Its equivalent in jOOQ

-- 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

NOTE: When inserting plain SQL into jOOQ objects, you must guarantee syntax integrity. You may also create the possibility of malicious SQL injection. Be sure to properly use bind variables and/or escape literals when concatenated into SQL clauses!

DSL.table(String, QueryPart...)
@Support SelectFromStep<R> hint(java.lang.String hint)
Example:
DSLContext create = DSL.using(configuration);
create.select(field1, field2)
.hint("/*+ALL_ROWS*/")
.from(table1)
.fetch();
You can also use this clause for any other database, that accepts hints
or options at the same syntactic location, e.g. for MySQL's
SQL_CALC_FOUND_ROWS
option:
create.select(field1, field2)
.hint("SQL_CALC_FOUND_ROWS")
.from(table1)
.fetch();
The outcome of such a query is this:
SELECT [hint] field1, field2 FROM table1
For SQL Server style table hints, see Table.with(String)
Table.with(String)
,
SelectQuery.addHint(String)
