format is as follows:
[{"City": "Beijing", "area": 16800, "Population": 1600 },{"City": "Shanghai", "area": 6400, "Population": 1800}]
If you know the data structure in advance, the preceding statement can be further simplified:
[["Beijing", 16800,1600],["Shanghai", 6400,1800]]
JSON is easy to learn and use. Therefore, in just a few years, it has replaced XML and become the most popular data exchange format on the Internet.

1) The data is separated by commas (",").
2) The map is represented by a colon (":").
3) a set (array) of side data is expressed in square brackets ("[]").
4) The Set of Mappings (objects) are represented by curly braces ("{}").
The above four rules are a
Arranges (rank ()) functions. These permutation functions provide the ability to define a set (using the PARTITION clause), and then arrange the elements in the collection according to some sort of order, and the following is an example of the Scott User's EMP table to illustrate how the rank over PARTITION is used.
