Get output column for each Key - sql

Question

I have a database with roughly this fields:
SELECT [UserId]
,[MissionId]
,[LevelId]
,[Key]
,[BooleanAnswer]
,[CreationDateTimeUtc]
,[QuestionId]
FROM [Bakman].[dbo].[LevelEntries]
WHERE LevelId = 2 AND QuestionId = 1 OR QuestionId = 2 OR QuestionId = 3 OR QuestionId = 4 OR QuestionId = 5 OR QuestionId = 6
Now I get this kind of output:
UserId MissionId LevelId Key BooleanAnswer CreationDateTimeUtc QuestionId
0 1 2 1 1 2017-10-07 11:39:26.350 1
0 1 2 2 1 2017-10-07 11:39:26.350 1
0 1 2 3 0 2017-10-07 11:39:26.350 1
0 1 2 4 1 2017-10-07 11:39:26.350 1
0 1 2 5 0 2017-10-07 11:39:26.350 1
0 1 2 6 1 2017-10-07 11:39:26.350 1
But now I want to get a column for each QuestionId (which are equal to the [key]).
Like this :
UserId MissionId LevelId Key1 Key2 Key3 Key4 Key5 Key6 CreationDateTimeUtc QuestionId
1 2 1 0 1 1 0 1 1 1 2017-10-07 11:39:26.350 1
Where Key[key] has the boolean awnser and the key belonging to that element.
Good to know is that the Userid + MissionId + LevelId + Key are the Composite key for this table.
EDIT:
Trying both given answers I now get something like this
UserId MissionId LevelId Key1 Key2 Key3 Key4 Key5 Key6
1 1 2 1 NULL NULL NULL NULL NULL
1 1 2 NULL 1 NULL NULL NULL NULL
1 1 2 NULL NULL 0 NULL NULL NULL
1 1 2 NULL NULL NULL 1 NULL NULL
1 1 2 NULL NULL NULL NULL 1 NULL
1 1 2 NULL NULL NULL NULL NULL 1
Now I want to combine those so I get the level result of the user.

Answer 1

Try the following query
SELECT
UserId,
MissionId,
LevelId,
MAX(CASE WHEN [Key]=1 THEN BooleanAnswer END) Key1,
MAX(CASE WHEN [Key]=2 THEN BooleanAnswer END) Key2,
MAX(CASE WHEN [Key]=3 THEN BooleanAnswer END) Key3,
MAX(CASE WHEN [Key]=4 THEN BooleanAnswer END) Key4,
MAX(CASE WHEN [Key]=5 THEN BooleanAnswer END) Key5,
MAX(CASE WHEN [Key]=6 THEN BooleanAnswer END) Key6,
CreationDateTimeUtc,
QuestionId
FROM LevelEntries
WHERE LevelId=2
AND QuestionId IN(1,2,3,4,5,6)
GROUP BY UserId,MissionId,LevelId,CreationDateTimeUtc,QuestionId
The second variant
SELECT
UserId,
MissionId,
LevelId,
MAX(CASE WHEN [Key]=1 THEN BooleanAnswer END) Key1,
MAX(CASE WHEN [Key]=2 THEN BooleanAnswer END) Key2,
MAX(CASE WHEN [Key]=3 THEN BooleanAnswer END) Key3,
MAX(CASE WHEN [Key]=4 THEN BooleanAnswer END) Key4,
MAX(CASE WHEN [Key]=5 THEN BooleanAnswer END) Key5,
MAX(CASE WHEN [Key]=6 THEN BooleanAnswer END) Key6,
MAX(CreationDateTimeUtc) MaxCreationDateTimeUtc,
QuestionId
FROM LevelEntries
WHERE LevelId=2
AND QuestionId IN(1,2,3,4,5,6)
GROUP BY UserId,MissionId,LevelId,QuestionId

Answer 2

You can use PIVOT for that purpose.
with Entries as
(
select UserId,
MissionId,
LevelId,
'Key' + cast([Key] as varchar) as [Key],
BooleanAnswer,
CreationDateTimeUtc,
QuestionId
from [Bakman].[dbo].[LevelEntries]
where LevelId = 2 and QuestionId in (1, 2, 3, 4, 5, 6)
)
select UserId,
MissionId,
LevelId,
Key1,
Key2,
Key3,
Key4,
Key5,
Key6,
CreationDateTimeUtc,
QuestionId
from Entries t
pivot
(
max(BooleanAnswer)
for [Key] in (Key1, Key2, Key3, Key4, Key5, Key6)
) p;
