Обсуждение: ecpg cursors and scope
I have two senarios about scoping and ecpg's parsing of cursor
declarations:
A) In seperate functions:
func1() {
exec sql declare test_cur for ...
}
func2() {
exec sql declare test_cur for ... /* same or different sql */
}
B) In an if:
if(...) {
exec sql declare test_cur for ...
} else {
exec sql declare test_cur for ... /* same or different sql */
}
These both yield "cursor test_cur already defined"
Is this by design? I seem to remember it working under 6.3.2, and this is
under 6.4.2
If I knew lex/yacc, I'd make an effort at a patch, alas my compilers class
of a few years ago made us parse the old fashioned way :) Does anyone know
of a work-around?
Thanks,

AFAIK teh standrad the cursor is valid in the scope of its module, i.e. the source file it's listed in. > Is this by design?
