执行sqlce查询时发生异常

当我运行此脚本手册时,它正在工作,但当我使用实体框架在C中运行它时,我得到一个异常

db.Database.ExecuteSqlCommand(script); //Exception 

SQL脚本:

CREATE TABLE [Customers]
(
   [Id] INT NOT NULL IDENTITY (1,1),
   [Name] NVARCHAR(4000) NOT NULL,
   [Email] NVARCHAR(4000) NOT NULL,
   [Phone] NVARCHAR(4000) NOT NULL,
   [Address] NVARCHAR(4000) NOT NULL,
   [Suburb] NVARCHAR(4000) NOT NULL,
   [Postcode] NVARCHAR(4000) NOT NULL,
   [Number] INT NOT NULL
);
GO
ALTER TABLE [Customers] ADD CONSTRAINT [PK_Customers] PRIMARY KEY ([Id]);
Go
ALTER TABLE [Orders] Add [Customer_Id] INT;
GO

用“go”关键词摘录

“分析查询时出错。[令牌行号=12,令牌行偏移量=1,错误中的令牌=go]“

没有“go”关键字的异常

“分析查询时出错。[令牌行号=12,令牌行偏移量=1,错误中的令牌=更改]“
