Package oracle.sql.json

Class OracleJsonDatum

java.lang.Object

oracle.sql.Datum

oracle.sql.json.OracleJsonDatum

All Implemented Interfaces:

Serializable

public class OracleJsonDatum
extends Datum

Represents a JSON type value and holds Oracle binary JSON.

Instances of OracleJsonDatum can be used with JDBC methods such as OracleResultSet.getOracleObject(int) and OraclePreparedStatement.setOracleObject(int, Datum) that accept and return Datum. The primary use case for OracleJsonDatum is to obtain raw Oracle binary JSON directly from a query result. For example:

    ResultSet rs = stmt.executeQuery("select jsonCol from mytbl");
    rs.next();
    OracleJsonDatum datum = rs.getObject(1, OracleJsonDatum.class);
    byte[] binaryJson = datum.shareBytes();
    ...
