Common Pitfalls When Exporting MariaDB to JSON

A relational result is flat but JSON is nested - decide whether to emit an array of objects or wrap rows under a key.
JSON has no date type, so dates land as strings and the consumer has to parse them.
Very large integers lose precision in some JSON readers because they are parsed as doubles.
NULL and a missing key are different in JSON - pick one convention or downstream code will break.
The MySQL traps all apply: NULL versus empty string, plus binary columns that need base64.
Very wide tables can hit the server max_allowed_packet limit during export.
