- Synced preproc.y with gram.y.
Wed Nov 14 11:50:27 CET 2001
- Added several patches by Christof Petig <christof.petig@wtal.de>.
- Set ecpg version to 2.9.0.
- Set library version to 3.3.0.
src/interfaces/ecpg/README.dynSQL
View file @ 32a4c300
descriptor statements have the following shortcomings
- up to now the only reasonable statement is
FETCH ... INTO SQL DESCRIPTOR <name>
no input variables allowed!
- input descriptors (USING DESCRIPTOR <name>) are not supported
Reason: to fully support dynamic SQL the frontend/backend communication
should change to recognize input parameters.
Since this is not likely to happen in the near future and you
can cover the same functionality with the existing infrastructure
I'll leave the work to someone else.
- string buffer overflow does not always generate warnings
(beware: terminating 0 may be missing because strncpy is used)
:var=data sets sqlwarn accordingly (but not indicator)
- char variables pointing to NULL are not allocated on demand
- string truncation does not show up in indicator
(using s[n]printf), I'll leave the work to someone else.
