public interface SelectGroupByStep<R extends Record> extends SelectHavingStep<R>
Select
's DSL API when selecting generic
Record
types.
Example:
Its equivalent in jOOQ
-- 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
Refer to the manual for more details

XYZ*Step
types directly from client code
It is usually not recommended to reference any XYZ*Step
types
directly from client code, or assign them to local variables. When writing
dynamic SQL, creating a statement's components dynamically, and passing them
to the DSL API statically is usually a better choice. See the manual's
section about dynamic SQL for details: https://www.jooq.org/doc/latest/manual/sql-building/dynamic-sql.
Drawbacks of referencing the XYZ*Step
types directly:
Modifier and Type | Method and Description |
---|---|
SelectHavingStep<R> |
groupBy(Collection<? extends GroupField> fields)
Add a
GROUP BY clause to the query
Calling this with an empty argument list will result in an empty
GROUP BY () clause being rendered. |
SelectHavingStep<R> |
groupBy(GroupField... fields)
Add a
GROUP BY clause to the query
Calling this with an empty argument list will result in an empty
GROUP BY () clause being rendered. |
