Fungsi PLACES_COUNT_PER_GEO mengambil array area geografis untuk ditelusuri
dan menampilkan tabel jumlah tempat per area. Misalnya, jika Anda menentukan
array kode pos sebagai area penelusuran, respons akan berisi tabel dengan
baris terpisah untuk setiap kode pos.
Karena fungsi PLACES_COUNT_PER_GEO menampilkan tabel, panggil fungsi tersebut menggunakan
klausa FROM.
Parameter input:
Wajib: geographiesParameter filter yang menentukan area penelusuran. Parameter
geographies mengambil array nilai yang ditentukan oleh jenis data
GEOGRAPHY
BigQuery, yang mendukung titik, linestring, dan poligon.
Opsional: Parameter filter tambahan untuk menyaring penelusuran Anda.
Retur:
Tabel dengan satu baris per area geografis. Tabel berisi kolom
geography (GEOGRAPHY), count (INT64), dan sample_place_ids
(ARRAY<STRING>) dengan sample_place_ids berisi hingga 250 ID tempat
untuk setiap area geografis.
Contoh: Hitung jumlah restoran di setiap county di New York City
Contoh ini membuat tabel jumlah restoran operasional per wilayah di New York City.
Contoh ini menggunakan set data publik BigQuery Data Biro Sensus Amerika Serikat untuk mendapatkan batas tiga wilayah di New York City: "Queens","Kings", "New York". Batas setiap county terdapat di kolom county_geom.
Contoh ini kemudian menggunakan fungsi
ST_SIMPLIFY
BigQuery untuk menampilkan versi county_geom yang disederhanakan. Fungsi ST_SIMPLIFY
menggantikan rantai tepi yang hampir lurus dengan satu tepi panjang.

For example, if you specify an\narray of zip codes as the search area, the response contains a table with a\nseparate row for each zip code.\n\nBecause the `PLACES_COUNT_PER_GEO` function returns a table, call it using\na `FROM` clause.\n\n- Input parameters:\n\n - **Required** : The `geographies`\n [filter parameter](/maps/documentation/placesinsights/experimental/filter-params) that specifies the search area. The\n `geographies` parameter takes an array of values defined by the BigQuery\n [`GEOGRAPHY`](https://cloud.google.com/bigquery/docs/reference/standard-sql/data-types#geography_type)\n data type, which supports points, linestrings, and polygons.\n\n - **Optional** : Additional [filter](/maps/documentation/placesinsights/experimental/filter-params) parameters to refine your\n search.\n\n- Returns:\n\n - A table with one row per geographic area. The table contains the columns `geography` (`GEOGRAPHY`) and `count` (`INT64`).\n\nExample: Calculate the number of restaurants in each county of New York City\n\nThis example generates a table of counts of operational restaurants per county\nin New York City.\n| **Note:** Because the response table contains a `geographies` field, you can visualize it using tools that support BigQuery `GEOGRAPHY` types. For an example of visualizing the results of a function, see [Visualize\n| results](#visualize_results). For more information and example on visualizing Places Insights results, see [Visualize query results](/maps/documentation/placesinsights/visualize-data).\n\nThis example uses the [United States Census Bureau\nData](https://console.cloud.google.com/marketplace/product/united-states-census-bureau/us-geographic-boundaries)\nBigQuery [public dataset](https://cloud.google.com/bigquery/public-data) to get\nthe boundaries for the three counties in New York City: \"Queens\",\"Kings\", \"New\nYork\". The boundaries of each county are contained in the `county_geom` column.\n\nThis example then uses the BigQuery\n[`ST_SIMPLIFY`](https://cloud.google.com/bigquery/docs/reference/standard-sql/geography_functions#st_simplify)\nfunction to return a simplified version of `county_geom`. The `ST_SIMPLIFY`\nfunction replaces nearly straight chains of edges with a single long edge. \n\n```googlesql\nDECLARE geos ARRAY\u003cGEOGRAPHY\u003e;\n\nSET geos = (SELECT ARRAY_AGG(ST_SIMPLIFY(county_geom, 100))\n FROM `bigquery-public-data.geo_us_boundaries.counties`\n WHERE county_name IN (\"Queens\",\"Kings\", \"New York\") AND state_fips_code = \"36\");\n\nSELECT * FROM `maps-platform-analytics-hub.sample_places_insights_us.PLACES_COUNT_PER_GEO`(\n JSON_OBJECT(\n 'geographies', geos,\n 'types', [\"restaurant\"],\n 'business_status', [\"OPERATIONAL\"]\n )\n);\n```\n\nThe response for the function:\n\nVisualize results\n\nThe following images show this data displayed in Looker Studio as a filled map,\nincluding the outline of each county:\n\nTo import your data into Looker Studio:\n\n1. Run the function above to generate the results.\n\n2. In the BigQuery results, click **Open in -\\\u003e Looker Studio**. Your results\n are automatically imported into Looker Studio.\n\n3. Looker Studio creates a default report page and initializes it with a title,\n table, and bar graph of the results.\n\n4. Select everything on the page and delete it.\n\n5. Click **Insert -\\\u003e Filled map** to add a filled map to your report.\n\n6. Under **Chart types -\\\u003e Setup** configure the fields as shown below::\n\n7. The filled map appears as above. You can optionally select **Chart types -\\\u003e\n Styles** to further configure the appearance of the map.\n\nFor more information and example on visualizing Places Insights results, see\n[Visualize query results](/maps/documentation/placesinsights/visualize-data)."]]
