I'm trying to map this particular SQL code for data warehousing purpose.
I have two columns (TARGET) and (NET_SALARY), purpose is to map NET_SALARY with 0 when TARGET is 700, in other cases sub-string net salary 1, 30
I'm receiving missing right parenthesis error
Both columns are varchar2 datatype
CASE
WHEN SRC_CUSTOMER.TARGET = '700' THEN SRC_CUSTOMER.NET_SALARY = '0'
ELSE SUBSTR(SRC_CUSTOMER.NET_SALARY,1,30)
END
If this is in a context of an ODI mapping/interface, you can only use SQL and not PL/SQL. You can't assign the value to SRC_CUSTOMER.NET_SALARY in the first THEN. You actually only need to set the value you want and it will be mapped to your target attribute.
Try with
CASE
WHEN SRC_CUSTOMER.TARGET = '700' THEN '0'
ELSE SUBSTR(SRC_CUSTOMER.NET_SALARY,1,30)
END
Move assignment before case keyword and put SRC_CUSTOMER.TARGET as the inner expression:
SRC_CUSTOMER.NET_SALARY =
CASE SRC_CUSTOMER.TARGET
WHEN '700' THEN '0'
ELSE SUBSTR(SRC_CUSTOMER.NET_SALARY,1,30)
END
Can be rewritten with decode function:
SRC_CUSTOMER.NET_SALARY = decode(SRC_CUSTOMER.TARGET,'700','0',SUBSTR(SRC_CUSTOMER.NET_SALARY,1,30))

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 used the following statement below:
Trim(IF FromDataSource.PID_VALID = 'Y' THEN FromDataSource.Person_ID ELSE #NULL)
Assuming you are using this code within a Transformer stage in DataStage
this will help
IF Trim(FromDataSource.PID_VALID) = 'Y' THEN Trim(FromDataSource.Person_ID) ELSE #NULL
Hint:
For you next question you might ask in this forum you should provide more details - do not let us guess. Also describe what you have tried and what error you got etc.
You can use case expression :
(CASE WHEN FromDataSource.PID_VALID = 'Y' THEN TRIM(FromDataSource.Person_ID) END)
else will return null if condition evaluate as false, you don't need to specify null.
If you want to set null if PID is not valid then->
IF FromDataSource.PID_VALID = 'Y' THEN trim(FromDataSource.Person_ID) ELSE setnull()
If you want to set empty when PID is not valid then->
IF FromDataSource.PID_VALID = 'Y' THEN trim(FromDataSource.Person_ID) ELSE ''
select fti.pa_serial_,fti.homeownerm_name,fti.ward_,fti.villagetole,fti.status,
ftrq.date_reporting, ftrq.name_of_recorder_reporting,
case
when fti.status='terminate' then ftrq.is_the_site_cleared ='1' end as is_the_site_cleared from fti join ftrq on ftrq.fulcrum_parent_id = fti.fulcrum_id
Here, is_the_site_cleared is text type of column which is converted into boolean by the when statement written and hence does not print as 1 and takes as true. I explicitly used print '1'. But this also did not work. My aim is to display '1' in the column 'is_the_site_cleared' when the value of fti.status='terminate'. Please help!!!
How about using integers rather than booleans?
select fti.pa_serial_, fti.homeownerm_name, fti.ward_,
fti.villagetole, fti.status, ftrq.date_reporting,
ftrq.name_of_recorder_reporting,
(case when fti.status = 'terminate' -- and ftrq.is_the_site_cleared = '1'
then 1 else 0
end) as is_the_site_cleared
from fti join
ftrq
on ftrq.fulcrum_parent_id = fti.fulcrum_id ;
From the description, I cannot tell if you want to include the condition ftrq.is_the_site_cleared = '1' in the when condition. But the idea is to have the then and else return numbers if that is what you want to see.
I have a query which returns a bunch of different data, however I want to have it replace all the values upon a certain condition.
