Select rows into columns and show a flag in the column - sql

Question

Trying to get an output like the below:
| UserFullName | JAVA | DOTNET | C | HTML5 |
|--------------|--------|--------|--------|--------|
| Anne San | | | | |
| John Khruf | 1 | 1 | | 1 |
| Mary Jane | 1 | | | 1 |
| George Mich | | | | |
This shows the roles of a person. A person could have 0 or N roles. When a person has a role, I am showing a flag, like '1'.
Actually I have 2 blocks of code:
Block #1: The tables and a simple output which generates more than 1 rows per person.

MS SQL Server 2008 Schema Setup:
CREATE TABLE AvailableRoles
(
id int identity primary key,
CodeID varchar(5),
Description varchar(500),
);
INSERT INTO AvailableRoles
(CodeID, Description)
VALUES
('1', 'JAVA'),
('2', 'DOTNET'),
('3', 'C'),
('4', 'HTML5');
CREATE TABLE PersonalRoles
(
id int identity primary key,
UserID varchar(100),
RoleID varchar(5),
);
INSERT INTO PersonalRoles
(UserID, RoleID)
VALUES
('John.Khruf', '1'),
('John.Khruf', '2'),
('Mary.Jane', '1'),
('Mary.Jane', '4'),
('John.Khruf', '4');
CREATE TABLE Users
(
UserID varchar(20),
EmployeeType varchar(1),
EmployeeStatus varchar(1),
UserFullName varchar(500),
);
INSERT INTO Users
(UserID, EmployeeType, EmployeeStatus, UserFullName)
VALUES
('John.Khruf', 'E', 'A', 'John Khruf'),
('Mary.Jane', 'E', 'A', 'Mary Jane'),
('Anne.San', 'E', 'A', 'Anne San'),
('George.Mich', 'T', 'A', 'George Mich');
Query 1:
SELECT
A.UserFullName,
B.RoleID
FROM
Users A
LEFT JOIN PersonalRoles B ON B.UserID = A.UserID
WHERE
A.EmployeeStatus = 'A'
ORDER BY
A.EmployeeType ASC,
A.UserFullName ASC
Results:
| UserFullName | RoleID |
|--------------|--------|
| Anne San | (null) |
| John Khruf | 1 |
| John Khruf | 2 |
| John Khruf | 4 |
| Mary Jane | 1 |
| Mary Jane | 4 |
| George Mich | (null) |
Block #2: An attempt to convert the rows into columns to be used in the final result

INSERT INTO AvailableRoles

Results:
| Java | DOTNET | C | HTML5 |
|--------|--------|-------|--------|
| 1 | 2 | 3 | 4 |
Any help in mixing both blocks to show the top output will be welcome. Thanks.

Answer 1

Another option without PIVOT operator is:
select u.UserFullName,
max(case when a.CodeID='1' then '1' else '' end) JAVA,
max(case when a.CodeID='2' then '1' else '' end) DOTNET,
max(case when a.CodeID='3' then '1' else '' end) C,
max(case when a.CodeID='4' then '1' else '' end) HTML5
from
Users u
LEFT JOIN PersonalRoles p on (u.UserID = p.UserID)
LEFT JOIN AvailableRoles a on (p.RoleID = a.CodeID)
group by u.UserFullName
order by u.UserFullName

Answer 2

You can try this.
SELECT *
FROM
(
select u.userfullname,
case when p.roleid is not null then 1 end as roleid,
a.description
from users u
left join personalroles p
on p.userid = u.userid
left join availableroles a
on a.codeid = p.roleid
) d
PIVOT
(
MAX(roleID)
FOR Description IN (Java, DOTNET, C, HTML5)
) piv
