descriptor statements have the following shortcomings |
||||
|
||||
- up to now the only reasonable statement is |
||||
FETCH ... INTO SQL DESCRIPTOR <name> |
||||
no input variables allowed! |
||||
|
||||
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 |
