除了@Ivan的回答外，还需要包括所有类型

    /* 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

试试这个

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'

试试这个…

USE DATABASE
GO
DECLARE @tname VARCHAR(150)
DECLARE @strsql VARCHAR(300)

SELECT @tname = (SELECT TOP 1 [name] FROM sys.objects WHERE [type] = 'U' and [name] like N'TableName%' ORDER BY [name])

WHILE @tname IS NOT NULL
BEGIN
    SELECT @strsql = 'DROP TABLE [dbo].[' + RTRIM(@tname) +']'
    EXEC (@strsql)
    PRINT 'Dropped Table : ' + @tname
    SELECT @tname = (SELECT TOP 1 [name] FROM sys.objects WHERE [type] = 'U' AND [name] like N'TableName%'  AND [name] > @tname ORDER BY [name])
END

这就是我所尝试的:

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

无论输出什么，它将打印，只是复制和粘贴在新的查询和按执行。 这将删除所有表。

DECLARE @name VARCHAR(255)
DECLARE @type VARCHAR(10)
DECLARE @prefix VARCHAR(255)
DECLARE @sql VARCHAR(255)

DECLARE curs CURSOR FOR
SELECT [name], xtype
FROM sysobjects
WHERE xtype IN ('U', 'P', 'FN', 'IF', 'TF', 'V', 'TR') -- Configuration point 1
ORDER BY name

OPEN curs
FETCH NEXT FROM curs INTO @name, @type

WHILE @@FETCH_STATUS = 0
BEGIN
-- Configuration point 2
SET @prefix = CASE @type
WHEN 'U' THEN 'DROP TABLE'
WHEN 'P' THEN 'DROP PROCEDURE'
WHEN 'FN' THEN 'DROP FUNCTION'
WHEN 'IF' THEN 'DROP FUNCTION'
WHEN 'TF' THEN 'DROP FUNCTION'
WHEN 'V' THEN 'DROP VIEW'
WHEN 'TR' THEN 'DROP TRIGGER'
END

SET @sql = @prefix + ' ' + @name
PRINT @sql
EXEC(@sql)
FETCH NEXT FROM curs INTO @name, @type
END

CLOSE curs
DEALLOCATE curs

尝试使用sql2012或更高版本，

这将有助于删除所选架构的所有对象

DECLARE @MySchemaName VARCHAR(50)='dbo', @sql VARCHAR(MAX)='';
DECLARE @SchemaName VARCHAR(255), @ObjectName VARCHAR(255), @ObjectType VARCHAR(255), @ObjectDesc VARCHAR(255), @Category INT;

DECLARE cur CURSOR FOR
    SELECT  (s.name)SchemaName, (o.name)ObjectName, (o.type)ObjectType,(o.type_desc)ObjectDesc,(so.category)Category
    FROM    sys.objects o
    INNER JOIN sys.schemas s ON o.schema_id = s.schema_id
    INNER JOIN sysobjects so ON so.name=o.name
    WHERE s.name = @MySchemaName
    AND so.category=0
    AND o.type IN ('P','PC','U','V','FN','IF','TF','FS','FT','PK','TT')

OPEN cur
FETCH NEXT FROM cur INTO @SchemaName,@ObjectName,@ObjectType,@ObjectDesc,@Category

SET @sql='';
WHILE @@FETCH_STATUS = 0 BEGIN    
    IF @ObjectType IN('FN', 'IF', 'TF', 'FS', 'FT') SET @sql=@sql+'Drop Function '+@MySchemaName+'.'+@ObjectName+CHAR(13)
    IF @ObjectType IN('V') SET @sql=@sql+'Drop View '+@MySchemaName+'.'+@ObjectName+CHAR(13)

    IF @ObjectType IN('U') SET @sql=@sql+'Drop Table '+@MySchemaName+'.'+@ObjectName+CHAR(13)

    --PRINT @ObjectName + ' | ' + @ObjectType
    FETCH NEXT FROM cur INTO @SchemaName,@ObjectName,@ObjectType,@ObjectDesc,@Category
END
CLOSE cur;    
DEALLOCATE cur;
SET @sql=@sql+CASE WHEN LEN(@sql)>0 THEN 'Drop Schema '+@MySchemaName+CHAR(13) ELSE '' END
PRINT @sql
--EXECUTE (@sql)
