[Lift] how to use BySql query

[pravin]

Hi,
I am new to lift .
I am using mapper framework.
i have table emp with name ,salary, location columns


 now i want to put query to find employee whose salary is less than
10000  and greater that 1000 and location is California.

For this i am using BySql query...as foolows ->

val emp_List = emp_details.findAll(BySql("salary between ? and ?,
1000,10000",IHaveValidatedThisSQL("pravin",""2009-08-03)));

but when i compileing this i get following error ->
