Combining LINQ to SQL with Inline SQL

I am converting a project that i am in the process of developing to use LINQ to SQL. My problem is a scheduled process that syncs data with a 3rd party via several XML files. I am building one huge sql script to run at the end of the xml parsing process  to then execute in one trip to the database. A big part of this is a series of SQL "if" statements to see if something exists with some conditional logic and either update or insert a new record. From what i know LINQ doesn't handle conditional update or inserting without multiple database trips. I want to be able to get the generated SQL (select/insert/update/delete) using LINQ (without a trip to the DB) then mix it in with my own SQL for the conditional decision of insert or update. How do i get the generated SQL from LINQ for a select, insert, update or delete ?

Thanks
