thanks @pranavj it was really helpful in my project
Same here. How do I rename or delete only one column in a collection. Exporting the data to csv and recreating the collection is not efficient way.
Hello Manuel,
Kinvey uses MongoDB which is a NoSQL database. Unlike relational databases, where data is organized into tables which are defined by a schema (columns and datatypes each column can hold), MongoDB is organized into collections which contain documents in which data organized into key value pairs. Therefore there are no actual columns at all in the data. Each item in a collection consists of field-value pairs ({Field-Name: Field-Value}).
When you want to rename the field name you need to update all items in the database ("Field-Name" with "New-Field-Name").
Therefore the process to follow is:
- Export data to csv/json
- Clear collection data
- Update all items Field-Names
- Import updated collection data from csv/json
With the above process, the _kmd (Kinvey Metadata) which holds the item creation date and last modification date would stay the same.
