Обсуждение: Declare Cursor question again

Is the following legal:

if (<condition>) {
        exec sql declare cur cursor for
                select name, nr from table where nr < 10;
}
else {
        exec sql declare cur cursor for
                select name, nr from table where nr >= 10;
}


That is declaring one cursor in two different ways? Oracle cannot do that.
We can, though. Shall I disable this (and remove my last changes) or is this
a good feature (as I think it is) and we keep it? Only disadvantage is that
the declare tarnslates into a C statement and is not really a declaration
anymore.

On my Ingres box, the "declare cursor" statements could appear up in or
near the declarations portion of the program or routine. Wouldn't
associating this statement with executable code put limitations on
statement location which other systems (and perhaps the standard) do not
see?

Yes. In Oracle you can put it outside a function.
