Handsontable JsonアレイをOracleテーブルに挿入する方法（バルク）

Question

var hot = new Handsontable(container, {} 
JSON.stringify({data: hot.getData()}) 

JSON: { data: [ 
     "col_1" // These are the table columns 
     "col_2"  
    ], 
    [ 
     "test2",// there are values 
     "201702"  
    ], 
    [ 
     "test2",// there are values 
     "201702" 
    ] 
} 

ここでは、列は常に動的です.iは、挿入クエリを適切に作成する必要があります。いくつかの手助けのデータをテーブルに挿入する方法を教えてください。

Answer 1

あなたJSONはここでその代替だ、私はあなたが配列の配列を持っているためのものと仮定した場合、このような何かがあなた

    2 ID NUMBER, 
    3 JSON_DOC CLOB CHECK (JSON_DOC IS JSON) 
    4 ) 
    5/

Table created.
