salida - retornar valor stored procedure sql server

Descarte todas las tablas, procedimientos almacenados, desencadenadores, restricciones y todas las dependencias en una declaración de SQL.

Question

¿Hay alguna forma en la que pueda limpiar una base de datos en SQl Server 2005 eliminando todas las tablas y eliminando procedimientos almacenados, desencadenadores, restricciones y todas las dependencias en una declaración SQL?

RAZÓN DE LA SOLICITUD:

¡Quiero tener un script de base de datos para limpiar una base de datos existente que no está en uso en lugar de crear otras nuevas, especialmente cuando tiene que enviar una solicitud a su administrador de base de datos y esperar un tiempo para hacerlo!

Answer 1

Accidentalmente ejecuté un script de inicio de db contra mi base de datos maestra esta noche. De todos modos, rápidamente me encontré con este hilo. Utilicé: exec sp_MSforeachtable ''DROP TABLE?'' Responda, pero tuve que ejecutarlo varias veces hasta que no se produjo el error (dependencias). Después de eso, me topé con algunos otros subprocesos y junté esto para eliminar todos los procedimientos y funciones almacenados.

DECLARE mycur CURSOR FOR select O.type_desc,schema_id,O.name
from
sys.objects O LEFT OUTER JOIN
sys.extended_properties E ON O.object_id = E.major_id
WHERE
O.name IS NOT NULL
AND ISNULL(O.is_ms_shipped, 0) = 0
AND ISNULL(E.name, '''') <> ''microsoft_database_tools_support''
AND ( O.type_desc = ''SQL_STORED_PROCEDURE'' OR O.type_desc = ''SQL_SCALAR_FUNCTION'' )
ORDER BY O.type_desc,O.name;
OPEN mycur;
DECLARE @schema_id int;
DECLARE @fname varchar(256);
DECLARE @sname varchar(256);
DECLARE @ftype varchar(256);
FETCH NEXT FROM mycur INTO @ftype, @schema_id, @fname;
WHILE @@FETCH_STATUS = 0
BEGIN
SET @sname = SCHEMA_NAME( @schema_id );
IF @ftype = ''SQL_STORED_PROCEDURE''
EXEC( ''DROP PROCEDURE "'' + @sname + ''"."'' + @fname + ''"'' );
IF @ftype = ''SQL_SCALAR_FUNCTION''
EXEC( ''DROP FUNCTION "'' + @sname + ''"."'' + @fname + ''"'' );
FETCH NEXT FROM mycur INTO @ftype, @schema_id, @fname;
END
CLOSE mycur
DEALLOCATE mycur
GO

Answer 2

Además de la respuesta de @ Ivan, todos los tipos deben incluirse

 /* Drop all Types */
DECLARE @name VARCHAR(128)
DECLARE @SQL VARCHAR(254)
SELECT @name = (SELECT TOP 1 [name] FROM sys.types where is_user_defined = 1 ORDER BY [name])
WHILE @name IS NOT NULL
BEGIN
SELECT @SQL = ''DROP TYPE [dbo].['' + RTRIM(@name) +'']''
EXEC (@SQL)
PRINT ''Dropped Type: '' + @name
SELECT @name = (SELECT TOP 1 [name] FROM sys.types where is_user_defined = 1 AND [name] > @name ORDER BY [name])
END
GO

Answer 3

Aquí encontré una nueva consulta para eliminar todos los sp, funciones y disparadores

declare @procName varchar(500)
declare cur cursor
for select [name] from sys.objects where type = ''p''
open cur
fetch next from cur into @procName
while @@fetch_status = 0
begin
exec(''drop procedure '' + @procName)
fetch next from cur into @procName
end
close cur
deallocate cur

Answer 4

Copia de seguridad de una base de datos completamente vacía. En lugar de eliminar todos los objetos, simplemente restaure la copia de seguridad.

Answer 5

Esto es lo que he intentado:

SELECT ''DROP TABLE ['' + SCHEMA_NAME(schema_id) + ''].['' + name + '']'' FROM sys.tables

Cualquiera que sea la salida que imprimirá, simplemente copie todo, pegue la nueva consulta y presione ejecutar. Esto borrará todas las tablas.

Answer 6

Estoy usando este script de Adam Anderson, actualizado para admitir objetos en otros esquemas que no sean dbo.

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
select @stmt = isnull( @stmt + @n, '''' ) +
''drop view ['' + schema_name(schema_id) + ''].['' + name + '']''
from sys.views
-- foreign keys
select @stmt = isnull( @stmt + @n, '''' ) +
''alter table ['' + schema_name(schema_id) + ''].['' + object_name( parent_object_id ) + ''] drop constraint ['' + name + '']''
from sys.foreign_keys
-- tables
select @stmt = isnull( @stmt + @n, '''' ) +
''drop table ['' + schema_name(schema_id) + ''].['' + name + '']''
from sys.tables
-- user defined types
select @stmt = isnull( @stmt + @n, '''' ) +
''drop type ['' + schema_name(schema_id) + ''].['' + name + '']''
from sys.types
where is_user_defined = 1
exec sp_executesql @stmt

Answer 7

Intenté algunas secuencias de comandos aquí, pero no funcionaron para mí, ya que tengo mis tablas en esquemas. Así que armé lo siguiente. Tenga en cuenta que esta secuencia de comandos toma una lista de esquemas, y luego cae en secuencia. Debe asegurarse de tener un orden completo en sus esquemas. Si hay dependencias circulares, entonces fallará.

Answer 8

Lo haría en dos frases: DROP DATABASE ???

y luego CREATE DATABASE ???

