PLACES_COUNT_PER_TYPE function

The PLACES_COUNT_PER_TYPE function returns a table of counts for each place type specified to the function. For example, if you search for the types doctor, hospital, and pharmacy the response contains a table with a separate row for each type.

Because the PLACES_COUNT_PER_TYPE function returns a table, call it using a FROM clause.

• Input parameters:

  • Required: The geography filter parameter that specifies the search area. The geography parameter takes a value defined by the BigQuery GEOGRAPHY data type, which supports points, linestrings, and polygons.

    For examples of using different types of search geographies, such as viewports and lines, see PLACES_COUNT function.

  • Required: The types filter parameter that specifies the place types to search for.

  • Optional: Additional filter parameters to refine your search.

• Returns:

• A table with one row per types value. The table contains the columns type (STRING), count (INT64), and sample_place_ids (ARRAY<STRING>) where sample_place_ids contains up to 250 place IDs for each type.

Example: Return count of restaurant, cafes, and bars

In this example, you search for all operational restaurant, cafe, and bars in the specified search area defined as a polygon in New York City.

The types parameter takes an array of STRING values specifying the place types to search for. For the complete list of possible values, see Table A and Table B at Places types.

This example also uses the BigQuery ST_GEOGFROMTEXT function to return a GEOGRAPHY value from a polygon.

DECLARE geo GEOGRAPHY;
SET geo = ST_GEOGFROMTEXT('''POLYGON((-73.985708 40.75773,-73.993324 40.750298,
                                      -73.9857 40.7484,-73.9785 40.7575,
                                      -73.985708 40.75773))''');  -- NYC viewport

SELECT * FROM `maps-platform-analytics-hub.sample_places_insights_us.PLACES_COUNT_PER_TYPE`(
  JSON_OBJECT(
      'types', ["restaurant", "cafe", "bar"],
      'geography', geo,
      'business_status', ['OPERATIONAL']

This function returns a table with three rows, one per type:
