c# - sql statement to Expression tree -

I'm wondering how to translate SQL strings on an exclusion tree. Currently, in SQL, the expression tree is translated into a SQL statement. How does the other side go? You will select the book name '<% p>

  from books, where book name'% 'and' year 'and' gt; 2008  

In an expression tree in C #?

update

Units in the unit framework is not sure whether the unit is SQL language if you want the same way.