Answer 9

Lo mejor que puedes hacer es " Generar scripts para Drop "

Seleccione Base de datos -> Clic derecho -> Tareas -> Generar scripts - se abrirá el asistente para generar scripts

después de elegir los objetos en la opción establecer secuencias de comandos, haga clic en el botón Avanzado

• -> Establezca la opción ''Script para crear'' en verdadero (desea crear)
• -> Establezca la opción '' Script to Drop '' en true (desea soltar)
• -> Seleccione la casilla de verificación para seleccionar los objetos que desea crear script
• -> Seleccione la opción para escribir guión (Archivo, Nueva ventana, Portapapeles)

• Incluye objetos dependientes de forma predeterminada (y eliminará la restricción al principio)

  Ejecutar el guion

De esta manera podemos personalizar nuestro script.

Answer 10

Me parece una característica bastante peligrosa para mí. Si implementara algo como esto, me aseguraría de asegurarlo adecuadamente de una manera que no pueda ejecutar esto por accidente.

Como se sugirió antes, usted mismo podría hacer algún tipo de procedimiento almacenado. En SQL Server 2005, puede ver esta tabla del sistema para determinar y encontrar los objetos que desea eliminar.

select * from sys.objects

Answer 11

No hay una sola declaración que se pueda utilizar para lograr este objetivo.

Por supuesto, podría crearse un stored procedure que podría utilizar para realizar estas diversas tareas administrativas.

A continuación, puede ejecutar el procedimiento utilizando esta única instrucción.

Exec sp_CleanDatabases @DatabaseName=''DBname''

Answer 12

Para agregar a la respuesta de Ivan, también tuve la necesidad de eliminar todos los tipos definidos por el usuario, así que agregué esto al script:

/* Drop all user-defined types */
DECLARE @name VARCHAR(128)
DECLARE @SQL VARCHAR(254)
SELECT @name = (select TOP 1 [name] from sys.types where is_user_defined = 1)
WHILE @name IS NOT NULL
BEGIN
SELECT @SQL = ''DROP TYPE [dbo].['' + RTRIM(@name) +'']''
EXEC (@SQL)
PRINT ''Dropped Type: '' + @name
SELECT @name = (select TOP 1 [name] from sys.types where is_user_defined = 1)
END
GO

Answer 13

Para eliminar todas las tablas:

exec sp_MSforeachtable ''DROP TABLE ?''

Esto, por supuesto, eliminará todas las restricciones, desencadenadores, etc., todo menos los procedimientos almacenados.

Para los procedimientos almacenados, me temo que necesitará otro procedimiento almacenado almacenado en el master .

Answer 14

Para eliminar todos los objetos en oracle:

1) dinámico

DECLARE
CURSOR IX IS
SELECT * FROM ALL_OBJECTS WHERE OBJECT_TYPE =''TABLE''
AND OWNER=''SCHEMA_NAME'';
CURSOR IY IS
SELECT * FROM ALL_OBJECTS WHERE OBJECT_TYPE
IN (''SEQUENCE'',
''PROCEDURE'',
''PACKAGE'',
''FUNCTION'',
''VIEW'') AND OWNER=''SCHEMA_NAME'';
CURSOR IZ IS
SELECT * FROM ALL_OBJECTS WHERE OBJECT_TYPE IN (''TYPE'') AND OWNER=''SCHEMA_NAME'';
BEGIN
FOR X IN IX LOOP
EXECUTE IMMEDIATE(''DROP ''||X.OBJECT_TYPE||'' ''||X.OBJECT_NAME|| '' CASCADE CONSTRAINT'');
END LOOP;
FOR Y IN IY LOOP
EXECUTE IMMEDIATE(''DROP ''||Y.OBJECT_TYPE||'' ''||Y.OBJECT_NAME);
END LOOP;
FOR Z IN IZ LOOP
EXECUTE IMMEDIATE(''DROP ''||Z.OBJECT_TYPE||'' ''||Z.OBJECT_NAME||'' FORCE '');
END LOOP;
END;
/

2) Estático

 SELECT ''DROP TABLE "'' || TABLE_NAME || ''" CASCADE CONSTRAINTS;'' FROM user_tables
union ALL
select ''drop ''||object_type||'' ''|| object_name || '';'' from user_objects
where object_type in (''VIEW'',''PACKAGE'',''SEQUENCE'', ''PROCEDURE'', ''FUNCTION'')
union ALL
SELECT ''drop ''
||object_type
||'' ''
|| object_name
|| '' force;''
FROM user_objects
WHERE object_type IN (''TYPE'');

Answer 15

Prueba esto

Select ''ALTER TABLE '' + Table_Name +'' drop constraint '' + Constraint_Name from Information_Schema.CONSTRAINT_TABLE_USAGE
Select ''drop Procedure '' + specific_name from Information_Schema.Routines where specific_name not like ''sp%'' AND specific_name not like ''fn_%''
Select ''drop View '' + table_name from Information_Schema.tables where Table_Type = ''VIEW''
SELECT ''DROP TRIGGER '' + name FROM sysobjects WHERE type = ''tr''
Select ''drop table '' + table_name from Information_Schema.tables where Table_Type = ''BASE TABLE''

END

Answer 18

Primero debes deshabilitar todos los triggers y constraints .

EXEC sp_MSforeachtable @command1="ALTER TABLE ? NOCHECK CONSTRAINT ALL"
EXEC sp_MSforeachtable @command1="ALTER TABLE ? DISABLE TRIGGER ALL"

Después de eso, puede generar los scripts para eliminar los objetos como

SELECT ''Drop Table ''+name FROM sys.tables WHERE type=''U'';
SELECT ''Drop Procedure ''+name FROM sys.procedures WHERE type=''P'';

Ejecutar las sentencias generadas.
