SQL Server provides with three views to display the relations in an SQL Server database. These views are called (1) (2) and (3) - 3 points and are the SQL Server JOIN types. - 3 points Lets suppose we would like to display all the tuples with "valid email addresses" of a Personnel relation. "valid email address" is defined as: (a) it should include one '@', and one '.' characters. (b) @, should be located before '.'. (c) there should be at least one character between @ and the ' character. (d) there should be at least 3 characters after the ' character. (e) Before @, there should be at least 4 characters. Assuming that the attribute name is EmailAddress, write down the WHERE clause of the required SELECT statement: WHERE
