1.16 Oracle SpatialでのJSONおよびGeoJSONのサポート

Spatialでは、JSONおよびGeoJSONオブジェクトを使用したJSON (JavaScript Object Notation)形式の地理データの格納、索引付けおよび管理がサポートされます。

リリース18.1で導入されたJSONのサポートにより、以前のリリースで使用可能な制限付きのGeoJSONのサポートは大幅に拡張されており、2Dおよび3D、ソリッド、面、LRSジオメトリを含む広範囲のジオメトリがサポートされています。SpatialのGeoJSON固有のAPIは引き続きサポートされますが、より包括的なJSONサポートの使用をお薦めします。

1.16.1 Oracle SpatialでのJSONのサポート

Spatialでは、JSONオブジェクトを使用したJSON (JavaScript Object Notation)形式の地理データの格納、索引付けおよび管理がサポートされます。

Oracle SpatialのSDO_GEOMETRYオブジェクトをJSONジオメトリ・オブジェクトに変換したり、JSONジオメトリ・オブジェクトをSDO_GEOMETRYオブジェクトに変換して返すことができます。

SpatialでのJSONのサポートには次のものが含まれます。

  • SDO_UTIL.TO_JSON: SDO_GEOMETRYオブジェクトをCLOB形式のJSONオブジェクトに変換します。

  • SDO_UTIL.TO_JSON_VARCHAR: SDO_GEOMETRYオブジェクトをVARCHAR2形式のJSONオブジェクトに変換します。

  • SDO_UTIL.FROM_JSON: JSONオブジェクト(CLOBまたはVARCHAR2形式)をSDO_GEOMETRYオブジェクトに変換します。このファンクションは、GeoJSONオブジェクトをSDO_GEOMETRYオブジェクトに変換することもできます。

例1-3 SpatialでのJSONのサポート

この例では、Oracle SpatialでJSONサポートを使用した操作をいくつか示します。この例では、JSON列(CLOB、JSONおよびVARCHAR2データ型)とSDO_GEOMETRY列を含む単純な表を作成し、サンプル・データを挿入し、単純な問合せを実行し、空間索引を作成し、SDO_WITHIN_DISTANCE演算子を使用して問合せを実行します。

例では、IS JSON Oracle SQL条件をCREATE TABLE文内のチェック制約として使用して、CLOB列にJSONデータが含まれていることを確認します。詳細は、『Oracle Database JSON開発者ガイド』を参照してください。

例には、説明のコメントとSQL文の出力が含まれます。(出力は、簡単に読むことができるように、再フォーマットされています。)

1.16.2 Oracle SpatialでのGeoJSONのサポート

Oracle Spatialでは、GeoJSONオブジェクトを使用したJSON (JavaScript Object Notation)形式の地理データの格納、索引付けおよび管理がサポートされます。

SpatialのSDO_GEOMETRYオブジェクトをGeoJSONオブジェクトに、また、GeoJSONオブジェクトをSDO_GEOMETRYオブジェクトに変換できます。空間演算子、ファンクションおよび特別なSDO_GEOMETRYメソッドを使用してGeoJSONデータを扱うことができます。

SpatialでのGeoJSONのサポートには次のものが含まれます。

  • SDO_GEOMETRYオブジェクトをGeoJSONオブジェクトに変換するSDO_UTIL.TO_GEOJSONファンクション。

  • GeoJSONオブジェクトをSDO_GEOMETRYオブジェクトに変換するSDO_UTIL.FROM_GEOJSONファンクション。

  • SDO_GEOMETRY型のGet_GeoJsonメソッド(メンバー・ファンクション)(説明と例については、「SDO_GEOMETRYのメソッド」を参照)。

例1-4 SpatialでのGeoJSONのサポート

この例では、SpatialでGeoJSONサポートを使用した操作をいくつか示します。例では、GeoJSON列とSDO_GEOMETRY列を持つ単純な表を作成し、サンプル・データを挿入して単純な問合せを実行します。空間索引を作成し、SDO_WITHIN_DISTANCE演算子を使用して問合せを実行します。

例では、次のJSON関連のOracle Databaseの機能を使用します(『Oracle Database JSON開発者ガイド』を参照)。

  • GeoJSONオブジェクトを反映したSDO_GEOMETRYオブジェクトを戻す、RETURNING SDO_GEOMETRYを指定したJSON_VALUE Oracle SQLファンクション

  • 列にJSONデータが含まれていることを確認する、CREATE TABLE文内のチェック制約のIS JSON Oracle SQL条件

例には、説明のコメントとSQL文の出力が含まれます。(出力は、簡単に読むことができるように、再フォーマットされています。)