What I have written below kind of gives me the result I want but not really. It creates a new column instead of replacing the other one:
SELECT
CASE
WHEN T4.[U_DestType] = '6'
THEN (SELECT
'Company Limited' AS [ShipToCode]
)
END AS [ShipToCode],
T2.[ShipToCode],
T6.[StreetS],
T6.[StreetNoS],
T6.[CityS],
T6.[ZipCodeS],
T6.[CountryS],
T5.[LicTradNum],
T2.[CardCode],
T4.[Phone1],
T4.[E_Mail],
T4.[U_DestType],
CASE
WHEN T4.[Country] = 'GB'
THEN 'EN'
ELSE T4.[Country]
END AS [Country],
T4.[U_ShortName]
FROM[...]
The end goal is to replace all of the columns with some preset values instead of just ShipToCode as above.
I tried putting an EXIST subquery after FROM too but that didn't work either.
Is this possible? I'm probably missing something very obvious.
Many thanks!
You can use an ELSE in your CASE expression to combine the two "columns":
CASE
WHEN T4.[U_DestType] = '6'
THEN (SELECT
'Company Limited' AS [ShipToCode]
)
ELSE T2.[ShipToCode]
END AS [ShipToCode],
And by the way, you didn't need to use a Sub-Select. This would work just as well and is easier to read:
CASE
WHEN T4.[U_DestType] = '6' THEN 'Company Limited'
ELSE T2.[ShipToCode]
END AS [ShipToCode],
I have a legacy SSIS package that needs updating. Specifically it used to only add new records and must now update and end date or delete records as appropriate. elsewhere in the package I've been using the Hashbytes function with great success to evaluate which rows need to be updated by taking matching datasets from both databases and then comparing them as part of a conditional split. The problem I'm having revolves around a case statement in the source query:
SELECT DISTINCT
DTBL_STUDENTS.STUDENT_ID,
FTBL_TEST_SCORES.TEST_STUDENT_GRADE,
DTBL_TESTS.TEST_NAME,
DTBL_SCHOOL_DATES.DATE_VALUE AS Assessment_Date,
DTBL_SCHOOL_DATES.SIS_SCHOOL_YEAR AS Assessment_Year,
left( CASE
WHEN FTBL_TEST_SCORES.TEST_SCORE_TEXT = 'NA'
THEN CASE
WHEN FTBL_TEST_SCORES.TEST_PRIMARY_RESULT_CODE = 'INTE' THEN 'High'
WHEN FTBL_TEST_SCORES.TEST_PRIMARY_RESULT_CODE = 'STRA' THEN 'Some'
WHEN FTBL_TEST_SCORES.TEST_PRIMARY_RESULT_CODE = 'BNCH' THEN 'Low'
WHEN FTBL_TEST_SCORES.TEST_PRIMARY_RESULT IN ('High', 'Some', 'Low') THEN FTBL_TEST_SCORES.TEST_PRIMARY_RESULT
ELSE FTBL_TEST_SCORES.TEST_SCORE_TEXT
END
ELSE CASE
WHEN FTBL_TEST_SCORES.TEST_SCORE_TEXT LIKE '%.0000'
THEN REPLACE(FTBL_TEST_SCORES.TEST_SCORE_TEXT, '.0000', '')
ELSE FTBL_TEST_SCORES.TEST_SCORE_TEXT
END
END,12) AS TEST_SCORE_TEXT,
CASE
WHEN FTBL_TEST_SCORES.TEST_SCORE_TEXT = 'NA'
THEN CASE
WHEN FTBL_TEST_SCORES.TEST_PRIMARY_RESULT_CODE = 'INTE' THEN '1'
WHEN FTBL_TEST_SCORES.TEST_PRIMARY_RESULT_CODE = 'STRA' THEN '3'
WHEN FTBL_TEST_SCORES.TEST_PRIMARY_RESULT_CODE = 'BNCH' THEN '4'
WHEN FTBL_TEST_SCORES.TEST_PRIMARY_RESULT = 'High' THEN '1'
