I have a SQL query where I am trying to replace null results with zero. My code is producing an error
[1]: ORA-00923: FROM keyword not found where expected
I am using an Oracle Database.
Select service_sub_type_descr,
nvl('Single-occupancy',0) as 'Single-occupancy',
nvl('Multi-occupancy',0) as 'Multi-occupancy'
From
(select s.service_sub_type_descr as service_sub_type_descr, ch.claim_id,nvl(ci.item_paid_amt,0) as item_paid_amt
from table_1 ch, table_" ci, table_3 s, table_4 ppd
where ch.claim_id = ci.claim_id and ci.service_type_id = s.service_type_id
and ci.service_sub_type_id = s.service_sub_type_id and ch.policy_no = ppd.policy_no)
Pivot (
count(distinct claim_id), sum(item_paid_amt) as paid_amount For service_sub_type_descr IN ('Single-occupancy', 'Multi-occupancy')
)
This expression:
nvl('Single-occupancy',0) as 'Single-occupancy',
is using an Oracle bespoke function to say: If the value of the string Single-occupancy' is not null then return the number 0.
That logic doesn't really make sense. The string value is never null. And, the return value is sometimes a string and sometimes a number. This should generate a type-conversion error, because the first value cannot be converted to a number.
I think you intend:
coalesce("Single-occupancy", 0) as "Single-occupancy",
The double quotes are used to quote identifiers, so this refers to the column called Single-occupancy.
All that said, fix your data model. Don't have identifiers that need to be quoted. You might not have control in the source data but you definitely have control within your query:
coalesce("Single-occupancy", 0) as Single_occupancy,
EDIT:
Just write the query using conditional aggregation and proper JOINs:
select s.service_sub_type_descr, ch.claim_id,
sum(case when service_sub_type_descr = 'Single-occupancy' then item_paid_amt else 0 end) as single_occupancy,
sum(case when service_sub_type_descr = 'Multi-occupancy' then item_paid_amt else 0 end) as multi_occupancy
from table_1 ch join
table_" ci
on ch.claim_id = ci.claim_id join
table_3 s
on ci.service_type_id = s.service_type_id join
table_4 ppd
on ch.policy_no = ppd.policy_no
group by s.service_sub_type_descr, ch.claim_id;
Much simpler in my opinion.
for column aliases, you have to use double quotes !
don't use
as 'Single-occupancy'
but :
as "Single-occupancy",

I'm using a sql query to export a database from my company's program.
Everything seems to be fine till I change the date on the "where" statement with a previous one.
Please find below the code:
SELECT p."Index", p."PSN" || CAST(p."PNR"as int) AS ID,
p."PSN" AS Serie, cast(p."PNR"as int) AS Numar,
pr."PINDate" AS r_gdate,
CASE WHEN pr."AsigEID"='10' THEN pr."PrimSUM" ELSE
pr."PrimSUM"*valuta1."EXCValue" END AS r_prima_lei,
CASE WHEN pr."AsigEID"='2'
THEN pr."PrimSUM"
ELSE CASE WHEN pr."AsigEID"='10' THEN pr."PrimSUM"/valuta2."EXCValue"
ELSE pr."PrimSUM"*valuta1."EXCValue"/valuta2."EXCValue"
END
END AS r_prima_eur,
CASE WHEN pr."AsigEID"='10' THEN pr."AsigSUM" ELSE
pr."AsigSUM"*valuta1."EXCValue" END as r_sa_lei,
CASE WHEN pr."AsigEID"='2'
THEN pr."AsigSUM"
ELSE CASE WHEN pr."AsigEID"='10' THEN pr."AsigSUM"/valuta2."EXCValue"
ELSE pr."AsigSUM"*valuta1."EXCValue"/valuta2."EXCValue"
END
END AS r_sa_eur,
pr."AsigStart", pr."AsigEnd", risc."Code", plink."Index"
FROM "PolsRisc" AS pr
LEFT JOIN "Pols" as p ON p."Index" = pr."PID"
LEFT JOIN "Riscs" as risc ON pr."RID" = risc."Index"
LEFT JOIN "PRLNK" plink ON plink."PTID" = p."PTID" AND plink."RID" = risc."Index"
LEFT JOIN "EXCValues" valuta1 ON valuta1."AtDate" = pr."AsigStart" AND valuta1."EID" = pr."AsigEID"
LEFT JOIN "EXCValues" valuta2 ON valuta2."AtDate" = pr."AsigStart" AND valuta2."EID"='2'
WHERE pr."PINDate" > '2020-08-01' AND pr."IsRezil" = 'false';
When I'm using '2020-08-01' the query works well. When I try to change it to a previous one eg. '2010-01-01' a get an error:
ERROR: invalid input syntax for integer: ""
SQL state: 22P02
I was looking for a solution on the previous posts but I didn't manage to solve this issue.
