解説

By default the connector will only qualify a column name as much as is necessary to make it unique. For example, in this document the connector will produce the columns id (referring to the company id) and employee.id.

{
  "company": [
    {
      "id": "Smith Holdings", 
      "employee": [
        {"id": "George Smith"},
        {"id": "Mike Johnson"}
      ]
    }
  ]
}

When this option is set to Parent, the connector uses a similar procedure to the one above. However, the connector will always qualify columns by one level so that their table name is included, even if the column name is unique. For example, the above document would generate the columns company.id and employee.id because both are unique when including their parent.

When this option is set to Full, the connector will qualify all column names with their full XPath. This generates longer column names but ensures that it is clear where each column name comes from within the document. For the example above, the connector would generate the columns json.company.id and json.company.employee.id.
