Interface SelectFromStep
- All Superinterfaces:
- Adapter, Attachable, FieldLike, FieldProvider, Query, QueryPart, ResultQuery<Record>, Select<Record>, SelectConnectByStep, SelectFinalStep, SelectForUpdateStep, SelectGroupByStep, SelectHavingStep, SelectLimitStep, SelectOrderByStep, SelectWhereStep, Serializable, TableLike<Record>
- All Known Subinterfaces:
- SelectSelectStep
public interface SelectFromStep
- extends SelectWhereStep
This type is used for the Select
's DSL API when selecting generic
Record
types.
Example:
-- get all authors' first and last names, and the number
-- of books they've written in German, if they have written
-- more than five books in German in the last three years
-- (from 2011), and sort those authors by last names
-- limiting results to the second and third row
SELECT T_AUTHOR.FIRST_NAME, T_AUTHOR.LAST_NAME, COUNT(*)
FROM T_AUTHOR
JOIN T_BOOK ON T_AUTHOR.ID = T_BOOK.AUTHOR_ID
WHERE T_BOOK.LANGUAGE = 'DE'
AND T_BOOK.PUBLISHED > '2008-01-01'
GROUP BY T_AUTHOR.FIRST_NAME, T_AUTHOR.LAST_NAME
HAVING COUNT(*) > 5
ORDER BY T_AUTHOR.LAST_NAME ASC NULLS FIRST
LIMIT 2
OFFSET 1
FOR UPDATE
OF FIRST_NAME, LAST_NAME
NO WAIT
Its equivalent in jOOQ
create.select(TAuthor.FIRST_NAME, TAuthor.LAST_NAME, create.count())
.from(T_AUTHOR)
.join(T_BOOK).on(TBook.AUTHOR_ID.equal(TAuthor.ID))
.where(TBook.LANGUAGE.equal("DE"))
.and(TBook.PUBLISHED.greaterThan(parseDate('2008-01-01')))
.groupBy(TAuthor.FIRST_NAME, TAuthor.LAST_NAME)
.having(create.count().greaterThan(5))
.orderBy(TAuthor.LAST_NAME.asc().nullsFirst())
.limit(2)
.offset(1)
.forUpdate()
.of(TAuthor.FIRST_NAME, TAuthor.LAST_NAME)
.noWait();
