TSql - Intermediate - 4

Embedding sub queries within standard SQL statements is a good way to isolate individual entries from an otherwise large table ofdata. When we say isolate in this sense, we mean a specific singular query based on a singular criteria. Consider the “users” tablebelow:

ID FIRSTNAME SURNAME DATEOFBIRTH SEX BIRTHLOCATIONID MIGRATED CURRENTLOCATIONID

1 Alan Person 02-01-1970 M 1 False 1

2 Jane Doe 10-05-1980 F 1 True 6

6 Thomas Peabody 08-21-2011 M Null True 1

7 Angie Agenew 05-16-2007 F 7 Null Null

Given the following request:Produce a query that will return the oldest user in the users table, this query should return the id, firstname, surname andbirthdate in separate columns. Which of the following queries will produce the requested result:

SELECT TOP 1 u1.ID, u1.FIRSTNAME, u1.SURNAME, u1.DATEOFBIRTH FROM Users ORDER BY DATEOFBIRTH

SELECT (MAX(Year) FROM Users) INTO u1.ID, u1.FIRSTNAME, u1.SURNAME, u1.DATEOFBIRTH FROM Users u1

SELECT ID, FIRSTNAME, SURNAME, DATEOFBIRTH FROM Users WHERE year(DATEOFBIRTH) = (SELECT

MIN(YEAR(DATEOFBIRTH)) FROM Users)

SELECT TOP 1u1.ID + u1.FIRSTNAME + u1.SURNAME + u1.DATEOFBIRTH AS [Oldest User] FROM Users u1 WHERE

year(DATEOFBIRTH) = Oldest(YEAR FROM Users AS u2) ORDER WITH DATEOFBIRTH

I don't know






Simple joins are a fact of life when building TSql queries. Most of the data you work with, will not just be in one single table, it willo en be split over several tables. As such, consider the table shema below:Users Table

Given the following requirements:Design a query, which will return all people listed in the database, this data set must contain the persons full name in asingle column, the year of their birth and the name of their birth location, no filtering shall be done on the dataset and all rowsshould be returned. Which of the following queries will satisfy this requirement and produce the requested data?

select u.FIRSTNAME + ’ ’ + u.SURNAME as [Full Name], year(u.DATEOFBIRTH) as [Year of Birth], l.NAME as [Place of Birth] from Users as u left outer join

Locations l on u.BIRTHLOCATIONID = l.ID

select u.FIRSTNAME + ’ ’ + u.SURNAME as [Full Name], year(u.DATEOFBIRTH) as [Year of Birth], l.NAME as [Place of Birth]

from Users as u right outer join Locations l on u.BIRTHLOCATIONID = l.ID

select FullName(u.FIRSTNAME, u.SURNAME), YearOfBirth(u.DATEOFBIRTH), PlaceName(l.NAME) from Users as u left outer

join Locations l on u.BIRTHLOCATIONID = l.ID

select FIRSTNAME + ’ ’ + SURNAME as [Full Name], year(DATEOFBIRTH) as [Year of Birth], NAME as [Place of Birth] from

Users left outer join Locations on BIRTHLOCATIONID = ID








Some mes you need to present data differently to how it’s stored in the database table, to do this you can actually makedecisions based on the data you have and show the output as something different, this can be achieved using a casestatement or a simple if/then statement. Taking the ‘sex’ column in our users table below, you’ve been asked to display thefull sex rather than just ‘M’ or ‘F’. This is to be displayed along with the full name in the order; surname first separated by acomma, and using only 2 columns; one for the name and one for the sex.



2 Jane Doe 10-05-1980 F 1 True 6






Which of the following queries will produce the required output:

I don't know

select surname + ‘, ’ + firstname as [Full Name],case sex when ‘M’ then ‘Male’ when ‘F’ then ‘Female’ end as sex from users

select surname + ‘, ’ + firstname as [Full Name],if sex = ‘M’ then ‘Male’ else if sex = ‘F’ then ‘Female’ as sex from users

select surname + comma + firstname , if case is sex = ‘M’ then return ‘Male’ if case is sex = ‘F’ then return ‘Female’ end as sex

from users

select fullname(surname, firstname) as [Full Name],case when sex in ‘M’ then sex = ‘Male’ when sex in ‘F’ then sex = ‘Female’

return sex from users

Stringing together chains of functions in TSql is one way to perform multiple transformations on your data output. In somecases you might need TSql to produce your final output text, when you have a requirement like this, you need to know whichfunction calls you need to produce, transform and convert the data types you need to produce your output. Consider the“users” table below:



2 Jane Doe 10-05-1980 F 1 True 6






Given the following specification:Create a query that will create one column of data called ‘Description’ for each row in the Users table, the format of each rowshould be the users full name in all capitals, followed by ‘Has been alive for X days since Day of month name Year’ whereday and year are the numerical equivalent of those date parts and month name is the full textual month name. Which of the following statements will produce this output:

SELECT upper(FIRSTNAME + ’ ’ + SURNAME) + ’ Has been alive for ’ + CAST(DATEDIFF(day, DATEOFBIRTH, CURRENT_TIMESTAMP) as varchar(10))

+ ’ days, since ’ + CAST(DATENAME(day, DATEOFBIRTH) as varchar) + ’ of ’ + CAST(DATENAME(month, DATEOFBIRTH) as varchar) + ’

’ + CAST(year(DATEOFBIRTH) as varchar) as [Description] FROM Users

SELECT upper(FIRSTNAME + ’ ’ + SURNAME) + ’ Has been alive for ’ + CAST(DATEDIFF(day, DATEOFBIRTH,

CURRENT_TIMESTAMP) as varchar(10)) + ’ days, since ’ + CAST(DATENAME(day, DATEOFBIRTH) as varchar)

+ ’ of ’ + CAST(DATENAME(month, DATEOFBIRTH) as varchar) + ’ ’ + CAST(year(DATEOFBIRTH) as varchar)

as [Description] FROM Users

SELECT FIRSTNAME.ToUpper() + ’ ’ + SURNAME.ToUpper() + ’ Has been alive for ’ + CONVERTTO(DATEDIFF(day,

DATEOFBIRTH, CURRENT_TIMESTAMP) as varchar) + ’ days, since ’ + CONVERTTO(DATENAME(day, DATEOFBIRTH) as

varchar) + ’ of ’ + CONVERTTO(DATENAME(month, DATEOFBIRTH) as varchar) + ’ ’ + CONVERTTO(year(DATEOFBIRTH)

as varchar) as [Description] FROM Users

SELECT UPPERCASE((FIRSTNAME + ’ ’ + SURNAME) + ’ Has been alive for ’ + CAST(DATEDIFF(day, DATEOFBIRTH,

CURRENT_TIMESTAMP) as varchar(10)) + ’ days, since ’ + CAST(DATENAME(day, DATEOFBIRTH) as varchar)

+ ’ of ’ + CAST(DATENAME(month, DATEOFBIRTH) as varchar) + ’ ’ + CAST(year(DATEOFBIRTH) as varchar))

as [Description] FROM Users

Reverse Words - C# - Basic

Write a method to return the reverse order for a list of space separated words.Example: “A sample sentence is required” would return “required is sentence sample A”

using System;using System.Collections.Generic;using System.IO;using System.Text;

public class Solution{ public string ReverseWords(string input) { string[] words = input.Split(' '); StringBuilder result = new StringBuilder(); for (int i = words.Length -1 ; i > -1; i--) { result.Append(words[i]); if(i > 0) { result.Append(" "); } } return result.ToString(); }}
