FlattenObjects
Set FlattenObjects to true to flatten object properties into columns of their own. Otherwise, objects nested in arrays are returned as strings of JSON.
Syntax
property FlattenObjects: Boolean;
Data Type
Boolean
Default Value
false
Remarks
Set FlattenObjects to true to flatten object properties into columns of their own. Otherwise, objects nested in arrays are returned as strings of JSON. The property name is concatenated onto the object name with an underscore to generate the column name.
For example, you can flatten the nested objects below at connection time:
[ { "grade": "A", "score": 2 }, { "grade": "A", "score": 6 }, { "grade": "A", "score": 10 }, { "grade": "A", "score": 9 }, { "grade": "B", "score": 14 } ]When FlattenObjects is set to true and FlattenArrays is set to 1, the preceding array is flattened into the following table:
Column Name | Column Value |
grades_0_grade | A |
grades_0_score | 2 |
