SQL select, sum and group - sql

I'm struggling with an Access database:
I have a large database with the headers TAG, ZST, KL and R1H00 to R1H23 (24 of them, each one stands for one hour of a day) and I need to get a specific dataset out of it:
SELECT TAG, ZST, (R1H00 + R1H01 + R1H02 + R1H03 + R1H04 + R1H05 + R1H06 + R1H07 + R1H08 + R1H09 + R1H10 + R1H11 + R1H12 + R1H13 + R1H14 + R1H15 + R1H16 + R1H17 + R1H18 + R1H19 + R1H20 + R1H21 + R1H22 + R1H23) AS TOTAL
FROM Klassendaten
WHERE KL = "SWISS7_PW"
So far so good, but the result contains many items with the same ID (ZST). I need to sum all entries with the same ZST, but I couldn't manage to do it so far. (I tried to use the GROUP BY statement, but that only results in errors)
Any experienced SQL people here that could help me with this?


use group by
SELECT TAG, ZST, sum(R1H00 + R1H01 + R1H02 + R1H03 + R1H04 + R1H05 + R1H06 + R1H07 + R1H08 + R1H09 + R1H10 + R1H11 + R1H12 + R1H13 + R1H14 + R1H15 + R1H16 + R1H17 + R1H18 + R1H19 + R1H20 + R1H21 + R1H22 + R1H23) AS TOTAL
FROM Klassendaten
WHERE KL = "SWISS7_PW"
GROUP BY TAG, ZST;


Use the Sum() function
SELECT TAG, ZST, Sum(R1H00 + R1H01 + R1H02 + R1H03 + R1H04 + R1H05 + R1H06 + R1H07 + R1H08 + R1H09 + R1H10 + R1H11 + R1H12 + R1H13 + R1H14 + R1H15 + R1H16 + R1H17 + R1H18 + R1H19 + R1H20 + R1H21 + R1H22 + R1H23) AS TOTAL
FROM Klassendaten
where ZST = '(Whatever it is)'
group by tag, zst

How to optimise below sql query

I have a backend limitation that the Resultant column which is of decimal type(aban) can not have more than 1000 characters in it formula.
How to optimise this query?
I have tried using tempTable but results are not as expected.
aban =
CASE
WHEN (
sum(isnull(a.callshandled,0)) + sum(isnull(a.totalcallsaband,0)) + sum(isnull(a.incompletecalls,0)) + sum(isnull(a.returnbusy,0)) + sum(isnull(a.returnring,0)) + sum(isnull(a.icrdefaultrouted,0)) + sum(isnull(a.ndr,0)) + sum(isnull(a.overflowout,0)) + sum(isnull(a.callsrona,0)) + sum(isnull(a.returnrelease,0)) + sum(isnull(a.callsroutednonagent,0)) + sum(isnull(a.shortcalls,0)) + sum(isnull(a.agenterrorcount,0)) + sum(isnull(a.errorcount,0))
)
= 0 THEN
0
ELSE (sum(isnull(a.totalcallsaband,0)) * 1.0) / (sum(isnull(a.callshandled,0)) + sum(isnull(a.totalcallsaband,0)) + sum(isnull(a.incompletecalls,0)) + sum(isnull(a.returnbusy,0)) + sum(isnull(a.returnring,0)) + sum(isnull(a.icrdefaultrouted,0)) + sum(isnull(a.networkdefaultrouted,0)) + sum(isnull(a.overflowout,0)) + sum(isnull(a.callsrona,0)) + sum(isnull(a.returnrelease,0)) + sum(isnull(a.callsroutednonagent,0)) + sum(isnull(a.shortcalls,0)) + sum(isnull(a.agenterrorcount,0)) + sum(isnull(a.errorcount,0)))
END
,
Optimise the query in such a way that number of characters in formula is less then 1000 and resultant column should have same value before and after query optimisation.

Please try this way:
DECLARE #dividend int = 10;
DECLARE #divisor int = 0;
SELECT COALESCE(#dividend / NULLIF(#divisor,0), 0);
So you can avoid duplicate calculation for divisor.

