.]]] Note that there is a very important difference in our next operation on the Numarray array and the Python list. When you select the level of an array--we'll see that the layered approach in multidimensional arrays is very flexible and powerful--you get not a copy but a "view." There are several ways to point to the same data. Let's look at it specifically. Let's say we have a ventilation unit in our room that will reduce the temperature of the ground by four degrees:listing 11. Chan

Implementation of SQL Server native data from XML to generate JSON data instance code, xmljson Example code for generating JSON data from XML with SQL Server native data SQL Server is a relational database, and the query results are usually datasets. However, in some special situations, we need XML data. In the past few years, JSON has been used as a common data interchange format for webapis, how does the database generate JSON data? Today I wrote a DEMO. 1. Create tables and test data SET NOCO
