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. |
