Having difficulty creating a stored procedure

I am trying to create stored procedure i Query analyzer in visual studio 2005. I am having
difficulty though. Whenever I press the execute button, here is the error message I get:

Msg 102, Level 15, State 1, Procedure MarketCreate, Line 21
Incorrect syntax near 'MarketName'.

Here is the stored procedure. Note that the very first column in named "MarketId" but I did not
include it in the stored procedure since it should be auto generated.

USE [StockWatch]
GO
/****** Object: StoredProcedure [dbo].[MarketCreate] Script Date: 08/28/2007 15:49:26 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO

CREATE PROCEDURE [dbo].[MarketCreate]

(
@.MarketCode nvarchar(20),
@.MarketName nvarchar(100),
@.LastUpdateDate nvarchar(2),
@.MarketDescription nvarchar(100)
)

AS
INSERT INTO Market
(
MarketCode
MarketName
LastUpdateDate
MarketDescription
)
VALUES
(
@.MarketCode
@.MarketName
@.LastUpdateUser
@.MarketDescription
)

You need to use comma's to separate the column names.

USE[StockWatch]

GO

/****** Object: StoredProcedure [dbo].[MarketCreate] Script Date: 08/28/2007 15:49:26 ******/

SET ANSI_NULLSON

GO

SET QUOTED_IDENTIFIERON

GO

CREATEPROCEDURE [dbo].[MarketCreate]

(

@.MarketCodenvarchar(20),

@.MarketNamenvarchar(100),

@.LastUpdateDatenvarchar(2),

@.MarketDescriptionnvarchar(100)

)

AS

INSERTINTO Market

(

MarketCode,

MarketName,

LastUpdateDate,

MarketDescription

)

VALUES

(

@.MarketCode,

@.MarketName,

@.LastUpdateUser,

@.MarketDescription

)

Handling Errors...

Hello to all,

On my webPage I have Used one SQLDataSource to access DataBase. Now whenever some error occures it shows error page by default. I am not able to catch Errors and tackle in my way...

Furthermore in this new structure of accessing DataBase even I do not know where to write Try... Catch...

Hey mistry,
this is the structure for Try ... Catch ... in SQL

Begin Try
-- e.g.
INSERT INTO a SELECT * FROM b
-- your actual code
End Try
Begin Catch
-- code for error handling
End Catch
