if you use C/C++ to program, there are several things you need to pay
attention to:
1. indicator. In informix, it does not matter, but in DB2, you must use
indicator for the null item
2. you can not use structure variable to access data in DB2, but you can
use it in Informix
3. Commit method can not be encapsulated in DB2
4. DB2 program need to be binded
5. Date format problem
If you use java, then not too many things for you to do.
not sure other languages.
