Question

我以前使用过以下的脚本，它可以正常工作：

    public const string application =
@"SET IDENTITY_INSERT Application ON
INSERT INTO Application(ApplicationId, Name, ModifiedDate) VALUES (1, 'x', getdate() );
INSERT INTO Application(ApplicationId, Name, ModifiedDate) VALUES (2, 'y', getdate() );
INSERT INTO Application(ApplicationId, Name, ModifiedDate) VALUES (3, 'z', getdate() );
SET IDENTITY_INSERT Application OFF
DBCC CHECKIDENT( 'Application', RESEED )";

现在我想执行DDL，但收到错误消息：

    public const string dropCreate =
        @"
        GO
        ALTER TABLE [dbo].[TestAccount] DROP CONSTRAINT [TestAccount_Application]
        GO
        DROP TABLE [dbo].[TestAccount]
        GO
        SET ANSI_NULLS ON
        GO        
        SET QUOTED_IDENTIFIER ON
        GO  
        CREATE TABLE [dbo].[TestAccount](
            [TestAccountId] [int] IDENTITY(1,1) NOT NULL,
            [Name] [nvarchar](35) NOT NULL,
            [ApplicationId] [int] NOT NULL,
            [RowVersion] [timestamp] NOT NULL,
            [ModifiedDate] [datetime] NOT NULL,
        PRIMARY KEY CLUSTERED 
        (
            [TestAccountId] ASC
        )WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
        ) ON [PRIMARY]
        GO
        ALTER TABLE [dbo].[TestAccount]  WITH CHECK ADD  CONSTRAINT [TestAccount_Application] FOREIGN KEY([ApplicationId])
        REFERENCES [dbo].[Application] ([ApplicationId])
        ON DELETE CASCADE
        GO       
        ALTER TABLE [dbo].[TestAccount] CHECK CONSTRAINT [TestAccount_Application]
        GO";
}

   HResult=-2146232060
   Message=Incorrect syntax near 'GO'.

我可以从C＃执行DDL吗？我使用的代码如下所示：

context.Database.ExecuteSqlCommand(TestAccountSQL.dropCreate);

GO不是SQL关键字;它由SQL Server Management Studio解释。

您需要将每个批处理作为单独的ExecuteSql调用发送，或使用SQL Server管理对象（SMO）。
