Esteban and Guille, I just realized that you gentlemen are the keepers of DBXTalk. Thank you for kindly corresponding with me. My hat's off to all of you for taking on this task. I have a somewhat grandeur goal for solving this problem. I would like to solve the problem rather than creating a work-around. I feel that the only way for Smalltalk to make a comeback is if it and the supporting tools just "work". If Pharo/GLORP supports MySql, then it should work, etc. etc - no work arounds. If the problem is in the OpenDBXDriver, then it would be nice if this could be fixed (since I have NO C-lang experience there is little that I can help with here) . If the problem is in OpenDBX libraries, then our options are more limited. If we need to modify GLORP to define the types in the mapping Descriptors and simply bypass the types provided by database drivers, then I can help with that. I'm willing to help what I can. My personal goal is to build a GUI interface for GLORP mapping. It would be nice to have this stuff working before I get started. (If the drivers/mappers don't really work, then why build a GUI mapping definition tool)?
