我会在两个语句中做到:DROP DATABASE ??

然后创建数据库??

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。

您必须首先禁用所有触发器和约束。

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

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

在此之后，您可以生成用于删除对象的脚本

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

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

执行生成的语句。

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

备份一个完全空的数据库。不需要删除所有对象，只需恢复备份。

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
