Hope this helps Despite json_autoconv_numbers = 1, the type conversion solved my problem:
code :
mysql> SELECT integer(subsite_min_cnt.85) < integer(version_content_cnt.10008) as c, subsite_min_cnt.85, version_content_cnt.10008 
       FROM mobile_collection where c > 0;
+------+--------------------+---------------------------+
| c    | subsite_min_cnt.85 | version_content_cnt.10008 |
+------+--------------------+---------------------------+
|    1 | 3                  | 5                         |
+------+--------------------+---------------------------+

VS2010 Profiler comparison report baseline/comparison values

VS2010 Profiler comparison report baseline/comparison values

it fixes the issue Are the two reports you are comparing from a website project? If so it is likely that the dynamically generated module name is different each time you collect a profile. Since we use both the function name and module name to determine if functions match, this would explain why Page_Load shows up as two different rows.
You can check this by opening up each report in Visual Studio and navigating to the 'Modules' view to determine what the module name is for Page_Load in each report.

seems to work fine You need to compare with all the items in the location1 array or you can restructure your JSON to make the comparison easier
code :
json = {
 'carset' : {
    'location-cars' : {
      'volvo'  : 5,
      'mazda'  : 7,
      'toyota' : 10
    }
  }
}

function addCar(cars, car) {
  var theCar = cars[car];
   if ( theCar == undefined ) {
      cars[car] = 1;
   } else {
      cars[car] = theCar + 1;
   }
   return cars[car];
}

addCar(json.carset['location-cars'], 'volvo');

wish helps you I have this JSON. I need to first compare values in teams with values in html_content.position[i] where i should be a loop var, and then if comparison returns true then get the value. See this example: , The problem is with this code you are using:
code :
html_content.position[0][0].toLowerCase() = "navegantes";
var matches = [];

for(var teamName in json.teams)
{
   for(var i = 0, len = json.html_content.position.length; i < len; i++)
   {
      if(json.html_content.position[i][0][0].toLowerCase() === teamName.toLowerCase())
      {
          // found a match. do something with it..
          matches[matches.length] = {Name: teamName, Value: json.teams[teamName]};
          break;
      }
   }
}
var json = {
      "response":true,
      "teams":{

will be helpful for those in need Is comparison of uint8_t values in 64-bit Intel architecture slower than comparison of uint32_t? In particular, in Visual Studio C++. , On my machine it's too close to call:
code :
#include <cstdint>
#include <vector>
#include <random>
#include <iostream>
#include <chrono>
#include <algorithm>
#include <numeric>

template<class T>
std::vector<T> generate_test_data(std::size_t seed)
{
    auto v = std::vector<T>(20000000);
    std::default_random_engine eng(seed);
    std::uniform_int_distribution<T> dist(-127, 127);
    std::generate(std::begin(v), std::end(v),
                  [&eng, &dist] {
                      return dist(eng);
                  });
    return v;
}

auto inc_if_under_zero = [](int count, auto val) {
    return (val < 0) ? count + 1 : count;
};

int main()
{
    std::random_device rd;
    auto seed = rd();
    auto int_data = generate_test_data<std::int32_t>(seed);
    auto byte_data = generate_test_data<std::int8_t>(seed);

    auto t0 = std::chrono::high_resolution_clock::now();

    auto less_zero_32 = std::accumulate(std::begin(int_data),
                                        std::end(int_data),
                                        0,
                                        inc_if_under_zero);
    auto t1 = std::chrono::high_resolution_clock::now();

    auto less_zero_8 = std::accumulate(std::begin(byte_data),
                                       std::end(byte_data),
                                       0,
                                       inc_if_under_zero);

    auto t2 = std::chrono::high_resolution_clock::now();

    auto int_time = std::chrono::duration_cast<std::chrono::microseconds>(t1-t0).count();
    auto byte_time = std::chrono::duration_cast<std::chrono::microseconds>(t2-t1).count();

    std::cout << "totals    : " << less_zero_32 << ", " << less_zero_8 << std::endl;
    std::cout << "int time  : " << int_time << "us" << std::endl;
    std::cout << "byte time : " << byte_time << "us" << std::endl;
}
totals    : 9962877, 9962877

Does that help I know its been a while but I was just chugging on something similar (using wild cards to query json datatypes) and thought I'd share what I found.
Firstly, this was a huge point in the right direction: http://schinckel.net/2014/05/25/querying-json-in-postgres/
