If that is what w3cschools are suggesting as an insert, then they need
to revise the lessons ;-)

The above is a select statement, not an insert statement

A query like the following works fine with the default hsqldb engine
(embedded hsqldb) ODB :

select ID, 'TauxFacturation', NOW() from "Employés"

LibreOffice uses hsqldb 1.8 as the default embedded db engine


Other db engines use their own forms of SQL syntax.
