Hi Richard,
What type of custom SQL do you want to use? Chances are someone on the
list has already written a custom qualifier that might do what you
need. Within Project Wonder's ERExtensions framework
(http;//wonder.sourceforge.net) there are 5 custom EOQualifiers if you
are looking for some examples. ERXInQualifier is probably the most
straight forward of the qualifiers.
Regards,
Max

Hello,
does anybody have an example of how to use custom SQL EOQualifiers ? I
thought
that an EOQualifier is an abstract EO concept which only supports
standard
operators like =, != etc. But the following text from the EO
documentation
"You must also use this auxiliary qualifier approach if the qualifier
can't be
executed in memory (for example, because it uses custom SQL or accesses
properties not in the object graph)" lets you conclude you could use
something
like Oracle's DECODE too which were quite useful for real projects.
