Concept explainers
Display values from table:
The contents from the table can be viewed by using “SELECT” statement which comes under Data Manipulation Language (DML).
The Syntax to view the contents using asterisk (*) is as follows:
SELECT * FROM table_Name;
Selective columns can also be retrieved by replacing all the column(s) names in place of the asterisk symbol.
ORDER BY Clause:
SQL contains “GROUP BY” clause in order to sort rows. The values get sorted in ascending as well as descending order.
The keyword used to sort values in ascending order is “ASC” and for descending order is “DESC”. By default, it sorts values by ascending order.
Syntax:
SELECT column_Name1, column_Name2 FROM table_Name ORDER BY column_Name2 ASC, column_Name1 DESC;

- USE NORTHWIND DATABASE Write a SELECT statement using the CASE function. The statement returns two columns basedon how many orders the customer has in the database.

- **In SQL** Write a SELECT statement that returns these columns: InstructorDept The DepartmentName column from the Departments table for a related instructor LastName The LastName column from the Instructors table FirstName The FirstName column from the Instructors table CourseDescription The CourseDescription column from the Courses table CourseDept The DepartmentName column from the Departments table for a related instructor Return one row for each course that’s in a different department than the department of the instructor assigned to teach that course. (Hint: You will need to join the Departments table to both the Instructors table and the Courses table, which will require you to use table aliases to distinguish the two tables.)arrow_forwardWrite the SQL code that will produce the same information that was shown in Problem 2, but sorted by the employee’s last name.
