Hi Ken,

Thanks for a quick response.

Note: you haven't supplied data that matches your original 12:15 or subsequent any:20 I've made an additional change in order to get some output.

indeed I have two scripts, one that does time based as you had given me, and the other one that takes in file as an input and then parses json. This script (in the above post) takes input (as json output from a webpage logged to the file) and parses it.

I want to attach the file but I am not sure how I can do that. I tried it as above but it gives me the foll. error:

use strict; use warnings; use Time::Local; use JSON; use File::Read; my $jsonc = read_file ('H:\Work\perl\latest\Scripts\logs\json.txt'); { local $/ = "}\n"; while ($jsonc) { s/\n[+]?//gm; my $data = decode_json $_; for (@{$data->{aaData}}) { #my print/parse function } } }
What does having while(<DATA>) do? Does it read till end of the _DATA_ ? if so is it correct that in my above case I do a while($jsonc)? I understood the substitution part, thanks a lot. However, in my case when I parse my file I get the below error:
c:\perl>perl json.pl Use of uninitialized value $_ in substitution (s///) at get.pl line 14 +. malformed JSON string, neither array, object, number, string or atom, +at character offset 0 (before "(end of string )") at get.pl line 15.
Content of json.txt looks pretty much same as what you have mentioned above in the _DATA_ section.And I can clearly see that the end of first json block has a "]]}\n". So its supposed to work as you mentioned.

    [erix]: then you might as well send that patch to the DBIC guys :)
    [Corion]: erix: Yeah, I just found that it has no documentation at all on how to circumvent/ eliminate "1+n SELECTs" by building a local hash... I guess I have to make ->has_many do the hash lookup instead of doing the SQL query. But as the problem ...
    [Corion]: ... has only manifested itself so far through the puzzled questions of other bystanders, I won't go deeper at this time. But the DBIx::Class documentation could well do with a document on how to make "it" (that is, ORMs in general) faster ;)
    [Corion]: I find that DBIx::Class, like most ORMs makes things easy until they become performance critical and then makes it horribly hard to change things because the design is highly inflexible if you don't already know about the problems of 1+n :-/
    [choroba]: that's why I don't like similar libraries. They pretend you don't have to learn SQL, but in the end, you have to learn how SQL plus to overcome their own limitations
    [Corion]: "Just write the proper SQL beforehand" is of course the appropriate solution, but if you did that, you wouldn't/couldn't use DBIx::Class either. At least not in an obvious (to me) way.
