Re: Setting null to date field from Delphi.

[Terry Yapt <yapt(at)technovell(dot)com>]

Hello Alvaro and thanks for your answer...

I am using PostgreSQL 8.2.4 DB and I don't know if using previous odbc 
versions is an option.  (ie: Schemas might be a problem I think).

I agree with you that odbc 8.x.xx has a lot of "rare behaviours" and I 
am seriously thinking to get off odbc and buy direct access components 
VCL from MicroOlap or something similar:
MicroOlap: http://www.microolap.com/products/connectivity/postgresdac/

I am spending more time checking behaviours and looking for workarounds 
than developing software itself.

Do you know any other direct postgresql access for VCL  besides 
postgresDAC ?

Thanks.

Greetings from Spain...
