解析 Json 并插入到 oracle table

Question

我有一个 json 变量，我想将所有数据插入到我的 table。

json 响应是这样的：

    {
    "data": [{
        "pid": "10",
        "name": "sss",
        "consumer_price": "100",
        "discount": "10",
        "sale_price": "90"
    }, {
        "pid": "11",
        "name": "fff",
        "consumer_price": "100",
        "discount": "10",
        "sale_price": "90"
    }]
 }

我尝试使用 JSON_TABLE 将值插入我的 table

INSERT INTO tbl_product_temp (pid, name, consumer_price,discount,sale_price)

    SELECT key1, key2 , key3,key4,key5
      FROM JSON_TABLE (' 

       {
    "data": [{
        "pid": "10",
        "name": "sss",
        "consumer_price": "100",
        "discount": "10",
        "sale_price": "90"
    }, {
        "pid": "11",
        "name": "fff",
        "consumer_price": "100",
        "discount": "10",
        "sale_price": "90"
    }]

 }
',
                       '$.data'
                       COLUMNS 
                       key1 VARCHAR2 PATH '$.pid',
                       key2 VARCHAR2 PATH '$.name',
                       key3 VARCHAR2 PATH '$.consumer_price',
                       key4 VARCHAR2 PATH '$.discount',
                       key5 VARCHAR2 PATH '$.sale_price'
                       );

但它不起作用。实际上它适用于一组数据但对于更多它仍然不起作用请帮助我。

例如，

$.data 选择数组，但数组没有 .pid 键。 $.data[*]选择数组中的所有项，这就是你想要的。

SELECT key1, key2 , key3,key4,key5
      FROM JSON_TABLE (' 

       {
    "data": [{
        "pid": "10",
        "name": "sss",
        "consumer_price": "100",
        "discount": "10",
        "sale_price": "90"
    }, {
        "pid": "11",
        "name": "fff",
        "consumer_price": "100",
        "discount": "10",
        "sale_price": "90"
    }]

 }
',
                       '$.data[*]'
                       COLUMNS 
                       key1 VARCHAR2 PATH '$.pid',
                       key2 VARCHAR2 PATH '$.name',
                       key3 VARCHAR2 PATH '$.consumer_price',
                       key4 VARCHAR2 PATH '$.discount',
                       key5 VARCHAR2 PATH '$.sale_price'
                       );
