Sample Solution:
-- Concatenating the first name and last name with a space between them, and then concatenating the email address with a line break character
SELECT concat(p.FirstName,' ', p.LastName) || ' '|| chr(10)|| pe.EmailAddress
-- From the Person schema's Person table, aliasing it as 'p'
FROM Person.Person p
-- Performing an inner join with the EmailAddress table based on BusinessEntityID
-- Only including rows where BusinessEntityID matches '1' in both tables
INNER JOIN Person.EmailAddress pe ON p.BusinessEntityID = pe.BusinessEntityID
AND p.BusinessEntityID = 1;
Explanation:
- The SQL query concatenates the first name, last name, and email address for a specific person, adding a line break between the full name and the email address.
- It retrieves data from the Person table within the Person schema.
- The INNER JOIN clause is used to combine rows from the Person table (aliased as 'p') with matching rows from the EmailAddress table based on the common column BusinessEntityID.
- The ON clause specifies the condition for the join: p.BusinessEntityID = pe.BusinessEntityID ensures that rows are joined based on the matching BusinessEntityID, and p.BusinessEntityID = 1 restricts the join to only include rows where BusinessEntityID is equal to '1' in both tables.
- The concat() function concatenates the first name and last name with a space between them, and then concatenates the email address with a line break character (chr(10)).
