 Last but not least, by enabling type casting, native SQL data type checks are also performed ensuring 100% fidelity between stored binary values in the encoded JSON and SQL data types. As a result, we can store not just the standard JSON data types but also the SQL data types inside the encoded binary JSON such as `NUMBER`, `DATE`, `TIMESTAMP`, `TIMESTAMP WITH TIME ZONE`, `INTERVAL`, `RAW`, `VECTOR`, etc.