It looks like it is returning "" or a null value into one of the columns you are using integer logic for. The date change is just filtering out the data that would crash it.
You may need to use coalesce to reassign the nulls as 0 and then cast it back into being an int
select
cast(coalesce(table.column, 0) as int) as result
from table
I would advice to read the chapter http://www.postgresql.org/docs/current/interactive/sql-syntax-lexical.html#SQL-SYNTAX-CONSTANTS
. It's a brief and informative read.The cause for the error message is that '' is an empty string that has no representation in a numeric type like integer
I have an issue that I'm hoping you can help me with. I am trying to create charting data for performance of an application that I am working on. The first step for me to perform two select statements with my feature turned off and on.
SELECT onSet.testName,
avg(onSet.elapsed) as avgOn,
0 as avgOff
FROM Results onSet
WHERE onSet.pll = 'On'
GROUP BY onSet.testName
union
SELECT offSet1.testName,
0 as avgOn,
avg(offSet1.elapsed) as avgOff
FROM Results offSet1
WHERE offSet1.pll = 'Off'
GROUP BY offSet1.testName
This gives me data that looks like this:
Add,0,11.4160277777777778
Add,11.413625,0
Delete,0,4.5245277777777778
Delete,4.0039861111111111,0
Evidently union is not the correct feature. Since the data needs to look like:
Add,11.413625,11.4160277777777778
Delete,4.0039861111111111,4.5245277777777778
I've been trying to get inner joins to work but I can't get the syntax to work.
Removing the union and trying to put this statement after the select statements also doesn't work. I evidently have the wrong syntax.
inner join xxx ON onSet.testName=offset1.testName
After getting the data to be like this I want to apply one last select statement that will subtract one column from another and give me the difference. So for me it's just one step at a time.
Thanks in advance.

I think you can use a single query with conditional aggregation:
SELECT
testName,
AVG(CASE WHEN pll = 'On' THEN elapsed ELSE 0 END) AS avgOn,
AVG(CASE WHEN pll = 'Off' THEN elapsed ELSE 0 END) AS avgOff
FROM Results
GROUP BY testName
I just saw the filemaker tag and have no idea if this work there, but on MySQL I would try something along
SELECT testName, sum(if(pll = 'On',elapsed,0)) as sumOn,
sum(if(pll = 'On',1,0)) as numOn,
sum(if(pll ='Off',elapsed,0)) as sumOff,
sum(if(pll ='Off',1,0)) as numOff,
sumOn/numOn as avgOn,
sumOff/numOff as avgOff
FROM Results
WHERE pll = 'On' or pll='Off'
GROUP BY testName ;
If it works for you then this should be rather efficient as you do not need to join. If not, thumbs pressed that this triggers another idea.
The difficulty you have with the join you envisioned is that the filtering in the WHERE clause is performed after the join was completed. So, you would still not know what records to use to compute the averages. If the above is not implementable with FileMaker then check if nested queries work. You would then
SELECT testName, on.avg as avgOn, off.avg as avgOff
FROM ( SELECT ... FROM Results ...) as on, () as off
JOIN on.testName=off.testName
If that is also not possible then I would look for temporary tables.
OK guys... thanks for the help again. Here is the final answer. The statement below is FileMaker custom function that takes 4 arguments (platform, runID, model and user count. You can see the sql statement is specified. FileMaker executeSQL() function does not support nested select statements, does not support IF statements embedded in select statements (calc functions do of course) and finally does not support the SQL keyword VALUES. FileMaker does support the SQL keyword CASE which is a little more powerful but is a bit wordy. The select statement is in a variable named sql and result is placed in a variable named result. The ExecuteSQL() function works like a printf statement for param text so you can see the swaps do occur.
