DROP PROCEDURE [dbo].[UploadByTableType];
GO

IF  EXISTS (SELECT * FROM sys.types st JOIN sys.schemas ss 
		ON st.schema_id = ss.schema_id 
	WHERE st.name = N'TStudentScore' AND ss.name = N'dbo')
DROP TYPE [dbo].[TStudentScore];
GO

CREATE TYPE [dbo].[TStudentScore] AS TABLE(
	[ID] [int] NULL,
	[Name] [varchar](250) NULL,
	[Score] [int] NULL
);
