Hands-on Learning Event in Honolulu 1 : Introduction to Structured Query Language

Database skills are essential in whatever organization and in whatever position and it is crucial that you have this in your arsenal (Resume')
Databases, organized repositories of information, have become indispensable in today's world. In this introductory course you will learn about relational databases and the basics of Structured Query Language (SQL) including sorting; grouping result sets; using DDL, DML, DCL, and TCL. All SQL statements will initially be written for one table. Most practical, modern and relational databases will include a large number of tables and SQL queries have to access information from several tables. This course will introduce you to querying more than one table. With this skill you will be able to query two or more tables in a database.
This is a hands-on course which will take you from installing SQL Server 2016 to learning the ins and outs of SQL Server Management Studio and of course a full dose of SQL. The course covers most of the requirements to take Microsoft's certification (98-364), the Microsoft Technology Associate. During each meeting, you will be assessed for your knowledge, competency and proficiency in SQL.

SELECT query on OpenJSON using SQL Server 2016

OpenJSON converts an array of objects in a variable in JSON Format to a rowset
that can be queried with standard SQL Select statement.

Here is an example:

We are going to look at a JSON list of my first batch of students who took my course shown here. 

["wclass",
{"student":{"name":"Linda Jones","legacySkill":"Access, VB 5.0"}
},
{"student":{"name":"Adam Davidson","legacySkill":"Cobol, MainFrame"}
},
{"student":{"name":"Charles Boyer","legacySkill":"HTML, XML"}
}]

This is the result of running OpenJSON using the above:

Now you can run a SELECT query with a with clause on the rows returned by OpenJSON as shown here:

The first member "wclass" has nulls for the selected columns. It exists because it actually was in the original XML that got converted to JSON.