Let(
[
sql =
"SELECT testName, (sum( CASE WHEN PLL='On' THEN elapsed ELSE 0 END)) as sumOn,
sum( CASE WHEN PLL='On' THEN 1 ELSE 0 END) as countOn,
sum( CASE WHEN PLL='Off' THEN elapsed ELSE 0 END) as sumOff,
sum( CASE WHEN PLL='Off' THEN 1 ELSE 0 END) as countOff
FROM Results
WHERE Platform = ?
and RunID = ?
and Model = ?
and UserCnt = ?
GROUP BY testName";
result = ExecuteSQL ( sql ; "" ; ""
; platform
; runID
; model
; userCnt )
];
getAverages ( Result ; "" ; 2 )
)
For those interested the custom function looks like this:
getAverages( result, newList, pos )
Let (
[
curValues = Substitute( GetValue( data; pos ); ","; ¶ );
sumOn = GetValue( curValues; 2 ) ;
countOn = GetValue( curValues; 3 );
sumOff = GetValue( curValues; 4 );
countOff = GetValue( curValues; 5 );
avgOn = sumOn / countOn;
avgOff = sumOff / countOff
newItem = ((avgOff - avgOn) / avgOff ) * 100
];
newList & If ( pos > ValueCount( data); newList;
getAverages( data; If ( not IsEmpty( newList); ¶ ) & newItem; pos + 1 ))
)
I'm having a Sql code like as follows
Select a.ItemCode, a.ItemDesc
From fn_BOM_Material_Master('A', #AsOnDate, #RptDate, #BranchID, #CompID)a
Left Outer Join fn_INV_AsOnDate_Stock(#StockDate, #AsOnDate, #RptDate, #BranchID, #CompID, #Finyear)b
On a.ItemCode=b.ItemCode and b.WarehouseCode<>'WAP'
and a.BranchID=b.BranchID and a.CompID=b.COmpID
Where a.ItemNatureCode = 'F' and a.BranchID = #BranchID and a.CompID = #CompID
Group by a.ItemCode, a.ItemDesc
Having sum(b.CBQty)<=0
Here the problem is that im passing an "#ShowZeroStock" value as as bit if the "#ShowZeroStock" value is '1' then Having should not be validated or (i.e: All values from the table should be returned including zero)
So How to change the query based on passed bit value "#ShowZeroStock"
I can Use "If else " condition at the top and remove having in else part, but for a lengthy query i can't do the same.
Is this the logic you want?
Having sum(b.CBQty) <= 0 or #ShowZeroStock = 1
Hi every one i want to use case statement in join using this query and got error
Select CONVERT(VARCHAR(10), SII.SIDATE,103)DATE,SII.SALEID,SII.ItemName,SI.TenancyID
FROM F_SALESINVOICEITEM SII
INNER JOIN F_SALESINVOICE SI ON SI.SALEID=SII.SALEID
INNER JOIN #TempTableSearch ts ON CASE
WHEN ts.ACCOUNTTYPE = '1' THEN ts.ACCOUNTID=SI.TENANCYID
WHEN ts.ACCOUNTTYPE='2' THEN ts.ACCOUNTID=SI.EMPLOYEEID
WHEN ts.ACCOUNTTYPE='3' THEN ts.ACCOUNTID=SI.SUPPLIERID
WHEN ts.ACCOUNTTYPE='4' THEN ts.ACCOUNTID=SI.SALESCUSTOMERID
Error
Incorrect syntax near '='.
Please help me to solve this error.
IT should be,
ON
ts.ACCOUNTID = CASE
WHEN ts.ACCOUNTTYPE = '1' THEN SI.TENANCYID
WHEN ts.ACCOUNTTYPE = '2' THEN SI.EMPLOYEEID
WHEN ts.ACCOUNTTYPE = '3' THEN SI.SUPPLIERID
WHEN ts.ACCOUNTTYPE = '4' THEN SI.SALESCUSTOMERID
END
Instead of using CASE, I'd much rather do this:
Select CONVERT(VARCHAR(10), SII.SIDATE,103)DATE,SII.SALEID,SII.ItemName,SI.TenancyID
FROM F_SALESINVOICEITEM SII
INNER JOIN F_SALESINVOICE SI ON SI.SALEID=SII.SALEID
INNER JOIN #TempTableSearch ts ON
(ts.ACCOUNTTYPE='1' AND ts.ACCOUNTID=SI.TENANCYID)
OR (ts.ACCOUNTTYPE='2' AND ts.ACCOUNTID=SI.EMPLOYEEID)
OR (ts.ACCOUNTTYPE='3' AND ts.ACCOUNTID=SI.SUPPLIERID)
OR (ts.ACCOUNTTYPE='4' AND ts.ACCOUNTID=SI.SALESCUSTOMERID)
To explain why the query didn't work for you: the syntax of the CASE requires an END at the end of the clause. It would work, as the other solutions proposed suggest, but I find this version to be more convenient to understand - although this part is highly subjective.
