Subject drda datatypes
Date Mon, 15 Aug 2005 18:40:40 GMT
According to the January 2004 rev of the DRDA spec, DRDA does not 
support the following SQL datatypes which we want to support or already 
partially support:


How do we move forward to support these types? Here are some 
suggestions. What do you think?

1) Wait until the spec owner (Open Group) adds these to a future rev of 
DRDA. We would lobby Open Group to do this.

2) Create our own, custom-rev of DRDA which supports these datatypes. 
Jim Gray seems to think that the spirit of DRDA allows these 
customizations (see the following paper: 
research.microsoft.com/~gray/papers/SqlAccessVsDrda.doc ). In this 
scheme, Derby 10.2 clients and servers would ship with support for the 
new datatypes. 10.2 servers would have to do something creative when 
10.1 or db2jcc clients accessed these datatypes.

3) Support some other data interchange format, either alongside or in 
place of DRDA.
