No support to nulling parameters

[GoogleCodeExporter]

Take the following query..


var name = "test";
var sql = new SqlLam<User>();
sql.Where(x => x.UserName == name).Or(x => name == null);
or
var sql = new SqlLam<User>(x => x.UserName == name || name == null);


This causes a System.StackOverflowException, what it should return is
"SELECT * FROM User WHERE Username = @Param1 OR @Param1 IS NULL"
