How to show content from a Google Maps address using Sequelize?

I looked for an information for several weeks. First, I'm using AngularJS 1.6 and ngMap module.

Here's what I'm doing:

• I'm using a search box (with ngMap autocomplete) in my Homepage:

  import htmlTemplate from './searchBox.html';
  
  export default {
  
    template: htmlTemplate,
  
    require: {
      parent: '^home'
    },
  
    controller: function controller(MapsService, $log) {
      'ngInject';
  
      const self = this;
  
      this.$onInit = () => {
        $log.info('searchBox component init');
        MapsService.loadGoogleApi().then(() => {
          this.loaded = true;
          this.onPlaceChanged = function onPlaceChanged() {
            const place = this.getPlace();
            if (place.geometry) {
              self.activity.lat = place.geometry.location.lat();
              self.activity.lng = place.geometry.location.lng();
            }
          };
        });
  

• Also, I'm using a component which shows activities. When I create an activity via my form, I fill an address field which uses autocomplete.

  <div class="input-field col s12">
      <i class="material-icons prefix">location_on</i>
            <input ng-if="$ctrl.loaded" places-auto-complete ng-model="$ctrl.activity.address" id="icon_prefix" type="text" on-place-changed="$ctrl.onPlaceChanged()"
              class="validate">
            <label for="icon_prefix">{{'ANNOUNCE.ADDRESS' | translate}}
      </label>
  

• I specified that addresses are converted in latitude / longitude.

  MapsService.loadGoogleApi().then(() => {
      this.loaded = true;
      this.onPlaceChanged = function onPlaceChanged() {
        const place = this.getPlace();
        if (place.geometry) {
          self.activity.lat = place.geometry.location.lat();
          self.activity.lng = place.geometry.location.lng();
        }
      };
    });
  

My question is:

How to show activities (by city) by making coincide the address of my search box and the address of my form?

Thanks a lot !

So... I finded my answer. It's necessary to add a stored procedure into the database and create a function which will allow to get back the data.
