Database API - Long values

[Shawn]

To say store a Long value, the only thing I can see to do is convert
it to a String.

I tried using INTEGER and then getting back a Long but it throws an
error about expecting an Object but getting a numeral.

Any suggestions on handling Longs? It's a key in the database so I'm
thinking a String isn't the best.

Nice work by the way. Your project dovetails nicely with GWT best
practices and using a command pattern!

Hi Shawn,

Thanks for your interest in the project!

Long types are particularly difficult to manage due to the lack of such a type in Javascript (JS numbers are *always* of type Float, 64 bit, which does not correspond to Java Longs which are 64-bit integers - see also http://code.google.com/webtoolkit/doc/latest/DevGuideCodingBasicsCompatibility.html).

Are the ID's to store really that large? Perhaps if you would use int types in GWT code, and map them to INTEGER SQL types, wouldn't that work?

Cheers,
Bart.

Thanks for the good work.

No they't like 1 or 2 or 3.

However, I can't say what big table on appengine will return to me.
It seems incremental and I'll likely not exceed an int value but ...
the id I get from appengine is a long and so I should code for any
value.

String is a hassle but ... my app isn't database intensive.

I wonder if the error would be ignored when really deployed. I need
to code it though in hosted mode. Will try a test of Long in
deployment later.
