如果你不想输入，你可以这样创建语句:

USE Databasename

SELECT  'DROP TABLE [' + name + '];'
FROM    sys.tables

然后复制并粘贴到一个新的SSMS窗口中以运行它。

不是一个问题，但还是很简短和甜蜜:

-- Disable all referential integrity constraints
EXEC sp_msforeachtable 'ALTER TABLE ? NOCHECK CONSTRAINT ALL'
GO

-- Drop all PKs and FKs
declare @sql nvarchar(max)
SELECT @sql = STUFF((SELECT '; ' + 'ALTER TABLE ' + Table_Name  +'  drop constraint ' + Constraint_Name  from Information_Schema.CONSTRAINT_TABLE_USAGE ORDER BY Constraint_Name FOR XML PATH('')),1,1,'')
EXECUTE (@sql)
GO

-- Drop all tables
EXEC sp_msforeachtable 'DROP TABLE ?'
GO

试试这个

DROP DATABASE database_name;
CREATE DATABASE database_name;

这将删除数据库并创建一个具有相同名称的新数据库

你也可以使用下面的脚本删除所有内容，包括以下内容:

我知道这个问题很古老，但每次我需要这个代码..顺便说一下，如果你有表、视图、函数和过程，你可以通过这个脚本删除它们。 为什么我要发布这个脚本?因为如果你删除了所有的表，你就需要删除所有的视图，如果你有函数和过程，你也需要删除它 我希望它能帮助到别人

DECLARE @sql NVARCHAR(max)=''

 SELECT @sql += ' Drop table ' + QUOTENAME(TABLE_SCHEMA) + '.'+ QUOTENAME(TABLE_NAME) 
+ '; '
FROM   INFORMATION_SCHEMA.TABLES
WHERE  TABLE_TYPE = 'BASE TABLE'

Exec Sp_executesql @sql


 DECLARE @sql VARCHAR(MAX) = ''
    , @crlf VARCHAR(2) = CHAR(13) + CHAR(10) ;

 SELECT @sql = @sql + 'DROP VIEW ' + QUOTENAME(SCHEMA_NAME(schema_id)) + '.' + 
 QUOTENAME(v.name) +';' + @crlf
 FROM   sys.views v

 PRINT @sql;
 EXEC(@sql);

 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

  Declare @sql NVARCHAR(MAX) = N'';

    SELECT @sql = @sql + N' DROP FUNCTION ' 
               + QUOTENAME(SCHEMA_NAME(schema_id)) 
               + N'.' + QUOTENAME(name)
    FROM sys.objects
  WHERE type_desc LIKE '%FUNCTION%';

   Exec sp_executesql @sql
  GO

使用以下脚本删除所有约束:

DECLARE @sql NVARCHAR(max)=''

SELECT @sql += ' ALTER TABLE ' + QUOTENAME(TABLE_SCHEMA) + '.'+ QUOTENAME(TABLE_NAME) +    ' NOCHECK CONSTRAINT all; '
FROM   INFORMATION_SCHEMA.TABLES
WHERE  TABLE_TYPE = 'BASE TABLE'

Exec Sp_executesql @sql

然后执行以下命令删除所有表:

select @sql='';

SELECT @sql += ' Drop table ' + QUOTENAME(TABLE_SCHEMA) + '.'+ QUOTENAME(TABLE_NAME) + '; '
FROM   INFORMATION_SCHEMA.TABLES
WHERE  TABLE_TYPE = 'BASE TABLE'

Exec Sp_executesql @sql

这为我在Azure SQL数据库'sp_msforeachtable'不可用!
