看来这个命令应该不带方巾

EXEC sp_msforeachtable 'drop table ?'

sp_msforeachtable在Azure SQL中不可用

对于Azure SQL:

此查询将删除外键约束

DECLARE @Name VARCHAR(200)
DECLARE @Constraint VARCHAR(300)
DECLARE @SQL VARCHAR(300)

SELECT @Name = (SELECT TOP 1 TABLE_NAME FROM INFORMATION_SCHEMA.TABLE_CONSTRAINTS WHERE constraint_catalog=DB_NAME() AND CONSTRAINT_TYPE = 'FOREIGN KEY' ORDER BY TABLE_NAME)

WHILE @Name is not null
BEGIN
    SELECT @Constraint = (SELECT TOP 1 CONSTRAINT_NAME FROM INFORMATION_SCHEMA.TABLE_CONSTRAINTS WHERE constraint_catalog=DB_NAME() AND CONSTRAINT_TYPE = 'FOREIGN KEY' AND TABLE_NAME = @Name ORDER BY CONSTRAINT_NAME)
    WHILE @Constraint IS NOT NULL
    BEGIN
        SELECT @SQL = 'ALTER TABLE [dbo].[' + RTRIM(@Name) +'] DROP CONSTRAINT [' + RTRIM(@Constraint) +']'
        EXEC (@SQL)
        PRINT 'Dropped FK Constraint: ' + @Constraint + ' on ' + @Name
        SELECT @Constraint = (SELECT TOP 1 CONSTRAINT_NAME FROM INFORMATION_SCHEMA.TABLE_CONSTRAINTS WHERE constraint_catalog=DB_NAME() AND CONSTRAINT_TYPE = 'FOREIGN KEY' AND CONSTRAINT_NAME <> @Constraint AND TABLE_NAME = @Name ORDER BY CONSTRAINT_NAME)
    END
SELECT @Name = (SELECT TOP 1 TABLE_NAME FROM INFORMATION_SCHEMA.TABLE_CONSTRAINTS WHERE constraint_catalog=DB_NAME() AND CONSTRAINT_TYPE = 'FOREIGN KEY' ORDER BY TABLE_NAME)
END
GO

这将从数据库中删除所有表

DECLARE @Name VARCHAR(200)
DECLARE @SQL VARCHAR(300)

SELECT @Name = (SELECT TOP 1 [name] FROM sysobjects WHERE [type] = 'U' AND category = 0 ORDER BY [name])

WHILE @Name IS NOT NULL
BEGIN
    SELECT @SQL = 'DROP TABLE [dbo].[' + RTRIM(@name) +']' /*here you can change schema if it is different from dbo*/
    EXEC (@SQL)
    PRINT 'Dropped Table: ' + @Name
    SELECT @Name = (SELECT TOP 1 [name] FROM sysobjects WHERE [type] = 'U' AND category = 0 AND [name] > @Name ORDER BY [name])
END
GO

禁食的方式是:

新的数据库图表 添加所有表 按Ctrl + A全选 右键单击“从数据库删除” 按Ctrl + S保存 享受

已接受的答案不支持Azure。它使用一个无文档的存储过程“sp_MSforeachtable”。如果您在运行时遇到“azure无法找到存储过程sp_msforeachtable”错误，或者只是想避免依赖未记录的特性(可以在任何时候删除或更改其功能)，那么请尝试下面的方法。

这个版本忽略了实体框架迁移历史表“__MigrationHistory”和“database_firewall_rules”，这是一个你没有权限删除的Azure表。

在Azure上进行了简单测试。一定要确保这对你的环境没有不良影响。

DECLARE @sql NVARCHAR(2000)

WHILE(EXISTS(SELECT 1 from INFORMATION_SCHEMA.TABLE_CONSTRAINTS WHERE CONSTRAINT_TYPE='FOREIGN KEY'))
BEGIN
    SELECT TOP 1 @sql=('ALTER TABLE ' + TABLE_SCHEMA + '.[' + TABLE_NAME + '] DROP CONSTRAINT [' + CONSTRAINT_NAME + ']')
    FROM INFORMATION_SCHEMA.TABLE_CONSTRAINTS
    WHERE CONSTRAINT_TYPE = 'FOREIGN KEY'
    EXEC(@sql)
    PRINT @sql
END

WHILE(EXISTS(SELECT * from INFORMATION_SCHEMA.TABLES WHERE TABLE_NAME != '__MigrationHistory' AND TABLE_NAME != 'database_firewall_rules'))
BEGIN
    SELECT TOP 1 @sql=('DROP TABLE ' + TABLE_SCHEMA + '.[' + TABLE_NAME + ']')
    FROM INFORMATION_SCHEMA.TABLES
    WHERE TABLE_NAME != '__MigrationHistory' AND TABLE_NAME != 'database_firewall_rules'
    EXEC(@sql)
    PRINT @sql
END

现货! !

你可以使用下面的查询从数据库中删除所有的表

EXEC sp_MSforeachtable @command1 = "DROP TABLE ?"

编码愉快!

在地对地导弹:

右键单击数据库 转到“任务” 点击“生成脚本” 在“选择对象”部分，选择“脚本整个数据库和所有数据库对象” 在“设置脚本选项”部分，单击“高级”按钮 在“脚本删除和创建”上切换“脚本创建”到“脚本删除”并按“确定” 然后，保存到文件，剪贴板，或新的查询窗口。 运行脚本。

现在，这将删除所有内容，包括数据库。确保删除您不希望删除的项目的代码。或者，在“选择对象”部分，而不是选择脚本整个数据库，只是选择你想要删除的项目。
