SnowConvert AI - Oracle - Spatial Types

Description

Oracle Spatial and Graph is designed to make spatial data management easier and more natural to users of location-enabled applications, geographic information system (GIS) applications, and geoimaging applications. (Oracle SQL Language Reference Spatial Types)

SDO_GEOMETRY

Note

Some parts in the output code are omitted for clarity reasons.

Description

The geometric description of a spatial object is stored in a single row, in a single column of object type SDO_GEOMETRY in a user-defined table. Any table that has a column of type SDO_GEOMETRY must have another column, or set of columns, that defines a unique primary key for that table. (Oracle SQL Language Reference SDO_GEOMETRY Data Type)

Definition of SDO_GEOMETRY object:

CREATE TYPE SDO_GEOMETRY AS OBJECT
  (sgo_gtype        NUMBER,
   sdo_srid         NUMBER,
   sdo_point        SDO_POINT_TYPE,
   sdo_elem_info    SDO_ELEM_INFO_ARRAY,
   sdo_ordinates    SDO_ORDINATE_ARRAY);
/

The SDO_GEOMETRY object is not supported in Snowflake. A workaround for this data type is to use Snowflake GEOGRAPHY, however that transformation is currently not supported by SnowConvert.

Sample Source Patterns

SDO_GEOMETRY in Create Table

Oracle

CREATE TABLE geometry_table(
    geometry_column SDO_GEOMETRY
);
Snowflake

CREATE OR REPLACE TABLE geometry_table (
        geometry_column GEOMETRY
    )
    COMMENT = '{"origin":"sf_sc","name":"snowconvert","version":{"major":1, "minor":0},{"attributes":{"component":"oracle"}}'
    ;

Inserting data in SDO_GEOMETRY Table

Oracle

INSERT INTO geometry_table VALUES (
	SDO_GEOMETRY('POINT(-79 37)')
);

INSERT INTO geometry_table VALUES (
    SDO_GEOMETRY('LINESTRING(1 3, 1 5, 2 7)')
);

INSERT INTO geometry_table VALUES (
    MDSYS.SDO_GEOMETRY(
		2001,
		8307,
		MDSYS.SDO_POINT_TYPE (
			-86.13631,
			40.485424,
			NULL),
		NULL,
		NULL
	)
);

INSERT  INTO geometry_table VALUES (
SDO_GEOMETRY(
    2003,
    12,
    SDO_POINT_TYPE(12, 14, -5),
    SDO_ELEM_INFO_ARRAY(1,1003,3),
    SDO_ORDINATE_ARRAY(1,1, 5,7)
  )
);

INSERT INTO geometry_table VALUES (
NULL);
Snowflake

Migration using the GEOGRAPHY data type

Oracle

CREATE TABLE geometry_table(
    geometry_column SDO_GEOMETRY
);

INSERT INTO geometry_table VALUES (
	SDO_GEOMETRY('POINT(-79 37)')
);

INSERT INTO geometry_table VALUES (
    SDO_GEOMETRY('LINESTRING(1 3, 1 5, 2 7)')
);
