Re: Status of adding BOOLEAN-type

[Rick Hillegas <Ri...@Sun.COM>]

Hi  Kristian,

I have given up on re-enabling the BOOLEAN datatype in the near term, 
for the following reasons:

1) I can't see when or whether the BOOLEAN datatype will make it into 
the DRDA spec. After 9 months, the spec's governing body has failed to 
revive. There seems to be very little industry interest in funding the 
continuation of DRDA spec work.

2) The existing (10.1) behavior of Derby BOOLEAN violates the ANSI 
casting rules. See DERBY-887. Fixing these casts will break Derby's ODBC 
metadata and for that reason we suspect that customer applications will 
break also. This appears to be the kind of compatibility issue which 
requires a major rather than a minor release of Derby. I see the 
following options:

 a) Expose a BOOLEAN datatype which does not conform to the ANSI spec.
 b) Break existing customer applications.
 c) Wait until the next major release of Derby before re-enabling BOOLEAN.

My vote would be for (2c) but I don't sense enough enthusiasm for 
BOOLEAN to justify a major release in the near term.

Regards,
-Rick

Hi Rick,

Don't you mean you'll back out the current BOOLEAN work from 10.2
*after* it has been branched?

Or do you think we should give up completely due to the issues with
the DRDA spec committee that you mentioned?
