Question

my %Hash= (2012=> 1, 1982=>12, 2010=>0);

The has key and values need to be all on the same field name ‘time’ like an array

$mycollection->insert(
                     {
                         'field1' => $var1;
                         'field2' => $var2;
                          #right here I need to know how to add above hash key and values
                          # like below  
                          #'time': ["2012.1","1982.12","2010.0"]   
                     }
                   );

Any suggestions or ideas will be apprecieated. This can probably accomplished by doing series of update statements but I would like to accomplish this with one insert statement due to my requirement.

Answer 1

I suppose your %Hash variable is something like this:

my %Hash= (2012=> 1, 1982=>12, 2010=>0);

So your array “time” is build this way:

my @time = map { $_ . "." . $Hash{$_} } keys %Hash;

and finally:

$mycollection->insert({
   'field1' => $var1,
   'field2' => $var2,
   'time' => \@time   
});
