ABENDDIC_GEO_DATA - DDIC GEO DATA

- Geodata Types

The geodata type GEOM_EWKB is a built-in data type in ABAP Dictionary that describes the geometric position in a given coordinate reference system.

It represents fields in the database that contain geometric data in the EWKB (Extended Well-Known Binary) format. This type is currently only supported on SAP HANA databases and references the database type ST_GEOMETRY.

The internal representation of the geodata type GEOM_EWKB is a BLOB (Binary Large Object) and the same rules and restrictions largely apply as to the type RAWSTRING. The type GEOM_EWKB is mapped to the ABAP type xstring.

At ABAP level, there is no semantic representation for geometric data. ABAP only allows geometric data to be passed between the application and the SAP HANA database. The SAP HANA database functions for geometric data types can be accessed using AMDP.

If the data type GEOM_EWKB is used for a structure component or a table field of a DDIC database table, the type must be assigned a spatial reference system. This system cannot be changed once activated. The system has the ID 0 by default.

Notes

• Columns of the data type GEOM_EWKB are not supported as BLOBs in streaming and locators in. To use columns of the data type GEOM_EWKB in streaming and locators, they have to be converted to JSON format first. This can be done with the conversion function AS_GEO_JSON.

• NOT NULL cannot be set for a column of the type GEOM_EWKB.
