Collations
Applies to ✅ Open Source Edition ✅ Express Edition ✅ Professional Edition ✅ Enterprise Edition
Many databases support "collations", which defines the sort order on character data types, such as VARCHAR.
Such databases usually allow for specifying:
- System-wide default collations
- Session-wide default collations
- Per-table specific default collations
- Per-column specific default collations
- Per-usage specific collation
The actual implementation is vendor-specific, including the way the above defaults override each other.
To accommodate most use-cases jOOQ 3.11 introduced the org.jooq.Collation type, which can be attached to a org.jooq.DataType through DataType.collate(Collation), or to a org.jooq.Field through Field.collate(Collation), for example:
SELECT * FROM book ORDER BY title COLLATE utf8_bin
create.selectFrom(BOOK)
.orderBy(BOOK.TITLE.collate("utf8_bin"))
.fetch();
