derive 2 fields SPEED_UPGRADE and TV_PACKAGE from 3 tables - teradata

I need to derive 2 fields SPEED_UPGRADE and TV_PACKAGE from 3 tables. I have written code below. I am not getting correct count of 'SPEED' and 'TV' which are falling between start_dt and END_DT. rather it is giving me count of all 'SPEED' and 'TV'. Kindly optimise my query .
select <few columns>,
count (case WHEN Cast('2021-11-09 00:00:00' AS TIMESTAMP(0))
BETWEEN a.START_DT AND Coalesce(a.END_DT,Cast('9999-12-31 00:00:00' AS TIMESTAMP FORMAT 'Y4-MM-DDBHH:MI:SS')) AND b.VOUCHER_TYPE_CD='SPEED'
then 1
ELSE 0
end) SPEED_UPGRADE,
count(case WHEN Cast('2021-11-09 00:00:00' AS TIMESTAMP(0))
BETWEEN a.START_DT AND Coalesce(a.END_DT,Cast('9999-12-31 00:00:00' AS TIMESTAMP FORMAT 'Y4-MM-DDBHH:MI:SS')) AND b.VOUCHER_TYPE_CD='TV'
then 1
ELSE 0
end) TV_PACKAGE

I want to create sub query in stored proc in oracle the following query giving error too many values

I want to add this query in stored procedure but it gives an error: ORA-00913: too many values
Select SUM(CONNMASS.CONN_BILLAMOUNT) as Revenuebilled,
count(CONNMASS.CONN_BILLEDUNITS) AS volumebilled,
count(MASSBILL.BM_lo_id) as normalbilled,
( SELECT COUNT(CASE WHEN SRM_DISCON_STATUS_ID = 3 THEN 1 END) AS ACTIVE_CONNECTIONS,
COUNT(CASE WHEN SRM_DISCON_STATUS_ID = 2 THEN 1 END) AS DISC_CONNECTIONS
from Connection_master)
from CONNECTION_MASTER CONNMASS
left join BILLING_MASTER MASSBILL
on MASSBILL.CONN_SERVICE_NO = CONNMASS.CONN_SERVICE_NO;
The problem is that you are selecting multiple values in the sub-query. You can only select a single value in a sub-query in the SELECT clause.
However, you do not need the sub-query and appear to want:
Select SUM(CONNMASS.CONN_BILLAMOUNT) as Revenuebilled,
count(CONNMASS.CONN_BILLEDUNITS) AS volumebilled,
count(MASSBILL.BM_lo_id) as normalbilled,
COUNT(CASE SRM_DISCON_STATUS_ID WHEN 3 THEN 1 END) AS ACTIVE_CONNECTIONS,
COUNT(CASE SRM_DISCON_STATUS_ID WHEN 2 THEN 1 END) AS DISC_CONNECTIONS
from CONNECTION_MASTER CONNMASS
left join BILLING_MASTER MASSBILL
on MASSBILL.CONN_SERVICE_NO = CONNMASS.CONN_SERVICE_NO;
If you did want the sub-queries then:
Select SUM(CONNMASS.CONN_BILLAMOUNT) as Revenuebilled,
count(CONNMASS.CONN_BILLEDUNITS) AS volumebilled,
count(MASSBILL.BM_lo_id) as normalbilled,
( SELECT COUNT(CASE SRM_DISCON_STATUS_ID WHEN 3 THEN 1 END)
from Connection_master) AS ACTIVE_CONNECTIONS,
( SELECT COUNT(CASE SRM_DISCON_STATUS_ID WHEN 2 THEN 1 END)
from Connection_master) AS DISC_CONNECTIONS
from CONNECTION_MASTER CONNMASS
left join BILLING_MASTER MASSBILL
on MASSBILL.CONN_SERVICE_NO = CONNMASS.CONN_SERVICE_NO;

WITH RECURSIVE looping through every day in the database and SUM number between two dates for each

