Re: InstantDB: select madness


Sascha

What version of InstantDB are you using?

> SELECT * FROM Unit WHERE Unit.id IN (SELECT DISTINCT unitId FROM
> UnitOptions WHERE fieldname="targetArea" AND value="Berlin")
>
> So... The above doesn't work...

Do you get an exception, or does it return the wrong data? If the wrong data
then too much or too little or just the wrong value?

A script that creates the two tables, adds some data to illustrate the
problem would really help.

Regards

Pete
