Re^2: array/hash - reference and dereference

O..my mistake..~~%hash~~ %ages Sorry.

%ages = ('Martin' => 0, 'Sharon' => 0, 'Rikke' => 0); #this way?

@insert = \%hash;

#at this point, what is the correct way to save the hash into an array
+?
$insert[0] = $ages->{‘Sharon’}; 
$insert[1]=$ages->{'Martin’};
%ages = ('Martin' => 28, 'Sharon' => 35, 'Rikke' => 29);
:
:    
$sqlquery -> execute(@insert);

My idea is: When the script start, I don't have the hash values. So,I want to create "pointer" points to the hash. And "save" the specific hash value into an array. Later, when the hash values are fetched, I can just run:

$sqlquery -> execute(@insert);

Please advise. Thanks.

It sounds like a lot more trouble than just making a `mkinsert()` function. `%ages = [...] # Finally filled in $sqlquery->execute(mkinsert(%ages));` [download] You could store references to the hash elements into the array instead. But you'd have to explicitly dereference them, and it would mostly serve to confuse people reading the code. Why not make it simple?	[reply] [d/l] [select]