I struggle with the last part below, the "with recursive". Of course I could loop over TimestampOrigin using C#, for every day in the database. Which would mean hundreds of times the same query. But it may be possible with one query using "with recursive".
Test data:
CREATE TABLE tblData(
Id INT, ComputerName TEXT, TimestampOrigin TEXT, Timestamp TEXT, Number INT
);
DELETE FROM tblData;
INSERT INTO tblData VALUES (1, "Computer1", '2021-02-10 12:00:00', '2021-02-27 12:00:00', 35);
INSERT INTO tblData VALUES (2, "Computer2", '2021-02-10 12:00:00', '2021-02-27 12:00:00', 24);
INSERT INTO tblData VALUES (3, "Computer3", '2021-02-09 12:00:00', '2021-02-26 12:00:00', 23);
INSERT INTO tblData VALUES (3, "Computer4", '2021-02-09 12:00:00', '2021-02-26 12:00:00', null);
INSERT INTO tblData VALUES (4, "Computer5", '2021-02-08 12:00:00', '2021-02-25 12:00:00', 7);
INSERT INTO tblData VALUES (5, "Computer6", '2021-02-08 12:00:00', '2021-02-25 12:00:00', 0);
INSERT INTO tblData VALUES (7, "Computer7", '2021-02-07 12:00:00', '2021-02-24 12:00:00', 9);
Query grouped by TimestampOrigin:
SELECT DATE(TimestampOrigin) AS TimestampOrigin,
SUM(CASE WHEN Number < 1 THEN 1 ELSE 0 END) AS Less1,
SUM(CASE WHEN Number >= 0 AND Number < 10 THEN 1 ELSE 0 END) AS Less10,
SUM(CASE WHEN Number >= 10 AND Number < 25 THEN 1 ELSE 0 END) AS Less25
FROM tblData WHERE Number NOT NULL GROUP BY DATE(TimestampOrigin) ORDER BY TimestampOrigin DESC
What I need is for every day the sum for the current up to Timestamp which is current day +17 days. Example for day 2021-02-08, sum of all rows with TimestampOrigin 2021-02-08 up to 2021-02-08 +17 days (column Timestamp).
Don't know if the extra column Timestamp which is noon time of TimestampOrigin +17 days is really required. But the over time query was the reason why I created it at the very beginning of the project.
SELECT DATE(TimestampOrigin) AS TimestampOrigin,
SUM(CASE WHEN Number < 1 THEN 1 ELSE 0 END) AS Less1,
SUM(CASE WHEN Number >= 0 AND Number < 10 THEN 1 ELSE 0 END) AS Less10,
SUM(CASE WHEN Number >= 10 AND Number < 25 THEN 1 ELSE 0 END) AS Less25
FROM tblData WHERE Number NOT NULL AND DATE(TimestampOrigin) >= DATE('2021-02-08') AND DATE(TimestampOrigin) <= DATE('2021-02-08', '+17 day')
Instead of executing the above query hundreds of times for each day and sum, I thought "with recursive" is the right approach". But was not able so far to make it work. Where to add the 17 days?
WITH RECURSIVE cte AS (
SELECT Id, ComputerName, Timestamp, DATE(Timestamp,'+1 day') totime, Number, TimestampOrigin
FROM tblData
UNION ALL
SELECT Id, ComputerName, DATE(Timestamp,'+1 day'), DATE(totime,'+1 day'), Number, TimestampOrigin
FROM cte
WHERE Number NOT NULL AND DATE(Timestamp,'+1 day') < DATE('2021-02-11')
)
SELECT DATE(TimestampOrigin),
SUM(CASE WHEN Number < 1 THEN 1 ELSE 0 END) AS Less1,
SUM(CASE WHEN Number >= 0 AND Number < 10 THEN 1 ELSE 0 END) AS Less10,
SUM(CASE WHEN Number >= 10 AND Number < 25 THEN 1 ELSE 0 END) AS Less25
FROM cte GROUP BY DATE(TimestampOrigin) ORDER BY DATE(TimestampOrigin) DESC
Expected result would be (Like when I would run the above query for each of the 4 days in the test data):
There is no need for a recursive CTE.
Join the distinct TimestampOrigins to the table under your condition and aggregate:
SELECT t1.TimestampOrigin,
SUM(t2.Number < 1) AS Less1,
SUM(t2.Number >= 0 AND t2.Number < 10) AS Less10,
SUM(t2.Number >= 10 AND t2.Number < 25) AS Less25
FROM (SELECT DISTINCT DATE(TimestampOrigin) TimestampOrigin FROM tblData) t1
INNER JOIN tblData t2
ON DATE(t2.TimestampOrigin) BETWEEN t1.TimestampOrigin AND DATE(t1.TimestampOrigin, '+17 days')
GROUP BY t1.TimestampOrigin
ORDER BY t1.TimestampOrigin DESC
See the demo.
Results:
TimestampOrigin
Less1
Less10
Less25
2021-02-10
0
0
1
2021-02-09
0
0
2
2021-02-08

