poll on jcr query usage

Hi all,

my apologies for cross posting, but I'd like to get as many responses as
possible from any kind of jackrabbit users on this topic.

I'd like to know what the preferred query language is that you are using, just
to get a feeling where further development should go regarding query support in
jackrabbit and JCR in general.

[ ] I primarily use XPath
[ ] I primarily use SQL
[ ] I use both XPath and SQL

and on a related topic:

If there was an API to construct a query I would ...

[ ] ... use it /instead/ of the existing XPath or SQL languages.
[ ] ... use it only for occasionally.
[ ] ... not use it at all.

Thank you for participating.

regards
marcel

Hi Marcel,
[ ] I primarily use XPath
[ ] I primarily use SQL
[X] I use both XPath and SQL

[X] ... use it /instead/ of the existing XPath or SQL languages.
[ ] ... use it only for occasionally.
[ ] ... not use it at all.

On the 2nd point, especially true if the construction of the query provided
performance benefits in terms of parameter binding etc.

Regards,
Shaun.

I would like to add that it would be great to have extended XPATH
support, will all the axis and functions implemented...

If there was an API to construct a query I would ...
[X] ... use it /instead/ of the existing XPath or SQL languages.
[ ] ... use it only for occasionally.
[ ] ... not use it at all.

Also, even if the latter API has optimizations that make
query reuse faster than with XPath, it would of course be
useful if it allowed you to recover the equivalent XPath (or SQL)
queries, effectively providing an XPath formulation toolkit.

Oh, yes, I have to change my answer:

[X] I primarily use Full XPath (based on Jaxen in a custom SearchIndex)
[ ] I primarily use XPath
[ ] I primarily use SQL
[ ] I use both XPath and SQL

Although our implementation [1] does not include the custom functions that
the JCR standard adds to XPath (like element(*, nt:file)), it does have full
Xpath 1.0 support, including child axis predicates.
