in thread SQL::Abstract 'between' clause (about done)

To create the data you see in the POD with scalar assignements you would have to write this:

$where{user}= 'nwiger'; $where{completion_date}{-not_between}= ['2002-10-01', '2003-02-06'];

What would be a problem is if you used this as well:

$where{completion_date}= 5;

Because $where{completion_date} can't be pointer to a hash and scalar value at the same time. But nothing prevents you from storing further scalar values or hash pointers in $where{thingy} or $where{stuff} or $where{completion_date}{depperstuff}

A big help might be to watch Data::Dumper output of %where after you execute each of the above statements

    Thanks but isn't my code doing what your code does?
    $where{$colname}{'-between'} = [$from,$to]; #my code where{completion_date}{-not_between}= ['2002-10-01', '2003-02-06'];#yo +ur code
    I though $from and $to would work as they contain the right values.

      I'm not talking about your script. I just answered your implied question "I don't see where I can use this functionality with the two choices you mentioned to pick from" in your last post.

      After looking at your script I see that the problem is that when you call process("DATE1=20111111:20111112"), your script will execute the first 'unless' (which will put a scalar value into $where{DATE1}) and then execute the last 'if' block (which will try to put a reference into $where{DATE1}).

      The problem is evident from your script output (it prints "normal value: 20111111:20111112" and it shouldn't do that, right?). If you had put a few Data::Dumper statements into the subroutine it would have been even more conspicuous.

      So evidently Anonymous Monk was right

        Thank you so much, this clear explanation helped me a lot. Thank you!