2021-02-07

The result was wrong. I've found that my initial query was wrong. But with the solution from #forpas it worked at the end.
Initial single query
SELECT
SUM(Number < 1) AS Less1,
SUM(Number >= 1 AND Number < 10) AS Less10,
SUM(Number >= 10 AND Number < 25) AS Less25
FROM tblPCHardwareInformation WHERE UniqueInventoryKey IN
(
SELECT UniqueInventoryKey FROM tblPCHardwareInformation WHERE Number NOT NULL AND DATE(Timestamp) BETWEEN DATE('2020-10-09') AND DATE('2020-10-09', '+17 day') GROUP BY ComputerName ORDER BY Timestamp DESC
)
Result:
SELECT t1.TimestampOrigin,
SUM(t2.Number < 1) AS Less1,
SUM(t2.Number >= 1 AND t2.Number < 10) AS Less10,
SUM(t2.Number >= 10 AND t2.Number < 25) AS Less25
FROM (SELECT DISTINCT DATE(TimestampOrigin) TimestampOrigin FROM tblPCHardwareInformation) t1
INNER JOIN tblPCHardwareInformation t2
ON UniqueInventoryKey IN
(
SELECT UniqueInventoryKey FROM tblPCHardwareInformation WHERE Number NOT NULL AND DATE(Timestamp) BETWEEN DATE(t1.TimestampOrigin) AND DATE(t1.TimestampOrigin, '+17 day') GROUP BY ComputerName ORDER BY Timestamp DESC
)
GROUP BY t1.TimestampOrigin
ORDER BY t1.TimestampOrigin DESC

two counts in the same row

is't possible to set 2 counts in the same row.
my result from query is like this:
enter image description here
and i will that the end result seem like this :
enter image description here
and at the end build the precent count1 to count2
my attempt trough case was not successful : SELECT Date,Shift , CASE description WHEN 'Defects' THEN count ELSE 0 END AS Defect_Count , CASE description WHEN 'Total' THEN count ELSE 0 END AS Total_Count FROM ("Queries union)
Here you go. Hope this helps. Thanks.
MYSQL:
select
t.dates, t.shift,
sum(case when t.description = 'Defects' then t.counts else 0 end) as `Defects`,
sum(case when t.description = 'Total' then t.counts else 0 end) as `Total`
from (
select *
from tbl ) t
group by t.dates, t.shift
order by t.dates, t.shift
ORACLE:
SELECT dates, shift, defects , total
FROM
(
SELECT *
FROM tbl
)
PIVOT
(
sum(counts)
FOR description IN ('Defects' as defects, 'Total' as total)
)
ORDER BY dates
Result:
dates shift Defects Total

many Thanks is working for the first Step (counts in the same Row).
i will try now to build the percent (Defects to Total).
Thanks.
to build the percent (defects to Total):
select dates,shift,defects,total,round((100*defects/total),2) Percent2Total from(select t.dates, t.shift,
sum(case when t.description = 'Defects' then t.counts else 0 end) as 'Defects',
sum(case when t.description = 'total' then t.counts else 0 end) as 'Total'
from (
select *
from tbl ) t
group by t.dates, t.shift
)q order by dates,Shift.
may be it's possible to build that only with Pivot or?

How to get maximum column values across a row in Teradata sql?

I have a table named cnst_chrctrstc_abc with 10 columns (equ_gender1 - bb_population_flag) each row which contain numeric values (count) .
I want to get maximum 5 values out of each row across those 10 numeric columns.
The query I have looks something like the following ..
SEL
FROM
(
SEL
SUM(CASE WHEN COALESCE(act.equ_gender1,'') = COALESCE(inact.equ_gender1,'') THEN 0 ELSE 1 END ) AS equ_gender1_chg_cnt,
SUM(CASE WHEN COALESCE(act.exp_ex_bmyr1,'') = COALESCE(inact.exp_ex_bmyr1,'') THEN 0 ELSE 1 END ) AS exp_ex_bmyr1_chg_cnt,
SUM(CASE WHEN COALESCE(act.equ_age1,'') = COALESCE(inact.equ_age1,'') THEN 0 ELSE 1 END ) AS equ_age1_chg_cnt,
SUM(CASE WHEN COALESCE(act.maritalstatus1,'') = COALESCE(inact.maritalstatus1,'') THEN 0 ELSE 1 END ) AS maritalstatus1_chg_cnt,
SUM(CASE WHEN COALESCE(act.person_type1,'') = COALESCE(inact.person_type1,'') THEN 0 ELSE 1 END ) AS person_type1_chg_cnt,
SUM(CASE WHEN COALESCE(act.homeowner,'') = COALESCE(inact.homeowner,'') THEN 0 ELSE 1 END ) AS homeowner_chg_cnt,
SUM(CASE WHEN COALESCE(act.dwelling_size,'') = COALESCE(inact.dwelling_size,'') THEN 0 ELSE 1 END ) AS dwelling_size_chg_cnt,
SUM(CASE WHEN COALESCE(act.lengthofresidence,'') = COALESCE(inact.lengthofresidence,'') THEN 0 ELSE 1 END ) AS lengthofresidence_chg_cnt,
SUM(CASE WHEN COALESCE(act.childrenage0_18,'') = COALESCE(inact.childrenage0_18,'') THEN 0 ELSE 1 END ) AS childrenage0_18_chg_cnt,
SUM(CASE WHEN COALESCE(act.bb_population_flag,'') = COALESCE(inact.bb_population_flag,'') THEN 0 ELSE 1 END ) AS bb_population_flag
FROM
(SEL * FROM arc_mdm_Tbls.cnst_chrctrstc_abc WHERE load_id=1024 AND cnst_chrctrstc_end_dt='9999-12-31' (DATE))act
LEFT JOIN
(SEL * FROM arc_mdm_Tbls.cnst_chrctrstc_abc WHERE load_id=1024 AND cnst_chrctrstc_end_dt<'9999-12-31' (DATE)
QUALIFY ROW_NUMBER() OVER (PARTITION BY cnst_mstr_id ORDER BY cnst_chrctrstc_strt_ts DESC)=1
)inact
ON act.cnst_mstr_id = inact.cnst_mstr_id
)X
I know SEL GREATEST would produce the maximum value out of each row . But I want 5 top values and assign a rank to them.
Something like for some row first five columns may hold the top 5 values and for some last five i.e. homeowner to bb_population_flag may hold the top 5 values.
so if the columns and values from cnst_chrctrstc_abc look something like the following
cdi_batch_id | a | b | c | d | e | f | g | h | i |j
1024 |116|105|102|100|117|119|108|104|101|121
so the select query should return me columns j,f,e,a,g having the top 5 values.
And then I would assign a rank to them accordingly .
Should it be done using unpivot or something ?
Thanks in advance.
Yes, you need to unpivot your result.
Before TD14.10 you will need a list of those column names, either as a table
create table ColumnList (col varchar(128));
Insert into ColumnList('equ_gender1' );
Insert into ColumnList('exp_ex_bmyr1' );
Insert into ColumnList('equ_age1' );
Insert into ColumnList('maritalstatus1' );
Insert into ColumnList('person_type1' );
Insert into ColumnList('homeowner' );
Insert into ColumnList('dwelling_size' );
Insert into ColumnList('lengthofresidence' );
Insert into ColumnList('childrenage0_18' );
Insert into ColumnList('bb_population_flag');
or on-thy-fly using a bulky
with ColumnList as
(
select * from (select 'equ_gender1' as Col) as dt union all
select * from (select 'exp_ex_bmyr1' as Col) as dt union all
select * from (select 'equ_age1' as Col) as dt union all
select * from (select 'maritalstatus1' as Col) as dt union all
select * from (select 'person_type1' as Col) as dt union all
select * from (select 'homeowner' as Col) as dt union all
select * from (select 'dwelling_size' as Col) as dt union all
select * from (select 'lengthofresidence' as Col) as dt union all
select * from (select 'childrenage0_18' as Col) as dt union all
select * from (select 'bb_population_flag' as Col) as dt
)
Then you CROSS JOIN to unpivot:
select
col,
case col
when 'equ_gender1' then equ_gender1
when 'exp_ex_bmyr1' then exp_ex_bmyr1
when 'equ_age1' then equ_age1
when 'maritalstatus1' then maritalstatus1
when 'person_type1' then person_type1
when 'homeowner' then homeowner
when 'dwelling_size' then dwelling_size
when 'lengthofresidence' then lengthofresidence
when 'childrenage0_18' then childrenage0_18
when 'bb_population_flag' then bb_population_flag
end as Counts,
rank() over (order by Counts desc) as rnk
FROM
(
your current select
) as dt
cross join ColumnList
qualify rnk <= 5
In TD14.10 you could utilize the TD_UNPIVOT function:
SELECT Col, rank() over (order by Counts desc) as rnk
from TD_UNPIVOT(
ON (
your current select
)
USING
VALUE_COLUMNS('Counts')
UNPIVOT_COLUMN('Col')
COLUMN_LIST('equ_gender1'
,'exp_ex_bmyr1'
,'equ_age1'
,'maritalstatus1'
,'person_type1'
,'homeowner'
,'dwelling_size'
,'lengthofresidence'
,'childrenage0_18'
,'bb_population_flag')
) dt
qualify rnk <= 5;
Edit:
Additionally you might replace your LEFT JOIN with a single OLAP-function. Depending on the number of rows per cnst_mstr_id this might be more efficient as you need a ROW_NUMBER anyway:
SEL
SUM(CASE WHEN COALESCE(equ_gender1,'') = COALESCE(last_equ_gender1,'') THEN 0 ELSE 1 END ) AS equ_gender1_chg_cnt,
...
FROM
( SELECT
min(equ_gender1) OVER (PARTITION BY cnst_mstr_id ORDER BY cnst_chrctrstc_strt_ts DESC rows between 1 following and 1 following) as equ_gender1,
...
FROM arc_mdm_Tbls.cnst_chrctrstc_abc
WHERE load_id=1024
qualify cnst_chrctrstc_end_dt= date '9999-12-31'
)act

SQL Server 2012 query to compute calculations

I am building a query within SQL Server that is calculating scores we receive for our surveys. We have a column called overall_score, where the user inputs a number from 1-5 as a rating. I am trying to create a stored procedure that will calculate ratings based off the scores.
Score rating = (Total count of scores 4 and 5)/(Total number of responses) * 100
I have three separate select statements that create results I need, but when I go to combine them together my output is 0.
Can someone please guide me on what I am doing wrong here?
Separate SQL Statements:
SELECT count(overall_score) FROM Layer1_DataMerge WHERE overall_score = 4;
SELECT count(overall_score) FROM Layer1_DataMerge WHERE overall_score = 5;
SELECT count(overall_score) FROM Layer1_DataMerge;
Combined together:
SELECT distinct
(
(
(SELECT count(overall_score) FROM Layer1_DataMerge WHERE Overall_Score = 4) +
(SELECT count(overall_score) FROM Layer1_DataMerge WHERE overall_score = 5)
) / (SELECT count(overall_score) FROM Layer1_DataMerge)
) AS CSAT
FROM Layer1_DataMerge;
Well the reason you're getting zero is because you're doing integer division. With integer division 1/3 = 0. You need to convert to floating-point arithmetic, plus you can do it all in one query:
SELECT 100.0 *
(SUM(CASE WHEN overall_score = 4 THEN 1 ELSE 0 END) +
SUM(CASE WHEN overall_score = 5 THEN 1 ELSE 0 END)) /
COUNT(overall_score)
or
SELECT 100.0 *
SUM(CASE WHEN overall_score IN (4,5) THEN 1 ELSE 0 END) /
COUNT(overall_score)
To only show 2 decimals you can either cast to a numeric type with 2 decimals:
SELECT CAST(
100.0 *
SUM(CASE WHEN overall_score IN (4,5) THEN 1 ELSE 0 END) /
COUNT(overall_score)
AS NUMERIC(5,2))
Or use STR to convert to a string:
SELECT STR(
100.0 *
SUM(CASE WHEN overall_score IN (4,5) THEN 1 ELSE 0 END) /
COUNT(overall_score)
,5,2)
