, FK 및 테이블을 정리합니다.

Adam Anderson이이 스크립트를 사용하고 있으며 dbo가 아닌 다른 스키마의 객체를 지원하도록 업데이트되었습니다.

declare @n char(1)
set @n = char(10)

declare @stmt nvarchar(max)

-- procedures
select @stmt = isnull( @stmt + @n, '' ) +
    'drop procedure [' + schema_name(schema_id) + '].[' + name + ']'
from sys.procedures


-- check constraints
select @stmt = isnull( @stmt + @n, '' ) +
'alter table [' + schema_name(schema_id) + '].[' + object_name( parent_object_id ) + ']    drop constraint [' + name + ']'
from sys.check_constraints

-- functions
select @stmt = isnull( @stmt + @n, '' ) +
    'drop function [' + schema_name(schema_id) + '].[' + name + ']'
from sys.objects
where type in ( 'FN', 'IF', 'TF' )

-- views

    'alter table [' + schema_name(schema_id) + '].[' + object_name( parent_object_id ) + '] drop constraint [' + name + ']'
from sys.foreign_keys

가장 좋은 방법은 ” 드롭을위한 스크립트 생성 “입니다.

데이터베이스 -> 오른쪽 클릭 -> 작업 -> 스크립트 생성을 선택 하십시오스크립트 생성을 위한 마법사 가 열립니다.

스크립팅 옵션 설정에서 객체를 선택한 후 고급 버튼을 클릭하십시오.

  • -> ‘Script to create’옵션을 true로 설정하십시오 (만들기를 원합니다)

  • -> 옵션 ‘ Script to Drop ‘을 true 설정하십시오 ( 삭제 하고 싶습니다)

  • -> 체크 박스를 선택하여 스크립트를 생성하려는 객체를 선택하십시오.

  • -> 스크립트를 작성할 선택 사항을 선택하십시오 (파일, 새 창, 클립 보드)

  • 기본적으로 종속 객체가 포함됩니다 (처음에는 제약 조건이 삭제됨).

    스크립트를 실행

이런 식으로 스크립트를 사용자 정의 할 수 있습니다.


답변

모든 테이블을 삭제하려면

exec sp_MSforeachtable 'DROP TABLE ?'

물론 이것은 저장 프로 시저를 제외한 모든 제약 조건, 트리거 등을 삭제합니다.

저장 프로 시저의 경우에 저장 된 다른 저장 프로 시저가 필요합니다 master.


답변

나는 두 가지 진술로 그것을 할 것입니다 : DROP DATABASE ???

그리고 CREATE DATABASE ???


답변

여기에 스크립트 중 일부를 시도했지만 스키마에 테이블이 있기 때문에 작동하지 않았습니다. 그래서 다음을 정리했습니다. 이 스크립트는 스키마 목록을 가져 와서 순서대로 삭제합니다. 스키마에서 완전한 순서를 가지고 있는지 확인해야합니다. 순환 종속성이 있으면 실패합니다.

완전히 비어있는 데이터베이스를 백업하십시오. 모든 개체를 삭제하는 대신 백업 만 복원하십시오.
