I have the following sql query
select * from hrwf.DEPT_DIV_UNIT_REP_NYU_T order by to_number(unit_no),to_number(div_no)

Is it possible to convert this into a named query. I could not find to_number in JPQL. Thanks for your time and help.

Regards
Kiran

There is no TO_NUMBER function in JPQL.

In EclipseLink (2.1) you can use the FUNC keyword to call a database function.

i.e.
ORDER BY FUNC('TO_NUMBER', rep.unit_no)

You could also use EclipseLink Expressions to define the query (which support toNumber()), or use a native SQL query.