you can do this, so you have no chance to misspell something (note that ACCOUNTTYPE and ACCOUNTID used only when needed, you don't have to copy-paste it)
select
convert(varchar(10), SII.SIDATE,103) as DATE,
SII.SALEID, SII.ItemName, SI.TenancyID
from F_SALESINVOICEITEM as SII
inner join F_SALESINVOICE as SI on SI.SALEID = SII.SALEID
outer apply (
'1', SI.TENANCYID
'2', SI.EMPLOYEEID
'3', SI.SUPPLIERID
'4', SI.SALESCUSTOMERID
) as C(ACCOUNTTYPE, ACCOUNTID)
inner join #TempTableSearch as ts on
ts.ACCOUNTTYPE = C.ACCOUNTTYPE and ts.ACCOUNTID = C.ACCOUNTID
You have syntax error. You are missing END there.
You must understand that CASE ... END block is NOT equivalent to IF { } from C-like languages. Much rather this is equivalent to elaborate version of ... ? ... : ... operator from C-like languages. What it means that the WHOLE CASE block must essentially evaluate to single value and that this value has to be the same type no matter which case of the block is executed. This means that:
CASE
WHEN ts.ACCOUNTTYPE = '1' THEN ts.ACCOUNTID=SI.TENANCYID ...
END
Is fundamentally incorrect unless you work on a version of database that will allow you bool value as a value (SQL Server won't allow it for example but I think some of MySQL version used to allow it - not sure about this). You probably should write something like:
CASE
WHEN ts.ACCOUNTTYPE = '1' AND ts.ACCOUNTID=SI.TENANCYID THEN 1
WHEN ts.ACCOUNTTYPE='2' AND ts.ACCOUNTID=SI.EMPLOYEEID THEN 1
WHEN ts.ACCOUNTTYPE='3' AND ts.ACCOUNTID=SI.SUPPLIERID THEN 1
WHEN ts.ACCOUNTTYPE='4' AND ts.ACCOUNTID=SI.SALESCUSTOMERID THEN 1
ELSE 0
END = 1
Notice how the whole CASE block evaluates to 1 or 0 and then it is compared to 1. Of course instead of 4 WHEN's you could use one WHEN with combination of AND's, OR's and ( ) brackets. Of course in this particular case answer by #ppeterka 66 is correct as CASE is not suited for what you really wanted to do - I'm just trying to clarify what CASE really is.
This is the only place that I get all answer ;)
I want to select :
SELECT
RTRIM(LTRIM(il.Num_bloc)) AS Bloc,
RTRIM(LTRIM(il.num_colis)) AS Colis,
cd.transporteur AS Coursier,
cd.origine AS Origine,
cd.destination AS Destinataire,
cd.adresse AS [Adresse Destinataire],
cd.poids AS Poids,
il.Signataire, il.num_cin AS CIN, il.date_livraison AS [Date Livraison]
FROM
dbo.cd
INNER JOIN
dbo.il ON cd.bloc = il.Num_bloc AND dbo.cd.colis = dbo.il.num_colis
WHERE
(il.Num_bloc = RTRIM(LTRIM(#ParamBloc)))
AND (il.num_colis = RTRIM(LTRIM(#ParamColis)))
In the way of getting result if the user put ether #ParamBloc or #ParamColis
Try using IsNull() function.
A simple query would go like this
Select * from yourTable
Where
Num_bloc = ISNULL(#ParamBloc, Num_block) AND
num_colis = ISNULL(#ParamColis, num_colis)
The second parameter would make the expression to true if the #parameter Bloc or Colis is null. This query would be useful for all 4 possible combination of these two parameter.
