解析數組中的Json對象到關係對象和字段中

-2

嗨我需要解析操作數組下的json對象到關係字段和對象中，但這裏的技巧是我粘貼的示例有七個對象在operationsList數組下，我的代碼能要分別解析每個json對象，但是需要使用能夠自動選擇每個json對象的函數。解析數組中的Json對象到關係對象和字段中

我需要的答案在pgAdmin的$執行Postgres的9.6

注：我使用所有的功能

下面的代碼

編輯您的問題：1.標記一種語言2.選擇所有代碼並點擊Ctrl-K。 –

你的意思是什麼*關係字段和對象*？你已經有一個模式？（['json [b] _populate_recordset（）']（https://www.postgresql.org/docs/current/static/functions-json.html）） - 或者你想爲你的JSON輸入創建一個模式-THE飛？（似乎很冒險） – pozs

我已經有關係表和字段的架構列名稱是「文本」「工作中心」「controlKey」「細節」我需要做的就是解析json對象的列值數組插入到這些表列中。 –

ArrayList<operationsList> objOperationsList=new ArrayList<>(); 

class operationsList 

{ 

String order; 

String text; 

String workCenter; 

String controlKey; 

Details objDetails; 

} 

class Details 

{ 

    String longText; 

ArrayList<MICS> objMICS=new ArrayList<>(); 

    ArrayList<Dependencies> objDependencies=new ArrayList<>(); 

    ArrayList<Documents> objDocuments=new ArrayList<>(); 

} 

class MICS {} 

class Dependencies {} 

class Documents {}

這是不正確的答案我認爲在數據庫中執行pl/pgsql –

的JSON列，而不是JSONB我曾在JSON列這整個JSON代碼（上面粘貼），我有其中列順序，工作中心，CONTROLKEY，表中的文本，所以我需要選擇手術檯上從JSON對象的值，並將這些值代入列，以便我能夠做到這一點使用此查詢

INSERT INTO public.operation(
order_1, text, workcenter_number, control_key, long_text) 
    (select

router_payload :: JSON＃>「{operationsList，5}」 - >>「秩序」， router_payload :: json＃>'{operationsList，5}' - >>'text'，

router_payload :: json＃>'{operationsList，5}' - >>'workCenter'，

router_payload :: json＃>'{operationsList，5}' - >>'controlKey'， router_payload＃>' {operationsList，5}' - >'details' - >>'longText'，

from public.router_data ）;

但是我的問題如果你在查詢中看到我指定{operation，5} 我不想給我，我試圖使它成爲循環，或者當我執行時需要選擇所有操作查詢

如果您進一步指定您的問題，請編輯問題本身，而不是張貼它作爲答案。 – pozs

然後請發佈您的完整架構。沒有它我們可以猜測。 – pozs