Eliminating multiple delimiters in single column in oracle

My table has single column info
Info
+aname + + + + + + +ano+ + + + + + + + + +agender+ + + + + + + + + + + + +arace
I should get output like
aname+ano+agender+arace
I have to eliminate multiple delimiters and replace with single +
I tried with regexp_replace and trim and working as below
select trim(REGEXP_REPLACE('+aname + + + + + + +
+ano + + + + + + + +
+agender+ + + + + + + + + + +
+arace', '\ + + ', '+'),'+') from dual;
i get output as
aname+++++++ano+++++++agender++++++++++arace

This regexp does the trick: '\++'
select REGEXP_REPLACE('+aname++++++ano+++++++++agender++++++++++++arace', '\++', '+') from dual;
To get rid of the leading + (like in your example), use ltrim (or trim to remove trailing + too).
select ltrim(REGEXP_REPLACE('+aname++++++ano+++++++++agender++++++++++++arace', '\++', '+'),'+') from dual;

Subquery returned more than 1 value. This is not permitted when the subquery follows =, !=, <,

When I run the following query I get the above error. I realize this is because the subquery is returning more than 1 result but am not sure how to fix it.

Any help is greatly appreciated, I've tried playing around with the query and yield the same results. I also tried adding a SELECT TOP 1 and got the same results for all policies.

You are doing:
update a
set a.covtypeplus = (SELECT distinct . . .
This suggests that you are expecting more than one result from that subquery. Not allowed.
Perhaps this will fix it, but it may not be what you want:
update a
set a.covtypeplus = (SELECT top 1 . . .

It appears to be this part that is messing you up:
from results_vehicle a
left join staging.coverage c on a.polnum =c.policyid
and a.polver = c.version and a.covcode = c.COVCODE
This must be generating more than one result for some values of a.covcode.

IF THEN Statement in SQL to OpenEdge

I'm struggeling with an if statement towards an OpenEdge database via ODBC. The query I have works like a charm, but Progress wants me to define the if statement different and I have no clue. Is there anyone who can define the correct query for me?
IF
{Crediteur code|type=string} = 'HOEFASTE'
BEGIN
(SELECT
inok."vest-kd-arvo"+RTRIM('-') + RIGHT(CAST((inok."inok-nr" + 1000000) AS varchar(7)),6) AS inokvalue
,RTRIM("leso-kd")+RTRIM('-')+inok."vest-kd-arvo"+RTRIM('-')+CAST("inok-nr"AS varchar(6)) AS inokdisplay
,RIGHT(CAST((inok."inok-nr") AS varchar(7)),6) + '-' + inok."vest-kd-arvo" + '-' + RTRIM("leso-kd") AS inoknr
,RTRIM("leso-kd") AS soortfact
FROM
PUB.inok
WHERE
inok."vcdc-nr" = {Administratie|type=int32}
AND inok."inss-kd" NOT IN ('H','G')
)
ELSE
(SELECT
inok."vest-kd-arvo"+RTRIM('-') + RIGHT(CAST((inok."inok-nr" + 1000000) AS varchar(7)),6) AS inokvalue
,RTRIM("leso-kd")+RTRIM('-')+inok."vest-kd-arvo"+RTRIM('-')+CAST("inok-nr"AS varchar(6)) AS inokdisplay

WHERE
inok."rela-kd-kre" = {Crediteur code|type=string}
AND inok."vcdc-nr" = {Administratie|type=int32}
AND inok."inss-kd" NOT IN ('H','G')
)
END

If I understand correctly, only your WHERE-clause is different, based on "Crediteur code".
You could move the IF inside of the WHERE-clause. That will leave you with a single SELECT-statement. Does this alternative work for you?
SELECT
inok."vest-kd-arvo"+RTRIM('-') + RIGHT(CAST((inok."inok-nr" + 1000000) AS varchar(7)),6) AS inokvalue
,RTRIM("leso-kd")+RTRIM('-')+inok."vest-kd-arvo"+RTRIM('-')+CAST("inok-nr"AS varchar(6)) AS inokdisplay
,RIGHT(CAST((inok."inok-nr") AS varchar(7)),6) + '-' + inok."vest-kd-arvo" + '-' + RTRIM("leso-kd") AS inoknr
,RTRIM("leso-kd") AS soortfact
FROM
PUB.inok
WHERE
inok."rela-kd-kre" = (CASE WHEN {Crediteur code|type=string} = 'HOEFASTE' THEN inok."rela-kd-kre" ELSE {Crediteur code|type=string} END)
AND inok."vcdc-nr" = {Administratie|type=int32}
AND inok."inss-kd" NOT IN ('H','G')

How can I use SUM() to sum my result array?

My current method to add the rows together is like so:
$totalxp = $row['Attackxp'] + $row['Defencexp'] + $row['Strengthxp'] + $row['Hitpointsxp'] + $row['Rangedxp'] + $row['Prayerxp'] + $row['Magicxp'] + $row['Cookingxp'] + $row['Woodcuttingxp'] + $row['Fletchingxp'] + $row['Fishingxp'] + $row['Firemakingxp'] + $row['Craftingxp'] + $row['Smithingxp'] + $row['Miningxp'] + $row['Herblorexp'] + $row['Agilityxp'] + $row['Thievingxp'] + $row['Slayerxp'] + $row['Farmingxp'] + $row['Runecraftxp'] + $row['Constructionxp'];
But then I saw SUM() and I tried this:
SELECT SUM(xp) FROM skills WHERE playerName='Undercover'
It works but I needed all the values of xp, so I tried adding %xp but it wont work.
How could I use the Sum() function to add all the rows up instead of straining PHP?

Aggregate functions (IE: SUM, MIN, MAX, COUNT, etc) don't work across columns--they work on the values for the specific column, based on the grouping (GROUP BY) and filteration (JOIN and/or WHERE clause).
To add up values across columns, you need to add them like you would for normal mathematical equations:
SELECT Attackxp + Defencexp + Strengthxp + Hitpointsxp + Rangedxp + Prayerxp + Magicxp + Cookingxp+ Woodcuttingxp + Fletchingxp + Fishingxp + Firemakingxp + Craftingxp + Smithingxp + Miningxp + Herblorexp + Agilityxp + Thievingxp + Slayerxp + Farmingxp + Runecraftxp + Constructionxp AS total_xp
FROM skills
WHERE playerName = 'Undercover'
If you have more than one record associated to a playername, then you can use an aggregate function:
SELECT SUM(Attackxp + Defencexp + Strengthxp + Hitpointsxp + Rangedxp + Prayerxp + Magicxp + Cookingxp+ Woodcuttingxp + Fletchingxp + Fishingxp + Firemakingxp + Craftingxp + Smithingxp + Miningxp + Herblorexp + Agilityxp + Thievingxp + Slayerxp + Farmingxp + Runecraftxp + Constructionxp) AS total_xp
FROM skills
WHERE playerName = 'Undercover'

That depend of the table data if each player is one entity (row) then is enaught to add columns:
SELECT Attackxp + Defencexp + Strengthxp + Hitpointsxp +Rangedxp + Prayerxp + Magicxp + Cookingxp + Woodcuttingxp + Fletchingxp + Fishingxp + Firemakingxp + Craftingxp + Smithingxp + Miningxp + Herblorexp + Agilityxp + Thievingxp + Slayerxp + Farmingxp + Runecraftxp + Constructionxp
As totalSkills FROM skills WHERE playerName = 'Undercover'
But is there more rows per player then You will need to sum also the rows
SELECT SUM(Attackxp + Defencexp + Strengthxp + Hitpointsxp +Rangedxp + Prayerxp + Magicxp + Cookingxp + Woodcuttingxp + Fletchingxp + Fishingxp + Firemakingxp + Craftingxp + Smithingxp + Miningxp + Herblorexp + Agilityxp + Thievingxp + Slayerxp + Farmingxp + Runecraftxp + Constructionxp)
As totalSkills FROM skills WHERE playerName = 'Undercover'

SELECT SUM(`Attackxp`) + SUM(`Defencexp`) + ... AS `total_sum`
FROM skills
WHERE playerName='Undercover'
