Engineering Computer Science Oracle 12c: SQL

To write a query to display the list of all books customers which are purchased by Jake Lucas. Required SQL query: SELECT DISTINCT c.firstname||’’||c.lastname "NAME", b.title FROM customers c INNER JOIN orders o ON c.customer# = 0.customer# INNER JOIN orderitems oi ON oi.order# = o.order# LEFT JOIN books b ON b.ISBN = oi.ISBN WHERE (c.firstname||’’||c.lastname) = 'JAKE LUCAS’; Explanation: SELECT keyword will allow the user to retrieve the required values. By providing the table name, FROM can be used to search the database and return the desired data. WHERE is used to specify a condition based on which the data is to be retrieved. AND is used to specify that both conditions must be satisfied. ON clause is used in joining the columns who are having different names. The JOIN Clause is a special keyword in SQL (structured Query Language), which is used to combine the rows from two or more tables in the database. INNER JOIN selects records that have the same(matching) values which are present in both tables. LEFT JOIN selects all records from the table listed on the left side of the join, even when no match is found with the table (another one) in the join operation. In the above SQL query, it selects the Customer name and the title. The distinct keyword is used to avoid duplicate records. Perform the search using the customer name instead of the customer#. Sample output: CUSTOMER NAME TITLE JAKE LUCAS PAINLESS CHILD-REARING JAKE LUCAS HOW TO MANAGE THE MANAGER
