IEnumerable<T> Highway.Data.ObjectDataContext.ExecuteSqlQuery< T >	(	string	sql,
		params DbParameter[]	dbParams
	)

inline

Executes a SQL command and tries to map the returned datasets into an IEnumerable{T} The results should have the same column names as the Entity Type has properties

Template Parameters:
