I have a table...
ProjectID UserID RoleID
101 1 10
101 2 10
102 2 10
102 3 10
103 1 10
Currently there is only one type of Role, role '10', but I'm wanting to add a new role, role '11', which will act as a lead. So any project that has a user with the role of '10', should have a lead. The user chosen to be lead will be based on a priorty list, in this example we'll say the order is 1, 2, 3.
Expected result...
ProjectID UserID RoleID
101 1 11
101 2 10
102 2 11
102 3 10
103 1 11
You can figure out which user has the highest priority by using row_number(). SQL Server let's you do this in an updatable CTE, so the query looks like this:
with toupdate as (
select t.*,
row_number() over (partition by projectid
order by (case when userid = 1 then 1
when userid = 2 then 2
when userid = 3 then 3
else 4
end
)
) as PriorityForLead
from table t
)
update toupdate
set RoleId = 11
where PriorityForLead = 1;

Can anyone help me out? I've tried using GROUP BY and SUM/COUNT and such, but I'm always getting more than one row per user. I'm sure it's something simple I'm missing.
Presumably, for your required result, you require:
select UserId, User_Name, SurveyId,
case when sum(isSkipped) > 0 then 1 else 0 end as Complete
from t
group by UserId, User_Name, SurveyId;
Since it's enough they completed one question to be considered complete then you can just choose max(isSkipped) for your complete status.
select UserID
,[User Name]
,SurveyID
,max(isSkipped) as Complete
from t
group by UserID, [User Name], SurveyID
UserID
User Name
SurveyID

Goal:
If a person has two candy number, number 1 should always display first. No need to display candy number 2.
If a person does not have number 1, it should display number 2 instead.
Display all data

Problem:
It doesn't work so well for me to display it.
Tried using case and end in where statement but the code didn't fit to the purpose.
Any idea?
select *
from
table
where
candynumber =
CASE WHEN b.MatchType = 1
THEN 1
ELSE 2
END
Thank you!
This can be using row_number() window function:
select Id, fId, Name, Candy_Number from (
select your_table.*, row_number() over(partition by fId order by Candy_Number) as rn from your_table
) t
where rn = 1
order by id
This gives one row per fId, with lower Candy_Number.
You can try this :
SELECT candyWrapper.ID,
candyWrapper.FID,
outerHardCandy.Name,
outerHardCandy.Number
FROM (SELECT innerSoftCandy.Name,
CASE
WHEN (SUM(innerSoftCandy.Number) = 3) OR (SUM(innerSoftCandy.Number) = 1) THEN 1
WHEN (SUM(innerSoftCandy.Number) = 2) THEN 2
END AS Number
FROM Candy innerSoftCandy
GROUP BY innerSoftCandy.Name
) outerHardCandy
INNER JOIN Candy candyWrapper ON (outerHardCandy.Name = candyWrapper.Name AND outerHardCandy.Number = candyWrapper.Number)
ORDER BY candyWrapper.ID

This is my table and data
id | owner | buyer
1 1 3
2 2 2
3 1 2
I want the result to be like this
user | totals
2 3
1 2
3 1
User field means owner and buyer.
Hope you all are understand.
Thanks ~
You can do this using union all and group by:
select user, count(*)
from ((select owner as user from t
) union all
(select buyer from t
)
) ob
group by user
order by user;
I am trying to Select Group ID, and minimum dates per clients ID.
This is sample data set.
ClientID GroupID DataDate
1 9 2016-05-01
2 8 2015-04-01
3 7 2016-07-05
1 6 2015-01-05
1 5 2014-11-12
2 4 2016-11-02
1 3 2013-02-14
2 2 2011-04-01
I wrote
SELECT
clientID, MIN(DataDate)
FROM sampleTable
GROUP BY clientID
But in this query, I do not have GroupID selected. I need to include GroupID to join another table.
If I do:
Select
ClientID, GroupID, MIN(DataDate)
FROM sampleTable
GROUP BY ClientID, GroupID
It won't really get minimum dates per client.
Could you help me. How I should do this?
You can use ROW_NUMBER instead:
SELECT
ClientID, GroupID, DataDate
FROM (
SELECT *,
rn = ROW_NUMBER() OVER(PARTITION BY ClientID ORDER BY DataDate)
FROM SampleData
) t
WHERE rn = 1
If you want to include ties, use RANK instead of ROW_NUMBER.
I hope i understood your question correctly .
You want to display min dates for each client id's
If my table has data like this:
CID GID D1
1 9 03-06-2016
1 6 01-06-2017
1 5 01-06-2015
1 3 01-06-2014
2 4 01-06-2017
2 8 01-06-2014
3 5 03-06-2016
2 4 01-06-2011
Output :
CID GID D1
1 3 01-06-2014
2 4 01-06-2011
3 5 03-06-2016
This is what i think you can go with .
select cx.cid,cx.gid, cx.d1 from cli cx where cx.d1=(select min(c1.d1) from cli c1 where c1.cid=cx.cid)
group by cx.cid,cx.gid,cx.d1
order by cx.gid
Hope it helps.
Looking for a SQL solution to the following problem

In response to PM 77-1,
My current method:
SELECT table1.user,table1.number
FROM table1
JOIN (
SELECT user,
CAST(MIN((COALESCE(priority,999) *
(10 ^ (5 - LEN(COALESCE(CAST(priority AS VARCHAR),'999'))))) +
lineitem) AS VARCHAR) AS selector
FROM table1 GROUP BY user
) AS table2
ON table1.user = table2.user
AND table1.lineitem = CAST(RIGHT(table2.selector, 1) AS int)
ORDER BY table1.user;
Use ROW_NUMBER:
SQL Fiddle
;WITH Cte AS(
SELECT *,
ROW_NUMBER() OVER(
PARTITION BY [User]
ORDER BY
CASE WHEN Priority IS NULL THEN 1 ELSE 0 END,
Priority,
LineItem
) AS rn
FROM tbl
)
SELECT
[User], LineItem, Number, Priority
FROM Cte
WHERE rn = 1
