Oracle APEX中的POST请求（数组）

Question

我在json中有一个数组，我想在oracle方法中写它。但是我在某个地方找不到我的错误。我尝试将其全部编写成一个循环，但代码可以编译但不编写。我要做的第一件事是使用循环查找第一个对象。然后，我在对象中间使用另一个循环来记录其中的数据！

    v_clob := iot_general.blob_to_clob(p_blob); 
    apex_json.parse(tv, v_clob); 
    sCount := APEX_JSON.get_count(p_path => 'GroupSensor' , p_values => tv); 
    IF sCount > 0 THEN 
      FOR i in 1 .. sCount LOOP 
      v_id := apex_json.get_varchar2(p_path => 'GroupSensor.SerialNumber['|| i ||']', p_values => tv);  
                  cCount := APEX_JSON.get_count(p_path => 'GroupSensor.GroupBob['|| i ||']' , p_values => tv); 
                  IF cCount > 0 THEN 
                              FOR q in 1 .. cCount LOOP 
                              q_temp   := apex_json.get_varchar2(p_path => 'GroupSensor.GroupBob['|| i ||']['|| q ||']', p_values => tv);  
                                INSERT INTO SILO_SENSOR( NAME,  DEVICES_ID)  
                                VALUES (q_temp,v_id  ); 
                                commit; 
                                END LOOP;    
                 END IF; 
      END LOOP; 
    END IF; 

这是我的json

 {
  "GroupSensor": [
    {
      "silos": 1,
      "GroupBob": [
        "SENSOR0001",
        "SENSOR0002",
        "SENSOR0003",
        "SENSOR0004",
        "SENSOR0005",
        "SENSOR0006",
        "SENSOR0007",
        "SENSOR0008",
        "SENSOR0009",
        "SENSOR0010"
      ],
      "SerialNumber": "1701"
    },
    {
      "silos": 1,
      "GroupBob": [
        "SENSOR0011",
        "SENSOR0012",
        "SENSOR0013",
        "SENSOR0014",
        "SENSOR0015",
        "SENSOR0016",
        "SENSOR0017",
        "SENSOR0018",
        "SENSOR0019"
      ],
      "SerialNumber": "1702"
    },
    {
      "silos": 1,
      "GroupBob": [
        "SENSOR0020",
        "SENSOR0021",
        "SENSOR0022",
        "SENSOR0023",
        "SENSOR0024",
        "SENSOR0025",
        "SENSOR0026",
        "SENSOR0027",
        "SENSOR0028"
      ],
      "SerialNumber": "1703"
    }
]

}

我想将数据写入SILO_SENSOR表，就这样

NAME            DEVICES_ID
SENSOR0001      1701
SENSOR0002      1701
SENSOR0003      1701
SENSOR0004      1701
SENSOR0005      1701
SENSOR0006      1701
SENSOR0007      1701
SENSOR0008      1701
SENSOR0009      1701
SENSOR0010      1701

您没有正确访问数组：

尝试以下操作：

BEGIN
    apex_json.parse(tv, v_clob);
    scount := apex_json.get_count(p_path => 'GroupSensor', p_values => tv);
    IF scount > 0 THEN
        FOR i IN 1..scount LOOP
            v_id := apex_json.get_varchar2('GroupSensor[%d].SerialNumber', i);

            ccount := apex_json.get_count(p_path => 'GroupSensor[%d].GroupBob', p0 => i, p_values => tv);

            IF ccount > 0 THEN
                FOR q IN 1..ccount LOOP
                    q_temp := apex_json.get_varchar2('GroupSensor[%d].GroupBob[%d]', i, q);
                    INSERT INTO silo_sensor (
                        name,
                        devices_id
                    ) VALUES (
                        q_temp,
                        v_id
                    );

                    COMMIT;
                END LOOP;
            END IF;
        END LOOP;
    END IF;
END;

我做了

    v_clob := iot_general.blob_to_clob(p_blob); 
apex_json.parse(tv, v_clob); 
sCount := APEX_JSON.get_count(p_path => 'GroupSensor' , p_values => tv); 
IF sCount > 0 THEN 
          FOR i in 1 .. sCount LOOP 
          v_id := apex_json.get_varchar2(p_path => 'GroupSensor['|| i ||'].SerialNumber', p_values => tv);  
          cCount := APEX_JSON.get_count(p_path => 'GroupSensor['|| i ||'].GroupBob' , p_values => tv); 
          IF cCount > 0 THEN 
                          FOR q in 1 .. cCount LOOP 
                                  q_temp   := apex_json.get_varchar2(p_path => 'GroupSensor['|| i ||'].GroupBob['|| q ||']', p_values => tv);  
                                  INSERT INTO SILO_SENSOR( NAME,  DEVICES_ID)  
                                  VALUES (q_temp,v_id  ); 
                                 commit; 
                         END LOOP;    
             END IF; 
  END LOOP; 
END IF;
