LISTAGG

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

The LISTAGG() aggregate function aggregates data into a string. It uses the WITHIN GROUP syntax.

SELECT
  listagg(ID) WITHIN GROUP (ORDER BY ID),
  listagg(ID, '; ') WITHIN GROUP (ORDER BY ID),
FROM BOOK
create.select(
         listagg(BOOK.ID).withinGroupOrderBy(BOOK.ID),
         listagg(BOOK.ID, "; ").withinGroupOrderBy(BOOK.ID))
      .from(BOOK).fetch();

Producing:

+------------+--------------+
| listagg    | listagg      |
+------------+--------------+
| 1, 2, 3, 4 | 1; 2; 3; 4   |
+------------+--------------+
