Re: [eclipselink-users] Help with having clause
|
Hello,
I'm not sure I understand. Are you trying to query data filtering on
the primary key? If so, can you not just use entitymanager.find(class,
19775)
or use the Id field in a where clause as in "SELECT data FROM Class data
WHERE data.id=19776"?
Having is used to filter data already filtered and grouped with the
Where and Group By clauses. If you are not grouping items, just use a
where clause.
Regards,
Chris

I would like to write a query that would retrieve only the middle row (ID =
19775) but I seem to be having some difficulty trying to locate the correct
SQL/JPAQL. Perhaps its my limited understanding but any assistance would be
greatly appreciated. I know that the HAVING clause should not be used
without a GROUP BY and I guess that is where my difficulty lies.
Thanks in advance.
