Имеется часть JSON файла, который хранится в Azure Blob Storage и из которого необходимо экспортировать данные в Azure SQL DB при помощи TSQL скрипта:
"accelerationPedalPositionClass": [
{
"from": 0.0,
"to": 20.0,
"seconds": 9516823
},
{
"from": 20.0,
"to": 40.0,
"seconds": 2508318
},
{
"from": 40.0,
"to": 60.0,
"seconds": 1154166
},
{
"from": 60.0,
"to": 80.0,
"seconds": 524101
},
{
"from": 80.0,
"to": 100.0,
"seconds": 572205
}
],
"accelerationClass": [
{
"to": -1.1,
"seconds": 176031,
"meters": 1716900,
"milliLitres": 468620
},
{
"from": -1.1,
"to": -0.9,
"seconds": 45066,
"meters": 458630,
"milliLitres": 143940
Основная проблема в повторяющихся в массивах параметрах from, to, seconds и тд. Ума не приложу, как извернуться, чтобы распарсить эту часть в табличную форму. Посоветуйте, пожалуйста. Желательно что-нибудь кроме "иди и учи мат. часть" :)
Мой скрипт:
