创建sqlserver的日志表
CREATE TABLE [dbo].[NLog](
[Id] [BIGINT] IDENTITY(1,1) NOT NULL,
[Application] [NVARCHAR](50) NOT NULL,
[Logged] [DATETIME] NOT NULL,
[Level] [NVARCHAR](50) NOT NULL,
[Message] [NVARCHAR](MAX) NOT NULL,
[Logger] [NVARCHAR](250) NULL,
[Callsite] [NVARCHAR](MAX) NULL,
[Exception] [NVARCHAR](MAX) NULL
) ON [PRIMARY] TEXTIMAGE_ON [PRIMARY]
