Data exported to XML
After SQL Server 2005, a FOR XML clause is provided to natively support XML in a relational database. This command enables you to convert a two-dimensional relational result set to XML, which can be saved as XML by using bcp.
For example, the following data:
We can export this to an XML file by using the following bcp command (note that you cannot have a carriage return) and

I saved a piece of JOSN code in a field in the data inventory, but the double quotation marks were escaped after the code was saved.
Like This
[{ Quot; id quot;: quot; 9 quot;, quot; model quot;: quot; A2 quot;, quot; quantity quot;: 1}]
It is also displayed in html without quotation marks.
How can I convert it into json code.

First of all, I think this example is very simple. As an android engineer, it is necessary to understand or develop the server background, write some interfaces, and so on, because the technology changes very quickly, but they all have some commonalities, in the process of constantly learning the language, discover things that do not change, to improve yourself. Recently, I think PHP is quite simple. I will share it with you next time.
