I am trying to get output to display multiple fields of data; where some of the data is the same but added more than once, into one row. eg workflow for actions, some action_cds can be used more than once and with more than one outcome.
Select ContactNo, name, address, action_cd,
action_due_date, Action_outcome
from Table1 which holds the Contact Actions data joined with Table2 which holds other relevant fields for output report.
I apologise if that sounds confusing. Basically there is a workflow which has many actions depending on what needs to happen, some actions could be used more than once with different due dates and different outcomes.
All this is required to be displayed in one row per Contact_No / Property in a report.
I have got myself confused trying various things. Went back to CASE but no luck.
SELECT distinct(ct.contact_no) AS 'ContactNo',
CASE WHEN (action_no = '1') THEN ac.action_cd + ' - ' +rd.act_desn end AS Act1,
CASE WHEN (action_no = '1') THEN ac.action_due_dt end As Act1DueDate,
CASE WHEN (action_no = '1') THEN ac.completed_dt end AS Act1COMPLETEDDATE,
CASE WHEN (action_no = '1') THEN ao.outcome end AS Act1OUTCOME,
CASE WHEN (action_no = '1') THEN ac.comment end AS Act1Comment,
CASE WHEN (action_no = '1') THEN ac.order_no end AS Act1ORDERNO,
CASE WHEN (action_no = '2') THEN ac.action_cd + ' - ' +rd.act_desn end AS Act2,
CASE WHEN (action_no = '2') THEN ac.action_due_dt end As Act2DueDate,
CASE WHEN (action_no = '2') THEN ac.completed_dt end AS Act2COMPLETEDDATE,

I'm trying to add a new calculated field (TravelTime) based on the NLength and NSpeedLimit fields from the following query
SELECT
sc.OBJECTID,
sn.Name,
case when hn.side = 'Right Side' then ''
else sc.LCity
end as LCity,
case when hn.side = 'Left Side' then ''
else sc.RCity
end as RCity,
case when hn.side = 'Right Side' then ''
else sc.LZip
end as LZip,
case when hn.side = 'Left Side' then ''
else sc.RZip
end as RZip,
sc.SHAPE.STLength() AS NLength,
ISNULL(sc.SpeedLimit,1) AS NSpeedLimit
FROM STREETNAME AS sn
INNER JOIN
STREETHASSTREETNAME AS hn ON
sn.GlobalID = hn.GlobalID AND
hn.Role = 'Primary'
INNER JOIN STREETCENTERLINE AS sc ON
hn.GlobalID = sc.GlobalID
The new calculated field is TravelTime = NLength/(NSpeedLimit*88)
but I can't add NLength/(NSpeedLimit*88) AS TravelTimein the select statement. I know I need to do a subquery but I don't know where it's supposed to go.
You can use Temp_tables, Derived tables or Common table expressions (CTE) to obtain the result. Simple approach would be Derived table as you dont need much more coding.
SELECT A.*
, A.NLength/(A.NSpeedLimit * 88) as [TravelTime]
FROM
(
SELECT
sc.OBJECTID,
sn.Name,
case when hn.side = 'Right Side' then ''
else sc.LCity
end as LCity,
case when hn.side = 'Left Side' then ''
else sc.RCity
end as RCity,
case when hn.side = 'Right Side' then ''
else sc.LZip
end as LZip,
case when hn.side = 'Left Side' then ''
else sc.RZip
end as RZip,
sc.SHAPE.STLength() AS NLength,
ISNULL(sc.SpeedLimit,1) AS NSpeedLimit
FROM STREETNAME AS sn
INNER JOIN
STREETHASSTREETNAME AS hn ON
sn.GlobalID = hn.GlobalID AND
hn.Role = 'Primary'
INNER JOIN STREETCENTERLINE AS sc ON
hn.GlobalID = sc.GlobalID
) AS A
You can add the columns in the FROM clause using apply:
SELECT . . .
v.NLength, v.NSpeedLimit,
(v.NLength / (v.NSpeedLimit*88)) as TravelTime
FROM STREETNAME sn JOIN
STREETHASSTREETNAME hn
ON sn.GlobalID = hn.GlobalID AND
hn.Role = 'Primary' JOIN
STREETCENTERLINE sc
ON hn.GlobalID = sc.GlobalID CROSS APPLY
(VALUES (sc.SHAPE.STLength(), COALESCE(sc.SpeedLimit, 1)
) v(NLength, NSpeedLimit)
Here is my sql query. I have column name "ExpenseBucketCoverage" in claim table in which I am storing bitwise operators store multiple values in one column like below
MED_COPAY = 1, MED_DED= 10, MED_COINS = 100, RX_COPAY = 1, RX_DED= 10, RX_COINS = 100
I want to replace hard coded value like MED_COPAY, MED_COINS, MED_DED, RX_DED, RX_COINS & RX_COPAY in query by using ExpenseBucketCoverage column value. Can some one please tell me how can I do that?
Someone has suggested me below soultion
retrieve data from claim and left joining the first matched record in eligibility. And then add custom code to loop through the datarows to split the rows by covered expense bucket, and set the service category code in-memory column based on the ExpenseBucketCoverage value for the claim.

I have a table StudentPeriodicAttendanceArchive which contains attendance information. I want to calculate total present and absent count.
Please suggest what should I do to improve the performance. I am using SQL Server 2008 R2
So I apologize for the wall of code, but I'm losing my mind over this tiny issue that is kicking my butt. The below query works perfectly and gives me everything I need to see with the exception of one column from DB.ACTIVITY_T. The moment I add said column, I immediately get duplicates where there is a MNT.ARRIVEDTS present. I can't seem to figure out why adding one more column to my select statement is causing this duplication. Maybe I'm too deep into this to see what's right in front of me? If you see what could be causing the error, please feel free to enlighten me.

Here are the results that you asked for.
REFNUMBER DERP ARRIVED MFSTNBR
123456789 [null] [null]
123456789 [null] [null]
123456789 2015-12-15 32304587
987654321 [null] [null]
987654321 [null] [null]
987654321 2015-12-13 49304483
Each null actually has a different MFSTNBR tied to it, but it's returning a null because it doesn't meet the '1234' or '5647' criteria. If I remove the destination criteria the nulls would be replaced with similar but different MFSTNBR.
My guess is you're getting multiple records from MNT when you only want one...
Likely MNT.Destination having 2 different values will result in 2 records for the max, not one.
Replace the
LEFT OUTER JOIN DB.ACTIVITY_T MNT
with
(SELECT MAX(DATE(MNT.ARRIVEDTS)) as "DERP ARRIVED", MFSTNBR
FROM DB.Activity_T
WHERE MNT.DESTINATION IN ('1234','5647')
GROUP BY MFSTNBR) as MNT
and eliminate the join critiera;
ND MNT.DESTINATION IN ('1234','5647') as it's taken care of by the inline view.
oh and modify the select to just look for "DERP ARRIVED" on the top most select.
Just my guess...

One of your inputs must be NULL.
You can probably solve this by identifying which it is and using COALESCE or ISNULL:
COALESCE(x, '')
ISNULL(x, '')
COALESCE is the standard ANSI way, ISNULL gives slightly better performance (although the difference is probably insignificant in most cases).
