Right, because arrays as as well unimplemented as are structs. I meant
something like this;
int *
get_var(void)
{
EXEC SQL BEGIN DECLARE SECTION;
static int myvar;
EXEC SQL END DECLARE SECTION;
EXEC SQL DECLARE mycur CURSOR FOR SELECT id INTO :myvar FROM a1 WHERE id = 1;
return (&myvar);
}

I don't think i buy into this. The variable is out of scope at the time open is
called. Why do you think this should work?

Eh, why not? We're talking about a bug/missing feature in the precompiler
itself. And the precompiler doesn't see this difference. I just pointed you to
one working example. Anyway I attached a modified test28.pgc that should work
in compatibility mode.