WHEN FTBL_TEST_SCORES.TEST_PRIMARY_RESULT = 'Some' THEN '3'
WHEN FTBL_TEST_SCORES.TEST_PRIMARY_RESULT = 'Low' THEN '4'
ELSE '0'
END
ELSE FTBL_TEST_SCORES.TEST_SCORE_VALUE
END AS TEST_SCORE_VALUE,
FTBL_TEST_SCORES.TEST_PERCENTILE_SCORE,
DTBL_SCHOOLS.SCHOOL_HR_ID
FROM K12INTEL_DW.DTBL_TESTS
JOIN K12INTEL_DW.FTBL_TEST_SCORES ON FTBL_TEST_SCORES.TESTS_KEY =
DTBL_TESTS.TESTS_KEY
JOIN K12INTEL_DW.DTBL_SCHOOL_DATES ON DTBL_SCHOOL_DATES.SCHOOL_DATES_KEY =
FTBL_TEST_SCORES.SCHOOL_DATES_KEY
JOIN K12INTEL_DW.DTBL_STUDENTS ON DTBL_STUDENTS.STUDENT_KEY =
FTBL_TEST_SCORES.STUDENT_KEY
JOIN K12INTEL_DW.DTBL_SCHOOLS ON DTBL_SCHOOLS.SCHOOL_KEY =
FTBL_TEST_SCORES.SCHOOL_KEY
WHERE DTBL_SCHOOL_DATES.SIS_SCHOOL_YEAR = 2014
AND DTBL_STUDENTS.STUDENT_CURRENT_DISTRICT_CODE = '2180'
AND FTBL_TEST_SCORES.TEST_STUDENT_GRADE IN ('PS', 'PK', 'KG', '01', '02',
'03', '04', '05', '06', '07', '08')
AND DTBL_TESTS.TEST_VENDOR IS NOT NULL
AND FTBL_TEST_SCORES.TEST_HIGHEST_SCORE_INDICATOR IN ('Yes', '--')
The 3 values I need to hash for comparison are:
TEST_SCORE_TEXT
TEST_SCORE_VALUE
Assessment_Date
It looks like it's choking on TEST_SCORE_VALUE in the function:
HASHBYTES('SHA1',ISNULL(#Dware.TEST_SCORE_TEXT,'')+convert(varchar(10),ISNULL(TEST_SCORE_VALUE,''))+convert(varchar(50),(ISNULL(Assessment_Date,'')))) as SourceHash
This is where I get the error "Error converting data type varchar to numeric". I've tried putting my source query into a subquery and doing a select*, (function) from that source query. I've tried putting the case statement into the hashbytes function, and I've tried using a temp table. My assumption is that it's getting the underlying value rather than the value generated by the case statement but I don't know why,or how to fix it so that I get the numeric values I'm expecting/wanting.
Many thanks for any assistance!
Assuming FTBL_TEST_SCORES.TEST_SCORE_VALUE is numeric, then look at your CASE statement that creates TEST_SCORE_VALUE. You create a string by evaluating TEST_PRIMARY_RESULT_CODE and TEST_PRIMARY_RESULT, etc, but your final ELSE statement is probably returning a numeric value (FTBL_TEST_SCORES.TEST_SCORE_VALUE).
I believe Sql Server determines the output type of the CASE statement by the last return value. (In any case, itt has an algorithm for determining the return type when individual THEN statements are mixed.)
So, it sees your CASE statement as typed to whatever FTBL_TEST_SCORES.TEST_SCORE_VALUE is, which is probably inconsistent with the earlier varchar return values of the CASE statement.
Fix that, and the HASHBYTES function should work, as is.
+convert(varchar(10),ISNULL(TEST_SCORE_VALUE,''))
Turns out that should've been:
+convert(varchar(10),ISNULL(TEST_SCORE_VALUE,0))
and then it all worked fine.
