Oracle Date Format: N1QL and Support for Date-Time Functions

The comparison between Couchbase and Oracle date-time formats highlights the differences in handling dates and times in relational and NoSQL databases. Oracle offers various date-time data types like DATE and TIMESTAMP, which can be formatted using parameters such as NLS_DATE_FORMAT, providing flexibility in how dates are represented and manipulated. Couchbase, on the other hand, uses ISO 8601 formats where dates and times are stored as strings, with functions available for manipulation, emphasizing ease and consistency over flexibility. Oracle supports up to 9-digit precision for fractional seconds, whereas Couchbase limits to 3 digits. Both systems handle time zone considerations differently; Oracle uses specific data types for time zones, while Couchbase represents time zones as UTC offsets. N1QL in Couchbase supports additional date components like MILLENNIUM and QUARTER, which are not available in Oracle. The article illustrates how Couchbase offers a simple and flexible approach to date handling, albeit with more restrictions on format customization compared to Oracle's parameterized flexibility.
