DataType problem in access database

I am creating a table in access database using OdbcConnection class as I am using DSN but I was unable to create table. An error is generated "Syntax error in field initilizer." I am using c# 3.5.
 
Query which I had written for creating table is
 
create table [tblEmployee] ([ID] long not null , [EmployeeSalary] decimal null)
 
I think problem is with decimal datatype in Odbc driver but when I am using OleDbConnection then no problem arises.
