Derived tables

Applies to ✅ Open Source Edition   ✅ Express Edition   ✅ Professional Edition   ✅ Enterprise Edition

A derived table is a nested SELECT in the FROM clause, i.e. it can be used as a table expression. As such, it works differently from a scalar subquery, which is a column expression.


SELECT nested.* FROM (
      SELECT AUTHOR_ID, count(*) books
        FROM BOOK
) nested
ORDER BY nested.books DESC
Table<?> nested =
    create.select(BOOK.AUTHOR_ID, count().as("books"))
