SQL

Consider the database table structure shown in the figure. (a) Write a SELECT statement (compatible with an Oracle RDBMS) that returns three columns from the vendors table: vendor_name, vendor_ contact last_name, and vendor_contact_first_name. Write the query so that each database column is aliased in the result set as a similar column name that uses spaces instead of underscores. (b) Then write two result dataset rows of sample data that might be retrieved by the query. What is actually retrieved depends on what is in the table. The data you write does not have to match any data that is actually in our sample tables.
