Most of the times, when thinking about a table expression you're probably thinking about an actual table in your database schema. If you're using jOOQ's code generator, you will have all tables from your database schema available to you as type safe Java objects. You can then use these tables in SQL FROM clauses, JOIN clauses or in other SQL statements, just like any other table expression. An example is given here:
SELECT * FROM AUTHOR -- Table expression AUTHOR JOIN BOOK -- Table expression BOOK ON (AUTHOR.ID = BOOK.AUTHOR_ID)
create.select() .from(AUTHOR) // Table expression AUTHOR .join(BOOK) // Table expression BOOK .on(AUTHOR.ID.eq(BOOK.AUTHOR_ID)) .fetch();
