The @JsonProperty annotation can be used to indicate the property name in JSON. This annotation can be used for a constructor or factory method. The @JsonCreator annotation is useful in situations where the @JsonSetter annotation cannot be used. For instance, immutable objects do not have any setter methods, so they need their initial values injected into the constructor.@JsonProperty - ConstructorExampleimport com.fasterxml.jackson.annotation.*; import java.io.IOException; import com.fasterxml.jackson.databind.*; public class JsonCreatorTest1 { public static void main(String[] args) throws IOException { ObjectMapper om = new ObjectMapper(); String jsonString = "{\"id\":\"101\", \"fullname\":\"Ravi Chandra\", \"location\":\"Pune\"}"; System.out.println("JSON: " + jsonString); ...

In SAP HANA, you don’t have a concept of creating multiple databases in one container. To create a separate container for your database objects, you can create the schema in HANA db.To create a schema, you can use below SQL query −CREATE SCHEMA schema nameYou can also define as owner name while defining a schema.CREATE SCHEMA [OWNED BY ]If it is not defined, the system takes the current user as the owner of the schema.
In SAP HANA, geospatial data types are not defined as such and you need to use scalar values like a.ST_X().You can create a table like this −CREATE COLUMN TABLE MYSCHEMA.SpatialShapes_GEOMETRIES ( ShapeID integer, SHAPE1 ST_Point, SHAPE2 ST_GEOMETRY );SAP provides a complete guide to handle Geospatial data in applications.
